The effect of cypermethrin pesticide on juvenile rohu (Labeo rohita) was determined in captive condition. Live and healthy (average initial weight 21g) were exposed to five concentrations Cypermethrin 0.63, 0.13, 0.025, 0.005, 0.001 ppm one control group (no pesticide) with two replications for each treatment. mean temperature pH the experimental tanks 27.53±0.41ºC 7.22±0.013 ppt, respectively....

use of different pesticides in the agriculture sector, in order to boost crop yield within a short time period and low labor, has been tremendously increased since the last decade. pesticide use has elevated crop yield but has produced a number of pronounced problems regarding environmental and health safety. the continuously deteriorating toxicological effects of these pesticides are not only ...

dimethoate (organophosphate insecticide) and lambda-cyhalothrin (synthetic pyrithroid) aretwo frequently used pesticides due to their high effectiveness and rapid breakdown into environmentally safeproducts. the aim of this present study was to assess and compare the acute toxicity of dimethoate(rogor30%ec) and lambda-cyhalothrin (5%ec) on labeo rohita (hamilton). acute toxicity bioassay wascar...

the disposition and cellular organization of the endocrine pancreas were studied in three species of freshwater teleosts viz., labeo bata (hamilton, 1822), sperata aor (hamilton, 1822) and chitala chitala (hamilton, 1822) using histological techniques. in l. bata, the endocrine pancreas tissues were mainly distributed in the adipose tissue among the intestinal coils and adjacent to extrahepatic...

Naidinae (former Naididae) is a group of small aquatic clitellate annelids, common worldwide. In this study, we evaluated the phylogenetic status of Naidinae, and examined the phylogenetic relationships within the group. Sequence data from two mitochondrial genes (12S rDNA and 16S rDNA), and one nuclear gene (18S rDNA), were used. Sequences were obtained from 27 naidine species, 24 species from...

The present study investigated the use of fermented Prosopis juliflora pods (PJP) as a carbohydrate source, alternative to rice bran (RB), and a PJP based diet formulation supplemented with probiotics Lactobacillus acidophilus (LA), Lactobacillus bulgaricus 009 (LB) and Streptococcus thermophilus (ST) on the growth of Labeo rohita (rohu) fingerlings. The diets were isonitrogenous (39%) and isoe...

Labeo rohita, Gibelion catla, Cirrhinus mrigala, Ctenopharyngodon idella and Hypophthalmichthys molitrix were grown together for 365 days in triplicate ponds. Six iso-caloric feeds having varying protein levels i.e. 22, 24, 26, 28, 30 and 32% were prepared and supplemented to fish at 2% fish weight daily. Significantly, higher final average weight (793 ± 197 g) and total length gain (398 ± 40 m...

In India, more than 104 species of Myxobolus have so far been reported infecting freshwater as well as marine fishes. The study focuses on the description of a new myxosporean species, Myxobolus sp.n PKB 2014 from the gill lamellae of an Indian major carp Labeo rohita. The species have been described on the basis of morphological characterization of the spores, tissue architecture and 18S rDNA ...
