A Model for Self-Sustaining Litopenaeus Vannamei Farm Alternatives

Microbiota from Litopenaeus vannamei: digestive tract microbial community of Pacific white shrimp (Litopenaeus vannamei)

Bacteria capable of producing different extracellular enzymes of potential relevance in digestive processes were isolated from the stomach, hepatopancreas and intestine of Pacific white shrimp Litopenaeus vannamei. A total of 64 strains with proteolytic activity were isolated and grouped into 16 clusters based on morphological characteristics: 4 groups were isolated from the intestine; 5 from t...

Suitability studies of inland well waters for Litopenaeus vannamei culture

The inland farming of penaeid shrimp in low-salinity waters is now de facto in many regions of the world, yet there is little information pertaining to the suitability of waters with various ionic compositions for shrimp culture. In the present study, short-term (48 h) survival of Pacific white shrimp, Litopenaeus vannamei postlarvae (PL), and long-term (4 weeks) growth and survival of juvenile...

Histopathological observation of black gill disease in shrimp farm, Litopenaeus vannamei, in Boushehr province, Iran

The aim of this study was evaluate tissue lesions caused by black gill disease and its causes in 85-80 days old Litopenaeus vannamei with an average weight of 13-15 g located in the Delvar shrimp rearing site from Bushehr province. Primary and secondary gill lamella was necrosis, central axis were not arranged and gill lamella swelling, epithelial cell necrosis along with karyorrhexis and pykno...

Enhanced Cellular Immunity in Shrimp (Litopenaeus vannamei) after ‘Vaccination’

It has long been viewed that invertebrates rely exclusively upon a wide variety of innate mechanisms for protection from disease and parasite invasion and lack any specific acquired immune mechanisms comparable to those of vertebrates. Recent findings, however, suggest certain invertebrates may be able to mount some form of specific immunity, termed 'specific immune priming', although the mecha...
