In total, 54 fish species were caught and 72 different prey items were identified. Fish species consumed<br \/>\nfrom only a few up to >30 different prey species, suggesting the presence of both opportunistic and more specialized feeders. We found no significant differences between years or switches in<br \/>\nfood source with fish size. The trophic positions of the Wadden Sea fish community ranged from 2.0 to 4.7, with most trophic positions above 3.0. In the past, (near)-resident species were the most abundant guild in spring, and juvenile marine migrants in autumn. At present, all guilds are pre sent in similar but low abundances. The (near)-resident community consisted of about 20 species that fed primarily on amphipod crustaceans, brown shrimps and juvenile herring. There was only a slight overlap in diet with the group of juvenile marine migrants (5 species of juvenile flatfishes<br \/>\nand clupeids), whose preferred prey were copepods, polychaetes and brown shrimps. About 15 species of marine seasonal visitors showed an overlap in diet with both the (near)-resident and the juvenile marine migrants, especially for brown shrimps and to a lesser extent herring and gobies.<br \/>\nOur results illustrate (1) the pivotal position of a few key prey species (amphipod crustaceans, brown shrimps, juvenile herring and gobies) for the coastal Wadden Sea fishes and (2) that the substantial prey overlap in the diet of some predators cannot exclude intra- and inter-specific<br \/>\ncompetition among these predators.<\/p>\n","protected":false},"author":1,"featured_media":6541,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[13],"tags":[],"class_list":["post-7659","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-science"],"_links":{"self":[{"href":"https:\/\/marinesites.nl\/index.php?rest_route=\/wp\/v2\/posts\/7659","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/marinesites.nl\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/marinesites.nl\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/marinesites.nl\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/marinesites.nl\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=7659"}],"version-history":[{"count":1,"href":"https:\/\/marinesites.nl\/index.php?rest_route=\/wp\/v2\/posts\/7659\/revisions"}],"predecessor-version":[{"id":7661,"href":"https:\/\/marinesites.nl\/index.php?rest_route=\/wp\/v2\/posts\/7659\/revisions\/7661"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/marinesites.nl\/index.php?rest_route=\/wp\/v2\/media\/6541"}],"wp:attachment":[{"href":"https:\/\/marinesites.nl\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=7659"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/marinesites.nl\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=7659"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/marinesites.nl\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=7659"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
