Resumo: | The survival rate of Nephrops escaping through the cod-end was recently studied in the Bay of Biscay. Over the 45mm meshed cod-end was put a 15mm meshed net in order to retain the Nephrops escaping though, the cod-end. Soon after hauling escaped Nephrops were returned on the sea-bed into cages. After an inversion of 60-78 hours, the average survived rate was about 70 %. However it was found increasing with the size of individuals. The value obtained, which is only a result of- the action oh several factors, may be lower than the true value. I he evolution, of this biological parameter according to the mesh size is discussed in the scope of assessments
