labeo rohita reproduction

The effects of photoperiod on growth of juveniles and reproductive functions of matured female rohu (Labeo rohita) were analyzed. 9987). Aligarh, India: Department of Zoology, Aligarh Muslim University, 185 pp. Hatching occurs within 2 to 15 hours. These species are presently being increasingly used for the preparation of mince and fillet‐based value added products, with skin forming a major portion of the fishery waste thus generated. In prolonged photoperiod (18L:06D), the Hb and RBC decreased significantly, while WBC and blood glucose level increased significantly during initial days of exposure. Synopsis of biological data on rohu Labeo rohita (Hamilton, 1822). A total of 240 samples of Labeo rohita collected from the twelve (12) different ponds treated with 3 concentrations of n-3 fatty acid (0.3%, 0.6%, and 0.9%), 2 levels of vitamin C (0.75g/Kg and 1.5 g/Kg) and Vitamin E (300 mg/g and 600 mg/g) were investigated for condition factor and length-weight.

The male sheds its seminal fluid on the new-laid eggs. © 2020 The Authors. Effects of egg size on offspring fitness and fecundity of an Indian major carp,Labeo rohita (Ham. Spawning season generally coincides with the southwest monsoon.

In the second experiment, sexually matured females were exposed in the three photoperiod conditions for 30 days and the sampled fishes were sacrificed on 0, 15 and 30 days of exposure to know gonadosomatic index (GSI) and gonadal histology. 120744) ... Reproduction Maturity Spawning Spawning aggregation Fecundity Eggs Egg development. In the Indian subcontinent, rohu (Labeo rohita) is the most preferred species and constitute about 35 % of the Indian major carps production (FAO 2000). Optimal dietary protein levels, therefore, are important to maximize the fish growth. Disclaimer: The Animal Diversity Web is an educational resource written largely by and for college students. In the first experiment, fingerlings (2.39 ± 0.35 g BW, 6.67 ± 1.23 cm TL) were exposed in the three photoperiod conditions for 30 days and sampled fishes were sacrificed on 7, 15 and 30 days of exposure to measure growth parameters (weight gain (g); percent weight gain; specific growth rate, SGR and feed conversion ratio, FCR) and major hemato-biochemical parameters (Hemoglobin, Hb; Red blood cell, RBC; White blood cell, WBC and blood glucose). Several important reproduction-related genes reported here for the first time in L. rohita are zona pellucida sperm-binding protein 3, aquaporin-12, spermine oxidase, sperm associated antigen 7, testis expressed 261, progesterone receptor membrane component, Neuropeptide Y and Pro-opiomelanocortin. The spawning season of rohu generally coincides with the southwest monsoon. Two experiments were conducted each with three different photoperiod treatments, such as 6 h of light and 18 h of dark (06L:18D), 12 h of light and 12 h of dark (12L:12D), and 18 h of light and 6 h of dark (18L:06D), each treatment with three replications. The effect of exposure to sub-lethal concentrations of cypermethrin, a synthetic pyrethroid pesticide, on biochemical parameters of muscle, blood and enzyme activities in brain, liver and kidney of the Indian major carp, Labeo rohita was studied. Induced breeding of Labeo rohita through single application of ovaprim-C at Faisalabad Hatchery, Pakistan Muhammad Naeem1*, Amina Zuberi2, Muhammad Ashraf3, Waqas Ahmad1, Abir Ishtiaq1 and Najam-ul-Hasan1 1Institute of Pure and Applied Biology, … GH protein holds four cysteine residues that generate the functional 3D … 2017 Version 2012 Version Remarks 0304.39 0304.39 ex0304.49 Expansion of the scope of subheading 0304.3 for carp to include other main species, as for example catla (Catla catla) and roho labeo (Labeo rohita). Rohu (Labeo rohita) is a significant freshwater aquaculture species with approximately 1.8 Mt produced annually. This study was conducted to assess the effects of photoperiod on growth of juveniles and reproductive functions of matured female rohu ( Labeo rohita ), a commonly cultured freshwater fish species. A total of 940 reproduction relevant genes were distributed among 184 reproduction related proteins (GO: 0000003), 223 related to hormone activity (GO: 0005179) and receptor binding related proteins (GO: 0005102), 178 receptor activity related proteins (GO: 0004872) and 355 embryonic development related proteins (GO: … Studies on the biology of some important major carps. Gene. Consumer preference for this species has driven researchers to develop genetically improved rohu (Jayanti) for important traits such as growth and disease resistance.

Twenty loci showed polymorphism in 36 unrelated individuals with allele frequency ranging from 2 to 7 per locus. The minimum size at first maturity of male is about 46 cm and in the case of female it is about 51 cm. large protein family whose function is sexual development and differentiation in vertebrates.

Publish in our journal partner Acta Ichthyologica et Piscatoria the results of your primary research on fishes about growth, weight-length relationships, reproduction (maturity, fecundity, spawning), food and diet composition, introductions and range extensions for … Breeds on a seasonal basis in nature, at the onset of the wet season. The male sheds its seminal fluid on the new-laid eggs. Labeo rohita is an important aquaculture species in the Indian subcontinent and the prolonged interaction of GHR and GH can be important in increasing the growth of this species.
