Effect of different protein levels on reproductive performance of snakehead murrel Channa striatus (Bloch 1793)
In this study the effect of different protein levels on reproductive performance of Channa striatus was conducted. Snakehead juveniles (65.5±0.2 g) were randomly distributed into nine homogenous groups of 75 fish each. Three isocaloric experimental diets differing in protein levels were prepared. The experiment lasted for 8 months and gonadosomatic index, absolute fecundity, egg diameter, numbe...
متن کاملToxicity of Arsenic (Sodium Arsenite) to Fresh Water Spotted Snakehead Channa punctatus (Bloch) on Cellular Death and DNA Content
Arsenic is a devastating environmental pollutant that has caused severe pollution of ground water in Bangladesh. In this study, Spotted Snakehead (Channa punctatus, Bloch), a common freshwater fish of Bangladesh was exposed to sodium arsenite (NaAsO ) to evaluate its toxic effects on that fish. Different 2 concentrations of NaAsO ranging from 0.5 mM-2 mM were used in this investigation. When th...
متن کاملDe novo sequencing and comparative analysis of testicular transcriptome from different reproductive phases in freshwater spotted snakehead Channa punctatus
The spotted snakehead Channa punctatus is a seasonally breeding teleost widely distributed in the Indian subcontinent and economically important due to high nutritional value. The declining population of C. punctatus prompted us to focus on genetic regulation of its reproduction. The present study carried out de novo testicular transcriptome sequencing during the four reproductive phases and co...
متن کاملCadmium Induced Oxdative Stress in Heptaocytes of Snakehead Fish Channa Punctatus (bloch.)- a Invitro Study
Present study has been undertaken to assess the toxicity of cadmium in vitro for viability of hepatocytes, lactate dehydrogenase leakage, glutathione and lipid peroxidation in Channa punctatus (Bloch), a freshwater snake head fish. Three concentrations of cadmium as cadmium chloride (0.1μg/ml; 3.0μg/ml and 5.0μg/ml) besides one control has been selected. Observations reveal that except lowest c...
متن کاملEstimation of length-weight relationship and condition factor of spotted snakehead Channa punctata (Bloch) under different feeding regimes
Comparative study was conducted to observe the efficacy of different feeding regimes on growth of Channa punctata. Six iso- proteinous diets were prepared by using different agro industrial by-products. Maximum weight gain was recorded with diet having 66.75% rice bran, 11.50% mustard cake, 23.0% groundnut cake, 5% molasses, 1.5% vitamin-mineral mixture and 0.5% salt with specific growth rate o...
