    Abstract

    This paper reviews the status of marine fish populations in Scottish waters and considers current and potential threats. The inshore environments considered (shallow sandy bays, deeper and muddier areas, sea lochs, estuaries and firths) can be characterised by fish communities of 20-50 species, with some 20 species being present at any one locality. As few as 3-5 species were dominant, in terms of both numbvers and biomass, in each habitat. Mackerel (32.3%), herring (20.4%) and haddock (14.7%) dominated the landings. Both coastal fish communities and shelf stocks of commercial species have historically suffered from over-exploitation, a situation that has continued to date despite changes in management leading to their supposed protection. Other threats are identified, as is the need for conservation, while some legislative and research recommendations are made. -from Author
