Abstract

The aim of this study was to analyze the effects of climate and marine variability on the catches of Lutjanus purpureus in three sectors of the Amazon Continental Shelf. Remote sensing data were compared with landings (CPUE) between 1997 and 2007 and analyzed for partial influence obtained through the Generalized Additive Model. Additionally, significant variables were analyzed through Wavelet Cross-Spectrum, and periods of high correlation between variables in space and time were identified. The results indicated a high coherence between catch per unit effort (CPUE) and environmental variables on an interannual scale, suggesting that Red Snapper fishing is mainly influenced by the seasonal effects of oceanographic variables. These results suggest that fluctuations in Red Snapper catches between 1997 and 2007 may be the result of natural processes that occur in the Amazon Continental Shelf every year in synergy with environmental variables, which are also indirectly affected by the El Niño–Southern Oscillation (ENSO) pattern.

海洋气候变率对亚马逊大陆架上Lutjanus purpureus (POEY, 1866)相对丰度的影响

本研究的目的是分析气候和海洋变化对亚马逊大陆架3个扇区紫斑蝽捕获量的影响。将1997 - 2007年的遥感数据与着陆数据(CPUE)进行比较，分析广义加性模型得到的部分影响。此外，通过小波交叉谱分析显著变量，识别出变量在空间和时间上高度相关的周期。结果表明，单位努力渔获量(CPUE)与环境变量在年际尺度上具有较高的一致性，表明红鲷鱼捕捞主要受海洋变量的季节性影响。这些结果表明，1997年至2007年红鲷鱼捕获量的波动可能是每年在亚马逊大陆架发生的自然过程与环境变量协同作用的结果，这些过程也间接受到El Niño-Southern涛动(ENSO)模式的影响。

期刊介绍： The international journal of the Japanese Society for Fisheries Oceanography, Fisheries Oceanography is designed to present a forum for the exchange of information amongst fisheries scientists worldwide. Fisheries Oceanography: presents original research articles relating the production and dynamics of fish populations to the marine environment examines entire food chains - not just single species identifies mechanisms controlling abundance explores factors affecting the recruitment and abundance of fish species and all higher marine tropic levels
