Climate oscillations affect fish population dynamics, ecological processes and fisheries activities in marine ecosystems. In the western Mediterranean, several atmospheric indices associated with pressure oscillations have been identified as the main drivers of the abundance or availability of certain resources exploited by fisheries. The main aim of this study was to explore the association between the potential effects of the North Atlantic Oscillation (NAO) and the Arctic Oscillation (AO) on the first sale price of fresh fish at the fish market of the most representative commercial species of the fisheries in the Alboran Sea (Mediterranean Sea). We used the Pearson correlation test to investigate correlations between the atmospheric oscillation indices and the fish market price of the selected species. The results suggest that inter- and intra-annual atmospheric oscillations may have an effect on bonito ( Sarda sarda ), European anchovy ( Engraulis encrasicolus ) and catsharks ( Scyliorhinus spp. ) abundance and catchability in the Alboran Sea and, therefore, an impact on their fish market presence and price variability according to the law of supply and demand.

气候波动对奥尔博兰海北部具有重要商业价值的鱼类市场价格的影响

气候波动影响海洋生态系统中的鱼类种群动态、生态过程和渔业活动。在地中海西部，与压力振荡相关的几个大气指数已被确定为渔业开发的某些资源丰富或可用性的主要驱动因素。本研究的主要目的是探讨北大西洋涛动 (NAO) 和北极涛动 (AO) 对最有代表性的商业物种在鱼市上的鲜鱼首次销售价格的潜在影响之间的关联。奥尔博兰海（地中海）的渔业。我们使用 Pearson 相关性检验来研究大气振荡指数与所选物种的鱼市价格之间的相关性。
