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

: 5370

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 [...]

India: Central Institute of Brackishwater Aquaculture Makes Shrimp Feed

: 3193

Researchers at the Central Institute of Brackishwater Aquaculture (CIBA) in Chennai, Tamil Nadu, have developed a new feed for India’s multi-billion dollar shrimp farming industry, which currently gets its feeds from foreign companies.  Branded as “Vannamei Plus”, the Indian-made feed is cheaper than the foreign feeds and produces just as much shrimp per hectare.  Three medium-scale feed mills have already been built to produce the new feed. CIBA director Dr. K.K. Vijayan said that feed represents 60 percent of production [...]

A Brief History of Shrimp Farming in Vietnam

: 4671

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 [...]

Ecuador thrives with low-density, sustainable shrimp farming model

: 3006

White spot devastated Ecuador’s shrimp farming industry more than a decade ago, and recovery has been slow. But today the country’s farmers have found a new formula for success — and it seems to be working. The lowest density shrimp producer in the world Ecuador has, for several years, been taking advantage of its sustainable credentials in the wake of Early Mortality Syndrome’s to sweep of its competitors. The big hole in the shrimp market led the country to increase production by nearly 30 [...]

Biosecurity in Shrimp Farming

: 3850

Biosecurity, as it is being applied to shrimp aquaculture, may be defined as the practice of exclusion of specific pathogens from cultured aquatic stocks in broodstock facilities, hatcheries, and farms, or from entire regions or countries for the purpose of disease prevention (Lightner 2003). Lightner (2003), discussed ways of excluding pathogens from stock (i.e., post larvae and broodstock), especially through the use of quarantine and specific pathogen-free (SPF) certified stocks, and restricting imports of live and frozen shrimp. Excluding vectors and external sources of contamination and [...]

Applications of Probiotics in Aquaculture

: 2815

The need for sustainable aquaculture has promoted research into the use of probiotics on aquatic organisms. The initial interest was focused on their use as growth promoters and to improve the health of animals; however, new areas have been found, such as their effect on reproduction or stress tolerance, although this requires a more scientific development. 4.1. Growth Promoter Probiotics have been used in aquaculture to increase the growth of cultivated species, in reality it is not known whether these products increase the [...]

Use of Probiotics in Aquaculture

: 3804

The growth of aquaculture as an industry has accelerated over the past decades; this has resulted in environmental damages and low productivity of various crops. The need for increased disease resistance, growth of aquatic organisms, and feed efficiency has brought about the use of probiotics in aquaculture practices. The first application of probiotics occurred in 1986, to test their ability to increase growth of hydrobionts (organisms that live in water). Later, probiotics were used to improve water quality and control of bacterial infections. Nowadays, there [...]

Some concepts in probiotic bacteria

: 2389

The term probiotic has been defined as “a mono- or mixed culture of live microorganisms that when applied to animals or man, affect beneficially the host by improving the properties of the indigenous microflora”. Moriarty (1996a, 1998) extended the definition for aquaculture to include the addition of natural bacteria to tanks and ponds in which the animals live. Probiotic bacteria improve the health of shrimp or fish by controlling pathogens and improving water quality by modifying the microbial community composition [...]

Probiotics as Antiviral Agents in Shrimp Aquaculture

: 4145

Shrimp farming is an aquaculture business for the cultivation of marine shrimps or prawns for human consumption and is now considered as a major economic and food production sector as it is an increasingly important source of protein available for human consumption. Intensification of shrimp farming had led to the development of a number of diseases, which resulted in the excessive use of antimicrobial agents, which is finally responsible for many adverse effects. Currently, probiotics are chosen as the best alternatives [...]
