Karen’s Blog, August 20 2009:

A few days ago I finally went on Cornell’s annual alumni field trip to Shoals Marine Laboratory, on an island off the coast of New Hampshire. Met a lot of nice and interesting people on the boat trip over—Hi Sue, hi Bob, Hi Louise and Stefan and Hannah, hi, Fern. We saw lots of sea birds and seals. We toured the island, watched the bird banding, visited labs, inspected some (very tidy) student dorms.

Cornell offers college-credit courses all summer; students come over for two week stays or longer. At lunch time I sat down with a bunch of students. We all started talking. The girl next to me looked at my name tag, startled, and said “Are you Karen Pryor?” Yes. She was very excited. “Your book changed my life.” Hmm. Too young for it to be Nursing Your Baby; she must mean Don’t Shoot the Dog; the new book’s only been available three weeks.

No, Lily Strassberg meant Reaching the Animal Mind, and got a jacketless and already well-used copy out of her back pack for me to sign.

Lily is 17. She has been clicker training dogs since she was ten, and now teaches public obedience classes. She read my story in Chapter 1 about training a hermit crab to ring a bell. So, for her class research project last week at the marine lab, she set out to train a crab to ring a bell. Her professor doubted it would work, but she was so excited about it, he let her try.

Lily collected some of the local hermit crabs around the island. They were very small and timid so she used the local green crab Carcinus maenas instead. (These are pointy-shelled Portunid crabs, like the blue crabs we eat on the East Coast, only of course they are green not blue.)

Lily used the same reinforcement procedure I did--feeding with forceps, using the movement of the forceps as the click. She shaped the behavior of shoving a hanging weight with a claw, an improvement over my more complicated job of pulling a string down.

Just to be safe, in spare moments across two days she trained two crabs, Crab A and Crab B, Abby and Bertha. She took good and thorough data, photographs, and video too. When she presented her project, the other students burst into applause. The professor said her study was ‘practically publishable.’ When the experiment was over, Lilly released Abby and Bertha back to the ocean in the same place where they were collected.

I was thrilled. So, apparently, were the crabs, and here’s why I think that.

For each session the crab had to be moved into a small experiment tank with a grid drawn on the floor (to measure exactly how far the crab came toward the target each time.) At first the crabs were hard to catch, and struggled mightily when lifted into the air. But soon, they got it—Oh, I’m flying to the place where I train them to feed me delicious stuff—and they just held still to be picked up by the shell, and relaxed completely in the air, legs hanging down calmly. Now I ask you: isn’t that cool? Clicker-wise ‘operant’ crabs?

What were the chances that out of 100 people or more in the room I would sit down next to Lily?

You will be hearing more about Lily, I bet.

Endangered Beauties

Today, 6940 animals are listed as ‘endangered’ on the International Union for Conservation of Nature’s (IUCN) Red List of Threatened Species. One of them is the Loggerhead Sea Turtle (Caretta caretta) caught in the picture below. The marine reptile, belonging to the family Cheloniidae (a family of sea turtles), is found in the Atlantic, Pacific, and Indian Oceans and the Mediterranean Sea, with a main occurrence along the southeastern coast of North America and in the Gulf of Mexico. One of the most popular nesting sites is Florida, where more than 67,000 nests are built per year.

There are various circumstances that contributed to the C. caretta being listed on the IUCN Red List. In earlier times the Loggerhead Sea Turtle was mainly threatened by humans due to exploitation of their tortoise shell, meat, eggs and their fat, used to produce cosmetics and potential remedies. Anthropogenic dangers nowadays are rather fishing trawls and untended fishing gear.

Another danger comes with the fact that loggerhead sea turtle females have to come ashore to build terrestrial nests. On their way back from the nest to the ocean, loggerhead hatchlings are hunted by several predators, such as crabs, toads, lizards, snakes and seabirds. After reaching the ocean, other hazards await the juveniles; fish, moray eels and portunid crabs. When nesting ashore, female loggerheads are exposed to further danger by flesh flies, feral dogs and humans. The red fox, which was introduced in Australia by British settlers in the 19th century, led to significant population reductions. On top of that, with only four eggs clutches every second or third year, Loggerhead Sea Turtles have and extremely low productive rate. Loggerheads reach sexual maturity within 17 to 33 years and their lifespan ranges from 47 to 67 years.

