Resumo: | The ostracod &lt;i&gt;Cyprideis torosa&lt;/i&gt; Jones,1985 is a dominant species in the meiofauna of brackish water habitats. Its production in the field over a five-year period has been calculated using two production models. The first model uses the age-distribution of shells preserved in the sediment to assess the stage-specific mortality rates and the stage durations. The second model is the size-frequency model, modified for use with development stages instead of size-classes. Productions calculated with both methods agree very well. Their values are 9.7 and 9.2 g dwt.m&lt;sup&gt;-2&lt;/sup&gt;y&lt;sup&gt;-1&lt;/sup&gt; respectively. The yearly P/B-ratio is 2.7 or 2.6y&lt;sup&gt;-1&lt;/sup&gt;, production efficiency P/A is 0.38 or 0.37. The production efficiency of &lt;i&gt;Cyprideis torosa&lt;/i&gt; nearly equals the mean efficiency of non-insect invertebrate detritivores. The species' conservative strategy and long generation time enables it to maintain a relatively high biomass with a fixed amount of food. These characteristics make it a superior competitor.
