<title>Abstract</title> This study investigates the effects of melatonin supplementation on gonadotropin gene expression, vitellogenin (Vtg) antioxidant status, ovarian histology, and reproductive performance in female <italic>Clarias magur</italic>. Four experimental diets were formulated: control (0 mg/kg melatonin), T1 (100 T2 (200 T3 (300 melatonin). Results showed no significant difference weight gain between groups, while decreased notably T3. Gonadosomatic index (GSI) fecundity...

The availability of zinc has been correlated with reproductive performance. To validate the hypothesis, a 60-day feeding trial was conducted to evaluate effect dietary on performance and gonadotropin gene (FSH LH) expression in threatened Clarias magur brooder. Four isonitrogenous (35%) iso-energetic (372.18 ± 1.73 k cal/100 g) diets were prepared acetate as control (100 mg/kg diet normal requirement), T1 (50 diet, low zinc), T2 (200 medium zinc) T3 (300 high zinc). weight gain % specific...

A 60-day experiment was conducted to evaluate the effect of biofloc on growth performance and physiological responses grey mullet (Mugil cephalus). Grey fry (average body weight 0.91 ± 0.01 g) were stocked in treatment (BFT) clear water (CW) control triplicates. reared biofloc-based units attained significantly better (p < 0.05) terms final (FBW) (5.98 0.08 g), specific rate (SGR) (3.15 0.05), percentage gain (PWG) (560.7 18.7) survival (80.00 3.8) with lower feed conversion ratio (FCR)...

An experimental trial was conducted for 90 days to evaluate the effect of different carbon sources viz. yam and potato on growth performance milkfish (Chanos chanos) in biofloc-based system. Milkfish fry (average body weight 0.66 ± 0.01 g) stocked biofloc treatments, yam-based (BFY) potato-based (BFP), clear water (CW) as control triplicates. reared units obtained significantly better (p < 0.05) terms growth, digestive enzyme activity survival when compared control. Among highest average...

Background: An experiment was conducted to study the effect of solid-state fermentation (SSF) cottonseed meal (CSM) with Saccharomyces cerevisiae on anti-nutritional factors and amino acid profile. Methods: A finely ground CSM fermented baker’s yeast for 48 h at room temperature periodic observations pH, moisture. The substrate partially sun-dried nutritional values were observed. Result: After SSF process dry basses, protein content increased from 8.74% 12.67%. Besides increasing value,...

A feeding trial of 45 days was conducted for delineating the effect carotenoids on fillet appearance, antioxidant status and nonspecific immune responses Pangasianodon hypophthalmus fingerlings.Two hundred fifty-two fingerlings were randomly distributed into seven different experimental groups in triplicates.Seven isonitrogenous isolipidic diets prepared with two levels (150 300 mgkg -1 ) astaxanthin (T2 & T3), beta-carotene (T4 T5), canthaxanthin (T6 T7) a control diet (T1) without any...

A 60-day feeding trial was performed to test the nutritional value and utilization possibility of palm kernel meal (PKM) as a feed ingredient for juvenile Labeo rohita. Five iso-nitrogenous diets were prepared with various inclusions PKM which replaced sunflower oil cake de-oiled rice bran namely, control (without PKM), T1 (50 g/kg T2 (100 T3 (150 PKM) T4 (200 PKM). The experiment conducted in 350 L fibre reinforced plastic tanks triplicate each tank stocked twenty-five rohu (7.2 ± 0.01 g)...

The Asian catfish, Clarias batrachus of the family claridae, commonly known as ‘magur’ has high commercial importance in India. Aeromonas veronii been reported an important bacterial pathogen for aquatic animals and humans. Several reports have demonstrated pathogenic effect other species on animal; however farmed C. no definitive data are available about A. infection. In present study, a virulent strain BLB-01was isolated from infected collected freshwater fish farm Balabhadrapuram, East...

Better nutrition in aquaculture is essential for higher growth and improved yields. Enhancing production through the intensification of cultural practices ensures profitability a sustained supply fish protein. However, such shifts emphasis to feed-based culture. Feed cost represents significant operational animal production. In aquaculture, it about 50-60% costs plays vital role determining aquaculture. As meal resources are declining, ingredients these feeds will have be sourced mainly from...

Aquaculture, a reliable source of economic gain and employment generation, mainly stands on formulated fish feed costs. Protein is the essential component animal tissues constitutes about 65-75% tissue dry matter. Therefore, protein considered an nutrient source, providing group nonessential amino acids for both maintenance growth. Feed proteins are expensive, their inclusion in aquaculture diets has significant blow overall And fishmeal (FM) makes up nearly 50% total cost, limited FM...

Aim: To assess the impact of different carbon sources on growth performance grey mullet, Mugil cephalus fry in biofloc based culture system during nursery rearing phase. Methodology: The experimental trial was carried out for 60 days using three sources, cassava, jaggery and barley triplicate following a Completely Randomized Design. nitrogen ratio (C:N) systems were maintained at 15:1. Grey mullet (0.91g) stocked @ 1 10 l-1 fed with pelleted feed (35% crude protein) 4% fish body weight...

Background: Stunting is a process of suppressing growth from unfavourable conditions. The protein supplementation during stunting gives scope to maintain the nutrient reserves fish and its quality. Methods: A feeding trial was conducted for eight months study effect three hetero-nitrogenous diets with 25% (control), 30% (T1) 35% (T2) crude (CP) levels on physio-metabolic responses Chanos chanos fingerlings stunting. Milk mean body weight 11.71±0.18 g were stocked in earthen ponds @ 20 no/m2...
