“…Although it could not be explicitly tested, if bait‐specific differences in perch selectivity are more likely due to differences in bait size than type, which seems a reasonable assumption, then results presented here indicate that hook dimension alone may not account for the majority of the variance observed in contact selectivity estimated in hook‐and‐line fisheries. Selectivity patterns often have been inferred to result from gape limitation with respect to hook size, but fishes with a large gape relative to body length typically do not display strong shifts in selectivity with increasing hook size (Cerda, Alós, Palmer, Grau, & Riera, ; Cooke, Suski, Siepker, & Ostrand, ; Garner, Patterson, Porch, & Tarnecki (). Patterson et al., ).…”

Hook performance and selectivity of Eurasian perch, Perca fluviatilis (Linnaeus, 1758) in the Åland Archipelago, Finland

Summary The effects of two hook‐types (circle or J hook) fished with two different baits (red worms Eisenia spp., or cyprinid fishes) were examined for deep‐hooking, catch rate, mean total length, and selectivity of Eurasian perch, Perca fluviatilis, in the Åland Archipelago, Finland. The perch population available to hook‐and‐line gear was sampled with multipanel gillnets, with panels ranging from 10 to 60 mm in stretched mesh diameter. The effect of each hook then was examined for each bait by conditioning the size distributions of hook‐and‐line catches on the size distribution of perch collected with gillnets to estimate selectivity. The proportion of deeply‐hooked perch was 4.8 times greater for J hooks (0.21) than circle hooks (0.04) baited with worms and 3.7 times greater for J hooks (0.33) than circle hooks (0.09) baited with fish. Catch rates were significantly different between the two baits but not between the two hooks, with the greatest catch rate observed for the circle hook baited with worms. There was no significant difference in perch total length between the two hooks, but there was a significant difference between the two baits, with the fish bait catching significantly larger perch. Perch selection peaks between the two hooks differed by only 13.8 mm, but the selection peak with fish bait (236.4 mm TL) was 119.9 mm greater than the selection peak with the worm bait (116.5 mm TL). A substantially lesser incidence of deep hooking support the conservation benefits of circle hook use for perch, especially when catch‐and‐release is practiced. Using fish baits similar in size to those used in this experiment can avoid potentially harmful interactions between relatively small perch and anglers who place little importance on catch motives but whose satisfaction is still catch‐dependent.

“…These plans should take into account not only the biological impacts but also the increasing economic importance of recreational fisheries (Lloret 2010;Font & Lloret 2011a), the cultural heritage of the artisanal fisheries (Gómez et al 2006) and the virtues of artisanal fishing compared with industrial fisheries-in terms of ecological and socio-economic sustainability (Zhou et al 2010). Managing bait type and hook size might also constitute a simple tool to influence the amount, composition and size distribution of the fish catch in marine recreational fishing (Alós et al 2009;Cerdà et al 2010). For certain endangered species (e.g.…”

“…Despite numerous studies on recreational and artisanal fisheries in Mediterranean coastal waters (e.g. Recreational fishing in the Mediterranean is a popular outdoor activity in coastal areas, where an increasing number of local inhabitants and tourists fish for pleasure and have a large impact on the local and regional economies (Morales-Nin et al 2005;Lloret et al 2008a,b;Cerdà et al 2010;Font & Lloret 2011a,b). In the Mediterranean Sea, artisanal fisheries are characterised as commercial fishers operating in small boats, exploiting areas near the coast, using a large number of gears and techniques (which change seasonally), typically manned by a single or a pair of fishermen and targeting a high diversity of species (Guillou & Crespi 1999;Colloca et al 2004;Gómez et al 2006).…”

The biological impact and the social characteristics of different artisanal (professional) and recreational fishing techniques on the marine resources of a coastal Mediterranean area were compared. Data were from artisanal and recreational surveys carried out between 2006 and 2010. Competition between recreational (particularly spear fishing) and artisanal fishers for the natural resources is important as 52% of the 98 species surveyed were caught by both types of fishers. A total of 87 species were caught by all artisanal fishing gears together (of which 84% were retained and 16% discarded). Recreational fishing caught 58 species of which none was systematically discarded. The two fishing techniques that raise major environmental concerns are spear fishing (very selective in terms of species and/or sizes and high intrinsic vulnerability of catches) and trammel netting (highest number of species discarded and highest number of species endangered). Important challenges from the social standpoint were found that need to be taken into account in the management of coastal fisheries in the Mediterranean Sea including: progressive disappearance of the artisanal fisheries, ageing of the artisanal fisher populations and decline in the number of fishing gears used by artisanal fishers.

“…Grixti et al, 2007;Alós et al, 2008b). However, further research should re-test the hook size effect (see Cerdà et al, 2010), particularly considering the recently implemented minimum gap size of 9 mm for hooks in the largest Portuguese Natural park with a MPA (Parque Natural do Sudoeste Alentejano e Costa Vicentina). Future studies should address other potentially important factors such as depth of capture and height at which fish are released.…”
