  Bottlenose dolphin (Tursiops truncatus) presence and incidental 
capture in a marine fish farm on the north-eastern coast of Sardinia (Italy)

  Resumen:
   
  On the north-eastern coast of Sardinia, from November 2004 to January 
2006, the first attempt in the Mediterranean basin to obtain 
information on encounter rate, group size and incidental capture of bottlenose 
dolphins in a marine fish farm was assessed, combining direct 
observations from fish farm boats with photoidentification studies. During 15 
months of 
  research, 79 d (65.3% of the total monitored days) were spent in 
direct observation of 146 groups of bottlenose dolphins around the fish 
farm cages. There was a peak in bottlenose dolphin presence during winter. 
Photographs were taken in the fish farm area during 79 encounters on 61 
different days (totalling 34 marked individuals). The regular 
occurrence of 
  some dolphins suggests individual preferences for the fish farm area. 
The incidental bottlenose dolphin capture observed in large, loose 
predator nets (1 dolphin per month) is cause for concern, as it is 
questionable whether or not the bottlenose dolphins in the area can sustain 
incidental capture of this magnitude. The information gained from this 
study shows the necessity for further regulations to be established, both 
in the use of predator nets and management of marine fish farms.
