CADMIUM TOXICITY STUDIES AND THE EFFECT OF SEVERAL BIO FEEDS IN Labeo rohita (HAMILTON 1822) |  UTTAR PRADESH JOURNAL OF ZOOLOGY

The purpose of this study was to compare and contrast the proximate analysis, AST, ALT, LDH, and SDH levels in Labeo rohita gill, muscle, liver, and kidney. This is due to the great nutritional value of this fish as a source of protein in developing countries. The proximate analysis of L. rohita gathered from various locations in Melarungunam, Cudalore district, Tamil Nadu discovered that hatchery L. rohita had the highest protein (19.97%) and ash (1.76%) contents, while fat (0.84%), carbohydrate (5.39%), and dry matter (24.11%) contents. Labio rohita is a genus of plants. The fish morphology had the highest moisture content (81.42 percent ). During the enzymatic examination, the highest levels of peroxidase and – amylase activity were detected. The liver contained the most Cd metals, followed by the kidney, muscle, and gills in that order. When compared to other fish, fish treated with rice bran and tapioca powder grew the fastest.

EXPERIMENTAL EVALUATION OF DIETS FOR CULTURE OF A POTENTIAL LIVE FEED, Euplotes Sp. (PROTOZOA, CILIOPHORA) | UTTAR PRADESH JOURNAL OF ZOOLOGY

Ciliate protozoans such as Euplotes which are seen among the mass cultures of rotifers have the potential as a live feed for larvae and juveniles of the aquaculture species in hatchery operations. Free living ciliates are potential natural food of many fish larvae because of their smaller size. To obtain the culture of Euplotes sp., four diets were tested 1) Microalgae, Nannochloropsis oculata, 2) Isochrysis galbana, 3) Equal proportion of N. oculata and I. galbana and 4) Baker’s yeast (Saccharomyces cerevisiae). The ciliates were inoculated at a concentration of 50 cells mL-1. On day 5, Euplotes density reached highest in the groups fed the baker’s yeast (14600.00 ± 409.88 cells mL-1) in comparison with the other three media N. oculata (933.3 ± 659.29 cells mL-1 ); I. galbana + N. oculata (966.67 ± 806.64 cells mL-1 ) and I. galbana (333.33 ± 103.28 cells mL-1 ). Six days culture is crucial because most of the marine fish larvae start their feeding by 5-7 days of post hatching. It was observed from the results that Baker’s yeast is highly significant (P<0.01) diet of Euplotes sp. in mass culture.
