For some species these large groups may be the only form of reproduction, the high fish numbers briefly giving a false impression of stability and abundance—an ‘illusion of plenty’. They are often a focus for intensive seasonal fishing because of their predictability and because many important commercial fishes form them. Highly vulnerable to overexploitation, many aggregations and their associated fisheries, have disappeared or are in decline. Few are effectively managed or incorporated into protected areas. Aggregations are not well understood by fishery scientists, managers and conservationists and their significance little appreciated by fishers or the wider public. To ensure their persistence to replenish important fisheries in coral ecosystems, maintain their ecosystem function and continue to delight divers, a significant change in perspective is needed to foster protection and management.. .This book provides comprehensive and practical coverage of the biology | | 出版日期 | Book 2012 | | 关键词 | Animal aggregations; Fisheries; Oceanography; Reef fishes; Reproduction; Fish and Wildlife Biology; marine | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-007-1980-4 | | isbn_softcover | 978-94-017-8389-7 | | isbn_ebook | 978-94-007-1980-4Series ISSN 2542-890X Series E-ISSN 2542-8926 | | issn_series | 2542-890X | | copyright | Springer Science+Business Media B.V. 2012 |
