Effects of fishing technique on assessing species composition in aquatic systems in semi-arid Brazil Efeitos de diferentes artes de pesca na avaliação da composição de espécies em... by ESF Medeiros, MJ Silva, BRS Figueiredo, TPA Ramos, RTC Ramos

“…The present study shows that when selecting sampling techniques to be used in aquatic systems in semi-arid Brazil, one must consider the objectives of the study, e.g. ecological or taxonomic, in order to decide on inclusion of rare species in the sampling population. Also, the effect of the sampling gear on natural abundances of fish must be considered given that some sampling techniques are highly detrimental to fish population numbers.…”
