Abstract

The fishing activity with purse seines in the Aegean Sea accounts for almost half of the pelagic fish excluding anchovy (Engraulis encrasicolus Linnaeus, 1758) in Turkey. In this study, we aimed to analyse the catch amounts of some important pelagic species caught by Aegean purse seiners between 1973 and 2019. While mid-1990s are the most captured years for the European pilchard (Sardina pilchardus Walbaum, 1792) in Aegean Sea and also Turkish Seas, this amount has decreased at the level of 10000 mt in the mid-2000s and remained similar amounts up to now. Though European pilchard was the most caught species in the Aegean until 2011, this has changed in favour of anchovy in the last decade. Recently, almost all pelagic species such as mackerel (Scomber scombrus Linnaeus, 1758), chub mackerel (Scomber japonicus Houttuyn, 1782) and bogue (Boops boops Linnaeus, 1758) have been caught from the Aegean Sea in Turkey. In the study, the production of these species in the historical period was tried to be associated with the regulations implemented with circulars and notifications, and the problems preventing the sustainable use of these species that were caught by purse seiners were determined and solutions were proposed for the future.
爱琴海被围网捕获的一些远洋物种的历史登陆数据分析
在土耳其,除凤尾鱼(engrulis encrasicolus Linnaeus, 1758)外,爱琴海的围网捕鱼活动几乎占了中上层鱼类的一半。在这项研究中,我们旨在分析1973年至2019年爱琴海围网捕获的一些重要远洋物种的捕获量。虽然1990年代中期是爱琴海和土耳其海欧洲沙丁鱼捕获最多的年份(Sardina pilchardus Walbaum, 1792),但这一数量在2000年代中期下降到10000吨的水平,到现在仍然保持类似的数量。尽管在2011年之前,欧洲沙丁鱼是爱琴海捕捞最多的物种,但在过去的十年里,凤尾鱼的捕捞量有所改变。近年来,在土耳其爱琴海捕获了鲭鱼(Scomber scombrus Linnaeus, 1758)、鲐鱼(Scomber japonicus Houttuyn, 1782)和鲭鱼(Boops Boops Linnaeus, 1758)等几乎所有的中游鱼类。在研究中,试图将这些物种在历史时期的产量与通过通告和通知实施的法规联系起来,并确定了阻碍围网捕捞这些物种可持续利用的问题,并提出了未来的解决方案。
