Vannamei shrimp (Litopenaeus vannamei) is one of the mainstay commodities that can increase country's foreign exchange because it has a fairly high selling value in global market. Several problems aquaculture reduce vaname production such as disease, water quality degradation, and feed conversion values. Biofloc an alternative technology be applied to overcome farming. There are two types biofl...

Background Hurricane Mitch introduced several stressors to both aquacultured and feral shrimp populations. These stressors included influxes of anthropogenic pollutants, ...

The effect of exclusion of individual water-soluble (thiamine, riboflavin, pyridoxine, cyanocobalamin, pantothenic acid, folic acid, niacin, biotin, choline, inositol, ascorbic acid) and fat-soluble vitamins (vit. A, D, K and E) in semi-purified diets on growth and survival of juvenile shrimp, P. monodon was studied in the laboratory for 8 weeks. Diets lacking riboflavin and vitamin K did not a...

Cell free extracts of four strains of Lactic acid bacteria (LAB) viz. Lactobacillus. acidophilus, Streptococcus.cremoris, Lactobacillus bulgaricus –56 and Lactobacillus bulgaricus –57 inhibited growth of Vibrio alginolyticus in nutrient broth. The antagonism of LAB to Vibrio alginolyticus was further confirmed by streak plating wherein suppression of growth of Vibrio was obtained. Juveniles of ...

Several species of butterflyfishes (Chaetodontidae) possess extremely elongate jaws, and feed mostly by probing the benthos and biting off pieces of attached invertebrates. In contrast, Forcipiger longirostris, the longest-jawed chaetodontid, exhibits a novel pattern of prey use, feeding almost exclusively on small caridean shrimp, a mobile and highly elusive prey type that lives within the str...

Many of the current greenhouse based intensive marine shrimp production systems have used photoautotrophic algae systems to control inorganic nitrogen accumulation. A second strategy of nitrogen control used in some indoor intensive recirculating production systems is using large fixed-film bioreactors. This option utilizes chemosynthetic autotrophic bacteria, Ammonia Oxidizing Bacteria (AOB) a...

Abstract This study aims to determine the effect and best dose of Indian Pluchea leaf extract on artificial feed growth performance survival rate Vanname. The sample this was shrimp aged PL 21 obtained from farmers in Pekalongan. employed an experimental method with a completely randomized design (CRD) 4 (four) treatments 3 (three) replications, A (Indian 0 ml/kg feed), B 5 C 10 D 15 feed). add...
