Pursuant to SAGyP resolution No. 814/93, during August-December 1995, six INIDEP Fishery Observers trips on board of processing vessels of the Argentine fleet were carried out. They represented 256 navigation days, 232 effective fishing days, 725 fishing trawls and 2,245 trawling hours. Data measured on board were compared to those reported in the fishing log corresponding to the same cruise and submitted to the DNPyA by the Skipper. Catches observed and reported differ by 3985,7 t (28.2. ), with a maximum difference of 1,200 t in a single cruise. In the case of trawling hours, an important fluctuation of values was observed and, in two cases, the number of hours declared exceeded those actually performed (111 and 72). In the other four cruises, between 3 and 17 trawling hours less were reported. The yields (CPUE) also showed differences that ranged between 40 and 5.320 kg/h. Taking into account the fishing log data, a CPUE of 4252.8 kg/h was estimated against a real value of 6299.1 kg.....
