This paper aims to develop a rapid assessment of the COVID-19 impact on the Galician (NW Spain) seafood sector, one of the most important maritime regions in the world. Here, we focus not only on the immediate COVID-19 impacts on the extractive fisheries sector, but also on the capacity of the aquaculture and the canned industries to supply seafood markets before and during the pandemic. We synthesize multiple data sources from across the seafood supply chain to show the relative initial responses and variables of recovery during a pre-COVID-19 period (2015–2019) and during the pandemic (2020). Our study shows that seafood sectors and trade were disrupted by abrupt shifts in demand, supply and limitations on the movement of people and goods, with a wide range of impacts and consequences for the seafood sectors. We find that domestic landings, Galician aquaculture production and imports and exports of seafood products (fresh, live and frozen) in 2020 showed an important decrease. In contrast, the canned production and the imports and exports of prepared and preserved seafood products followed an increasing trend during the COVID-19 pandemic. We record a change in the consumption behavior of the Galician population, which significantly increased expenditure in fresh and canned seafood products during the first confinement. Overall, the Galician seafood sectors were able to ensure the supply of seafood products to the population during the period of confinement decreed as a result of the COVID-19 crisis. Proximity to markets, investment in domestic or nearby supply chains and the development of new technological innovations helped to avoid food shortages and loss of livelihoods in Galicia. Fishers and fishing enterprises have also acted collectively to reassert their rights to provide essential and high quality seafood products to the Galician population, their livelihoods and safe working conditions, and have leveraged relationships and collaborations with their government counterparts to continue fishing.
The Galician small-scale fisheries sector has been experiencing important changes. The presence of a wide range of ecological, economic, social and institutional drivers have forced the statu quo toward new transitions with the potential to generate desirable transformative changes. Sustainability transformations mean that changes fundamentally alter the entire system’s ecological and/or social properties and functions. However, there is a limited understanding of how a transformative change may look in small-scale fisheries, when and by whom it can be triggered, supported, and implemented. To cover this research gap, the objectives of this paper are twofold: to document the current state of the art of Galician small-scale fisheries, and to evaluate the innovations and changes that occurred between 1990 and 2020, to explore whether such changes have scaled-up as seeds of desirable transformative changes and, if not, what obstacles and/or barriers have been identified in the scientific literature. We selected two cases, the Galician shellfisheries and the Marine Protected Area of Fishing Interest Os Miñarzos, to understand when and how profound changes in small-scale fisheries took place. We hypothesize that obstacles for building resilience to consolidate transformative changes once triggered are the still moderate effectiveness of the fisheries management systems, the low progress of incorporation of scientific and traditional knowledge into decision-making processes and policy arenas, the lack of studies about socio-economic contribution to coastal communities and commercialization models, and the presence of persistent ecological and economic drivers hindering desirable transformative changes.
Introduction: The exploitation of the sea cucumber (Holothuria (Panningothuria) forskali) in Ría de Vigo (NW Spain) is recent (2015) and it has been done until now with scarce or no information about some key biological aspects as reproduction, recruitment or growth. Objective: To describe the reproductive cycle of H. forskali in Ría de Vigo. Methods: We sampled fortnightly throughout 2018. We calculated gonadal condition indices (GCI) and gametogenic stages by classic histological methods. Results: The reproductive cycle of H. forskali in the Ría de Vigo is characterized by a sexual resting stage during spring, when temperature and daylight hours are lower; the beginning of gametogenesis during summer, when temperature is higher, daylight hours longer and the sea bottom is rich in nutrients; then, a period of spawns interspersed with a gonadal restoration during autumn and winter, when temperature is lower and food is scarce. Sex ratio is 1:1, however, the studied population is not synchronized, because females initiate maturation earlier. The comparison of the histological results with GCI indices suggest that GCI is a good indicator for gonadal stage. Fishery management strategies, such as a closure period, must be adapted to the reproductive stage. We recommend avoiding fishing between November and February to increase spawning potential ratio and, consequently, recruitment.
