“…Differences in vulnerability of landing weights and revenues between fishing fleets and areas were explained by changes in species contribution to vulnerability and differences in species mean price (€·kg −1 ), highlighting the importance of considering the economic value of species for a proper understanding of the exposure of fisher communities 11 , 65 . Specifically, the higher vulnerability of multi-gear fleets in the south was mainly explained by O. vulgaris, where the fishing community highly depends on this resource 62 , 66 .…”

The degree of exposure of fishing communities to environmental changes can be partially determined by the vulnerability of the target species and the landings composition. Hence, identifying the species that ecologically most contribute to the vulnerability of the landings are key steps to evaluate the risk posed by climate change. We analyse the temporal variability in intrinsic sensitivity and the ecological vulnerability of the Portuguese fisheries landings, considering the species proportions derived both from the weights and revenues. To account for the diversification of species of each fleet, we explored the species dependence of the fishery in combination with the vulnerability of them. The analyses were carried out separately for three fleet typologies and three regions. Opposite to what has been observed at a global scale, the ecological sensitivity of the fisheries landings between 1989 and 2015 did not display a decline across areas or fishing fleets. Considering each fleet independently, for trawling, where average vulnerability was lower than in the other fleets, the sensitivity of the landings increased since the 2000s. On the other hand, the high vulnerability found in multi-gear fleets was compensated by diversification of the species caught, while purse-seine fleets targeted low vulnerability species but presented a high fishery dependence on few species. The results highlight the importance of combining information on ecological vulnerability and diversification of fishing resources at a regional scale while providing a measure of the ecological exposure to climate change.

This article presents a dataset that combines several time series of economic variables for Portugal, from 1969 to 2015, which can be used to accurately measure the change in value of different series in the fisheries sector. Raw data includes total nominal revenue from fish landings measured in thousands of euros, a consumer price index, and the nominal exchange rate of the Portuguese escudo against the US dollar (only until 1998). We use these raw data series to correct for inflation and to produce information on fish landings measured in constant prices in euros and to discuss the impact of the exchange rate depreciation in the fish sector if measured in US dollars. Data was retrieved from publicly accessible sources such as Statistics Portugal (Instituto Nacional de Estatística, INE) for fish landing revenue, AMECO (European Commission) for Consumer Price Index data, and International Financial Statistics (International Monetary Fund) for exchange rate data. The dataset is useful to academics, policymakers and advocacy groups alike for understanding the real production of the fisheries sector.

“…Ref. [14] conclude that a depreciation in the currency's value positively affects export performance. The exchange rate prediction model of Feng [18] predicts that the depreciation of the RMB will increase Chinese seafood exports to the US market; however, the sustained impact of the exchange rate on export performance is minimal.…”

“…Existing research is, however, inconclusive regarding the direction of causal relationships. On the one hand, some studies describe a supply-driven relationship and argue that the cost of industrial upgrades is driven by exchange rate volatility, resulting in a rise in the cost of upgrades, with reverberating effects on export performance [12][13][14][15]. On the other hand, others explain that demand-driven causation exists where unprocessed seafood exports are likely to negatively impact seafood export performance and revenue, leading to increased costs of industrial upgrades to meet import demands [16][17][18].…”

Dynamic Relationships between Seafood Exports, Exchange Rate and Industrial Upgrading

Few studies have examined the relationship between seafood export performance and exchange rate fluctuations. This paper investigates the short and long-term relationship between variables and the effect of currency depreciation on investment in industrial upgrading in the Namibian seafood industry. Employing the Johansen cointegration technique and a vector error correction model (VECM) on quarterly data from 2008 to 2020, we find that investment in industrial upgrading has a higher impact on exports than exchange rate fluctuations. Therefore, investment in industrial upgrading plays a significant role in mitigating the negative impact of exchange rate volatility. Key policy implications include the need to take advantage of currency depreciation to mitigate challenges to investment in industrial upgrading by increased budgetary allocations.