Organisations all over the world work for loggerhead conservation in various ways. In 2006 Turkish animal welfarists protected more than 600 clutches as they watched over a coast of 18 kilometers in length in Anamur, Turkey, as female loggerheads were laying eggs. If necessary nests are monitored to spot threats and sometimes, to protect them, endangered clutches are even relocated. Shrimp trawlers also have been mandated to carry so-called TEDs (Turtle Exclusion Devices) which reduce injuries and death to sea turtles by allowing them to exit the fishing net through special devices.

DIVERSITY OF BRACHYURAN CRABS IN AYIRAMTHENGU MANGROVE; A PART OF KAYAMKULAM BACKWATER, KERALA, INDIA | UTTAR PRADESH JOURNAL OF ZOOLOGY

In the estuarine ecosystem, mangroves play important roles in the conservation of biodiversity, energy flow, and provide a habitat and feeding ground for a large variety of species. Brachyuran crabs are ecologically significant and are considered an unavoidable part of the ecosystem of mangroves. Here we examine the current status in the Ayiramthengu mangrove of brachyuran crab diversity and seasonal variation in their distribution and abundance; a portion of Kayamkulam backwater during February 2017-January 2018. A total of 1364 specimens, comprising 13 species of brachyuran crabs belonging to 4 families and 8 genera, were found. Up to species level, 5 species of Portunid crabs belonging to 4 genera, 5 species of Grapsid crabs, 1 species of Sesarmid crabs and 2 species of Ocypodi crabs have been described. During the monsoon (43%), the species diversity was high, followed by post-monsoon (35%) and pre-monsoon (35%) diversity (22 percent ). In different seasons, salinity may be the explanation for the difference in the diversity of crabs. Shannon-Wiener diversity (H ') ranged from 1.922 to 2.355, the estimated values of different diversity indices ranged from 1.048 to 1.886, Margalef's species richness (d), Dominance Index (D) ranged from 0.1038 to 0.1497. For the protection of the Ayiramthengu area in general, conservation strategies are required. Please see the link :- https://mbimph.com/index.php/UPJOZ/article/view/1822

A Note on Portunid Crabs of Odisha Coast, India

Portunid crabs belonging to the genera, viz., Scylla, Portunus and Charybdis species mostly represent edible shellfishes with high quality meat content. These crabs are widely valued in domestic and export markets Nandi & Pramanik [1]. They are mostly marine species; estuarine forms are also not uncommon. In the eastern maritime States of India, Odisha coast is 480 km long with a continental shelf area of 32,000 sq km. In this coastal region there are a number of estuaries (Mahanadi, Rhushikulya, Bahuda, Brahmani-Baitarini) and a large brackish water lagoon, known as Chilka Lake, an important Ramsar site in India. All these coastal habitats support important fish and shell fish resources of the country. A perusal of literature as well as investigation undertaken by the authors reveals a total of 29 portunid crabs species belonging to three subfamilies and six genera from this coast including five new records

Seed production of commercially valuable portunid crab Portunus Sanguinolentus (Herbst)

Mass seed production technology was tried in the present study in three eyed crab, P. sanguinolentus. To enhance the survival, the larvae were offered with sufficient amount of enriched Artemia nauplii and B. plicatilis. During the experimental period the larvae were provided with cordial environmental parameters. In order to avoid cannibalism shelters were provided in the culture tanks. The total duration for zoea I and II required 3-4 days, while zoea III and IV took 2-3 days and megalopa required 6-7 days to metamorphose into crab instar stage. The complete larval development took a span of 15-18 days. The intermoult duration was 3.62±0.32, 3.68±0.37, 2.75±0.35, 2.56±0.51 and 6.50±0.40 days for zoea I, II, III, IV and megalopa respectively. The final survival rate from megalopa to first crab was 5.25%. The survival rate for each zoeal and megalopal stages are 71.75±2.36, 44.0±3.36, 34.5±4.79, 12.0±2.94 and 5.25% for zoea I, II, III, IV and megalopa respectively. A maximum of 28% of mortality was observed during the first zoeal stage itself and thereafter the mortality was gradually increased.

