Fish culture in Cameroon: Small-scale commercial

New approach provides technical oversight through a small team of researchers and extension agents

Small ponds of less than 500 square meters built in series along valley bottoms are the norm among small-scale fish farmers in Cameroon.

Fish culture has a relatively long history in Cameroon. Beginning with experiments conducted in 1948 by the French colonial administration, its subsequent development is chronologically presented in Table 1. Expanding aquaculture programs now continue to help alleviate poverty and supply food in a country that largely depends on fish for protein.

1960After independence, the government extension effort collapses, and by 1963, most ponds were abandoned. Fish farming as a commercial activity comparable to coffee or cocoa did not benefit from the same level of government support. Competition with capture fisheries in newly constructed hydroelectric dams reduced economic viability of aquaculture.
1968-1976UNDP/FAO regional project increases extension stations to 32. The Foumban station trains more than 150 extension agents. Unfortunately, a financial crisis from the donor agencies prevents project completion. In addition, transfer of the sector from the Forestry Department to the new Ministry of Livestock and Fisheries weakens follow-up activities.
1980-1984USAID develops common carp culture in the western highlands. Peace Corps volunteers remain the main manpower for aquaculture extension until 1998.

1990-2000AGCD (Belgium), Haskonig (Netherlands), and MCAC (France) fund other aquaculture projects. Project remnants still visible, even if sustainable approaches were not developed.

Current status

In 2000, about 5,000 ponds belonging to some 3,000 farmers produced about 250 tons of fish, mostly tilapia. The usual practice involves monoculture of Nile tilapia in marginally fertilized or fed small ponds of 100-800 m2. The average extrapolated production is about 1,200 kilograms per hectare per year. 

A recent survey in the western and central provinces revealed that very few farmers were completely satisfied with aquaculture. All desired to produce more and larger fish, but the technical information upon which they rely produces approximately 80 percent small-sized tilapia, which are difficult to sell. However, this level of production remains sufficient to sustain farmer interest in aquaculture.

Advancing technology

Technologies featured in recent projects focused on the use of improved pond designs, polyculture of Nile tilapia fingerlings with African catfish, and manuring plus feeding with locally available materials. In some projects, production has been temporarily increased up to sixfold, indicating that improved yields are possible.

Typically, credit or subsidized inputs were made available to farmers. However, most participants remained at or below the level of technology promoted by the projects and generally failed to continually improve their production or pass it on to fellow farmers.

The main reason for the lack of expansion of improved techniques seems to be that the cost:benefit ratio of the technology promoted was unfavorable within the context of the whole farming system. Farmers are sufficiently clever not to decline offers of free inputs or fingerlings, and often show keen interest as long as external support exists. Unfortunately, such inputs to commercial fish-farming systems will never be economically sustainable.

Changing environment

Dr. Benedicta Oben of the University of Buea is one of the researchers working directly with farmers groups to improve Cameroonian aquaculture from the ground up.

Due to recent changes in Cameroon’s laws of association, thousands of farmers groups – including a number of fish farmers – have organized to better defend their common interests. Hundreds of national nongovernmental organizations have been created to serve as a transition between international donors who brought in new money to directly support these groups.

Fish farming is one activity that benefited from this new environment. One key reason for this is that nearly 49 percent of the animal protein consumed in Cameroon consists of fish. This is especially true for the poor.

After a 50 percent devaluation of the Central African franc in 1994, the market availability of fish decreased from 50,000 tons in 1993 to 45,000 tons in 1995, with a subsequent rise in prices. Population further rose and associated fish demand continuously increased to 78,000 tons in 1999. Fish prices now remain at U.S. $2.00 per kilogram, about 40 percent higher than before the devaluation.

New opportunities

This market situation created new opportunities for small-scale farmers to get into fish production on a commercial basis. To support the efforts of these investors, a new approach to research and extension is being tested by the International Center for Living Aquatic Resources Management (ICLARM) and the Institut de Recherche Agricole pour le Développment de Cameroun (IRAD), with financial assistance from the United Kingdom’s Department for International Development.

This approach provides technical oversight through a small team of researchers and extension agents who work in close collaboration with farmers. There are no subsidies or other material inputs. Economic analysis of the farming systems that are evolving through the course of this project has shown internal rates of return in excess of 34 percent.

The number of farmers involved in this project rapidly expanded from 100 in September 2000 to nearly 400 in October. Under pressure from farmers who demand better technology and politicians who hope aquaculture can meet national food security targets, the project is further expanding through the establishment of a network of local scientists, extension agents, and nongovernmental organizations.
