Thailand: The History of Shrimp Farming and the Factors That Led to Its Growth

: 5369

Using traditional extensive techniques in large (30 hectares or more), low-lying coastal paddy fields, the first shrimp farms in Thailand were probably started during the 1930s.  Because of the dependence on natural tidal flow for wild seed and naturally occurring food organisms, yields were usually low (approximately 200 kilograms per hectare per year–kg/ha/yr). Semi-intensive shrimp farming in Thailand started during the early 1970s and was replaced by intensive shrimp farming beginning in 1987.  Penaeus monodon was the favored species because [...]

Feed tray management lowers FCRs, shrimp production costs in Australia

: 2742

Black tiger trials with fewer daily feedings show improved conversion results. In lined, aerated ponds, Penaeus monodon fed four times daily had lower FCRs after one month of a culture cycle. In recent years, shrimp aquaculture costs have increased in every sector. Farmers need to find ways to reduce costs to maintain the profitability of the industry. Currently, one possibility for cost reduction is to manage feed consumption without affecting shrimp growth and total harvest. Growout production costs for raising black tiger [...]

Asia: Research – Review of Shrimp Diseases

: 3866

Abstract: This review summarizes recent information about new and newly emerging diseases of cultured shrimp in Asia and discusses the biosecurity lapses that led to the current shrimp production crisis.  All industry stakeholders must be aware of this situation and of the need for regional and global collaborative efforts to stem this crisis and prevent future development of another. In Asia, several shrimp diseases are new or newly emerged, including acute hepatopancreatic necrosis disease (AHPND), hepatopancreatic microsporidiosis (HPM), hepatopancreatic haplosporidiosis [...]

India’s vannamei shrimp farming: Preparing for a better future

: 3615

The Society of Aquaculture Professionals (SAP) played a vital role in the introduction of Penaeus vannamei in India in 2009. “However, recently several issues are threatening the sustainability of this industry. SAP realised that it needs to intervene and bring these issues to the attention of key players in the industry in India as well as the authorities,” said president S Muthukaruppan. It organised a special session on November 8, 2014 in Chennai. SAP invited four speakers to give their views on [...]

Escape from EMS/AHPND at SGIC

: 3959

How this is achieved is through management of culture systems, biosecurity, avoiding use of chlorine for pond and reservoir water disinfection and thorough clean-up of hatchery. Dr Boonsirm Withyachumnarnkul at Centex Shrimp, Mahidol University said that with widespread destruction of crops with early mortality syndrome (EMS) in vannamei shrimp farming, some farms in Thailand have returned to farming the black tiger shrimp in 2013. The Shrimp Genetic Improvement Center (SGIC), Surat Thani, Thailand has largely escaped being infected with the bacteria causing [...]

India: New disease worries vannamei shrimp farmers

: 3298

After achieving a record production of shrimp, which allowed the value of seafood exports from India to grow by 14 per cent yoy in the nine months ending December 2014, the industry fears that the disease known as RMS (Running Mortality Syndrome) may affect the production of vanamei shrimp in the new fiscal year. The main affected states are Andhra Pradesh and Tamil Nadu, in the southern east coast, which are the major producers of this variety of shrimp, and the top earners in the seafood export [...]

Four reasons why India’s shrimp exports are booming

: 2614

For years it seemed nearly impossible for another country to outpace Thailand’s shrimp exports to the United States, the world’s biggest market for shrimp. Early mortality syndrome (EMS) saw an end to that. The disease, which attacks the shrimp’s hepatopancreas, an organ crucial to digestion, proved to be a major setback for Thailand and other producing nations in Southeast Asia starting in 2009. The stunning downturn in production, estimated at more than 30 percent in the region, opened the door [...]

Vietnam: EMS recovery rate masked by imports?

: 1253

For Bowie Leung, Vietnam manager for Bangkok, Thailand-based frozen seafood supplier Siam Canadian Group, the real story in Vietnam is one of a switch to vannamei from black tiger. As for prices, which have also been firming in Vietnam, Leung said the stocks in the US have been impacting sales, but “luckily the UK and continental Europe is doing ok, so I hope all stock can be digested in Q1”. Prices may rise a bit in April, then the harvest comes in May and June, [...]
