Ecuadorian shrimp farming: A success story

: 10744

Located between Colombia and Peru on the Pacific cost of the South American continent, Ecuador is a small Latin American country, with only 277,000 square kilometers of land and 2,200 km of coastline. Nevertheless, Ecuador is one of the world’s major players in farmed shrimp production, especially if we look at the shrimp production ratios relative to the land surface or to the length of coastline of the considered countries. Shrimp farming in Ecuador started in 1969 with the extensive [...]


Born in Hawaii, SPF broodstock shrimp industry faces globalization

: 7335

For two decades, Hawaii has led the way for Specific Pathogen Free shrimp and the growth of a multibillion-dollar industry The Oceanic Institute in Hawaii, on the shore in the distance, was one of the participating institutions in a USDA-funded consortium to breed specific pathogen free (SPF) broodstock shrimp for a growing aquaculture industry.

Testing an intensive shrimp hatchery system using biofloc technology

: 8462

The hatchery phase is a critical and complex first step in the commercial farming of Pacific white shrimp, and constant attention is required to produce shrimp postlarvae of the best quality possible. The use of biofloc technology (BFT) is increasing in the aquaculture of many commercially-important aquatic species. BFT is used to intensify production and to minimize or prevent the exchange of culture water, with a consequent reduction in potential pathogens and the discharge of nutrient-rich effluents into the environment. The [...]


Asia: Research – Review of Shrimp Diseases

: 8404

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 [...]


The Benefits of Shrimp Nurseries

: 6480

Over the last six years, nursery systems have evolved rapidly in Latin America.  Now, the culture period in nurseries is longer, the biomass is larger and the transfer systems and water control systems (zero exchange) are better.  Feeds and probiotics have also been improved.  The target is to produce stronger postlarvae that have been acclimated to the pond environment.  This results in better survival during the first days of culture and minimizes exposure to disease vectors. Since the causative agent [...]


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

: 9660

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 [...]


India – Shrimp Feed Industry

: 7722

After the introduction of Penaeus vannamei, the shrimp feed business in the country underwent a great change.  New companies entered the feed business and existing feed companies expanded. Now India has nearly 25 aquafeed companies.  The total production of aquafeeds in 2014 was estimated at 1.25 million metric tons of fish and shrimp feed.  Shrimp feed production was approximately 600,000 tons, and fish feed production was 650,000 tons.  If all the smaller feed mills were included in this survey, the total [...]


What do we know about EHP?

: 12214

• Tissue specific for HP unlike most other microsporidians which affect muscle • Transmitted orally between shrimp with no need for an intermediate vector very unusual and very worrisome • Very difficult to visualize with normal histology • Requires practice and patience • Once spores are in ponds very difficult to eradicate HP with EHP spores Control of EHP • Two fold approach to possible control – Broodstock carriers shed spores in feces which contaminate egg and nauplii surfaces. – Farmed animals shed spores into ponds which in [...]


Which solution to reduce production cost of Vietnam farmed shrimp?

: 6997

In recent years, Vietnam shrimp production area have been growing in 2014, brackish water shrimp farming area reached 685,000 ha with an output of 660,000 tonnes, up 4.4% in area and 20.4% in volume compared to 2013. Black tiger shrimp production reached 260,000 tons in 2014 compared to 2013, while production of white leg shrimp was 400,000 tons and increased 45.3%. In 2014, Vietnam shrimp continued positive growth momentum of 2013, accounting for 50% of total seafood export value reached US$ [...]


A Brief History of Shrimp Farming in Vietnam

: 12833

Shrimp News: The March 2015 edition of World Aquaculture, the quarterly magazine of the World Aquaculture Society, contains an excellent article by several Vietnamese researchers (see Source below) on the history and current status of shrimp farming in Vietnam.  Here, I report on the history.  I’ll cover the current status elsewhere on this webpage. With diversification of species, systems and organizational structures—hatchery and farm production of marine shrimp in Vietnam has been growing rapidly for several decades, contributing significantly to [...]
