Toxicity of the herbicides like 2, 4-D NA salt, glyphosate and paraquat were tested, fish was investigated in laboratory and toxicity tested with common carp. Median lethal concentrations were determined in acute tests. The 96 h LC50 value was 100, 86 and 26 mg/L were tested. The experiment was laid out in a randomized block design with four replications. Screening of different herbicides was t...

Rohu is a leading candidate species for freshwater aquaculture in South-East Asia. Unlike common carp the monsoon breeding habit of rohu restricts its seed production beyond season indicating strong genetic control over spawning. Genetic information is limited in this regard. The problem is exacerbated by the lack of genomic-resources. We identified 182 reproduction-related genes previously by ...

A 12-week laboratory feeding trial was performed to evaluate the efficacy of two different algae based value added feeds (one containing Spirulina platensis and Enteromorpha intestinalis and the other with Phormidium valderianum and Catenella repens) against conventional (rice bran and mustard oil cake taken in 2:1 ratio, used as control) for fingerlings of Indian major carp, Rohu (Labeo rohita...

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 ...

An experiment was carried out from May to September, 2018 determine the suitable species combination of two indigenous fish Pabda (Ompok pabda) and Gulsha (Mystus cavasius) with Rohu in farmer’s pond. Three combinations (% total stocking densities) Gulsha: = 60: 40 at T1, 40: 60 T2, 50: 50 T3 were tested. Stocking similar (2964/ha) for all treatments. Similar density (200564/ha) maintained The ...

A simple method has been developed for the isolation of Acid Soluble Collagen (ASC) and Pepsin Digestible Collagen (PDC) from the skin of Albacore tuna (Thunnus alalunga), Dog shark (Scoliodon sorrakowah), and one among Indian Major Carps ie, Rohu (Labeo rohita). Biochemical characterization of the collagen extracted was carried out. On wet weight basis the yields of ASC and PDC from shark skin...

This study was aimed to evaluate the efficiency of three experimental feeds, given to three groups of rohu (Labeo rohita) fingerlings, reared in cemented tanks for 45 days. One group of fishes (control group) was fed with hatchery feed; and growth of this group was compared with the other experimental groups. In all the three experimental groups the protein level was kept below the required lev...

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...
