Spotted scat Scatophagus argus is a popular aquarium species around the world due to its colorful appearance, hardiness, slow growth, and calm behavior. It has also been admired as food fish mainly in South South-East Asian countries good nutrient quality with high protein content taste. Considering importance both ornamental fish, several researchers have studied on different aspects of morphology, feeding habit, reproductive biology, culture; but date no consolidated report available these...
The development of carp gonads in warm water (23°C) aquaria under controlled conditions is described. In this environment males mature at 6 months age. Females ripen 14 months, and by 15 25% these have started to spawn, whereas natural female European do not until they are 4 years old. Fishes lay all their eggs once, as evinced the finding partly‐spent ovaries. Sexual maturation ovaries has been described six stages, based on histological changes, associated with changes gonado‐somatic index...
Effect of dietary supplementation n-3 and n-6 polyunsaturated fatty acids (PUFA) on reproductive performances in both sexes an Indian major carp, Catla catla (Ham.), were investigated terms sperm quality, spawning response, fecundity spawn recovery over a consecutive 2-year period. Sperm count spermatocrit value the range 3.2–3.8 × 107 ml−1 80–82%, respectively, fish fed PUFA-enriched test diet, significantly higher (P < 0.01) than control diet (2.3–2.5 64–70%). Spawning response group was...
Length-weight relationship is the most commonly used analysis which has been for several purposes in fisheries field among estimation of weight from length popular one. The present study performed to analyze length-weight Mystus tengara , a freshwater catfish Indian subcontinent. Total Length and Body Weight studied specimens have observed vary 7.2-11.3 cm (male), 7.3-11.7 (female) 3.43-13.63 g 2.83-14.88 (female). calculated regression coefficient ( b ) values are 2.941, 3.119 3.071 male,...
Reproductive biology of female amphidromous croaker Johnius coitor (Hamilton, 1822) was studied for the first time from various freshwater stretches Ganga river basin, India in relation to climatic variability. The species showed high spatial variation reproductive phenology and capable breeding during pre-monsoon, monsoon, post-monsoon winter. Water temperature is most crucial environmental parameter influencing gonadal maturation breeding. Generalized additive model (GAM) models revealed...
Sperata seenghala is one of the largest freshwater catfish Indian sub-continent.This fish has good market demand as food due to its taste with high nutritional value and for this reason it constitutes an important capture fishery all major rivers reservoirs India, Bangladesh Pakistan.Earlier number works been carried out on feeding habit, reproductive biology, morphology, fishery, captive culture etc, but no such consolidated review report available.With view current work sum up available...
Pangasius pangasius is a catfish species which widely distributed in India, Bangladesh, Pakistan, Myanmar, Malaya-peninsula, Indonesia, Vietnam, Java and Thailand. It popular food fish as having good taste with high protein, mineral fat content its flesh. also game recently has got entry ornamental markets too. very hardy nature; tolerance for temperature, salinity turbidity; but due to over exploitation, habitat degradation, water pollution, destruction of the breeding grounds etc. natural...
To get success in culture of any fish species, detail knowledge on food and feeding habit that particular species is really essential. Except the work Piska et al. (1991) no such till date has been performed Amblypharyngodon mola agro-climatic context India. So present study to information this species. Gastro-Somatic-Index, Relative Length Gut, Gut Fullness & Feeding Intensity Content Analysis have studied. Results revealed as herbivorous phytoplankton basic group for species; chlorophyceae...
Pabda (Ompok bimaculatus) is a freshwater catfish, largely available in Asian countries, especially Bangladesh, India, Pakistan and Nepal. This fish highly valued for its fabulous taste high nutritional value very popular as rich source of proteins, omega-3 omega-6 fatty acids, vitamins mineral growing children, pregnant females elders. We performed de-novo sequencing Ompok bimaculatus using hybrid approach present here draft assembly this species the first time.The genome (Fig. 1: Table 1,...
Ornamental fishes are the most popular pet throughout world and high demand for these has made them an important component of fish trade. India contributes a very meager percentage to ornamental trade; but considering ichthyofaunal diversity it potential compete with world’s leading producers in near future. Sundarban Biosphere Reserve abundant waterbodies rich diversity. Although some research been carried out on resources Sundarban; detailed documentation freshwater indigenous this region...
