How the pre and post COVID-19 era have shaped system understanding of the socioeconomic impact of small-scale inland fisheries

The current study provided a socioeconomic quantification of small-scale inland fisheries in East Africa using fish market information data for major markets in the pre (2009–2017) and post COVID-19 containment (Jan–May 2022) eras. The socioeconomic status index (SEI) incorporated 6 dimensions: access to fresh fish, access to market, available fish processing (drying) infrastructure, favourable price range, high quantity range traded, and high seasonal profit margins; using three major commercial fishes (Nile perch, Tilapia and Dagaa) and the season (pre and post COVID-19) as the main independent variables. The SEI was calculated using a segmented sociometric scale interval as: ≥ 4.21Very High ≤5.00; ≥3.41 High ≤4.20; ≥2.61 Moderate ≤3.40; ≥1.81 Low ≤2.60; and ≤1.00 Very Low ≤1.80. The socioeconomic quantification was highly dependent on COVID-19 containment periods that reflected very high (pre COVID-19 = 4.67, post COVID-19 = 4.06) impacts on small-scale inland fisheries. This suggested a negative impact of COVID-19 on small-scale inland fisheries attributed to various factors such as disrupted value chains, reduced purchasing power among the customers, struggles by businesses to compensate for losses incurred during the pandemic, and diversion of economic focus. The impact had a lower proportion on Dagaa, given its low value compared to the other two major commercial species. The quantification of fish data during a pandemic is useful to provide mitigation measures for shocks that could be anticipated in the sector for sustainable fish-food systems.
