It apparently spawns upstream of shallow sandbars where the eggs settle and hatch as the water begins to rise, with the fry moving into inundated riparian vegetation where they continue to follow the edge of the water as the flooding increases. The spawning season of rohu generally coincides with the southwest monsoon. 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 … ... Reproduction Maturity Spawning Fecundity Eggs Egg development. Here, we report a full-length cDNA sequence of Labeo rohita (rohu) Dmrt1 of 907 bp length having 798 bp of open reading frame encoding 265 amino acids. Labeo rohita was reared in laboratory condition at different salinities to observe the growth and survival. They are bottom feeders and eat algae and small animals. Similarly, adequate dietary energy ... Labeo rohita commonly known as rohu, is an important fish because of higher growth rate, market values, 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. In the resting phase, spermatogonia exhibit the In the resting phase, spermatogonia exhibit the granular staining; however in the seminiferous lobules, both the diffused and granular reaction was observed. Labeo rohita (Hamilton, 1822) Accepted Name Rohu Animalia > Chordata > Actinopterygii > Cypriniformes > Cyprinidae > Labeo > Labeo rohita (Hamilton, 1822) 0. Has not established in the wild [Welcomme 1988].” FAO (2018) lists Labeo rohita as introduced to Bhutan, Sri Lanka, Laos, Thailand, Former USSR, Philippines, Madagascar, Japan, … large protein family whose function is sexual development and differentiation in vertebrates. Among the cultured carps, rohu (Labeo rohita) and Common carp (Cyprinus carpio) contribute significantly to the Aquaculture production in India. Materials and Methods Animals. 236 putative microsatellites were also found of which 20 loci showed polymorphism. This is perforated by an aperture, the micropyle, through which a sperm enters. Considering the above circumstance the present study was performed to Incorporate of water hyacinth, Eichhornia crassipes meal in aqua-feed and its efficacy on growth performance of roho labeo, Labeo rohita (Hamilton, 1822) reared in cage. Feed on plants. Labeo rohita Picture by Jean-Francois Helias / Fishing Adventures Thailand. Distribution of reproduction-relevant transcripts identified in Labeo rohita. Widely introduced outside its native range for stocking reservoirs and aquaculture. Monsoon dependent breeding restricts its seed production beyond season indicating a strong genetic control about which very limited information is available. Leefomgeving. 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. ovary of Labeo rohita from River Beas or control group. 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. Twenty loci showed polymorphism in 36 unrelated individuals with allele frequency ranging from 2 to 7 per locus. We use cookies to help provide and enhance our service and tailor content and ads. Labeo rohita is commercially important freshwater fish, commonly known as rohu. 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: … Requests and inquiries concerning translation, reproduction and adaptation rights should be addressed to copyright@wcoomd.org. The acute toxicity tests were conducted during certain intervals in various concentrations of Dimethioate. (111):100 pp. Sampling of Rohu (Labeo rohita) fish The Rohu (Labeo rohita) specimens obtained from the fish pond at District Poonch of Jammu and Kashmir state were collected in the month of December 2013, with a cast net and identified by the help of various taxonomic keys [18,19]. Optimal dietary protein levels, therefore, are important to maximize the fish growth. Fertilisation is external. (2015) Construction, De-Novo Assembly and Analysis of Transcriptome for Identification of Reproduction-Related Genes and Pathways from Rohu, Labeo rohita (Hamilton). Labeo is oviparous. Lack of genomic resource prevents study on reproductive issues in monsoon bred rohu. 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. 182 reproductive genes & 20 polymorphic SSRs will be highly useful for this species. The young ones are planktivorous. 3631 unique sequences contained 236 (6.49%) putative microsatellites with the AG (28.16%) repeat as the most frequent motif. Spawning occurs in flooded rivers. Fecundity varies from 226,000 to 2,794,000 depending upon the length and weight of the fish and weight of the ovary. 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. Identification of reproduction-related genes and SSR-markers through expressed sequence tags analysis of a monsoon breeding carp rohu, Labeo rohita (Hamilton). Species Labeo rohita Roho labeo. Till dated, the experimental 3D structures of GHR and GH in L. rohita are not present in the Protein Databank (PDB). Two short threads like structures, the barbels, are present. Among the environmental factors, photoperiod plays an important role in growth and reproduction of fish. infected with E. tarda (3 × 106 CFU/fish), for 24, 48, and 72h. De Rohu (Labeo rohita) is een straalvinnige vis uit de familie van eigenlijke karpers (Cyprinidae) en behoort derhalve tot de orde van karperachtigen (Cypriniformes). Prolonged photoperiod may negatively affect growth and reproductive performances of rohu. De hoogst geregistreerde leeftijd is 10 jaar. The male sheds its seminal fluid on the new-laid eggs.