Callinectes sapidus

Callinectes sapidus

Blue Crab escaping from the net at Core Banks, North Carolina. Callinectes sapidus (from the Greek calli- = "beautiful", nectes = "swimmer", and Latin sapidus = "savory"), the blue crab, Atlantic blue crab, or regionally as the Chesapeake blue crab, is a species of crab native to the waters of the western Atlantic Ocean and the Gulf of Mexico, and introduced internationally. C. sapidus is of significant culinary and economic importance in the United States, particularly in Louisiana, the Chesapeake Bay, and New Jersey. It is the Maryland state crustacean and is the state's largest commercial fishery. Description Sexual dimorphism Females have a broad abdomen, similar to the shape of the dome of the United States Capitol building. Males have a narrow abdomen, resembling the Washington Monument. Callinectes sapidus is a decapod crab of the swimming crab family Portunidae. The genus Callinectes is distinguished from other portunid crabs by the lack of an internal spine on the carpus (the middle segment of the claw), as well as by the T-shape of the male abdomen. Blue crabs may grow to a carapace width of 23 cm (9.1 in). C. sapidus individuals exhibit sexual dimorphism. Males and females are easily distinguished by the shape of the abdomen (known as the "apron") and by color differences in the chelipeds, or claws. The abdomen is long and slender in males, but wide and rounded in mature females. A popular mnemonic is that the male's apron is shaped like the Washington Monument, while the mature female's resembles the dome of the United States Capitol. Claw color differences are more subtle than apron shape. The immovable, fixed finger of the claws in males is blue with red tips, while females have orange coloration with purple tips. A female's abdomen changes as it matures: an immature female has a triangular-shaped abdomen, whereas a mature female's is rounded. Other species of Callinectes may be easily confused with C. sapidus because of overlapping ranges and similar morphology. One species is the lesser blue crab (C. similis). It is found further offshore than the common blue crab, and has a smoother granulated carapace. Males of the lesser blue crab also have mottled white coloration on the swimming legs, and females have areas of violet coloration on the internal surfaces of the claws. C. sapidus can be distinguished from another related species found within its range, C. ornatus, by number of frontal teeth on the carapace. C. sapidus has four, while C. ornatus has six. The crab's blue hue stems from a number of pigments in the shell, including alpha-crustacyanin, which interacts with a red pigment, astaxanthin, to form a greenish-blue coloration. When the crab is cooked, the alpha-crustacyanin breaks down, leaving only the astaxanthin, which turns the crab to a red-orange or a hot pink color. Distribution Callinectes sapidus is native to the western edge of the Atlantic Ocean from Cape Cod to Argentina and around the entire coast of the Gulf of Mexico. It has recently been reported north of Cape Cod in the Gulf of Maine, potentially representing a range expansion due to climate change. It has been introduced (via ballast water) to Japanese and European waters, and has been observed in the Baltic, North, Mediterranean and Black Seas. The first record from European waters was made in 1901 at Rochefort, France. In some parts of its introduced range, C. sapidus has become the subject of crab fishery, including in Greece, where the local population may be decreasing as a result of overfishing. Ecology The natural predators of C. sapidus include eels, drum, striped bass, spot, trout, some sharks, humans, cownose rays, and whiptail stingrays. C. sapidus is an omnivore, eating both plants and animals. C. sapidus typically consumes thin-shelled bivalves, annelids, small fish, plants and nearly any other item it can find, including carrion, other C. sapidus individuals, and animal waste. C. sapidus may be able to control populations of the invasive green crab, Carcinus maenas; numbers of the two species are negatively correlated, and C. maenas is not found in the Chesapeake Bay, where C. sapidus is most frequent. Callinectes sapidus is subject to a number of diseases and parasites. They include a number of viruses, bacteria, microsporidians, ciliates, and others. The nemertean worm Carcinonemertes carcinophila commonly parasitizes C. sapidus, especially females and older crabs, although it has little adverse effect on the crab. A trematode that parasitizes C. sapidus is itself targeted by the hyperparasite Urosporidium crescens. The most harmful parasites may be the microsporidian Ameson michaelis, the amoeba Paramoeba