Norway lobster (Nephrops norvegicus) is commercially exploited by bottom trawls and creels. In the Adriatic Sea, Norway lobster is predominantly caught by bottom trawls, both on the open sea and in channel areas, while a smaller portion is caught by creels operating in the channel areas. Although creels have low fishing efficiency compared to bottom trawls, their advantage is that they catch almost exclusively large Norway lobster specimens, with higher market value. One possible reason for the low fishing efficiency of the creels is that Norway lobster has difficulties finding the entrance into the creel. In order to test this, a creel with six entrances was designed and its catchability was compared with commercial creels in spring 2018 in Brač and Hvar Channels. Preliminary results showed that the average number of Norway lobsters caught per longline with the standard creel design was 4.39 ± 2.88, while the new creel design caught 3.73 ± 2.71 individuals per longline. There was no significant difference in catchability between the two creel designs.
