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...

ABSTRACT: The effect of methods to remove protein content on the properties glucosamine hydrochloride from shells white leg shrimp (Litopenaeus vannamei) and black tiger (Penaeus monodon) was investigated. Chitin obtained by demineralization in 6% HCl for 12h, deproteinization two different (first group soaked 8% NaOH 36h second treated Alcalase enzyme at concentration 0.2% 36h). Two samples we...

The virucidal effect of pH and salinity on Penaeus monodon baculovirus (MBV) was investigated by water borne inoculated methods exposing PL12 Penaeus semisulcatus for 10 hours and observing for 10 days at temperature 28- 30°C. For this purpose, one thousand virus free PL12 of P. semisulcatus were divided into five groups and each group placed in a 10 L plastic basin containing chlorine-trea...

BACKGROUND The microsporidian Enterocytozoon hepatopenaei was first described from Thailand in 2009 in farmed, indigenous giant tiger shrimp Penaeus (Penaeus) monodon. The natural reservoir for the parasite is still unknown. More recently, a microsporidian closely resembling it in morphology and tissue preference was found in Thai-farmed, exotic, whiteleg shrimp Penaeus (Litopenaeus) vannamei e...
