Kizhakudan Research Centre of CMFRI, Chennai 3f With the decline in many commercial fisheries worldwide and an ever increasing demand for seafood protein, there is a growing need for augmenting the production of high-protein, high-value resources like lobsters. Aquaculture remains the ideal measure to augment production and ensure conseNation, and even enhancement. of natural stocks. Aquaculture provides a two-pronged solution towards increasing the fish production through ., farming of hatchery-produced seed of commercially important finfishes and shellfishes , enhancing natural stocks by sea ranching hatchery-produced seed of commercially important finfishes and shellfishes Lobsters are among the most priced seafood delicacies enjoying a special demand in international markets. As against a world average annual productio'n of2.1 lakh tonnes, India's average annual lobster production is about 2000 tonnes. With the distinction of being perhaps, the only seafood resource in India's trade economy, which remains relatively low down the ladder in terms of quantity of production but brings in maximum foreign exchange, lobsters have been the subject of study for more than two decades now. -

Conservation Status and Population Density of Himalayan Serow (Capricornis sumatraensis) in Annapurna Conservation Area of Nepal Achyut Aryal1 Abstract Himalayan Serow ‘Capricornis sumatraensis’ population is isolated in a small patch of the southern part of Annapurna Conservation Area (ACA) with a population density of 1.17 individual/km2 and a population sex ratio of 1:1.6(Male: Female). A strong correlation was found between population (y) and pellets density (x) (y=0.011x-0.2619, R2-0.97). The major problems in the Serow habitat were habitat fragmentation & land use change, conflict between predator and villager, livestock grazing and poaching. The study was successful in providing information on the present status of Himalayan Serow in the ACA. cGgk'0f{ ;+/If0f If]qsf] blIf0fL efudf ;fgf] ´'08df ! .!& k|lt ju { ls=ld= hg3gTj / ! :! .^ (k'lnË::qLlnË) sf] cgkftdf' 5l§Psf' ] ;fgf ] o;sf ] hg;Vof+ PSnf?kdf] /xsf] ] 5 . hg;ªVof\ / jsfnfsf{} ] 3gTjlar 3lx/f ] ;DaGw /xsf] ] kfOof] . lxdfnog l;/f]sf] ;/+If0fsf d'Vo ;d:ofx?df jf;:yfg 6'lqmg' / hldgsf] k|of]udf abnfj, ufpFn] ljrsf] åGå, ufO{j:t' rl/r/0f / u}/sfg'gL lzsf/ x'g\ . lxdfnog l;/f] ;+/If0fsf nflu ;+/If0f lzIff, hgtfdf´ o;af/] r]tgf hufpg] sfo{qmd cfjZos b]lvPsf 5g\ . of] cWoogn] cGgk'0f{ If]qdf /xsf] lxdfnog l;/f]sf] cj:yfjf/] hfgsf/L lbg ;kmn ePsf] 5 .

Animal Spot Animal Spot Uses Intriguing Specimens from Cincinnati Museum Center’S Collections to Teach Children How Each Animal Is Unique to Its Environment
Animal Spot Animal Spot uses intriguing specimens from Cincinnati Museum Center’s collections to teach children how each animal is unique to its environment. Touch a cast of an elephant’s skull, feel a real dinosaur fossil, finish a three-layer fish puzzle, observe live fish and use interactives to explore how animals move, “dress” and eat. Case 1: Modes of Balance and Movement (Case design: horse legs in boots) Animals walk, run, jump, fly, and/or slither to their destination. Animals use many different parts of their bodies to help them move. The animals in this case are: • Blue Jay (Cyanocitta cristata) • Grasshopper (Shistocerca americana) • Locust (Dissosteira carolina) • Broad-wing damselfly (Family: Calopterygidae) • King Rail (Rallus elegans) • Eastern Mole (Scalopus aquaticus) • Brown trout (Salmo trutta) • Gila monster (Heloderma suspectum) • Damselfly (Agriocnemis pygmaea) • Pufferfish (Family: Tetraodontidae) • Bullfrog (Rona catesbrana) • Cicada (Family: Cicadidae) • Moths and Butterflies (Order: Lepidoptera) • Sea slugs (Order: Chepalaspidea) • Koala (Phascolarctos cinereus) • Fox Squirrel (Sciurus niger) • Giant Millipede (Subspecies: Lules) Case 2: Endo/Exoskeleton (Case design: Surrounded by bones) There are many different kinds of skeletons; some inside the body and others outside. The animals with skeletons on the inside have endoskeletons. Those animals that have skeletons on the outside have exoskeletons.

After macroscopic observation of snails, the hepatopancreas, digestive tract, sex organs, slime and haemolymph were isolated. These samples were examined using the flotation techniques and direct rubbing. Of the 360 snails sampled, 213 (59.3%) were infested, that is 147 (82.1%) for A. marginata and 66 (36.7%) for A. fulica respectively. The highest infestation rate was recorded on protozoans (41.4%) followed by nematode (24.7%). The most represented parasites were Trichodina achatinae (23.9%) and Strongyloides stercoralis (16.1%); while the least represented were cyst of Balantidium coli (8.1%), Enteromonas sp. (8.1%), cyst of Isospora sp. (7.8%), larva of Protostrongylus sp. (7.5%), cyst of Cryptosporidium sp. -

Raineri peninsula in Messina, (Sicily, Italy). They were reared in a tank at the Aquarium of Messina. Mussels, starfish, and holothurians were provided as feed for the tritons. Spawning occurred in November 2012, lasted for 15 days, yielding a total number of 500 egg capsules, with approximately 2.0-3.0 x 103 eggs/capsule. The snail did not eat during the month, in which spawned. Spawning behaviour and larval development of the triton was described.

The Gastropod Shell Has Been Co-Opted to Kill Parasitic Nematodes
www.nature.com/scientificreports OPEN The gastropod shell has been co- opted to kill parasitic nematodes R. Rae Exoskeletons have evolved 18 times independently over 550 MYA and are essential for the success of Received: 23 March 2017 the Gastropoda. The gastropod shell shows a vast array of different sizes, shapes and structures, and Accepted: 18 May 2017 is made of conchiolin and calcium carbonate, which provides protection from predators and extreme Published: xx xx xxxx environmental conditions. Here, I report that the gastropod shell has another function and has been co-opted as a defense system to encase and kill parasitic nematodes. Upon infection, cells on the inner layer of the shell adhere to the nematode cuticle, swarm over its body and fuse it to the inside of the shell. Shells of wild Cepaea nemoralis, C. hortensis and Cornu aspersum from around the U.K. are heavily infected with several nematode species including Caenorhabditis elegans. By examining conchology collections I show that nematodes are permanently fixed in shells for hundreds of years and that nematode encapsulation is a pleisomorphic trait, prevalent in both the achatinoid and non-achatinoid clades of the Stylommatophora (and slugs and shelled slugs), which diverged 90–130 MYA. Taken together, these results show that the shell also evolved to kill parasitic nematodes and this is the only example of an exoskeleton that has been co-opted as an immune system. The evolution of the shell has aided in the success of the Gastropoda, which are composed of 65–80,000 spe- cies that have colonised terrestrial and marine environments over 400MY1, 2. -