perniciosa and the dinoflagellate Hematodinium perezi, which causes "bitter crab disease". Life cycle Eggs of C. sapidus hatch in high salinity waters of inlets, coastal waters, and mouths of rivers and are carried to the ocean by ebb tides. During seven planktonic (zoeal) stages blue crab larvae float near the surface and feed on microorganisms they encounter. After the eighth zoeal stage, larvae molt into megalopae. This larval form has small claws called chelipeds for grasping prey items. Megalopae selectively migrate upward in the water column as tides travel landward toward estuaries. Eventually blue crabs arrive in brackish water, where they spend the majority of their life. Chemical cues in estuarine water prompt metamorphosis to the juvenile phase, after which blue crabs appear similar to the adult form. Blue crabs grow by shedding their exoskeleton, or molting, to expose a new, larger exoskeleton. After it hardens, the new shell fills with body tissue. Shell hardening occurs most quickly in low salinity water where high osmotic pressure allows the shell to become rigid soon after molting. Molting reflects only incremental growth, making age estimation difficult. For blue crabs, the number of molts in a lifetime is fixed at approximately 25. Females typically exhibit 18 molts after the larval stages, while postlarval males molt about 20 times. Male blue crabs tend to grow broader and have more accentuated lateral spines than females. Growth and molting are profoundly influenced by temperature and food availability. Higher temperatures and greater food resources decrease the period of time between molts as well as the change in size during molts (molt increment). Salinity and disease also have subtle impacts on molting and growth rate. Molting occurs more rapidly in low salinity environments. The high osmotic pressure gradient causes water to quickly diffuse into a soft, recently molted blue crab's shell, allowing it to harden more quickly. The effects of diseases and parasites on growth and molting are less well understood, but in many cases have been observed to reduce growth between molts. For example, mature female blue crabs infected with the parasitic rhizocephalan barnacle Loxothylacus texanus appear extremely stunted in growth when compared to uninfected mature females. Blue crab may reach maturity within one year of hatching in the Gulf of Mexico, while Chesapeake Bay crabs may take up to 18 months to mature. As a result of different growth rates, commercial and recreational crabbing occur year-round in the Gulf of Mexico, while crabbing seasons are closed for colder parts of the year in northern states. Female blue crab with eggs Mating and spawning are distinct events in blue crab reproduction. Males may mate several times and undergo no major changes in morphology during the process. Female blue crabs mate only once in their lifetimes during their pubertal, or terminal, molt. During this transition, the abdomen changes from a triangular to a semicircular shape. Mating in blue crab is a complex process that requires precise timing of mating at the time of the female's terminal molt. It generally occurs during the warmest months of the year. Prepubertal females migrate to the upper reaches of estuaries where males typically reside as adults. To ensure that a male can mate, he will actively seek a receptive female and guard her for up to 7 days until she molts, at which time insemination occurs. Crabs compete with other individuals before, during, and after insemination, so mate guarding is very important for reproductive success. After mating, a male must continue to guard the female until her shell has hardened. Inseminated females retain spermatophores for up to one year, which they use for multiple spawnings in high salinity water. During spawning, a female extrudes fertilized eggs onto her swimmerets and carries them in a large egg mass, or sponge, while they develop. Females migrate to the mouth of the estuary to release the larvae, the timing of which is believed to be influenced by light, tide, and lunar cycles. Blue crabs have high fecundity: females may produce up to 2 million eggs per brood. Migration and reproduction patterns differ between crab populations along the East Coast and the Gulf of Mexico. A distinct and large scale migration occurs in Chesapeake Bay, where C. sapidus undergoes a seasonal migration of up to several hundred miles. In the middle and upper parts of the bay, mating peaks in mid to late summer, while in the lower bay there are peaks in mating activity during spring and late summer through early fall. Changes in salinity and temperature may impact time of mating because both factors are important during