Abstract

In this paper, forecasts were made and two-stage deterministic optimization models were designed to maximize annual fish sales revenues and increase the number of jobs on fishing in Angola in the current scenario. Starting from historical data from 2016 to 2022, taking their means and standard deviations, normal distributions were generated up to 2050. If these models were adopted, annual income would reach Kz 260,753,942,425.00 as opposed to the current Kz 246,617,594,646.47 produced with the sale of 5 species of crustaceans, 3 of mollusks, 34 of demersal fishes, 6 of pelagic fishes and 5 of freshwater fishing, resulting in an annual increase in income of around 5.73% and 6,514 new jobs and direct self-employment, of which 328 in industrial fishing, 319 in semi-industrial fishing, 3,355 in maritime artisanal fishing and 2,512 in freshwater artisanal fishing. Of these, 5,071 will be for fishermen and 1,443 for women fish processors. The optimal portfolio of fish sales revenue would be 3% for crustaceans, 1% for mollusks, 34% for demersal Fishes, 54% for pelagic fishes and 8% for fish from freshwater fishing. These results would be excellent for the fishing sector to contribute to achieving the employability goals envisaged by the Angolan government in the medium and long term.
