Available data indicate that fishing mortality was already high in the 1890s (F=0.4) and increased to a record high in the late 1920s and early 1930s (F=0.8). After World War II, fishing mortality was reduced, but from the 1960s onwards it increased steadily to a level of F=0.6 in the early 1990s. Indices of catch per unit of effort during the last quarter of the 19th century are concurrent with the expansion of the fisheries. Stock biomass was at a low level in the 1930s but increased between the 1960s and 1980s owing to increased recruitment and improved growth. Landings were fairly stable around 55 000 t until the mid-1950s when they increased almost threefold to a record level of 170 000 t in 1989. The causes of these changes are discussed. It is suggested that changes in both growth rate and exploitation rate in young fish have been important.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Trends in population dynamics and exploitation of North Sea plaice (<i>Pleuronectes platessa</i> L.) since the late 1800s","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":" plaice, North Sea, exploitation, discards, recruitment history","OtherDescriptors":null,"Notes":null,"AnaPub":1996,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2008-04-08","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1996VZ68900034","VABBcode":null,"OpenAcc":1,"DOI":"10.1006/jmsc.1996.0142"},"refs":null,"anarec":{"AnaID":121430,"PubliDate":1996,"Pagination":"1170-1184","XtraPublOfAnaID":null,"ISBN":null,"Volume":"53","Issue":"6","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44710,"SerRR":"ICES Journal of Marine Science.
