Comparing sampling strategies for surf-zone fish communities

摘要: Beach seining is used for capturing surf-zone fishes scientific or fishery purposes. Sampling gear and different sampling approaches pose difficulties comparative analyses. We compared parallel tows (PT) beach hauls (BH) using the same seine, observing differences in species number (SPUA = number of m–2), total relative abundance (CPUA = number individuals m–2) average size. ANOVA PERMANOVA showed that both were significantly between seasons, with higher values BH. Most abundant Umbrina coroides significant interactions CPUA PT summer Diplodus argenteus BH from winter to summer. Harengula clupeola Trachinotus carolinus strategy more individuals. Sardinella brasiliensis seasons autumn respectively. Results suggest catch structure composition differ strategies, but a seasonal component associated recruitment one also influenced catch. The appears be effective time consuming. may an alternative method, results not comparable.
