The incidence of suspected white spot syndrome virus in semi-intensive and extensive shrimp farms in Bangladesh: implications for management

The study was conducted to assess key factors influencing suspected white spot syndrome virus (WSSV) disease and associated shrimp production and economic performance in three contrasting black tiger shrimp (Penaeus monodon) culture technologies promoted by the United States Agency for International Development funded Shrimp Quality Support Project (SQSP) in Bangladesh.

Improving the productivity of the rice-shrimp system in the South-west coastal region of Bangladesh

The production of wet-season rice followed by dry-season shrimp (Penaeus monodon) is a common farming system in the south-western coastal region of Bangladesh. This chapter summarizes the experiments conducted in the farmers' fields during the rice- and shrimp-growing seasons of 2004, 2005 and 2006, with the aim of improving the total farm productivity of the rice-shrimp system through technological intervention.

Improving aquaculture in post-tsunami Aceh, Indonesia: experiences and lessons in better management and farmer organizations

Coastal aquaculture in Aceh was severely affected by the Asian Tsunami in December 2004. Capacity building among stakeholders was one of the key activities implemented by various agencies during the post-tsunami aquaculture rehabilitation and subsequent development phase. The main objective was improving production efficiencies and farmer incomes. This article describes the process of implementation of the approach and crop outcomes until the end of 2009.

Improvement of traditional shrimp culture in the Mekong Delta.

Improvements to traditional brackishwater shrimp culture in the Mekong Delta, Vietnam are discussed. A technical support program has been implemented based on a so-called improved extensive shrimp culture method, as previously developed and tested by the Artermia and Shrimp Research and Development Center (ASRDC). The program focuses on: 1) the use of hatchery-produced postlarvae (of Penaeus monodon and P. merguinensis) nursed for three to four weeks, and 2) the application of low-cost pond management practices including predator control, supplementary feeding and frequent water renewal.

Heterotrophic marine bacteria as supplementary feed for larval Penaeus monodon

The findings are presented of a study conducted to use autochthonously obtained, nonpathogenic heterotrophic marine bacteria as a substitute feed for microalgae in rearing larval Penaeus monodon. Eleven strains were isolated: Micrococcus (MCC), Staphylococcus, Streptococcus, Bacillus (two strains; BAC-1, BAC-2), Pseudomonas (two strains; PSM-1, PSM-2), Vibrio parahemolyticus, V. fluviatilis, Moraxella (MOR) and Flavobacterium. Six nonhemolytic strains were then chosen for the Penaeus monodon larval feed trials: BAC-1, BAC-2, PSM-1, PSM-2, MCC and MOR.

Health management in marine fish and shrimp hatcheries with special reference to immunostimulants (an overview)

Egyptian Government expresses efforts to provide aquaculture industry with high quality fish and to prevent diseases outbreak. The production of larvae and fry is still unpredictable for some species, owing to the lack of control of the microbiota in the rearing systems. Using conventional approaches such as the use of disinfectants and antimicrobial drugs, have had limited success in the prevention or cure of aquatic disease. Also, use of antibiotics does not constitute a sustainable solution, and may result in microflora imbalance for the larvae.

Growth, mortality and length-weight parameters for some Kuwaiti fish and shrimp

As a (small) contribution toward reestablishing communication between Kuwait-based fishing research and other research conducted elsewhere in the tropics, the growth parameter estimates and the "a" and "b" values of length-weight relationships of 25 fish and three penaeid shrimp species from Kuwait waters are presented, along with the methods used to estimate them. This will hopefully encourage their use in comparative studies of vital statistics offish and shrimp.

A global experiment on tilapia aquaculture: impacts of the Pond Dynamics/Aquaculture CRSP in Rwanda, Honduras, Philippines and Thailand.

The Pond Dynamics/Aquaculture Collaborative Research Support Program (PDA/CRSP) is a global research network to generate basic science that may be used to advance aquaculture development. One of a family of research programs funded by the United States Agency for International Development (USAID), the CRSP focuses on improving the efficiency of aquaculture systems. The PDA/CRSP began work in 1982 in Thailand, and subsequently in the Philippines, Honduras, the US and, until recently, Rwanda.

GHERS: Greater Harvest and Economic Returns from Shrimp

The dynamic shrimp sector in Bangladesh is facing several challenges, particularly low yields and poor quality. Regardless of the high demand for this product, shrimp farming is still characterized as being traditional and having low productivity. The Greater Harvest and Economic Returns from Shrimp (GHERS) has been initiated to narrow the demand and supply gap by increasing farm productivity and vertically integrating the value chain to comply with quality requirement.

Food habits of two sciaenid fish species (Pseudotolithus typus and Pseudotolithus senegalensis) off Cameroon.

Pseudotolithus typus and P. senegalensis (Sciaenidae) sampled off Cameroon Coast, West Africa, have been found to feed mainly on shrimps (Nematoplaemon hastatus and Parapenaeopsis atlantica) and juvenile fish (mostly clupeids). The diet composition is presented and discussed.
