Nutritive value of cultured white leg shrimp Litopenaeus vannamei

Biochemical assays play a major role in recent years. The biochemical composition is the yardstick to measure and assess the nutritional quality of food sources. In the present study, protein, carbohydrate, lipid, moisture and ash in Litopenaeus vannamei was 35.69, 3.20, 19, 76.2 and 1.2% respectively. Calcium content was maximum (154.5 mg) followed by sodium (67.7 mg) and potassium (56.7 mg). Manganese was...

Effects of rotifer, Brachionus rotundiformis in enhancing some digestive enzyme activities into glucose on somatic growth, RNA/DNA contents and some digestive enzyme activities of olive flounder Paralichthys olivaceus larvae

We investigated the effects of enzyme enhanced rotifer (EER), Brachionus rotundiformis on growth, RNA/DNA contents and digestive enzyme activities in olive flounder Paralichthys olivaceus larvae. Digestive enzyme activities of rotifer were enhanced by putting glucose in culture medium, and then rotifers (NR, rotifer not supplied the glucose during culture, and EER) was supplied to 10 rotifers/ml in...

Effect of clove (Eugenia aromatica) powder anaesthetic on some haematological parameters in hybrid catfish (Heterobranchus bidorsalis ♀ x Clarias gariepinus ♂) juveniles

This study was designed to investigate the efficacy of clove powder as anaesthetic and its effect on some haematological parameters of hybrid (Heterobranchus bidorsalis â™€ x Clarias gariepinus ♂) juveniles. Different concentrations of 80, 90, 100, 110, 120, and 130 mg/L were exposed to 108 healthy fish of mean weight 20.38 ± 3.30 g and total length 14.33 ± 2.50 cm for 30 min at the Fisheries...
