To monitor the genetic variability of L.vannamei shrimp-specie as founder stock and their correspondent first generation (F1), four microsatellite DNA loci species-specific for these animals were used. Data from allelic diversity (size, number and frequency of alleles) and levels of hetrozygozity were obtained as measures of genetic diversity. The protocol used is belonging to the lab, from the ...

A survey was carried out to investigate the prevalence and mean intensities of ectoparasites infestation on the gills and skin mucus of Nile tilapia (Oreochromis niloticus) in some selected fish farms in the Ashanti region of Ghana. Pond water quality was also determined. Oral on-farm interviews on pond management practices were carried out on the farms. The results obtained revealed three types ...

This thesis focuses on the Cod Recovery Plan that was implemented in the Irish Sea in 2004. The plan was constructed within the Common Fisheries Policy, and applied to several European cod stocks that was fished unsustainably. It involved a system of measures including drastic reduction in TACs, closed spawning area, technical conservation measures and effort restriction in the form of “Days at Sea.” ...

The marine protected area (MPA) of Nha Trang Bay, in eastern Vietnam, was created in 2002 as a pilot initiative to enable an adequate management of the fringing reef communities, while providing opportunities for alternative livelihoods to the local fisher populations. A reassessment of the data obtained during the baseline survey performed in 2002 and of an inventory performed in 2005 indicates ...

The consumption of catfish in Vietnam has not grown enough to match their increased production. The objective of this study is to explore the factors that influence the decision process of catfish consumers in Vietnam. The findings provide information for the Vietnamese catfish industry to better attract more domestic consumers to eat catfish. This study seeks to address its objective by examining ...

Export–import relationships are very complex and are regulated by different legal instruments. Incoterms 2000 is one of the most important issues in the international seafood trade. Its use varies depending on business environments, countries and companies involved. The most common factors affecting the choice of delivery terms from Incoterms 2000 are volume/value of the consignment, control over ...

Shrimp world production in the last few years has shown very high growth rates. It is marked by an increasing of production volume, and by shifting from capture to aquaculture fisheries within the production system. This has occurred mostly regarding to the brackish water pond. For some years, the government has had to face hard choices in order to ensure shrimp aquaculture developed sustainable. ...

The tsunami disaster in NAD province has affected and reduced significantly the social and ecological resilience of coastal communities. The ‘huge aid’ and large number of parties involved during fisheries rebuilding process are essential in supporting the rehabilitation of fisheries infrastructure and knowledge transfer in order to improve fishers and fish-farmers capacity in dealing with ecological ...

Natural transformation is one of three mechanisms by which genetic material can be exchanged horizontally between bacteria and the only mechanism that the DNA is actively taken up by the recipient cell. It is also one of the mechanism by which bacteria acquire resistance against antibiotics and thus creating a growing concern worldwide for aquaculture industries. This study uses Acinetobacter baylyi ...
