Ecuadorian shrimp farming: A success story

: 5041

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 [...]

WWF Research Finds Improved Environmental Performance is Good for Shrimp Aquaculture Business

: 3047

More intensive shrimp farming can yield better environmental and economic results, according to a new study conducted by World Wildlife Fund in Vietnam and Thailand. By producing more shrimp per hectare of land, farmers can increase production to meet growing demand for shrimp without increasing pressure on the region’s natural resources. “Natural resources like land, water, wild fish and energy come with a price tag,” said Aaron McNevin, Ph.D., director of aquaculture for WWF’s Markets and Food program, and lead [...]

Shrimp Pond Waste Management – Approaches

: 4459

Increase in food production from fisheries sector led to introduction of noval technologies and intensive farming methods in shrimp culture that result in increased production of shrimp. Management of water and waste that produced is critical factor that has to be considered. In order to discharge waste water, some improved recirculating systems have been developed. But, the sludge has been neglected and posing a serious problem. So a systematic waste management strategy is needed which include treatment, disposal and [...]

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

: 6380

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 [...]

AQ1’s—Acoustic Feeding System—Update

: 2467

At the World Aquaculture Society Meeting in Las Vegas, Nevada, USA (February 22–26, 2016), I interviewed Attilio Castano, Regis Bador and Ross Dodd—all three very much involved with the development and utilization of the AQ1 System, which records the sounds shrimp make when they feed and then uses those sounds to control and optimize feeding with automatic feeders. Attilio operates a 220-hectare shrimp farm in Ecuador and has been instrumental in the adoption of the AQ1 System in Ecuador, Regis [...]

A Brief History of Shrimp Farming in Vietnam

: 5903

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 [...]

Greenhouse Emissions From Aquaculture

: 2392

Summary: To quantify the carbon dioxide and methane fluxes in tropical earthen ponds, the authors used freshwater prawn farming managed according to different strategies as a model. Ponds with both nighttime aeration and artificial substrates released an average 3.3, 2.0 and 1.5 times more carbon dioxide than traditional ponds or those with aeration or substrates alone, respectively. The absorption of carbon dioxide occurred only in ponds using night aeration. Methane was released in the day and night. The diffusion chamber [...]

India, Tamil Nadu – Big Problems

: 2888

Durai Balasubramanian, secretary of the Pattukottai Shrimp Farmers Association (4,000 members) in the state of Tamil Nadu, reports: There are many reports about the dramatic expansion of shrimp farming in India, but the truth is that farmers in the state of Tamil Nadu have big problems. • In the last year, feed costs have risen 23%, from $1.00 a kilo to $1.31 per kilo. • Over the past two years, seedstock costs have risen 60%. • Farmers have survivals of 80% for the first [...]

Water Quality Parameter Analysis for the Feasibility of Shrimp Culture

: 3695

Muhammad Kasnir et al, Indonesia Moeslim University, Indonesia, carried out physicochemical studies to assess water resource in Mangara Bombang District, South Sulawesi in relation to their potential for shrimp aquaculture use. Introduction Tiger shrimp production in South Sulawesi amounted to about 12599.50 tons in 2007. Nationally, its production was at the fourth ranking after Riau Islands, North Sumatra and West Java [1]. The tiger shrimp production number was the aggregates production in several Regencies which have the coastal area in South Sulawesi Province. One of them is [...]
