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...
The Probiotics is “a live microbial feed supplement which beneficially affect the host animal by improving its intestinal microbial balance” (Fuller, 1992). The scientific shrimp culture started during 1980s. There is about 1.2 million hectare of brackish water available for shrimp culture in India. This shrimp culture is carried out by traditional, extensive, semiintensive and intensive method...
It is estimated that approximately 60% of disease losses in shrimp aquaculture have been caused by viral pathogens and 20% by bacterial pathogens. By comparison, losses to fungi and parasites have been relatively small. For bacterial pathogens, Vibrio species are the most important while for viral pathogens importance has changed since 2003 when domesticated and genetically selected stocks of t...
the best method of fish breeding is the isolation of pure lines having high-producing hybrids. the decline in heterosis (dih) resulted from inbreeding, maternal effects, general combining ability (gca) and specific combining ability (sca) on reproductive traits (e.g., egg production, number of hatched egg, and hatchability of pure lines and crosses) of tiger, green, and albino barbie hybrids we...
A submerged biofilter (SBF) with 0.1 m of filter medium was maintained without backwash at four different water temperatures (14°C, 18°C, 22°C and 26°C) in four different recirculating systems stocked with green tiger shrimp (Penaeus semisulcatus). The ammonia removal profile and nitrification performance of the SBF was evaluated at feed loading rates of 2.65 g day at 14°C, 5.52 g day at 18°C, ...
Black tiger shrimp Penaeus monodon is one of the major shrimp species being cultured in Asian countries. Disease outbreaks have resulted in a decline of P. monodon cultivation and severe losses in the shrimp production. To combat harmful microorganisms, shrimp produce diverse classes of antimicrobial peptides (AMPs) as part of their immune defense. In P. monodon, several cDNA sequences of AMPs ...
In Bangladesh, black tiger shrimp (Penaeus monodon; Fabricius, 1798) aquaculture has come to be one of the most important sectors in both the rural and national economies. Likewise, organic shrimp aquaculture has emerged as an alternative farming enterprise for farmers especially in the southwestern districts of Bangladesh. The present study aims to show key performance characteristics of organ...
Integrated Multi-throphic Aquaculture (IMTA) is a system in cultivation that prioritizes balance its maintenance. The IMTA method utilizes feed residues can be utilized by organism from the remaining biota at higher levels of trophic with lower levels. This study aims to analyze biological parameters different densities seaweed and green mussels best stocking for growth survival tiger shrimp. t...
We investigated aquaculture production of Asian tiger shrimp, whiteleg shrimp, giant river prawn, tilapia, and pangasius catfish in Bangladesh, China, Thailand, and Vietnam by using life cycle assessments (LCAs), with the purpose of evaluating the comparative eco-efficiency of producing different aquatic food products. Our starting hypothesis was that different production systems are associated...
