Abstract South Africa produces both marine and freshwater aquaculture species, with a combined production output of 5418 tons of food fish in 2015. Key aquaculture species reportedly cultured include four marine species – abalone, dusky kob, mussels and oysters and seven freshwater species – tilapia, trout, catfish, marron crayfish, carp, koi‐carp and ornamental species. The study aims to quantitatively assess the SWOT factors (Strengths, Weaknesses, Opportunities and Threats) of major aquaculture species of South Africa to determine their aquaculture development and market potential. Key food fish species – abalone, dusky kob, mussel, oyster, salmon, trout, tilapia, catfish and marron crayfish, were selected and subjected to qualitative and quantitative SWOT analyses by adapting the quantified SWOT analytical method coupled with the multi‐attribute decision‐making method MADM (SWOT‐MADM). Trout and tilapia are positioned in quadrant I, showing a combination of competitive strengths and market opportunities. Abalone, oyster and marron crayfish are situated in quadrant II; thus, they possess market opportunities but weak in competitive strengths as aquaculture species. Salmon and dusky kob are positioned in quadrant III; both species are weak in competitive strengths and faced with more threat factors rather than market opportunities. Mussel and catfish are in quadrant IV; both species thus have competitive strengths but are facing more threats than opportunities. Catfish recorded the highest competitive strengths due to internal assessment factors such as low FCR, ability to tolerate very high stocking density, rapid growth rate, high survival rate, hardiness and versatility of production systems and locations. Abalone and marron crayfish, on the other hand, both exhibited more market opportunities compared to other key aquaculture species due to external assessment factors like high pricing and good financial indicators. The study is expected to add to the existing body of knowledge and in guiding aquaculture industry stakeholders to make informed decisions with regards to the feasibility of aquaculture species in South Africa.

This study reviews the development and conventional qualitative analysis of aquaculture in Africa, specifically by reviewing the aquaculture sector of key players (Egypt, Nigeria and Uganda) as a reference for South Africa; an aspiring key aquaculture player in Africa based on the launch of Operation Phakisa—South African version of the blue economy initiative. The key players were identified based on current annual production output and critical success factors, thus used as a benchmark for South Africa. Qualitative factors reviewed are critical success factors of the aquaculture sector of the selected countries that are widely germane to aquaculture development. These factors include production outputs (tons) and value ($); cultured species; prevalent aquaculture production systems; types of aquaculture, i.e., freshwater and mariculture; aquaculture development challenges related to fish seed, fish feed, land and water availability; aquaculture market and trade and provision of enabling environment through policies and frameworks. These factors were qualitatively reviewed and analyzed in ranking the aquaculture operations of the key players and South Africa to elucidate the critical success factors and challenges.