the molting process. After mating, the female crab travels to the southern portion of the Chesapeake, using ebb tides to migrate from areas of low salinity to areas of high salinity, fertilizing her eggs with sperm stored during her single mating months or almost a year before. Spawning events in the Gulf of Mexico are less pronounced than in estuaries along the East Coast, like the Chesapeake. In northern waters of the Gulf of Mexico, spawning occurs in the spring, summer, and fall, and females generally spawn twice. During spawning, females migrate to high salinity waters to develop a sponge, and return inland after hatching their larvae. They develop their second sponge inland, and again migrate to the higher-salinity waters to hatch the second sponge. After this, they typically do not reenter the estuary. Blue crabs along the southernmost coast of Texas may spawn year-round. Commercial importance Cooked blue crabs Cooked blue crabs, shown here on sale at a fish market in Washington, D.C., are red. Commercial fisheries for C. sapidus exist along much of the Atlantic coast of the United States, and in the Gulf of Mexico. Although the fishery has been historically centered on the Chesapeake Bay, contributions from other localities are increasing in importance. In the past two decades, the majority of commercial crabs have been landed in four states: Maryland, Virginia, North Carolina, and Louisiana. Weight and value of harvests since 2000 are listed below. Fishery value in millions of dollars (and percentage of national harvest weight) Year Maryland Virginia North Carolina Louisiana National 2000 31 (12.3) 24 (15.5) 37 (21.8) 34 (28.0) 164 2001 35 (16.3) 26 (15.8) 32 (20.2) 32 (26.3) 158 2002 30 (15.1) 21 (15.5) 33 (21.5) 31 (28.5) 147 2003 35 (16.3) 19 (12.6) 37 (25.0) 34 (28.1) 154 2004 39 (19.4) 22 (15.8) 24 (19.6) 30 (25.4) 146 2005 40 (21.9) 21 (16.4) 20 (16.0) 27 (23.9) 141 2006 31 (17.7) 14 (13.7) 17 (15.3) 33 (32.1) 126 2007 42 (19.6) 16 (16.0) 21 (13.6) 35 (28.7) 149 2008 50 (21.5) 18 (14.3) 28 (20.3) 32 (25.7) 161 2009 52 (22.0) 21 (18.6) 27 (16.8) 37 (30.1) 163 2010 79 (33.2) 29 (19.3) 26 (15.4) 30 (15.4) 205 2011 60 (25.3) 26 (19.6) 21 (14.9) 37 (21.7) 184 2012 60 (24.4) 25 (18.5) 23 (14.9) 39 (22.8) 188 2013 50 (17.9) 24 (18.0) 30 (16.5) 51 (28.8) 192 As early as the 1600s, the blue crab was an important food item for Native Americans and European settlers in the Chesapeake Bay area. Soft and hard blue crabs were not as valuable as fish but gained regional popularity by the 1700s. Throughout their range crabs were also an effective bait type for hook and line fisheries. Rapid perishing limited the distribution and hindered the growth of the fishery. Advances in refrigeration techniques in the late 1800s and early 1900s increased demand for blue crab nationwide. The early blue crab fishery along the Atlantic coast was casual and productive because blue crabs were extremely abundant. In the lower Chesapeake Bay, crabs were even considered a nuisance species because they frequently clogged the nets of seine fishermen. Early on, the blue crab fishery of the Atlantic states was well documented. Atlantic states were the first to regulate the fishery, particularly the Chesapeake states. For example, after observing a slight decline in harvest, the fishing commissions of Virginia and Maryland put size limits into place by 1912 and 1917 respectively. Catch-per-unit-effort at the time was determined by packing houses, or crab processing plants. The early history of the recreational blue crab fishery in the Gulf of Mexico is not well known. Commercial crabbing was first reported in the Gulf of Mexico in the 1880s. Early crab fishermen used long-handled dip nets and drop nets among other simple fishing gear types to trap crabs at night. Blue crab spoiled quickly, which limited distribution and hindered the growth of the fishery for several decades. The first commercial processing plant in Louisiana opened in Morgan City in 1924. Other plants opened soon after, although commercial processing of hard blue crabs was not widespread until World War II. Louisiana now has the world's largest blue crab fishery. Commercial harvests in the state account for over half of all landings in the Gulf of Mexico. The industry was not commercialized for interstate commerce until the 1990s, when supply markedly decreased in Maryland due to problems (see above) in Chesapeake Bay. Since then, Louisiana has steadily increased its harvest. In 2002, Louisiana harvested 22% of the nation's blue crab. That number rose to 26% by 2009 and 28% by 2012. The vast majority of Louisiana crabs are shipped to Maryland, where they are sold as "Chesapeake" or "Maryland" crab. Louisiana's