Description:
Information on the incidental mortality of dusky and common dolphins in mid-water trawl fisheries along the Argentine shelf was obtainedfor the 1990s. The Argentine anchovy is believed to be an under-exploited resource and is usually taken in purse seine fisheries. However,on the few occasions when it was the target species of large mid-water trawlers, anchovy-eating dolphins were incidentally caught. A fewincidents accounted for relatively high numbers of dolphins but in most of the cases the information obtained was insufficient for detailedanalysis. For three cases, however, sufficient information was obtained to estimate mortality rates. Nevertheless, interpretation of these ratesis difficult for a number of reasons. FV Mar Salvajecaught around 60 common dolphins (Delphinus delphis) in only a few days and in onetow 20 dolphins were caught. Biological information on 18 common dolphins (12 males and 6 females) was obtained and ages ranged from5-10 for females and 2-18 for males.
