-------------------------------------------------------ABSTRACT--------------------------------------------------The present study was to evaluate nitrite toxicity in fish gills during long-term exposure of sublethal concentration of sodium nitrite (NaNo2). The effect of nitrite on histopathological parmeters were evaluated exposing Indian freshwater fish, Cirrhinus mrigala to a sublethal conce...

The experiment was conducted in two earthen ponds to investigate the body composition, and fatty acid profile of carps along with growth performance by using rice polish as fish feed with urea and ammonium nitrate fertilization of pond. Silver carp (Hypophthalmichthys molitrix), Rohu (Labeo rohita) and Mori (Cirrhinus mrigala) were stocked in the ratio of 1:2:1 respectively with total number of...

Mrigal or Cirrhinus mrigala (Hamilton 1822) is one of the important aquaculture species in India. During 2017, mrigal contributed 5.7% to production The present study was undertaken describe hatchery-level pre- and post-spawning condition, i.e. weight changes length-weight relationships (LWRs) weight-weight (WWRs) associated with two phases for males females used as broodstock from a commercial...

Myxozoans are an economically important group of microscopic parasites best known for the diseases they cause in commercially important fish hosts. The classification of myxosporeans is generally based on the morphology of their myxospores. Without molecular data, it is very difficult to identify new or existing species. DNA sequence information is therefore, a prerequisite to taxonomic and phy...

A 90 day feeding trial was conducted to assess the efficacy of Medicago sativa plant leaf powder as a supplementary feed ingredient for fish Cirrhinus mrigala. Six experimental diets were formulated by replacing fishmeal from standard diet at proportion 30%, 40% and 50% alfalfa powder. Three them kept raw remaining three subjected hydrothermal processing. The weight gain, specific growth rate, ...

Freshwater fish Cirrhinus mrigala were exposed to lethal concentration (5 mg/L) for 1,2,3,4 days and sublethal concentration (1 mg/L) for 1,7,14,21 days of cypermethrin to examine the enzymes activity, in functionally three different tissues namely, gill, liver and muscle. Activities of Aspartate aminotransferase (AAT), Alanine aminotransferase (AlAT) and Glutamate dehydrogenase (GDH) increased...