harvest remained high in 2013, with 17,597 metric tons of blue crab valued at $51 million. In addition to commercial harvesting, recreational crabbing is very popular along Louisiana's coast. The Chesapeake Bay has had the largest blue crab harvest for more than a century. Maryland and Virginia are usually the top two Atlantic coast states in annual landings, followed by North Carolina. In 2013, crab landings were valued at $18.7 million from Maryland waters and $16.1 million from Virginia waters. Although crab populations are currently declining, blue crab fishing in Maryland and Virginia remains a livelihood for thousands of coastal residents. As of 2001, Maryland and Virginia collectively had 4,816 commercial crab license holders. Three separate licenses are required for each of the three major jurisdictional areas: Maryland, the Potomac River, and Virginia waters. While the Bay’s commercial sector lands the majority of hard crab landings and nearly all peeler or soft crab landings, the recreational fishery is also significant. In 2013, an estimated 3.9 million pounds of blue crab were harvested recreationally. Blue crab populations naturally fluctuate with annual changes in environmental conditions. They have been described as having a long-term dynamic equilibrium, which was first noted after irregular landings data in the Chesapeake in 1950. This tendency may have made it difficult for managers to predict the severe decline of the Chesapeake’s blue crab populations. Once considered an overwhelmingly abundant annoyance, the declining blue crab population is now the subject of anxiety among fishermen and managers. Over the decade between the mid-1990s to 2004, the population fell from 900 million to around 300 million, and harvest weight fell from 52,000 tons (115,000,000 lbs) to 28,000 tons (62,000,000 lbs). Revenue fell further, from $72 million to $61 million. Long term estimates say that the overall Chesapeake population decreased approximately 70% in the last few decades. Even more alarming, the number of females capable of reproducing, known as spawning age females, has plummeted 84% in the just a few decades. Survival and addition of juveniles to the harvestable crab population is also low. Many factors are to blame for low blue crab numbers, including high fishing pressure, environmental degradation, and disease prevalence. Many types of gear have been used to catch blue crabs along the Atlantic and Gulf Coasts. Initially people used very simple techniques and gear, which included hand lines, dip nets, and push nets among a variety of other gear types. The trotline, a long baited twine set in waters 5–15 feet deep, was the first major gear type used commercially to target hard crabs. Use of commercial trotlines is now mostly limited to the tributaries of the Chesapeake Bay. In the Gulf of Mexico, trotline use drastically declined after invention of the crab pot in 1938. Crab pots are rigid boxlike traps made of hexagonal or square wire mesh. They possess between two and four funnels that extend into the trap, with the smaller end of the funnel inside of the trap. A central compartment made of smaller wire mesh holds bait. Crabs attracted by odorant plumes from the bait, often an oily fish, enter the trap through the funnels and cannot escape. Species other than blue crab are often caught incidentally in crab pots, including fish, turtles, conch, and other crab species. Of important concern is the diamondback terrapin, Malaclemys terrapin. The blue crab and diamondback terrapin have overlapping ranges along the East and Gulf coasts of the United States. Because the funnels in a crab pot are flexible, small terrapins may easily enter and become entrapped. Traps are checked every 24 hours or less, frequently resulting in drowning and death of terrapins. Crab pot bycatch may reduce local terrapin populations to less than half. To reduce terrapin entrapment, bycatch reduction devices (BRDs) may be installed on each of the funnels in a crab pot. BRDs effectively reduce bycatch (and subsequently mortality) of small terrapins without affecting blue crab catch. Because of its commercial and environmental value, C. sapidus is the subject of management plans over much of its range. In 2012, the C. sapidus population in Louisiana was recognized as a certified sustainable fishery by the Marine Stewardship Council. It was the first and remains the only certified sustainable blue crab fishery worldwide. For the state to maintain its certification, it must undergo annual monitoring and conduct a full re-evaluation five years after the certification date. source - Wikipedia Dear friends, if you liked our post, please do not forget to share and comment like this.
