What are the effects of sea warming on the fishing industry?
2019
The paper analyses the impact of Mediterranean Sea warming on some species of small pelagic fish (pesce azzurro) in the Italian fishing industry. In particular, through a time series regression model, the research examines the productivity trend in physical terms of target species of small pelagic fish from 1950 to 2016, considering the Mediterranean Sea Surface Temperatures Anomalies as an indicator of sea warming, and the Western Mediterranean Oscillation index and the North Atlantic Oscillation index as proxies of climatic variability. The research results show an evident link between the reduction of fish availability and sea warming, with potential repercussions on the incomes of the e…
Spatial Distribution and Abundance of Mesopelagic Fish Biomass in the Mediterranean Sea
2020
Mesopelagic fish, being in the middle of the trophic web, are important key species for the marine environment; yet limited knowledge exists about their biology and abundance. This is particularly true in the Mediterranean Sea where no regional assessment is currently undertaken regarding their biomass and/or distribution. This study evaluates spatial and temporal patterns of mesopelagic fish biomass in the 1994–2011 period. We do that for the whole Mediterranean Sea using two well-established statistical models, the Generalized Additive Model (GAM) and Random Forest (RF). Results indicate that the bathymetry played an important role in the estimation of mesopelagic fish biomass and in its …
Revealing environmental synchronicity that enhances anchovy recruitment in the Mediterranean Sea.
2022
AbstractSmall pelagic fishes in the Mediterranean Sea constitute about half of the total landings, of which almost one-third is European anchovy. Anchovy abundance mainly depends on early life stage and juvenile survival and growth, which are susceptible to shifts in environmental processes. Due to the commercial importance of this species, it is necessary to elucidate the processes affecting recruitment strength for effective fishery management, using environmental indices to set more appropriate harvesting limits. Here, we constructed a simple index to capture synchronicity between enrichment and retention/concentration processes, which are known to affect anchovy abundance, during the fi…
