Improved breeding of Nile Tilapia leads to productivity gains

WorldFish, Malaysia (30 November 2012)
 
Two improved strains of Nile Tilapia that grow 30% faster and heavier than non-improved strains are helping to increase aquaculture productivity and food security in West Africa and Egypt.

Genetic parameters and selection responses were obtained for harvest body weight of blue tilapia (Oreochromis aureus) from data collected over three generations in a selected population. A total of 18 194 records representing 186 sires and 201 dams were used in the analysis. Within generation heritability estimates for harvest body weight ranged from 0.18 to 0.58. When data from more than one generation were included in the analysis, heritability estimates became more stable (0.33–0.40) and it was 0.33 when all data were included in the analysis. The common full-sib effect accounted for 10% of the phenotypic variance in the full data set. Heritability for survival from stocking to harvest was estimated at 0.01 and 0.09 in actual units (fitting an animal model) and in the logit (sire model) scale respectively. The genetic correlation between harvest body weight and survival was 0.22 and not significantly different from zero. The total selection response for harvest body weight over the three generations of selection measured as the difference between least-squares means of selected and control lines was 17.7%. The corresponding figure when response was measured as the difference between mean breeding values of selected and control lines was 19.6%. The average inbreeding coefficient was 0.003 after three generations of selection. These results indicate that there are good prospects for the genetic improvement of harvest body weight in blue tilapia.

Can we afford to adapt? The case of aquaculture in Vietnam

By Caity Peterson
Source: CCAFS Blog

Catfish farmers in Vietnam’s Mekong River Delta are barely scraping by. They operate on the tightest of profit margins – 3% to 5% in a good year – and deal with a highly volatile, boom-and-bust export market.  For an industry that’s already on the brink, could the addition of negative climate change impacts push it over the edge?

Researchers at WorldFish, as part of the project “Investigating the vulnerability of and economics of adapting aquaculture in Vietnam to climate change”, partly funded by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS), have attempted to calculate the costs of adaptation to these impacts, a first for fisheries and aquaculture at the national level.

Partnership Story – Fast-growing fish to reduce poverty in Ghana

In Ghana, the Volta River basin reaches across over half of Ghana’s countryside. Lake Volta, the world’s largest (by surface) man-made lake, is the centerpiece of both the Volta River and the Ghanaian economy, as it provides a source of hydroelectric power as well as vast populations of fish for the locals. With demand for fish booming to support a growing population, meeting supply is often a challenge. Since 1999, the Water Research Institute (WRI) in Ghana has been working with WorldFish to make the Volta basin as productive as it can be through a Nile Tilapia breeding program.

The private sector: partnering for poverty relief and profit

Addressing the problems of poverty and malnutrition in low-income communities is usually the preserve of government agencies and development organizations. However, with demand for fish products soaring worldwide, the small-scale fisheries sector in developing nations represents a potentially lucrative – as well as ethical – opportunity for private sector investors. WorldFish has formed partnerships with a number of private sector partners to create a win–win scenario for business and local communities alike.

Open Day highlights improvements in Egyptian aquaculture

WorldFish hosted an open day on Monday 15th October at its Abbassa research center in Sharkia, Egypt to showcase its latest research and development initiatives, with the support of the Minister of Agriculture and Land Reclamation, Dr. Salah Abdel Mooemin. The Malaysia-based international research organization has had a fisheries and aquaculture research program in Egypt since 1998, and has been a major player in helping aquaculture to grow and become the main source of fish for Egyptian consumers.
