Description
The aim of this volume is to gather and synthesise the research conducted on the biology (early life history stages, age and growth, maturation and fecundity), ecology (distribution, migrations, diet, predators and parasites) and fisheries (fishing areas, methods, landings, management and stock assessment) of the most economically important myopsid squids. This cephalopod group is typically associated with the seabed of the inshore coastal zone, usually resting or feeding to the bottom during day, and moving upwards during night-time. The use of substratum for the attachment of the spawned egg masses is a key aspect of the myopsid's biology. The spawning behaviour is complex, and females commonly mate with multiple males over short time periods. The squid aggregations are targeted by a commercial handline jig fishery or caught as a by-catch of the commercial inshore demersal trawl fishery. Managing and forecasting myopsid fisheries in highly variable coastal environments constitutes a particular challenge because recruitment processes are mostly driven by the environment.

Description
As with the previous volume, the aim of this book is to gather and synthesise the research conducted on the biology (early life history stages, age and growth, maturation and fecundity), ecology (distribution, migrations, diet, predators and parasites) and fisheries (fishing areas, methods, landings, management and stock assessment) of the most economically relevant oegopsid squids. This squid group dominates the pelagic, oceanic environment and large populations (namely of ommastrephids) are characteristic of the productive shelf-break oceanic boundary currents and up-welling systems, where they normally occupy epi- and mesopelagic depths. Little is known about the spawning and embryonic development of these pelagic squids. They spawn in the relatively inaccessible open sea and extrude the eggs in large gelatinous neutrally buoyant egg masses. Oegopsids play a key role on the vertical energy flow of oceanic ecosystems, acting as an important part of the biological pump from the surface to deeper waters. In fact, some species show a typical daily behaviour that involves vertical migrations from near-surface waters at night-time to mesopelagic depths above or within oxygen minimum zones during the daytime. In addition to the critical role both as prey and predator in the open ocean, some species are the target of some of the world's largest invertebrate fisheries.
