aflatoxins (afs) are one of the most important mycotoxins due to their common occurrence in feedstuffs and feeds that pose a serious threat to humans and animals. although many outbreaks of acute and chronic diseases have been attributed to consumption of aflatoxin-contaminated foods, the most significant effect of aflatoxin is hepatotoxicity in farm animals, especially aflatoxicosis in shrimps...

this study was conducted to evaluate the possibility of white leg shrimp (litopenaeus vannamei) culture twice a year in nayband agro-industry complex in 2010. three earth ponds (0.8 ha) were selected in the farm which had similar conditions in terms of culture system, postlarvae age (pl12) and stocking density (37-38 pl m3). the first period of shrimp culture started from mid april and they wer...

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...

Socio-economic and environmental impacts analysis of shrimp (Paeneus monodon) farming in the gher area of Bagerhat District is an important aspect where shrimp cultivation increased over the years. An investigation was conducted to evaluate the present socio-economic status as well as to investigate the soil and water quality of the study area. This study has been carried out at ten villages in...

samples of water, sediment and shrimp obtained from hatcheries and culture ponds were collected over a period of four months and were analyzed for vibrio parahaemolyticus. samples included the following: two samples of shrimp larva from two hatchery ponds (wlh); 14 samples of water, sediment and shrimp from 14 culture ponds supplied with shrimp larvae from the same hatchery ponds that were obta...

The “greenwater culture” of the tiger shrimp, Penaeus monodon, is an innovative culture technique for the grow-out rearing of shrimps. This culture method involves the use of rearing water of tilapia for the rearing of tiger shrimp in grow-out ponds and or the polyculture of shrimp with tilapia. This culture technique was reported to prevent disease outbreaks attributed to luminescent Vibrio. T...

A study was conducted on culture practices of shrimp at farmers’ level in Bagerhat District. Investigation was based on a sample of 123 shrimp farmers from the seven Thanas (Fakirhat, Mollahat, Sadar, Rampal, Mongla, Chitalmari and Kachua) of the District, 73.17% farmers produced shrimp with white fishes. Farmers (54.47%) started to culture during 2000-2004 in this area. The culture period was ...

There are about 100 penaeid shrimp species in China’s coastal waters, of which a dozen Penaeus spp. and Metapenaeus spp. have commercial value (Liu 1989a). The main species cultured in China are Penaeus chinensis, P. monodon, P. japonicus, P. merguinsis and P. penicillatus. Chinese shrimp farms are distributed along almost 18,000 km of coastline from Hainan Province in the tropics to Liaoning P...

this investigation was conducted to survey the growth and survival rate, weight average, fcr, and harvestable white leg shrimp biomass during 107 days culture in mono and poly culture earth pond system with mullet fish. nine 600 m2 earth ponds  were prepared and stocked with 20 shrimp post larvae in each pond (mean weight 0.007 ±0.001 g) for three treatments (each with three replication). after...
