In‐stream habitat suitability criteria for feeding inanga (Galaxias maculatus)

摘要: Abstract Inanga (Galaxias maculatus Jenyns) are the basis of an important recreational and commercial freshwater fishery that has declined over past 100 years, probably because habitat degradation in developed areas. Maintenance suitable stream flows for inanga is one means protecting fishery. Observations use by drift‐feeding were made three streams. Most feeding stationary current taking food items from drift sometimes surface. Drift‐feeding locations related to patterns water velocity, with at where concentrated food, velocities sufficiently low allow fish hold position. The mean velocity did not vary significantly between streams, although range used did. Optimum 0.03–0.07 m s‐1, comparable brown trout (Salmo trutta) velocities, when adjusted differences size...
