Sažetak
The aim of this study was to assess the state of fisheries resources inside of Nature Park 'Lastovsko otočje' (NP) 6 months after introducing fishing protocol in 2010. In order to attain sustainable fishing, the aquatorium of NP was subdivided into 4 fishing zones, which are to be exploited in pairs with a temporal rotation of three years. The effectiveness of adopted protocol is to be estimated by future monitoring using provided information as baseline data. Littoral fisheries resources were sampled by experimental trammel net fishing applying a structured hierarchical (three factor: fishing zone, location and site) experimental design. Analyses were performed on total fish abundance and biomass, diversity indices and multivariate abundance and biomass structure of caught assemblages. Out of 49 recorded different fish species, the most frequently observed were forkbeard, Phycis phycis, and striped red mullet, Mullus surmuletus, which were present in 93 % and 89 % of trammel net catches, respectively. Out of 16 recorded crustacean species, the dominant was spiny lobster, Palinurus elephas, with overall occurrence frequency of 58 %. No significant difference was found between species richness, total abundance or biomass when comparing the trammel net catches between the different fishing zones. Also, the abundance and biomass structure of caught assemblages is similar among fishing zones. Although CPUE (catch per unit effort being one 33 m long trammel net) was rated as ‘very good’ (x±SE=1.7±0.1 kg/net), it was evident that large specimens of commercially valuable species were only rarely caught. Average landing sizes are more than twice smaller than those maximally attainable. In conclusion, the results of this study suggest that in 6 month period of enforcing a restrictive fishing protocol no obvious benefits to littoral fisheries resources have occurred.
