Book Description
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.

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 worlds largest invertebrate fisheries.

Book Description
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

Book Description
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

Book Description
This two-volume work is a testament to the abiding interest and human fascination with ammonites. We offer a new model to explain the morphogenesis of septa and the shell, we explore their habitats by the content of stable isotopes in their shells, we discuss the origin and later evolution of this important clade, and we deliver hypotheses on its demise. The Ammonoidea produced a great number of species that can be used in biostratigraphy and possibly, this is the macrofossil group, which has been used the most for that purpose. Nevertheless, many aspects of their anatomy, mode of life, development or paleobiogeographic distribution are still poorly known. Themes treated are biostratigraphy, paleoecology, paleoenvironment, paleobiogeography, evolution, phylogeny, and ontogeny. Advances such as an explosion of new information about ammonites, new technologies such as isotopic analysis, tomography and virtual paleontology in general, as well as continuous discovery of new fossil finds have given us the opportunity to present a comprehensive and timely "state of the art" compilation. Moreover, it also points the way for future studies to further enhance our understanding of this endlessly fascinating group of organisms.

Book Description
Shellfish is a broad term that covers various aquatic mollusks, crustaceans and echinoderms that are used as food. They have economic and ecological importance and have been consumed as food for centuries. Shellfish provide high quality protein with all the dietary amino acids essential for maintenance and growth of the human body. Shellfish are a major component of global seafood production, with shellfish aquaculture rapidly growing in recent years. There are many different processing methods used across the world. Shellfish are very perishable foods and must be preserved just after catching or harvesting. This makes the preservation of seafood a critical issue in terms of quality and human health. To date there have been a number of books on seafood processing and preservation, but all of them have been mostly focused on fish. Shellfish Processing and Preservation is the first reference work to focus specifically on shellfish, providing comprehensive coverage of the production methods, biological makeups and preservation methods of all major shellfish species. Individual sections focus on crustaceans such as shrimps and prawns, crabs and lobsters plus molluscans including mussels, scallops and oysters. Cephalopods such as squid and octopus are also covered in depth. For each species processing and preservation methods such as chilling, freezing, canning and curing are examined, plus the important safety aspects specific to each shellfish type. Shellfish Processing and Preservation is an essential publication for any researchers or industry professionals in search of a singular and up-to-date source for the processing and preservation of shellfish.
