Seasonal effects of melatonin on ovary and plasma gonadotropin and vitellogenin levels in intact and pinealectomized catfish, Clarias batrachus (Linn).
Effects of daily administration of melatonin for 15 days were evaluated with respect to ovarian activities and plasma gonadotropin (GtH II) and vitellogenin (Vg) levels in intact (INT) and pinealectomized (Px) female catfish, C. batrachus, during preparatory (April), prespawning (May and June), spawning (July) and post-spawning (September) periods. Px (saline control groups) caused a stimulator...
متن کاملThe seasonal incidence of parasitic helminth infection among the walking catfish, Clarias batrachus of Tripura, India
In the present study, a total of 868 walking catfish, Clarias batrachus, were collected during the period of April, 2012 to March, 2015, to evaluate the prevalence of helminth parasites from different parts of Tripura, Northeast India. Of these, 606 fish were found to be infected with one genus of trematode viz., Astiotrema, two genera of cestode viz., Lytocestus and Djombangia and one genus of...
متن کاملEstimation of Acute Toxicity of Chromium to the Freshwater Catfish Clarias batrachus (Linn.)
Anthropogenic activities has increased the discharge of various concentrations of both essential and nonessential metals into aquatic ecosystems. The present study has been conducted to determine the median lethal concentration of chromium to the freshwater fish Clarias batrachus following standard procedures and was found that 40.56ppm, 38.15ppm, 36.65 ppm and 35.50ppm for 24h, 48h, 72h and 96...
متن کاملControl of melanosome movements in isolated skin melanophores of a catfish Clarias batrachus (Linn.).
Adrenergic and cholinergic receptors have been studied in isolated skin melanophores of a catfish Clarias batrachus. Catecholamines induced a strong aggregatory effect on the melanophores. Melanosome aggregation induced by adrenaline and noradrenaline was partially blocked by alpha adrenergic receptor blockers and a beta receptor blocker. Cholinomimetic drugs aroused a significant dispersion of...
متن کاملChanges in Glycogen Content of Brain in Starving Catfish Clarias batrachus [Linn.]
Glycogen is a multi-branched polysaccharide of glucose that serves as a form of energy storage in animals. The present paper deals with changes in the level of glycogen in Clarias batrachus, which was subjected to prolonged fasting of 40 days. Tissues of brain were selected for the study. Glycogen content was estimated by the calorimetric method of Kemp et al. (1954) as modified by Krishnaswamy...
