| Resumo: |
The <i>Pomatoschistus minutus</i> (Pallas) and <i>P. lozanoi</i> (de Buen) stock of the ebb-tidal delta of the former Grevelingen estuary was sampled monthly from September 1992 to October 1993. Sagittae were extracted and the areas of the sagitta and sulcus acusticus were measured with a digitizer. The frequency response and auditory threshold of these two sympatric goby species were determined from the ratio of the sulcus acusticus area to the sagitta area (S:O ratio). The S:O ratio of <i>P. minutus</i> increased while in <i>P. lozanoi</i> the S:O ratio was constant with increasing standard length. The average S:O ratio of <i>P. lozanoi</i> was significantly higher than that of <i>P. minutus</i> of the same mean length, which makes the former more sensitive to sound frequency. The S:O ratios of these two sympatric fishes were lower than the S:O ratios of demersal and pelagic fishes available from the literature. An interspecific growth difference of sagitta and sulcus acusticus was observed. The sagitta and sulcus acusticus of <i>P. minutus</i> are larger than those of <i>P. lozanoi</i> of the same length.
