Abundant reports on stunted growth in fishes following pesticides exposure are available; however, mechanism underlying it is rarely studied. Since hormones are well known to play vital role in regulation of metabolic activities and general body growth, present study was conducted to investigate the effects of malathion (an organophosphorous pesticide) on metabolic hormones, responsible for pro...

For the purpose of cytological studies and work out the correlations among the teleost fish species, some 5 fish species are selected viz Notopterus notopterus, Labeo rohita, Tilapia mossambica, Clarias batrachus, and Channa gachua. The observations regarding hematology are made from peripheral blood by traditional staining method while histological and cytological studies are done from the sec...

Abstract Walking catfish Clarias batrachus is a freshwaterr fish that has high economic value. Currently, the culture of this local been initiated in Indonesia, but breeding technology not well developed. Therefore, study aims to explore type natural extender for sperm preservation C. so it can support development its technology, especially remote areas. The research was conducted at Hatchery L...

1. Effects of endosulfan, malathion and carbaryl on circulating T4, T3 and T3/T4 ratio in the freshwater catfish, C. batrachus have been studied during reproductively active phases, i.e. vitellogenic and post-vitellogenic phases of its annual reproductive cycle. 2. Endosulfan provoked a significant increase in T4 and a decrease in T3 as well as the T3/T4 ratio. 3. Malathion decreased T3 and T3/...

This investigation was aimed to find out appropriate strategy against antibiotic resistant bacterial fish pathogen, F. columnare. This pathogen was found persistently associated with fishes causing columnaris disease and ensuing mass mortality in hatchery and culture system of Sub - Himalayan region. Nine lytic F. columnare phages (FCP1 - FCP9) specific to its fifteen isolates were isolated fro...
