  1. To our knowledge, this is the first inclusive assessment of the status of Sparidae fisheries in the territorial waters of Kuwait, integrating information on catch trends, consumer preferences, recreational fishing behaviour, and molecular based identification of fish species by DNA barcoding
  2. Fisheries landing data were obtained from the official fisheries bulletin released by the Kuwait Central Statistical Bureau. Surveys were conducted to assess consumer preferences on seabream species, landed seabream species, and the behaviour of recreational anglers towards seabream species. DNA barcodes were generated to authenticate commercial seabream using the mitochondrial cytochrome c oxidase subunit I (COXI) gene and then compared with GenBank sequence entries; these sequences were then used to construct a neighbour‐joining (NJ) phylogenetic tree.
  3. Yellowfin seabream Acanthopagrus latus was the prime and most favoured commercial seabream species (45%), followed by Sparidentex hasta, which was the top‐rated secondary, unassessed seabream species. Approximately 54% of households conduct recreational fishing more than twice a month, and most (77%) primarily target S. hasta and Ac. latus. Consumer demand for secondary seabreams, which were not assessed and are listed in the bulletin under the category ‘others’, was evident.
  4. The NJ phylogenetic tree revealed that Arabian Gulf seabreams, including those of Kuwait, are genetically different from their counterparts inhabiting neighbouring waters.
  5. The data presented here highlight the urgency to modify the existing fisheries list using accurate identification tools, such as DNA barcoding, for the sustainable and conservation‐oriented management of local fisheries, which are in decline.

科威特的商业鲷(Performformes:Sparidae)的着陆,消费和DNA条形码

  1. 据我们所知,这是对科威特领海Sparidae渔业状况的首次包容性评估,整合了有关捕捞趋势,消费者喜好,休闲捕鱼行为以及通过DNA条形码进行分子鉴定的信息
  2. 渔业登陆数据是从科威特中央统计局发布的官方渔业公告中获得的。进行调查以评估消费者对鲷鱼种类,陆栖鲷鱼种类以及休闲垂钓者对鲷鱼种类的行为的偏好。使用线粒体细胞色素C氧化酶亚基I(COXI)基因生成DNA条形码以认证商业鲷,然后将其与GenBank序列条目进行比较;然后将这些序列用于构建邻居(NJ)的系统发育树。
  3. 黄鳍鲷(Acanthopagrus latus)是主要和最受欢迎的商业鲷鱼种类(45%),其次是Sparidentex hasta,后者是评价最高的次要未经评估的鲷鱼种类。大约54%的家庭每月进行两次以上的休闲捕捞活动,而大多数(77%)的家庭主要针对S. hastaAc。拉图斯。消费者对次级海鲷的需求是显而易见的,该需求未进行评估,并在公告中列为“其他”类别。
  4. 新泽西州的系统发育树显示,包括科威特在内的阿拉伯海湾鲷在基因上与居住在邻近水域的鲷类在基因上有所不同。
  5. 此处提供的数据突显了迫切需要使用准确的识别工具(例如DNA条形码)来修改现有渔业清单,以便对正在下降的地方渔业进行可持续和以保护为导向的管理。
