“…Vertical migrations to surface waters at night, related to feeding, also occurs. This behavior is well known and is used by commercial and recreational fishermen who concentrate on shallow water fishing grounds at night and sunset, targeting squid using line jigging (e.g., Cabanellas-Reboredo et al, 2012a).…”

Artículo de publicación ISISome 290 species of squids comprise the order Teuthida that belongs to the molluscan Class Cephalopoda. Of these, about 30-40 squid species have substantial commercial importance around the world. Squid fisheries make a rather small contribution to world landings from capture fisheries relative to that of fish, but the proportion has increased steadily over the last decade, with some signs of recent leveling off. The present overview describes all substantial squid fisheries around the globe. The main ecological and biological features of exploited stocks, and key aspects of fisheries management are presented for each commercial species of squid worldwide. The history and fishing methods used in squid fisheries are also described. Special attention has been paid to interactions between squid fisheries and marine ecosystems including the effects of fishing gear, the role of squid in ecosystem change induced by overfishing on groundfish, and ecosystem-based fishery management

“…Epinephelus marginatus; Reñones et al 1999). In contrast, the IPB hosts the most important recreational angling fishery on Mallorca Island (Cabanellas-Reboredo et al 2012), and consequently there is substantial re crea tional fishing effort in this area (see Fig. 1 for the spatial distribution of fishing effort around Mallorca Island).…”

When gene flow is limited and harvesting is intensive, fishing may alter life histories and favour trait combinations that collectively reduce adult body size. However, empirical evidence of downsizing of adults in small-bodied coastal fish is still scarce, in part due to the lack of knowledge about the selective nature of certain fishing gears, such as recreational angling, and the difficulties in estimating the dispersion of pelagic early-life stages. Using the small-bodied sedentary coastal marine fish Serranus scriba as a model, we first empirically show that recreational angling selects for life-history traits (i.e. increased reproductive investment) that promote downsizing of adults. Second, using Lagrangian particle dispersion modelling, we show how local hydrodynamics generates patterns of limited connectivity and the emergence of meta-population structure. Finally, the life histories presently observed in isolated populations of S. scriba that experienced differential fishing pressure matched expectations of fishing-induced downsizing of adult body size. Body size is an important trait in aquatic food webs, and evolutionary downsizing might have unforeseen consequences. From a precautionary perspective, maintaining the metapopulation structure and the full range of genotypes inherent in them is important, even for smallbodied, geographically restricted fish species that are mainly harvested by recreational anglers.

“…It is also important to highlight that management of these fisheries is conditioned by the seasonality of the life cycle of squid (Cabanellas-Reboredo, Alos, Palmer, March & O'Dor, 2012;Cabanellas-Reboredo, Alós, Palmer & Morales-Nin, 2012;Moreno, da Cunha & Pereira, 1994) and cuttlefish (Guerra, 2006a;Guerra & Castro, 1988), mainly related to their high rate of population renewal and reproductive behaviour (Otero et al, 2015;Roura et al, 2013;Sánchez & Martín, 1993). In particular, the complex reproductive cycle of European squid means this species is dependent on environmental conditions, which has important implications for fisheries management (González, Otero, Pierce & Guerra, 2010;Guerra, Allcock & Pereira, 2010;Roura et al, 2013).…”

“…Fishing for squid and cuttlefish is carried out in the Galician rías (Guerra & Castro, 1988;Simón, Rocha & Guerra, 1996) when these cephalopods arrive to reproduce (Cabanellas-Reboredo, Alos, Palmer, March & O'Dor, 2012;Cabanellas-Reboredo et al, 2014;Castro & Guerra, 1990). The Ría of Vigo ( Figure 1) was selected as a study area because the biology of both squid and cuttlefish has been well studied (Castro & Guerra, 1990;Guerra & Castro, 1988;Otero et al, 2015).…”

A new methodology based in the use of fishers’ knowledge and cost‐effective tools to obtain information about marine recreational fisheries (MRF) is presented. The squid and cuttlefish fishery of the Ría of Vigo (NW Spain) was selected because it is managed in a data‐poor environment. In‐depth interviews (57) were conducted with fishers, collecting ecological and socio‐economic information. A cartography of fishing grounds based on their knowledge was obtained, while the intensity of effort and catches was mapped by the monitoring of two vessels with low‐cost GPS data loggers. The 102 shore anglers and 248 recreational boats catch 8 t/year of European squid Loligo vulgaris and 11 t/year of common cuttlefish Sepia officinalis (11% of total catches on these species in the area). Shore anglers fish from 11 ports, while boat fishers use 14 fishing grounds (covering 30 km2). Most of the catches (86%) are landed by boats, and their CPUE is higher in the outer part of the Ría of Vigo. The use of fishers’ knowledge and cost‐effective monitoring is encouraged to obtain information for the management of MRF. Given the economic contribution of MRF (260,000 €/year in direct expenses), this activity should be considered in the regulations.
