Lamellidens marginalis (Lamarck, 1819) is one of the important candidate species for freshwater pearl production in India. In the present study, the length-weight, width-weight and height-weight relationships of L. marginalis maintained in the farm were examined from January 2015 to September 2016. Monthly sampling was carried out and a total of 10...

Demand and production of freshwater pearl mussel Lamellidens marginalis (Lamarck, 1819) have increased many folds in the last few decades. There are only very scanty reports of infective agents and their pathogenicity affecting this particular mussel species. Heavy infestation and mortality of L. marginalis were observed in the ponds of Freshwater...

This study was conducted in indoor, aerated plastic tubs to estimate the digestibility of dry matter and nutrients by the carps, Labeo fimbriatus (Bloch, 1795) and Cyprinus carpio Linnaeus, 1758, from three feed ingredients viz., azolla, soybean meal and silkworm pupa incorporated at levels ranging from 0-40% in a diet comprising equal amounts of r...

The present study was conducted to evaluate and generate a primary database on bivalve diversity found in the water bodies of Terai region of Eastern Himalaya, West Bengal, India. A total of 20 species belonging to two genus Lamellidens and Parreysia were recorded. The availability of maximum molluscs was observed during the summer months of April...

Puntius pulchellus, a medium carp is evaluated for its potential as a candidate species for species diversification in freshwater aquaculture. Two growth trials were conducted to evaluate its performance with other Indian major carps,Catla catla and Labeo rohita in poly culture conducted in outdoor stone pithed un-manured ponds. In the first trial,...

An experiment of 75 days duration was conducted in fertilized outdoor circular cement tanks (1,000 L) with soil base for evaluating the growth and survival of Labeo fimbriatus fry fed with pelleted feed containing varied levels of dried azolla (Azolla pinnata). The Control feed contained 45% groundnut oilcake plus 45% rice bran and 10% finger mille...

This experiment of 75 days duration was conducted in out-door circular cement tanks (1000 l) with added soil bottom. Growth and survival of Cirrhinus mrigala fry, fed with pelleted feed containing varied levels of dried azolla was evaluated. Tanks were fertilized initially with cow dung at 4 t ha-1 followed by 0.5 t ha-1 fortnightly. Additionally,...

An experiment was conducted to study the stress mitigation and growth enhancing role of dietary L-tryptophan (TRP) under thermal stress in rohu, Labeo rohita fingerlings for 45 days. Seven hundred and twenty fishes were distributed in three major groups that are ambient temperature (26 °C), 34 and 38 °C in triplicate following a complete randomized...

Efficacy of feeding with different live feeds as well as artificial feed on growth performance of black-spot barb Puntius filamentosus fry was evaluated by conducting a feeding experiment for a period of 45 days. The fishes (average weight - 121.93 mg; average length - 28.8 mm) were fed under four treatments viz., artificial feed, Tubifex worm, Art...

Successful development of immunoprophylaxis against freshwater fish lice Argulus siamensis (Wilson) depends on the proper identification of protective antigens. The present study was undertaken to determine the immunodominant polypeptides of the freshwater fish lice A. siamensis, which causes a major disease problem in freshwater aquaculture. Sever...

Snakeheads, also known as murrels or serpent-headed fish, are a peculiar group of freshwater fishes having accessory respiratory organ to utilize atmospheric air for respiration that enables them to thrive in oxygen depleted waters. They are native to Asia and Africa. It is an important food fish in its entire native range and is of considerable...

The crustacean ectoparasite, Argulus poses one of the major threats to carp culture due to absence of any suitable control measure. The study was undertaken to determine the expression of immune-related genes in three major immunocompetent organs viz., kidney, skin and liver of rohu (Labeo rohita) during experimental freshwater lice Argulus siamens...

The study was undertaken to determine the modulation in innate immune response of rohu (Labeo rohita) during experimental freshwater lice Argulus siamensis infection. Results showed that serum α-2 macroglobulin (α-2M) activity, ceruloplasmin level and alternative complement activity were significantly (P<0.05) lower in fish at different degrees of...

The study was undertaken to evaluate the non-specific immune responses of the Indian major carp, Labeo rohita naturally infested with different loads of the freshwater fish louse, Argulus siamensis. Results showed that glucose level and total antiprotease activity of serum were significantly higher in fish with different degrees of lice infestation...

The giant freshwater prawn, Macrobrachium rosenbergii de Man or scampi is an economically important farmed crustacean species all over the world. India contributes ~ 20% to the world's scampi aquaculture production, being ranked second in the world In recent years, the rapid expansion and intensification of culture practices have brought several di...

The innate immune system of fish is considered to be the first line of defence against a broad spectrum of pathogens and is more important for fish as compared with mammals. Lysozyme level or activity is an important index of innate immunity of fish and is ubiquitous in its distribution among living organisms. It is well documented that fish lysozy...

Lack of immune competence in the early stages of life leads to severe mortality in larval stages of different fish species including Indian major carp (IMC). Investigation through indirect enzyme linked immunosorbent assay (ELISA) and agglutination test revealed a significant increase in specific serum antibody response in the brood fish of Indian...

Shrimp culture as an industry has been contributing significantly to the export earning, employment generation, poverty alleviation and to the economic development of India in recent years. India’s vast coastal belt and condu- cive environment has led to the rapid expansion of shrimp farming activities. Culture practices are gradually be- ing inten...
