Estimating the economic income and social contributions derived from the South African west coast rock lobster fishery
The west coast rock lobster Jasus lalandii fishery is South Africa’s third-most-valuable fishery, although the stock is currently estimated at <2% of its pristine biomass. Recent ecologically necessary reductions in the total allowable catch (TAC) had negative economic impacts on stakeholders; however, these have not been quantified as current research into the socio-economic aspects of this fishery is limited. This study explored trends in the net seasonal income and employment opportunities of the fishery in the seasons 2016/17–2018/19 for its different sectors and representative individuals, by analysing records from the government authority and data collected from stakeholders in this fishery through interviews (n = 30) and surveys (n = 19). The results indicate that though the fishery was profitable over the three seasons, with the estimated contribution to gross national income ranging from R453 185 000 (US$33 302 714) in 2018/19 to R564 721 000 (US$41 499 039) in 2017/18, the decreasing quotas had a disproportionate negative effect on some of the representative individuals examined within the different sectors. These worrying economic trends for the different stakeholders indicate that, for effective resource recovery and equitable distribution of fishing opportunities, the socio-economic context of the fishery must be studied more extensively and must be included more directly in management decisions.
期刊介绍:
The African (formerly South African) Journal of Marine Science provides an international forum for the publication of original scientific contributions or critical reviews, involving oceanic, shelf or estuarine waters, inclusive of oceanography, studies of organisms and their habitats, and aquaculture. Papers on the conservation and management of living resources, relevant social science and governance, or new techniques, are all welcomed, as are those that integrate different disciplines. Priority will be given to rigorous, question-driven research, rather than descriptive research. Contributions from African waters, including the Southern Ocean, are particularly encouraged, although not to the exclusion of those from elsewhere that have relevance to the African context. Submissions may take the form of a paper or a short communication. The journal aims to achieve a balanced representation of subject areas but also publishes proceedings of symposia in dedicated issues, as well as guest-edited suites on thematic topics in regular issues.
