Resumo: 	Gobies were obtained monthly from the bycatch of a commercial shrimp trawler operating in the shallow waters (less than 20m depth) of the Westdiep area, Southern Bight of the North Sea, from May through December 1984. &lt;i&gt;Pomatoschistus lozanoi&lt;/i&gt; juveniles appear later than &lt;i&gt;P. minutus&lt;/i&gt; juveniles, indicating a temporal segregation of reproduction. Yearly average density of &lt;i&gt;P. minutus&lt;/i&gt; is about twice that of &lt;i&gt;P. lozanoi&lt;/i&gt;. Food consumption by the two species amounts to 1-2 g AFDW/m&lt;sup&gt;2&lt;/sup&gt;/year. Stomach analysis of several hundred gobies shows that &lt;i&gt;P. minutus&lt;/i&gt; is a food generalist that obtains most of its food from the benthos and epibenthos. &lt;i&gt;P. lozanoi&lt;/i&gt; is a more specialised feeder, strongly dependant on the hyperbenthos, on Mysidacea in particular. The absence of a food niche shift in &lt;i&gt;P. lozanoi&lt;/i&gt; when no &lt;i&gt;P. minutus&lt;/i&gt; are present suggests that present-day competition is unimportant in shaping the food niche segregation observed.
