In the current study, data on Greek marine recreational fisheries regarding the number of individual recreational fishing and vessel licenses issued until 2014 are given. Moreover, using information from a questionnaire-based survey, based on 52 responses, recreational catches in two localities in the Aegean Sea (GSA 22: Thermaikos Gulf and Alonissos Island) are presented. According to data from the Port Authorities (Hellenic Coast Guard), an average of 86835 individual and 36120 vessel licenses were issued/renewed in the country in 2014. Concerning recreational catches as recorded, in Thermaikos Gulf the mean number of fishing days per year was 81.4 and the yearly catch per fisher was estimated to be 78 kg. In Alonissos Island, recreational fishers spent more days at sea (104 days/year) and their catch was considerably higher (293 kg/fisher), something that could be attributed to the beneficial effects of the nearby marine reserve. Finally, 29 taxa were caught in both surveyed areas, with European seabass (Dicentrarchus labrax) and gilthead seabream (Sparus aurata) exceeding 50% of the catches in Thermaikos Gulf, and white seabream (Diplodus sargus), bogue (Boops boops) and brown meagre (Sciaena umbra) contributing 45% of the total recreational catches in Alonissos Island.

希腊的岸上休闲捕鱼是否是不受管制的活动,会增加渔获量的不确定性?

在当前的研究中,给出了有关希腊海洋休闲渔业的数据,该数据涉及到2014年为止颁发的个人休闲捕鱼和船只许可证的数量。此外,使用基于问卷调查的信息,基于52份答复,介绍了爱琴海两个地区(GSA 22:Thermaikos海湾和Alonissos岛)的休闲渔获物。根据港口当局(希腊海岸警卫队)的数据,2014年该国平均签发/续签了86835个个人执照和36120个船只执照。关于所记录的休闲渔获,在Thermaikos海湾,每年平均捕鱼天数为81.4,每个渔民的年捕捞量估计为78公斤。在阿洛尼索斯岛,休闲渔民在海上停留的时间更长(104天/年),其捕捞量更高(293公斤/渔民),这可以归因于附近海洋保护区的有益影响。最后,在两个调查区域中捕获了29个分类单元,其中有欧洲鲈鱼(Dicentrarchus labrax)和金头鲷(Sparus aurata)超过Thermaikos海湾渔获量的50%,白色鲷鱼(Diplodus sargus),博格(Boops boops)和棕色微薄(Sciaena umbra)占阿洛尼索斯总休闲渔获量的45%岛。
