One of the major steps in the innate immune response of shrimp includes the activation of serine proteinases of the pro-phenoloxidase pathway by the prophenoloxidase activation enzyme (PPAF). In this study, the cDNA encoding a serine proteinase homologue (SPH) with prophenoloxidase activating activity of Penaeus monodon (PmPPAF) was cloned and characterized.
South-East Asia has traditionally been the global centre of production of tropical sea cucumbers for Chinese markets. Early research into culture methods took place outside this region, notably in India, the Pacific region and China. However, recent investment in Holothuria scabra (sandfish) culture has led to some significant advances within this region. The Philippines and Vietnam have been at the forefront of recent efforts, with involvement from substantial national programs and local institutions as well as international donors and scientific organisations.
This study aim was to understand the livelihoods of tiger shrimp (Penaeus monodon, Fabricius, 1798) post larvae collectors in the Backkhali river estuary areas under Cox’s Bazar district in Bangladesh during November 2010 to April 2011 where shrimp fry are caught. There are about 130-140 families and about 1000 people are living in the adjacent area. Most of the fry collectors have no land or house. They build house on Government (khas) land near the coast, the housing is mainly with earthen/bamboo or polythen.
Research by the authors examined the impacts of governmental and non-governmental standards on the ability of seafood producers and processors in Vietnam to access export markets. The Vietnamese government plays an important role in the governance of international seafood trade, but importing nations establish food safety standards and NGOs have also become involved. To assure market access, exporters must respond to buyers and certification systems that buyers adopt.
A general form of the yield equation is presented. This is used to investigate the effects of seasonal growth oscillations on estimation of yield per recruit. The results show that these effects will be strongest in short-lived organisms such as penaeid shrimps.
A comparative study of growth performance of giant tiger shrimp, Penaeus monodon from two traditional and two semi-intensive culture systems was conducted from 14th March to 16th July, 2008 in the village Pania under Kaligonj Upazila of Satkhira district in order to observe the following attributes: stocking density, growth, growth rate, survival rate, production, production rate, production cost, net profit, gross profit and water quality parameters.
This paper reviews the coastal fishery resources of Bangladesh emphasizing the coastal environment, capture fisheries and management issues relative to the sector. Bangladesh’s Exclusive Economic Zone (EEZ) covers an area of about 166 000 km2. This area has abundant natural resources such as fish, shrimps, crabs and other marine products. Shrimp and fish trawling is the most important economic activity in this area. The fishery sector makes a significant contribution to the national economy in terms of foreign exchange, income generation and employment.
The Mekong River delta of Vietnam supports a thriving aquaculture industry but is exposed to the impacts of climate change. In particular, sea level rise and attendant increased flooding (both coastal and riverine) and coastal salinity intrusion threaten the long-term viability of this important industry. This working paper summarizes an analysis of the economics of aquaculture adaptation in the delta, focusing on the grow-out of two exported aquaculture species—the freshwater striped catfish and the brackish-water tiger shrimp.
The findings are presented of an investigation conducted to assess the current status of the artisanal shrimp fisheryof Cross River Estuary, Nigeria with respect to catch rates and species composition. Three shrimp species were found to occur regularly in samples taken: Nematopalaemon hastatus, Exhippolysmata hastatoides and Parapenaeopsis atlantica , the former being the dominant species.
Women in India are involved in various facets of shrimp (Penaeus monodon; Penaeus indicus) farming, including pond construction, seed collection, collection of feed materials and preparation of feeds, pond maintenance and post-harvest handling. This study indicates that 40% of laborers involved in shrimp farm construction are women. The various roles of women in shrimp farming are also described.
