Resumo: 	The influence of the salinity on the performance of the sibling species &lt;i&gt;Tisbe holothuriae&lt;/i&gt; and &lt;i&gt;T. battagliai&lt;/i&gt; in pure and mixed cultures was studied, using laboratory stocks adapted to 32 pro mille for over 175 generations. Cohort studies show that &lt;i&gt;T. holothuriae&lt;/i&gt; has higher growth rates (R&lt;sub&gt;0&lt;/sub&gt; and r) at 32 pro mille, &lt;i&gt;T. battagliai&lt;/i&gt; at 20 pro mille. The latter's life cycle is much less affected by the difference in salinity. 'De Wit' replacement series were used to study competitive interactions. Without water renewal, &lt;i&gt;T. holothuriae&lt;/i&gt; eliminates its sibling species in less than 2 generations, apparently through chemical interference. With water renewal, i.e. when exploitation competition becomes relatively more important, &lt;i&gt;T. holothuriae&lt;/i&gt; still proves superior at 27 pro mille but the two species are competitively almost equal at 20 pro mille. The two species co-occur &lt;i&gt;in situ&lt;/i&gt; during autumn, but their differential predominance at different sites is not explained by the effect of salinity.
