World Squid Fisheries

Abstract

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

Growth and reproduction of the squid Illex coindetii Verany, 1839 in the central Mediterranean Sea

“…This behaviour confirms for the southern Adriatic Sea, a feature already described in other regions (for reviews see e.g. Relini et al, 1999;Sánchez et al, 1998;Arkhipkin et al, 2015;Jereb et al, 2015a). Taking into account the data on age-at-maturity of both sexes, the 'reproductive' period of I. coindetii (including maturation and spawning) covers approximately the final third of the entire life span, as already observed in previous works on this species .…”

“…Pierce et al, 2005;Payne et al, 2006;Arkhipkin et al, 2015;Jereb et al, 2015b). The determination of age and growth is critical to understand the life history and reproductive strategy of harvested species, as well as to model the dynamics of their populations, both of which are essential for assessment and for fisheries management purposes.…”

“…In European Mediterranean countries such as Italy, Spain and Greece, cephalopods are high in local diets, total catch and trade (e.g. Sánchez et al, 1998;Arkhipkin et al, 2015;Jereb et al, 2015a). In the Adriatic Sea, central Mediterranean, I. coindetii is exploited by the fishing fleets of four countries, i.e.…”

“…In the Adriatic Sea, central Mediterranean, I. coindetii is exploited by the fishing fleets of four countries, i.e. Albania, Croatia, Italy and Montenegro and its importance for their fisheries increased recently Arkhipkin et al, 2015;Jereb et al, 2015a).…”

Observations on the spawning behavior, egg masses and paralarval development of the ommastrephid squid Todarodes pacificus in a laboratory mesocosm

“…Todarodes pacificus (Steenstrup 1880) is a squid with second largest mass of commercial landings in the world (351,229 metric tons; Arkhipkin et al, 2015;FAO, 2014) and is an important prey species for a variety of vertebrate predators (Ohizumi et al, 2000;Tamura and Fujise, 2002), yet a full understanding of its life history is hampered because observation is difficult at the depths at which spawning occurs. Naturally spawned egg masses of T. pacificus have never been found in the hypothesized spawning ground.…”
