الوصف: Juwana waters is one of the potential fishing areas with various types of fishing gear used. Gill net fishing gear is the dominant fishing gear in Juwana waters. Midwater gill net are classified in the group of gill nets or gill nets. Differences in mesh size indirectly affect the results of fishing. The purpose of this study was to determine the best mesh size for catches in Juwana waters. The research method used was experimental fishing with the calculation of a randomized block design (RBD), 3 different treatments (mesh sizes measuring 1.3 inches, 1.5 inches and 2 inches with 9 repetitions of the study. Data were analyzed using variance (Anova) and continued by using the BNT test. The results of this study indicate that the highest number of catches is a mesh size of 1.3 inches with a total catch of 5,372 kg. Then in second place is the 1.5 inch mesh size with a total catch of 4,670 kg and the last order is the 2 inch mesh size with a total of 3,855 kg. In the BNT test analysis, the effect of differences in net size can have a significant effect on fish catches. The types of fish caught during the study were mackerel (Rastreligger sp), anchovies (Mystacoleucus padangensis) and happy fish (Polynemus tetradactylus).

الوصف: The Expert Working Group meeting of the Scientific, Technical and Economic Committee for Fisheries EWG-15-02 on Evaluation of management plans. Evaluation of the multi-annual plan for the North Sea demersal stocks was held from 16-20 March 2015 in Ispra, Italy. The report was reviewed and endorsed by the STECF during its plenary meeting held from 13 to 17 April 2015 in Brussels (Belgium)

الوصف: The principal environmental impact of driftnets is related to the bycatch of non-target species. In general driftnets have a high degree of size selectivity and can efficiently be regulated by mesh size. Few alternative fishing methods are available to catch the species targeted by driftnets, and the impact for some of these gears is controversial. Solutions are proposed to mitigate the environmental impact of driftnet fisheries by alternative fishing gears and improvement of selectivity

جغرافية الموضوع: Mediterranean Sea
الوصف: The teleosts Chelidonichthys cuculus, Trigloporus lastoviza, Serranus cabrilla and Trachinus draco, are important by-catch species, in terms of landed biomass and commercial value, from the continental shelf bottom trawl fishery off the Balearic Islands (western Mediterranean). The main biological parameters of these species were calculated from monthly biological samplings, and were used along with three years pseudo-cohorts (2008-2010) obtained from monitoring on-board of the bottom trawl fleet, to assess their exploitation level through Virtual Population Analysis (VPA) and Yield per Recruit (Y/R) analysis. Time series of fishery independent indicators based on MEDITS surveys data such as the evolution of the abundance and biomass, the distribution range, and the Conservation Status of Fish b (CSFb), were also analyzed. All four species analyzed showed growth overfishing. The reductions of the fishing effort required to reach the Y/RF0,1 reference point were lower, 66-73% depending on the species, to those reported for the target species M. merluccius (87%), but higher than that reported for M. surmuletus (53%), in the study area in the period 2000-2010. The abundance and biomass, and the distribution range did not show any trend for the period 2001-2011, whereas the CSFb showed signs of recovery that may be due to the displacement of the trawl fishing effort from the shelf to the slope during the last decade. Our results underline the necessary incorporation of monitoring and assessment of by-catch species to the management of fisheries as their populations can show a more pronounced overexploitation than target ones.
