Abstract
The fishing of the pearly razorfish (Xyrichthys novacula) is very common and extended in the Balearic Islands. During the period 2005- 2008 had been studied the evolution of this species in the marine protected area of Freus d’Eivissa i Formentera in two areas with different levels of protection. One in which there is only a temporal ban (from 1/04 to 31/08) and a second where only professional fisherman are allowed to fish when the temporal ban is finished. Main findings of the present study are that a higher fishers pressure involves a reduction of te males percentages respect females in the total capture and a reduction of the females size, which means a reduction in the number of eggs in the reproductive period. The increase of the levels of protections of pearly razorfish involves a increase in its size and also a increase of its reproductive potential which means a correct way for the preservation of this specie.
