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
