Small meshed G‐minnow traps were used to assess the habitat associations of juvenile shortfinned eels in Lake Waahi, a shallow mesotrophic lake in the lower Waikato River basin, New Zealand. Five distinctive marginal habitats (raupo, aquatic macrop

Vertical distributions of adult rainbow trout (> 25 cm fork length, FL) were determined with a SIMRAD ES470 split‐beam echosounder in two 80–90 m deep lakes differing in water quality. Between November 1993 and February 1994, most trout (> 80%) w

Forty‐seven eels were captured, tagged, and released into a 420 m lowland section of the pastoral Ahirau Stream, North Island, New Zealand. Eels were marked with jet inoculations of alcian‐blue dye, and plastic tube tags were surgically inserted

Growth rates of New Zealand endemic longfinned eels (Anguilla dieffenbachii) from streams in pasture and indigenous forest, and from two hydroelectric lakes (Lakes Karapiro and Matahina), were estimated by otolith examination. Habitat‐specific grow
