BACKGROUND From 2001-2003 monodon slow growth syndrome (MSGS) caused severe economic losses for Thai shrimp farmers who cultivated the native, giant tiger shrimp, and this led them to adopt exotic stocks of the domesticated whiteleg shrimp as the species of cultivation choice, despite the higher value of giant tiger shrimp. In 2008, newly discovered Laem-Singh virus (LSNV) was proposed as a nec...

Seafood is the main source of dietary mercury (Hg) exposure and it can be affected by species, origin, tissue, processing. The objective this study was to investigate total Hg in shrimp mussels from retail market, compare body tissue distribution cooking time, estimate exposure. A 126 samples (whiteleg Atlantic seabob South American mussel) were analyzed. Total quantified combustion atomic abso...

The effects of single and combined use of two different probiotic bacterial species, Bacillus licheniformis and Lactobacillus rhamnosus on growth performance of Pacific white shrimp Litopenaeus vannamei was evaluated. Shrimp were treated with probiotics in entire crop duration with different test diets. Twelve culture ponds were divided into four groups of each three, Control (CP) without probi...

Prawn, shrimp and crabs sold in Japan are mostly imported from overseas. Detection of irradiated crustaceans is very important for quality assurance. In this study, we used ESR to detect radiation-induced radicals after irradiation of prawn, shrimp and crabs of major species. No radiation-induced radicals were detected in prawn (black tiger prawn) or shrimp (white leg shrimp). Radiation-induced...

The co-culture of juvenile sea cucumber Holothuria scabra (Jaeger), or 'sandfish', with juvenile blue shrimp Litopenaeus stylirostris (Stimpson) was tested by growing groups in co-culture and monoculture for 3 weeks in tanks with enriched sand substratum. Feed was supplied on trays, accessible only to shrimp. Survival of shrimp and sandfish was high in all treatments (73–100%). Growth of shrimp...

Two epizootics of cultured shrimp occurred in India in 1994. The first case of mass mortalities of tiger shrimp Penaeus monodon in July 1994 was very similar to that caused by yellowhead virus (YHV) infection with regard to gross clinical signs, host species and size of shrimp affected, but it was histologically atypical. Very interestingly, intranuclear inclusions typical of a white spot syndr...

Litopenaeus vannamei, which is the most common shrimp species cultivated in the northeast of Brazil, is very susceptible to microbial diseases, and this consequently affects productivity. There are reports of bacteria, viruses and protozoa in these shrimp, but not fungi. This study aims to isolate and identify fungi present in shrimp Litopenaeus vannamei, and in their nursery waters, at two bre...

The importance of sympatric speciation remains controversial. An empirical observation frequently offered in its support is the occurrence of sister taxa living in sympatry but using different resources. To examine the possibility of sympatric differentiation in producing such cases, I measured genetic, behavioral, and demographic differentiation between populations of the tropical sponge-dwell...
