Quantitative SWOT analysis of key aquaculture species in South Africa

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.

Policy issues and options in aquatic food systems: Review of frameworks, tools, and studies

“…As part of their review, Babatunde et al ( 2021a) also conducted a quantitative SWOT analysis of key aquaculture players in Africa, which was used to determine the competitive position of the aquaculture sectors of the compared countries (Egypt, Nigeria, South Africa, and Uganda) as a basis for aquaculture policies and road maps. Another study conducted a quantitative SWOT analysis of key aquaculture species in South Africa (Babatunde et al, 2021b).…”
