Advances In Squid Biology Ecology And Fisheries

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 myopsids 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.

As with the previous volume, the aim of this book is to gather and synthesize 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 upwelling 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 behavior that involves vertical migrations from near-surface waters at nighttime 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.

Advances in Cephalopod Science: Biology, Ecology, Cultivation and Fisheries—volume 67 in the Advances in Marine Biology series—addresses major themes of growing research interest in the field of cephalopod research. The book is composed of four chapters incorporating the latest advances in biology, ecology, life cycles, cultivation, and fisheries of cephalopods. Each chapter is written by a team of internationally recognized authorities to reflect recent findings and understanding. The book represents a breakthrough contribution to the field of cephalopod science. Advances in Marine Biology was first published in 1963 under the founding editorship of Sir Frederick S. Russell, FRS. Now edited by Michael P. Lesser, with an internationally renowned editorial board, the serial publishes in-depth and up-to-date reviews on a wide range of topics that appeal to postgraduates and researchers in marine biology, fisheries science, ecology, zoology, and biological oceanography. Eclectic volumes in the series are supplemented by thematic volumes on such topics as the biology of calanoid copepods. Covers cephalopod culture Covers environmental effects on cephalopod population dynamics Covers biology, ecology and biodiversity of deep-sea cephalopods Covers life stage transitions in successful cephalopod life strategies

Octopus Biology and Ecology is an all-in-one resource that explains early life history stages, including age and growth maturation, distribution, migration, diet, predators and parasites related to these mollusks. Octopods are becoming a strong source of protein, with information on the species becoming more and more important to fisheries. This reference offers detailed information on the most economically important octopods in the world and addresses the management and future forecasting of octopod fisheries. Special attention is given to octopods in highly variable coastal environments as they constitute a particular challenge. Octopod populations (together with other cephalopod groups) have increased worldwide, suggesting that these commercially relevant mollusks will benefit from the conditions of the oceans of tomorrow (e.g., global warming and decreased competition and predator pressures). This is a complete resource for aquatic scientists, marine biologists, researchers, cephalopod biologists, cephalopod ecologists, fisheries and aquaculture scientists, regulators and students. ? Provides a thorough overview of the biodiversity of octopuses ? Presents a detailed information about 21 different species ? Includes a profound analysis of past, present, and future trends in octopus research
