Book Description
"Landings from the American plaice fishery in the Gulf of St. Lawrence have been stable since 1963. A series of commercial catch and effort data from 1972-1980 is presented using a median smoother. The commercial CPUE however, may not be indicative of trends in the overall fishery since the large vessels of the mobile fleet do not direct their effort on plaice. Data from research vessel surveys indicate that a number of strong year-classes, especially those of 1971 and 1972 are entering the fishery. Biomass estimates for 1980 also indicate that the total plaice biomass has doubled since 1970"--Abstract.

Book Description
"Commercial catches for 1979 were analyzed. Catch per unit of effort for Danish seiners (tonnage class 0-50 an 50-150 respectively) for 1979 indicate an increase in stock abundance since 1977. Research data has been collected since 1970, and the abundance index for 1979 also indicates an increase since 1976. Despite high discard rates, total landings for 1979 were higher than the past two years. All indices show evidence of an increase in plaice stock biomass"--Abstract.

Book Description
Fascinating and instantly recognizable, flatfishes are unique in their asymmetric postlarval body form. With over 800 extant species recognized and a distribution stretching around the globe, these fishes are of considerable research interest and provide a major contribution to commercial and recreational fisheries worldwide. This second edition of Flatfishes: Biology and Exploitation has been completely revised, updated and enlarged to respond to the ever-growing body of research. It provides: • Overviews of systematics, distribution, life history strategies, reproduction, recruitment, ecology and behaviour • Descriptions of the major fisheries and their management • An assessment of the synergies between ecological and aquaculture research of flatfishes. Carefully compiled and edited by four internationally-known scientists and with chapters written by many world leaders in the field, this excellent new edition of a very popular and successful book is essential reading for fish biologists, fisheries scientists, marine biologists, aquaculture personnel, ecologists, environmental scientists, and government workers in fisheries and fish and wildlife departments. Flatfishes: Biology and Exploitation, Second Edition, should be found in all libraries of research establishments and universities where life sciences, fish biology, fisheries, aquaculture, marine sciences, oceanography, ecology and environmental sciences are studied and taught. Reviews of the First Edition • A solid, up-to-date book that advanced students and research scientists with interests in fish biology will find interesting and useful. Aquaculture International • A data-rich book that outlines much of what you might ever want to know about flatfishes. Fish & Fisheries • Well presented with clear illustrations and a valuable source of information for those with a general interest in fish ecology or for the more specialist reader. You should make sure that your library has a copy. J Fish Biology • An excellent and very practical overview of the whole, global flatfish scene. Anyone interested in flatfish at whichever stage of the economic food chain should invest in a copy immediately. Ausmarine • Because of the high quality of each chapter, written by international experts, it is a valuable reference. Reviews in Fish Biology and Fisheries
