The exponential abundance increase of a sub-tropical species, boarfish (Capros aper), as well as the sea bottom temperature increase in the continental shelf of the Bay of Biscay (France) over the three last decades are reported. This species was rare in the seventies and is now a dominant one. This is a small bathy-demersal, probably short-lived species with few predators (probably because of the presence of strong spines) and not exploited by fisheries. In the same time, a significant temperature increase in the bottom waters is observed during the breeding season of this population. The boarfish abundance increase is related to the warming, its ability to invade and the absence of predators as well as the absence of fishing.
据报道，在过去三十年里，亚热带物种棘鲷（Capros aper）数量呈指数级增长，同时法国比斯开湾大陆架的海底温度也在上升。该物种在七十年代较为罕见，如今已成为优势物种。这是一种小型的底栖鱼类，可能寿命较短，几乎没有天敌（可能是因为有坚硬的棘刺），也未被渔业捕捞。与此同时，在该种群的繁殖季节，观测到底层水域温度显著上升。棘鲷数量的增加与气候变暖、其入侵能力、缺乏天敌以及未受捕捞有关。
