Titulo: Ecosystem Based-Management for small pelagic fisheries – from regional to local scale: the case of Anchovies (Engraulis encrasicolus) in Southern Tyrrhenian Sea.
Abstract:
The Anchovies’ fishery in Southern Tyrrhenian Sea (ST) is one of the most important fishing activities carried out by Italian fleet (purse seiners). Despite the notable importance of this resource and the sharp decline in catches occurred in the last decade, the only active management regulation is the minimum landing size (9 cm) and fishermen are obliged to compile an electronic logbook, recording information about caches and landings operations.
The Campania coast, located at the northern edge of the ST, is an important spawning and nursery area for small pelagic species. In this area, European anchovy (Engraulis encrasicolus) represents an important resource for the coastal communities, and, at the end of 2021, the Italian Ministry of Fishery and the Local Administration paid great attention to this sector by funding a specific research project involving both scientists and fishermen. The main objective of the project was the development of a local scale management, based on strong scientific evidence, arising from a solid agreement among fishermen and researchers, by means of a continuous data sharing leading to an adaptive approach, to promote increasing trust and transparency among participants with economic and social effects. However, the anchovy stock (management unit) in ST is referred to a wider area identified by the FAO as Geographic Sub Area 10 (GSA10) which stretches along other 4 Italian Regions. The aim of the research activity developed in this framework is to identify the spatio-temporal distribution patterns of the target species along the GSA10 (regional scale) and consequently investigate the ecological aspects of the target population along the Campania coast (local scale), historically known as the most important area for small pelagic fish production. To identify spatial and temporal variations of the distribution of anchovy along GSA10, a hierarchical Bayesian spatio-temporal model was developed whit the INLA-SPDE R-package using georeferenced catches (as biomass index and presence of the target species) from electronic logbooks for the period 2017-2022 and the environmental characteristics of fishing locations. Preliminary results showed that despite the great extension of the GSA10, the fishing grounds and the highest levels of probability of presence of anchovy are constricted in specific and distinct areas in the northern and in the southern side of the GSA10 (Campania and Northern Sicily). This aspect implies that the identified sub-populations, spatially distinct, may be considered as different management units (at local scale) for implementing an appropriate management process along the area (regional scale) or moreover that these populations are connected to the neighboring stocks of GSA9 and GSA16.
Even for small pelagic fish, identify Spatial Management Units is essential to develop the Ecosystem Based Management to better adapt regulations considering also socio and economic aspects of fisheries at different local scales.
Biografía:
Ph.D. student in “Environment, Resources and Sustainable Development”. The Ph.D. research project aims to improve the ecosystem-based approach to fisheries resources management from global to local scale. Specifically, the research activity focuses on the identification and characterization of the commercial species essential habitats in order to develop a spatial co-adaptative management for the long-term sustainability of these resources. The main research interests are related to spatial distributions, trophic relations, and assessment of small and large pelagic species. Since 2020 he is a data analyst within the Italian Fisheries Data Collection Framework, focusing on improving the quality of logbook and landings data. Since 2021 he has been involved in the MEDIAS project (MEDiterranean International Acoustic Survey) in the Strait of Sicily and Southern Tyrrhenian Sea. He has previous experiences in the assessment of Clams stock in the Adriatic Sea and small- scale fisheries in the Marine Protected Area of Southern Italy. He is also a large pelagic regional fisheries observer working onboard purse seiners for Bluefin Tuna and monitoring catches of Swordfish and tuna like species at landing places.
