Spain Artisanal trap shrimp fishery - Canary Islands watersThe Canary Islands archipelago and its surrounding waters are part of the Canary region, which is located on the eastern edge of the subtropical gyre of the North Atlantic and is bathed by the Canary current fed by the Azores current (Fiekas et al., 1992). The Canary Islands act as a barrier to the Canary Current and the trade winds which introduce strong variability in the atmospheric and oceanic flows, giving rise to mesoscalar oceanographic processes, such as eddies and warm wakes, to leeward of the islands (Mittelstaedt, 1991, Hernández-Guerra et al., 1993; Arístegui et al., 1997; Barton et al., 1998). On a biological level, these phenomena entail an increase in planktonic production. Likewise, the water masses from the Northwest African upwelling displaced offshore towards the Canary Islands by the Ekman transport and the upwelling filaments may reach the eastern part of the Canary region. Consequently, this region straddles the transition between the cool, nutrient-rich waters of the coastal upwelling regime and the warmer, oligotrophic waters of the open ocean (Barton et al., 1998). All of this results in variability of the oceanographic conditions in the Canary region, both in a longitudinal and a latitudinal sense. Thus, it is expected that the effects will be manifested at the biological level, affecting the whole trophic chain.

Fishing Gear
Traps (nei)The shrimper trap is a frame inside-covered by a net o “forro”. These traps can have either one or several entries or mouths, with a trunk-conic proper for shrimps. They have one entry for putting the bait and taking out the catches. There is a modality of “floating shrimp traps”. These are constituted by a main cylindrical framework, made by a plastic mesh with two metal rings that give them stiffness. Posterior and anterior parts of the trap are conical, being the anterior outside-oriented and the posterior inside-oriented. There is an entry with a cap in the anterior part. The “matadero” is in the posterior part. Every trap carries one rigid float, tied with a nylon rope in the anterior ring of the main cylindrical body.
