| Abstract |
Sand gobies of the genus Pomatoschistus are the most abundant fish in the shallow coastal areas of the North Sea. P. lozanoi has a somewhat specialised diet feeding mainly on a few pelagic and hyperbenthic species: Temora longicornis, Schistomysis species and juvenile Pomatoschistus minutus together supply more than 70% of the energy in most months. In August the species shifts to benthic and epibenthic feeding: juvenile Crangon crangon and radioli of Lanice conchilega are the main food. Numerically the same species are dominant in most months. In December and August the amphipods Microprotopus maculatus and Pariambus typicus, in June cypris larvae and the harpacticoid Microarthridion littorale are most frequently eaten. Thus, Pomatoschistus lozanoi is an unusual demersal fish, dependent throughout its life on the secondary and tertiary production in the water column. |
