This study deals with D.cuneata, a small soleid listed among the spp of NEAFC Recommendation 2 and exploited by the 'artisanal' trawlers in the South of the Bay of Biscay. The gonads/gutted fish wt ratio has been calculated throughout a yr, and shows that young Dicologoglossa are able to reproduce at age-group II. Spawning takes place during the 3rd quarter. Growth has been determined by otolith reading and length frequency analysis; Bertalanffy's and Gompertz's equations parameters have been studied, and attempts to estimate the instantaneous rate of total mortality have been made. The results are: male Z 3-5=0.74 and 0.83, female Z 3-5=0.96 and 1.35. Selectivity experiments carried out on board of R/V 'La Palagia' give a selection factor of 3.9. The...
