The present study was undertaken to determine the effects of polyunsaturated fatty acids (PUFAs) on enhanced maturation, spawning, embryonic and larval development endangered Gangetic Mystus (Mystus cavasius). Fishes were collected from Brahmaputra River, Mymensingh, Bangladesh stocked in cisterns. Treated group provided supplemental diet enriched with 1% squid extracted lipids as a source PUFA...

Like other organophosphates, dimethoate is an acetylcholinesterase inhibitor which disables cholinesterase, enzyme essential for central nervous system function. Dimethoate insecticide can be used both indoor and outdoor purposes to eliminate a number of insect pests under different condition. Dimethoate, one the most extensively studied pesticides, may induce many significant changes in fishes...

length-weight relationship is the most commonly used analysis which has been used for several purposes in fisheries field among which estimation of weight from length is the most popular one. the present study has been performed to analyze the length-weight relationship of mystus tengara , a freshwater catfish of indian subcontinent. total length and body weight of the studied specimens have be...

Nutrition is the major crucial factor determining potential of cultured fish to exhibit its genetic capability for growth. In this study, impact dietary vitamin E supplementation feed on growth performance, conversion ratio and protein efficiency Gangetic Mystus (Mystus cavasius, Hamilton, 1822) were investigate. Total 150 number young M. cavasius (weight 33.0±10.0 g) used CRD (completely rando...

An experiment on the polyculture of carps with high valued small indigenous fish species (SIS) pabda (Ompok pabda) and gulsha (Mystus cavasius) was carried out in six months culture period to evaluate the production performance of carp with small indigenous fish pabda (Ompok pabda) and gulsha (Mystus cavasius) in the on-farm condition. Three stocking densities of pabda and gulsha were tested, k...

studies on reproductive biology are essential to assess culture potential of a fish species. mystus tengara is a popular food fish as well as preferred as an ornamental fish in west bengal. till date detailed report on reproductive biology of this fish species in the agro-climatic context of west bengal is lacking. therefore, the present work was aimed to study the detailed reproductive biology...

By employing the technique of induced ovulation for artificial fertilization, inter-specific hybrids between the threatened catfish species (Mystus cavasius x M. seenghala) were produced. Fertilization, hatching and survival were significantly different between control and hybrids. The hatching time of the hybrid was significantly lower than that of the control. The average performance viz., ha...

Body flesh of the four fish species (Mystus) namely Mystus gulio, bleekeri, cavasius, and vittatus were collected proximate composition mineral contents (Na, K, Ca, Mg, P, Fe, Zn Cu) analyzed. The highest amount protein (22.2±0.94%) lipid (5.25±0.64%) found in M. gulio. maximum moisture (79.31±1.86%) ash content (1.45±0.14%) observed cavasius where gulio showed lowest (71.5±0.95 %) (1.03±0.06%)...
