Avoidance reactions of fish in the trawl mouth opening in a shallow and turbid lake at night

Popis výsledku v původním jazyce

Fish avoidance behavior in the trawl mouth at night was investigated in the extremely shallow and turbid Lake Neusiedl, Austria. White bream (Blicca bjoerkna), bleak (Alburnus alburnus) and razor fish (Pelecus cultratus) were dominant fish species in thetrawl catches. To evaluate fish reactions, a fixed frame benthic trawl with three electricity modes (without electricity, with continuous electricity and with interrupted electricity) was used and the achieved fish abundances, biomasses and size structures were compared between modes. Simultaneously, the dual-frequency identification sonar (DIDSON) monitored fish abundance, biomass and size in front of the trawl during tows with different modes. We did not find differences in achieved fish abundance orbiomass when tows with different electricity modes were compared. The length frequency distribution of fish was not significantly different between modes, but trawls with the two electrified modes contained a higher proportion of fish la
