Advances in Marine Biology : Advances Chepalopod Science Biology, Ecology, Cultivations and Fisheries 67

It is my pleasure to introduce this special volume of Advances in Marine Biology devoted to current topics in cephalopod research to a wider readership. Cephalopods—squid, octopuses, cuttlefish, and nautiluses—are highly evolved marine mollusks with diverse life histories and a wide range of habitat preferences. These rapidly growing animals have relatively short life cycles and die after a single reproduction period. Combined with a high production-to-biomass ratio, these opportunistic features earn them a place as important components in the trophic structure of marine ecosystems and as the objects of valuable capture fisheries.

Cephalopods also are noticeably sensitive to environmental variations. This has become of special concern in a time of changing ocean climate and, by itself, warrants research that adds to our knowledge of these attractive invertebrates with impressively large brains, strikingly familiar eyes, and intriguingly complex behaviours.

The first topic is cephalopod culture. Owing to their very high growth rates, short life cycles, and important markets, cephalopods are one of the more attractive candidates for marine aquaculture. This paper summarizes state-of-the-art culture methodologies for four species chosen as biological models. It addresses problems associated with transportation, water quality, nutritional requirements, and digestive physiology. Opportunities for, and present limitations to, commercialization are analyzed and research priorities are outlined.

The next review deals with fisheries management, particularly its effect on cephalopod population dynamics. This paper describes management approaches to cephalopod fisheries and underlines the essential role of forecasting in sustaining profitable harvest of these short-lived species. The need to enhance our understanding of the relationship between the environment and both population dynamics and trophic dynamics at all phases of the life cycle is stressed.
