haemato-biochemical studies in rainbow trout infected with saprolegnia were carried out under temperate climatic conditions of kashmir valley to find out the variation in blood parameters. the trial was carried out on 405 cultured rainbow trout fish ranging in length from 47.8 to 69.8 cm and in weight from 1300 to 1920 g. the same experiment was carried out on 2,70000.00 trout fish eggs from no...

From the 1970s to 1990s, more stringent air quality regulations were implemented across North America and Europe to reduce chemical emissions that contribute to acid rain. Surface water pH slowly increased during the following decades, but biological recovery lagged behind chemical recovery. Fortunately, this situation is changing. In the past few years, northeastern US fish populations have be...

—Dams provide many benefits to society, yet they have profound impacts on aquatic ecosystems. In addition to blocking fish migration, small surface-release dams on coldwater streams generally increase water temperature below the dam. The goal of this study was to evaluate how small, surface-release dams affect fish communities, separating the total effect into components related to fragmentatio...

Haemato-biochemical studies in rainbow trout infected with Saprolegnia were carried out under temperate climatic conditions of Kashmir valley to find out the variation in blood parameters.

Fish fauna of small coldwater streams of North America typically include trout and salmon, sculpins, minnow, sticklebacks, suckers, or lampreys (Hocutt and Wiley 1986). Standard sampling protocols provided herein apply primarily for trout and salmon because of their sport and commercial values (Johnson et al. 2007). As interest in nonsalmonid species grows, further development of sampling metho...

Reducing the dependency of aquaculture on fishmeal and other important fish feed ingredients is key for sustainable development industry. One major bottlenecks in expansion coldwater culture Kashmir valley availability quality at low cost. The local farmers are mostly dependent either outside J & K or State Fisheries Department K. also procures from which results high costs increased cost p...

Over the last 10 years or so, infections caused by bacteria belonging to a particular branch of the genus Francisella have become increasingly recognised in farmed fish and molluscs worldwide. While the increasing incidence of diagnoses may in part be due to the development and widespread availability of molecular detection techniques, the domestication of new organisms has undoubtedly instigat...

An attenuated strain of Flavobacterium psychrophilum (CSF259-93B.17) has shown potential as a vaccine for prevention of bacterial coldwater disease (BCWD) in rainbow trout, Oncorhynchus mykiss (Walbaum). Because BCWD outbreaks can result in high mortality in other salmonid species, specifically coho salmon, Oncorhynchus kisutch (Walbaum), the live-attenuated strain was tested as a vaccine in th...
