Seasonal and annual cycles in marine small‐scale fisheries (Ilhéus – Brazil)

Fish stock assessment is a crucial tool for resource management. Small‐scale fisheries are often multispecies and multigear. This study focuses on the search for patterns in the Ilhéus small‐scale fishery using landing data from 2000 to 2006 and climatic data. Ocyurus chrysurus and Ephinephelus spp....

Zusammenfassung:Fish stock assessment is a crucial tool for resource management. Small‐scale fisheries are often multispecies and multigear. This study focuses on the search for patterns in the Ilhéus small‐scale fishery using landing data from 2000 to 2006 and climatic data. Ocyurus chrysurus and Ephinephelus spp. were the most commonly landed fish. The number of fishing trips was higher in the winter, when winds were weaker and temperatures lower. When the temperature increased, catches of Seriola dumerili were higher. Coryphaena hippurus and some rays were more abundant in the summer in the presence of stronger winds, intense rainfall and higher air temperature. Large catches of Lutjanus spp. and Scomberomorus spp. were obtained in the autumn. There is an annual seasonality in the fishery, with a cyclical landing pattern regardless of the years considered. These results are important in view of climate change, and specific strategies for better fisheries management are recommended.
