Successes and Challenges of Catfish Farming in the Small-Scale Industry in Southern Africa

Abstract

This chapter summarizes the successes and challenges of catfish farming in the small-scale industry in Southern Africa. Given that capture fisheries have been declining steadily over the years in many countries, aquaculture is generally expected to grow to meet demand. However, catfish production in most Southern African countries is low. This is despite the region having the most suitable temperature for the culture of freshwater fish species. In Southern Africa, catfish farming is one of the most important components of inland aquaculture, and it is mainly dominated by the small-scale sector. Production in the small-scale sector is affected by several constraints, which affect the profitability of the sector. These challenges include, among others, quality of production systems, supply of quality fingerlings, feeds, management of diseases, education and training of farmers, marketing and development of products, access to finance, research capacity, extension services, and, to some extent, regulatory frameworks and policies. The chapter proposes interventions that are needed to improve the production of catfish in Southern Africa. For instance, there is a need for the small-scale sector to move from intensive to advanced culture systems, such as recirculating aquaculture systems and integrated aquaculture systems, such as aquaponics, in order to boost catfish production.

Knowledge of fish farmers on using artificial feed for catfish culture

“…Results showed that farmers' knowledge of using artificial feed for catfish culture was significantly improved by their formal education, indicating that if formal education changes by 1 unit (one number), then knowledge of using artificial feed for catfish production changes by 0.348 units. In order to maintain a catfish farm, such as feed management, education is considered to be essential (Esau et al, 2022) [19] . Both Sumon (2014) [47] and Yeasmin (2013) [53] found similar results.…”
