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.
气候振荡会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，已经确定了几种与压力振荡相关的大气指数，它们是渔业开发的某些资源丰度或可用性的主要驱动因素。本研究的主要目的是探索北大西洋涛动（NAO）和北极涛动（AO）对阿尔沃兰海（地中海）最具代表性商业鱼类的鱼市场新鲜鱼首次销售价格的潜在影响之间的关联。我们使用皮尔逊相关检验来研究大气振荡指数与所选物种鱼市场价格之间的相关性。结果表明，年际和年内大气振荡可能会对阿尔沃兰海的鲣鱼（Sarda sarda）、欧洲无须鳕（Engraulis encrasicolus）和长尾鲨（Scyliorhinus spp.）的丰度和可捕性产生影响，从而根据供求规律影响它们在鱼市场的存在和价格变化。
