Tuna fisheries have been identified as one of the major threats to populations other marine vertebrates, including sea turtles, sharks, seabirds and mammals. The development technical mitigation measures (MM) in is part code conduct for responsible fisheries. An in-depth analysis available literature regarding bycatch tuna with special reference elasmobranchs was undertaken. Studies highlighting promising MMs were reviewed four (longline, purse seine, driftnets gillnet, rod line –...
Abstract In recent decades, small-scale fisheries (SSF) activity along the Basque coast (eastern Cantabrian) has declined, which led remaining vessels to undergo notable shifts in their targeted species and therefore fishing gears used, aimed at enhancing efficiency. Within that context, this study combines logbooks sales notes spanning from 1995 2022 assess inter-annual seasonal variations main target across different gears, namely ‘fleet segments’. Results reveal spring Atlantic mackerel...
Within the first attempt to assess marine recreational fisheries (MRF) along coastal villages of Basque Country (Eastern Cantabrian Sea), off-site surveys were carried out from 2015 2019 estimate captures main targeted species by shore fishing, boat fishing and spearfishing. Phone calls got better response rates (>50%) than email questionnaires (<25%). Spearfishing population was smaller (1000 licenses, <2% total MRF effort) younger, whereas fishers (5000 9% generally...
Maurolicus muelleri is a significant component of the marine ecosystem and has potential to be valuable fishery resource. However, in Bay Biscay, its primary biological traits remain unclear. This study presents data on length distribution, age, growth, maturity ogive, spawning season, batch fecundity, sex ratio for captured Biscay. The results showed that spring, adult spawners (ages 1 2) were dominant catches, while September, immature juveniles (age 0) born spring mostly found. Using...
Follicular atresia is an energy-saving oocyte resorption process that can allow the survival of female fish when environmental conditions are unfavourable and at expense fecundity. This study investigated transcription levels apoptosis autophagy-related genes during in European hake show episodes increased follicular throughout reproductive cycle. 169 individuals were collected from Bay Biscay, ovaries analysed using histological molecular methods. Different histologically detected 73.7%...
Mistrust between scientists and non-scientist stakeholders is a key challenge in fishery management. The support of management with complex models difficult, as these cannot easily communicate their results to end users, resulting lack confidence. As an example, the life cycle European eel raises problems coordination discussion among multiple actors involved species’ GEREM model has been proposed tool for estimating recruitment, but its complexity, which essential addressing characteristics...
The European eel is critically endangered (IUCN, 2020) due to several factors (climate change, barriers migration, pollution, unsustainable exploitation, illegal trading and poaching, pathogens). However, the relative effect of these can hardly be quantified. Anguillicola crassus a nematode known as one most harmful parasites for eel. Being hematophagous inducing serious alterations swimbladder, it reduce swimming performances thus may impair silver migration reproduction. Since its...
Somatic parameters' estimation of megrim (Lepidorhombus whiffiagonis), an economically important flatfish species and relevant one in the benthic community, is essential fisheries biology. It helps us to deepen our understanding life history traits adequate stock assessment fishery management. Le Cren's condition factor (K), weight-length relationships weight conversion factors were studied for more than two decades time-series (1998–2019) wide area with a fishing activity distributed into...
