Abstract

An experiment was carried out to estimate the rate of indirect fishing mortality on juvenile Spisula solida due to the exposure time on deck. Samples were collected using a dredge from a site off Vilamoura, south coast of Portugal, during July 1994. Length of deck exposure is directly related to mortality of juveniles. It was estimated a fishing mortality rate of 0.00335 per min, due to length of exposure.
