Background Carp fish, rohu ( Labeo rohita Ham.) is important freshwater aquaculture species of South-East Asia having seasonal reproductive rhythm. There is no holistic study at transcriptome level revealing key candidate genes involved in such circannual rhythm regulated by biological clock genes (BCGs). Seasonality manifestation has two contrasti...

Sailfin armoured catfish (Pterygoplichthys spp.), an alien invasive species of family Loricariidae has invaded extensively in wastewater-fed large aquaculture ponds (locally called 'bheries') of East Kolkata Wetlands (EKW), West Bengal, India. As there is no viable controlling method at present, commonly these fishes are removed by different physic...

Labeo catla is a widely cultured species in monoculture and polyculture systems of the Indian subcontinent. In this study, the complete mitochondrial genome sequence of catla was reconstructed from Oxford Nanopore sequence data. The mitochondrial genome is 16,600 bp in length (accession no. is MN830943) which is larger than the previously reported...

Although feed cost is the greatest concern in aquaculture, the inclusion of carbohydrates in the fish diet and their assimilation are still not well understood in aquaculture species. We identified molecular events that occur due to inclusion of high carbohydrates in the diets of genetically improved ‘Jayanti rohu’ Labeo rohita. To reveal transcrip...

Objective: Labeo catla (catla), one of the three Indian major carps, is native to the Indo-Gangetic riverine system of India as well as the rivers of Pakistan, Bangladesh, Nepal and Myanmar. Its higher growth rate and compatibility with other major carps, specific surface feeding habit, and consumer preference have increased its popularity in carp...

Live food organisms move in the water column and serve as a source of all the nutrients such as essential proteins, lipids, carbohydrates, vitamins, minerals, amino acids and fatty acids for larval stages of fish. Hence, they are commonly known as "living capsules of nutrition". Most of the fish and shell fish larvae in nature feed on these small p...

The recent climate change and anthropogenic activity affects the agricultural land/soil as well as aquaculture sector via salinization of the aquatic zone. The present study aimed to investigate the effect of salinity on genetically improved farmed rohu, Labeo rohita popularly known as Jayanti and evaluation of its physiological response towards co...

A 45-day experiment trial was conducted to determine the effect of graded levels of dietary ginger supplementation on growth and nutrient utilization of Cyprinuscarpio (Linnaeus; 1758) fingerlings. Fishes of uniform size (average weight 6.0-6.5 g) were divided into six experimental groups in triplicates following completely randomized design (CRD)....

The present study was conducted in the water bodies of East Kolkata Wetlands to generate a primary database on fish diversity of West Bengal, India. 71 indigenous fish species belonging to 27 families were identified. The family Cyprinidae represented the largest diversity accommodating 14 genera and 23 species. According to IUCN (International Uni...

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...

Mercury and cadmium are among the major heavy metal pollutants, contaminating aquatic ecosystems. These heavy metals were investigated in the present study for sub lethal toxicity on freshwater fish, Catla catla. The acute toxicity tests were conducted by static renewal bioassay method and 96 h LC50 value of mercury and cadmium to C. catla seed wer...

Genetic characterization of Puntius sarana with mitochondrial Cytochrome c oxidase I (COI) genes revealed that P. Sarana has 91% similarity with P. fasciatus followed by P. denisonii, P. chelynoides and P. brevis with 87, 86 and 86% similarity, respectively. Phylogenetic analysis also showed that P. sarana is closely related to P. fasciatus among a...

In the present study, Puntius sarana collected from Khandepar River were transported in live condition and acclimatized to captivity. The captive brood stock was successfully raised in FRP tank with a specially balanced fish diet and intermittently fed with Tubifex warms for a period of one month. Sex of brooders was identified based on morphologic...

In the present study, the efficacy of Letrozole (LET) and17α-methyltestosterone, a potent nonsteroidal aromatase inhibitor (AI), on gondal sex differentiation and sex reversal was examined in Mozambique tilapia (Oreochromis mossambicus). Among the different doses tried in experiment, LET 100 mg/kg, LET 200 mg/kg and MT-50(17α-methyltestosterone) pr...
