Protecting small-scale farmers: a reality within a globalized economy?

Aquaculture is still the fastest-growing food-producing sector and plays an important role in enhancing global food security and alleviating poverty. Tens of millions of people are engaged in aquaculture production, the majority of whom are small-scale farmers who have limited resources and are faced with difficulties due to increasing globalization and the resultant trade liberalization of aquaculture products. Despite these challenges, small-scale farmers remain innovative and continue to contribute to global aquaculture production.

Production economics of Nile Tilapia (Oreochromis niloticus) pond culture in El-Fayum Governorate, Egypt

Econometric techniques were used to estimate a production function for tilapia pond culture in El-Fayum Governorate, Egypt, utilizing cross-sectional field data. Explanatory variables were feed, initial stocking weight, and pond size. The function was used to examine returns to scale, estimate the productivity of feed and initial stocking weight, and estimate the profit maximizing demand equations for feed and fingerlings. Diminishing returns to scale seem to exist for tilapia pond culture.

A preliminary analysis on the socioeconomic situation of coastal fishing communities in Vietnam

Fish production in Vietnam increased rapidly from 420 000 t in 1981 to 1 130 680 t in 1998. Likewise, there was an expansion in the number of motorized fishing boats from 29 584 units with an average horsepower (HP) of 19.8 boat-1 in 1981 to 71 800 units with an average HP of 26.2 in 1998. In 1995, fish production was valued at VN$2 475 billion (US$0.02 billion at 1 US$ = 11 041 VN$; source: oanda. com).

The potential of nutrient-rich small fish species in aquaculture to improve human nutrition and health

Small fish are a common food and an integral part of the everyday carbohydraterich diets of many population groups in poor countries. These populations also suffer from undernutrition, including micronutrient deficiencies – the hidden hunger. Small fish species, as well as the little oil, vegetables and spices with which they are cooked enhance diet diversity. Small fish are a rich source of animal protein, essential fatty acids, vitamins and minerals.

Multivariate models of tilapia and carp growth as an application of microcomputers in aquaculture research

An examination is made of the applications of microcomputers to aquaculture research, considering in particular data storage and processing and also statistical analysis programmes. Reference is made to development projects with the aim of making use of modern, applied research methods to develop aquaculture technologies applicable for developing countries.

The market for Egyptian farmed fish

Egypt’s aquaculture production (921,585 tonnes in 2010) is by far the largest of any African country. The aquaculture sector, dominated by semi-intensive pond production of tilapia, makes a significant contribution to income, employment creation and food and nutrition security in the country, all of which are national priority areas given low per capita income levels, rising population, worsening food and nutrition security indicators, and official unemployment levels which have remained at around 10% for the last ten years.

Kenya pioneers intensive tank culture of tilapia

Although it appears that the first recorded, scientifically oriented culture of tilapia was conducted in Kenya in 1924,of the current 30,000 ponds with a potential annual production of more than 7,000 tons, only 10% are functional producing 500 tons/annum. Tilapia tank culture at Baobab Farm is described in detail. The economics and prospectsof intensive culture in Kenya are considered.

The Japanese restocking program

In scale of operations, variety of species produced, amount of financial backing, and degree of popular and official support, the Japanese fisheries restocking program (saibai gyogyo) is unique. From its birth in 1962 when the government established two hatcheries on the Seto Inland Sea, it has undergone continuous expansion. By 1982, some 37 coastal prefectures are scheduled to have sea farming centers operating. Seven national centers have been opened and five more are under construction. There are also 11 other semi-government or private hatcheries.
