A growth study was conducted to determine the dietary threonine requirement of juveniles of the Indian major carp (Cirrhinus mrigala) known as “mrigal”. Diets containing casein and gelatin as sources of intact proteins were supplemented with crystalline amino acids to obtain a crude protein content of 40%. Six diets with different levels of threonine (1.0, 1.3, 1.5, 1.7, 1.9 and 2.1%) were fed ...

Three species of Indian major carp (Labeo rohita,Catla catla,Cirrhinus mrigala) were collected from local fish market and fishing sites of river Brahmaputra for determining the nutritional value,seasonal variation of proximate composition and vitamin A content of these fishes.Results obtained show that there is no much significant seasonal variations in body composition of Indian major carp tho...

The present communication describes three new species of myxosporeans (Myxozoa: Myxosporea: Bivalvulida), Myxobilatus odontamblyopusi sp. n., Myxobolus catmrigalae sp. n. and M. buccoroofus sp. n. from Odontamblyopus rubicundus (HamiltonBuchanan), Catla-Mrigal hybrid carp [male parent fish Catla catla (Hamilton-Buchanan) × female parent fish Cirrhinus mrigala (Hamilton-Buchanan)] and Labeo bata...

The lipid profiles and fatty acid composition of fish eggs (roes) from two common freshwater fish species viz., catla (Catla catla) and mrigal (Cirrhinus mrigala) have been studied. The total lipid of the egg was extracted using chloroform/methanol (2:1, v/v) and was separated into neutral lipids, glycolipids and phospholipids using silica gel column chromatography. The fatty acid composition o...

Investigations on the incidence of myxozoan parasites (Myxozoa: Bivalvulida) in fishes have assumed immense importance in view of severe pathogenicity and mortality caused by these organisms on their hosts. The present communication records three new species of myxosporeans, Myxobolus calcariferum sp. n.; Myxobolus chinsurahensis sp. n. and Myxobolus mrigalhitae sp. n. from different food fishe...

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...

myxosporeans are best known for the diseases they cause in commercially important fish species. identification of myxosporeans at the species-level is mainly based on conventional methods. the 18s rrna gene sequence of morphologically identified myxobolus orissae infecting the gill lamellae of mrigal carp cirrhinus mrigala was characterized in the present study. the plasmodia of m. orissae were...

Ten years ago, very little was known about the genetics of most of the cyprinid species of interest to aquaculture in Asia, for example the Chinese carps, silver carp (Hypophthalmichthys molitrix), bighead carp (Aristichthys nobilis) and grass carp (Ctenopharyngodon idella); Indian major carps, catla (Catla catla), rohu (Labeo rohita) and mrigal (Cirrhinus cirrhosus); and the silver barb (Barbo...

An experiment was conducted to determine the growth performance of two Indian Major Carps Catla catla, and Cirrhinus mrigala fingerlings for period of 40 days. Nine experimental groups fed commercial pellet diet incorporated with three types of nutritional supplements (Gram positive lactobacil probiotic, Parry’s Spirulina and Vitamin C – Ascorbic acid) at different concentrations (2 %, 4 %, & 8...
