Does Dietary Sodium Alginate with Low Molecular Weight Affect Growth, Antioxidant System, and Haemolymph Parameters and Alleviate Cadmium Stress in Whiteleg Shrimp (Litopenaeus vannamei)?

Probiotics in Larvae and Juvenile Whiteleg Shrimp Litopenaeus vannamei

Carbohydrate Moieties and Cytoenzymatic Characterization of Hemocytes in Whiteleg Shrimp Litopenaeus vannamei

Hemocytes represent one of the most important defense mechanisms against foreign material in Crustacea and are also involved in a variety of other physiological responses. Fluorescent lectin-binding assays and cytochemical reactions were used to identify specificity and distribution of carbohydrate moieties and presence of several hydrolytic enzymes, in hemocytes of whiteleg shrimp Litopenaeus ...

The effect of different levels of dietary niacin and carbohydrate on growth performance, carcass composition and heamolymph biochemical parameters of juvenile whiteleg shrimp (Litopenaeus vannamei)

In this study, the effect of experimental diets containing different levels of carbohydrate and niacin on growth indices, carcass composition and heamolymph biochemical parameters of juvenile whiteleg shrimp (Litopenaeus vannamei) were investigated for 45 days. Shrimp with mean initial weight of 5±0.33 g were reared in 300 liter tanks with 8 treatments. Feeding was performed 4 times a day using...

Dietary administration of sodium alginate enhances the immune ability of white shrimp Litopenaeus vannamei and its resistance against Vibrio alginolyticus.

Haemocyte count, phenoloxidase activity, respiratory burst (release of superoxide anion), superoxide dismutase (SOD) activity, glutathione peroxidase (GPX) activity, phagocytic activity and clearance efficiency to the pathogen Vibrio alginolyticus were measured in white shrimp Litopenaeus vannamei juveniles (12.3 +/- 1.2 g) which had been fed diets containing sodium alginate at 0.5, 1.0, 2.0 g ...

Molecular Response of Carbohydrate Metabolism to Dietary Carbohydrate and Acute Low Salinity Stress in Pacific White Shrimp Litopenaeus vannamei

Molecular response of carbohydrate metabolism in Litopenaeus vannamei was evaluated at transcriptional level through quantitative real-time PCR analysis. The mRNA expressions of six genes hexose-6-phosphotransferase, pyruvate kinase, phosphoenolpyruvate carboxykinase, crustacean hyperglycemic hormone, glucose transporter and insulin-like growth factors binding protein in the hepatopancreas, mus...
