The main aim of this study was to improve knowledge regarding the spatial distribution of cetaceans (Balaenoptera spp.) using opportunistic sightings from purse seiners targeting tuna in tropical areas of the Atlantic Ocean (Atlantic, Eastern Central, FAO major fishing area 34) between January 2003 and December 2016. Each sighting datum collected by observers on board fishing vessels targeting tropical tuna was identified at the lowest possible taxonomic level. These data were analyzed using General Linear Models (GLMs) to determine the environmental variables that favor the preferential habitats of Balaenoptera spp. compared to those of other cetacean species. It was found that the sea surface temperature and sea-current velocity-component are factors that explain the differential spatial distribution of Balaenoptera spp. Thus, the probability of observing Balaenoptera spp. specimens in coastal areas is higher when temperatures are low and currents are slow.

这项研究的主要目的是在一月份之间使用针对大西洋金枪鱼的围网捕捞者的围网捕捞者的机会性目击，来提高对鲸类（Balaenoptera spp。）空间分布的认识。 2003年和2016年12月。观察员在针对热带金枪鱼的渔船上收集到的每个观测基准均以最低的分类标准确定。使用通用线性模型（GLMS），以确定有利于的优惠栖息地的环境变量这些数据进行分析鲸spp。与其他鲸类物种相比。研究发现，海面温度和海流速度分量是解释Bal翅藻不同空间分布的因素。因此，观察到Bal翅目的可能性。当温度较低且电流缓慢时，沿海地区的标本较高。
