Electrofishing Fish Capture and Survey Method

Ribe su osetljive na električna polja; kada su izložene odgovarajućim nivoima struje, privremeno bivaju omamljene i postaju nepokretne, što omogućava ručni ulov mrežama. Omamljeno stanje je reverzibilno; ribe se oporavljaju u roku od nekoliko sekundi do minuta nakon uklanjanja iz polja. Ovo omogućava istraživačima da nadziru ribe prisutne u definisanom području bez potrebe za mrežama ili zamkama koje promašuju male ili brzo pokretne ribe. Selektivnost i efikasnost metode zavise od električnih parametara (napon, frekvencija, talasni oblik), staništa i ribljih vrsta.
