Fishing statistics and biological data for oceanic pelagic fish around the Canary Islands

The check list of the Spanish fleet operating on this resource is registered at 600 vessels, although in fact only about 350 vessels operate annually combining the capture of tunas and tuna-like fishes specimens with other catches. 60 per cent of this fleet is made up of vessels of under 10 tons GRT. The method used is bait boat and, mainly, rod and hand line. Information on captures per species and effort for each tide since 1977 is available. Also available is the distribution per size and the specific composition of the catches landed since that date. There is a file of biological samples containing the following information: size, weight, sex, sexual maturity, stomach repletion and diverse morphometric measurements. Information on age, which has been determined by the cuts on the first spine of the dorsal fin, is available for some species. This information, together with that of other fleets operating in the area, allows for the evaluation of the resource in accordance with ICCAT.

此资源上运营的西班牙船队的核查清单登记了600艘船舶，然而实际上每年仅有大约350艘船舶参与运营，这些船舶通过捕捉金枪鱼及其类似鱼类与其他捕捞物相结合的方式进行作业。该船队的60%由总吨位不足10吨的船舶组成。采用的捕捞方法主要是诱饵船以及钓线和徒手垂钓。自1977年以来，有关各物种捕捞量和每次潮汐的努力程度的信息均有记录。此外，还有关于自该日期以来捕捞物分布大小和具体组成的资料。生物学样本文件包含以下信息：尺寸、重量、性别、性成熟度、胃部充实度和多种形态测量指标。部分物种的年龄信息，通过测量背鳍第一棘的切割来确定，亦可供查阅。这些信息，连同该区域内其他船队的运营信息，使得根据国际捕鲸委员会（ICCAT）的规定对资源进行评估成为可能。
