A 6-week feeding experiments were carried out to determine the effects of different levels of dietary betaine on growth performance, food efficiency and survival rate of pike perch which has a critical period during transition feeding. Fingerlings of pike perch were fed with live food (treatment A), without betaine added to biomar (treatment B), 1% betaine added to biomar (treatment C...

background: iron, manganese, and aluminum are three abundant metals on earth and their concentrations have increased in aquatic environments as a result of natural and industrial activities. this study was undertaken to report the median acute toxicity (lc50) and accumulation of the sub-lethal concentration (10% 96-h lc50) of iron (fe), manganese (mn) and aluminum (al) in kutum (rutilus kutum) ...

sesame oil cake (ssc) was bio-processed through solid state fermentation (ssf) under optimized conditions by a phytase-producing fish gut bacterium, bacillus subtilis subsp. subtilis (jx292128). ssf significantly reduced anti-nutritional factors (e.g., phytic acid, tannins and trypsin inhibitor) and crude fibre, while enhanced free amino acids, fatty acids and different minerals. phytase product...

The primary focus of this study is to assess the toxicity chemical corexit 9527 28 day old fresh water tilapia guineensis fingerlings. fingerlings was studied in static renewal bioassay glass tank, using tap water. collected from Ikpoba HillRiver, Edo State used access lethal concentrations dispersant 9527. Differential sensitivity test organisms observed.This achieved by predictive application...

The high consumer demand in Indonesia encourages catfish farmers to conduct an intensive culture. A low feed efficiency mainly occurs cultivating Sangkuriang resulting poor growth. This condition might be caused by lysine content, as is essential amino acid that the fish cannot synthesize. present study aimed investigate effect of supplementation on protein digestibility, efficiency, and growth...

In this study, the lethal toxicity, behavioral responses and hematotoxicity of formulated chlorpyrifos on Clarias gariepinus was evaluated. C. gariepinus fingerlings were exposed to 0.2 mg/L, 0.25 mg/L, 0.3 mg/L, 0.35 mg/L and 0.4 mg/L of the active ingredient chlorpyrifos to determine the lethal concentrations and behavioral effects. C. gariepinus juveniles (38.84±7.67g) were then exposed to 0...

Delonix regia is commonly called Flamboyant or flame of the forest. The seeds were fermented, boiled, sundried and then ground into powdered meal. 40% crude protein based test diets containing seed meal D0 = 0%; D15 15%; D20 20% D25 25% inclusion levels respectively prepared. Red tilapia (Oreochromis niloticus) fingerlings 6 weeks old acclimatized for two stocked in 12 hapas at 15 fish per hapa...

Abstract This study was conducted to evaluate the efficiency of isolates probiotic bacteria Lactobacillus acidophilus 4453 and Bifidobacterium bifidum 5144 on performance common carp fingerlings which had initial body weight attained (44±0.69) g. A total 72 fish were used randomly divided into 4 treatments with 3 replicates (6 per replicate). An experimental diet prepared a crude protein (29.14...
