How COVID-19 pandemic affected fisheries (catch volume and price): a case study in Europe

Portugal, with the highest per capita fish consumption and expenditure in the European Union, provides an excellent case study for examining the effects of COVID-19 containment measures on fishing activity. The present study focused exclusively on data obtained from mainland Portugal, covering the years 2015–2021. The analysis included different time periods: namely, pre-lockdown, during lockdown, and post-lockdown. The primary objective was to investigate and gain insights into the potential effects of lockdown measures on the quantity (catch volume) and price ($/Kg) of different fish species groups. During the lockdown, professional fishermen experienced lower quantities, compared to the average of previous years (2015–2019), in some months (March, April and May), of tuna (− 44%: from 85 ton to 47 ton), small pelagic fish (− 41.8%: from 4510 ton to 2627 ton), crustaceans (− 31.9%: from 94 ton to 64 ton), and bivalves (− 33.5%: from 412 ton to 274) being landed. Although prices fluctuated, only crustaceans showed a significant decrease in value (− 34.8%: from 14.85$/Kg to 9.68 $/Kg). Groundfish, flatfish, cephalopods, and other marine fish groups did not experience any significant impacts on landing quantities. Although there was some recovery in catch volume and market prices in the post- closure period, indicating a certain level of resilience in the sector, the socio-economic context indirectly exacerbated the profitability challenges faced by the fishing industry due to COVID-19. Given the potential for future socio-economic crises, policymakers (e.g., country government) and stakeholders (e.g., Fishers’ associations, HORECA) should prepare comprehensive and easily implementable measures to strengthen the sector and minimize potential disruptions.
