During the present study average annual catch of Penaeus monodon during 2011 - 2013 was 281.29±9.67 ton, which contributed 0.41 % to total trawl net catches at Digha coast. The rate 43.41 kg/h. percentage P. shrimp 1.91% in landings Monthly mean were 28.13±0.97 t from nets. Peak observed June November with a maximum 56.46±1.97 September and lean December March minimum 6.12±0.21 t.

The medial and distal vasa deferentia and terminal ampullae of Penaeus setiferus and P. vannamei were studied by light and electron microscopy to assess their roles in spermatophore formation. The ascending medial vas deferens of each species consisted of 2 parallel epitheliumlined ducts, referred to as the spermatophoric and accessory ducts, with the accessory duct fitting into a groove along ...

An oral administration of fungal polysaccharide schizophyllan has augmented protective immune responses to Sendai virus infection in mice and the rodshaped DNA virus of Penaeus japonicus (RV-PJ) infection in Kuruma shrimps. When schizophyllan was administered orally at a dose of 50 or 100 mg/kg body weight per day, the survival rates after virus challenge were significantly higher than those of...

Chronic toxicity test was conducted for 28 days with post larval stages of Penaeus indicus to arsenic for studying the changes associated with growth pattern, specifying the length, weight and condition factor. Arsenic exposures produced significant (P < 0.05) effect in terms of length, weight and deteriorated the condition factor of the test animal. Differentiation in relation between the cond...

Juvenile shrimps (Penaeus monodon) weighing about 15-20 gms were procured from the grow-out ponds and reared under laboratory conditions. They were challenged with Vibrio parahaemolyticus MTCC 451 and their LD50 value was evaluated. The ascorbic acid and the histamine activity of both the control and experimental groups were assessed. The results showed a marked decline in both the parameters a...

Black tiger shrimp Penaeus monodon, European shore crab Carcinus maenas and spiny lobster Panulirus spp. can be affected by milky hemolymph syndrome (MHS). Four rickettsia-like bacteria (RLB) isolates of MHS originating from 5 geographical areas have been identified to date. The histopathology of the disease was characterized and a multiplex PCR assay was developed for detection of the 4 bacter...

BACKGROUND Persistent infection of Penaeus stylirostris densovirus (PstDNV) (also called IHHNV) and its non-infectious inserts in the black tiger shrimp, Penaeus monodon (P. monodon) genome are commonly found without apparent disease. Here, we introduced the method of multiplex PCR in order to differentiate shrimp with viral inserts from ones with the infectious virus. The method allowed us to ...

The responses of wheat Triticum aestivum, rice Oryza sativa, earthworms Eisenia foetida, and prawns Penaeus japonicus to combined acetochlor-Cu, Cd-Zn were studied in hydroponic and soil-culturing systems using the methods of ecotoxicology. In particular, systematically quantitative analyses were documented by field experiments. Results showed that ecotoxicological effects under the combined po...

This study analyzed the changes in metallothionein-like proteins (MTLPs) and Energy Reserves (ERs) in hepatopancreas and abdominal muscle of the white prawn Penaeus vannamei. Realistic metal concentration exposure for 10 days to Ni and Pb in solution revealed that juvenile prawns partially induce MTLP in hepatopancreas after Pb exposure. Ni was distributed equally between soluble and insoluble ...

Ig67.-The dissociation of potassium and glucose movement during glucagon-induced glycogenolysis was studied in the isolated rat liver utilizing a small volume perfusion apparatus. When glucagon was added to a preparation assumed t...
