Incidences were highest in near-coastal waters known to receive high pollution loads. For all species and all areas investigated, synchronous trends were found with intermediate incidences in 1984, maxima in 1987 and significant decreases thereafter. The variations are compared with trends in organochlorine residues in dab and plaice from the German Bight collected over the same period. Trends vary for different organochlorine substances, but the overall picture indicates elevated levels in the period 1984-1987 and decreasing concentrations thereafter. Although the general pattern is consistent with the trend in incidences, significant correlations were only found for malformations of dab and concentrations of p,p′-DDE. Trends in concentrations of nutrients and hydrographic factors were also investigated, indicating a significant negative linear correlation between surface water temperature and incidence of malformed embryos of dab. The hypothesis is put forward that low temperature may predispose developing fish embryos to the impact of organochlorines. © 1996 International council for the Exploration of the Sea Articles nationallicence embryonic development nationallicence German Bight nationallicence hydrography nationallicence malformations nationallicence organochlorines nationallicence Dethlefsen Volkert Bundesforschungsanstalt für Fischerei Aurβenstelle Cuxhaven Deichstrasse 12, D-27472, Cuxhaven, Germany aut von Westernhagen Hein Biologische Anstalt Helgoland Notkestrasse 31, D-22607, Hamburg 52, Germany aut Cameron Patricia Dorfstrasse 15, D-23826, Berk, Germany aut ICES Journal of Marine Science Oxford University Press 53/6(1996-12), 1024-1035 1054-3139 53:6<1024 1996 53 icesjms https://doi.org/10.1006/jmsc.1996.0128 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1006/jmsc.1996.0128 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Dethlefsen Volkert Bundesforschungsanstalt für Fischerei Aurβenstelle Cuxhaven Deichstrasse 12, D-27472, Cuxhaven, Germany aut NATIONALLICENCE 700 1- von Westernhagen Hein Biologische Anstalt Helgoland Notkestrasse 31, D-22607, Hamburg 52, Germany aut NATIONALLICENCE 700 1- Cameron Patricia Dorfstrasse 15, D-23826, Berk, Germany aut NATIONALLICENCE 773 0- ICES Journal of Marine Science Oxford University Press 53/6(1996-12), 1024-1035 1054-3139 53:6<1024 1996 53 icesjms Metadata rights reserved CC BY-NC-4.0 http://creativecommons.org/licenses/by-nc/4.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-oxford
