Diel and seasonal movements of silver eels, Anguilla dieffenbachii, emigrating from a lake subject to hydro-electric control

Autor: D J, Jellyman, M J, Unwin

Publikováno v: Journal of fish biology. 91(1)

To investigate the behaviour and fate of silver female longfin eels Anguilla dieffenbachii in relation to flow variations from New Zealand's largest (700 MW) hydro-electric station, 210 A. dieffenbachii were tagged with acoustic transmitters during s

Estimation of native fish density in lowland streams by repeated electric fishing during the day and following night

Autor: Martin L. Bonnett, D. J. Jellyman, Eric Graynoth

Publikováno v: New Zealand Journal of Marine and Freshwater Research. 46:243-261

Single reaches in three lowland streams in Canterbury, New Zealand, were enclosed with stop-nets and fish removed by repeated electric fishing passes through the day and following night during base flow conditions in late summer. The proportion of fi
