Using multivariate adaptive regression splines to predict the distributions of New Zealand's freshwater diadromous fish
Summary 1. Relationships between probabilities of occurrence for fifteen diadromous fish species and environmental variables characterising their habitat in fluvial waters were explored using anExpand

Dispersal, disturbance and the contrasting biogeographies of New Zealand’s diadromous and non-diadromous fish species
Aim  To examine the relationship between diadromy and dispersal ability in New Zealand’s freshwater fish fauna, and how this affects the current environmental and geographic distributions of bothExpand

Differences in growth between maturing and non-maturing male Atlantic salmon, Salmo salar L., parr.
Sibling male Atlantic salmon parr that matured tended to be the larger fish in January, but their monthly specific growth rates between January and July did not differ from those of non-maturingExpand

Role of Fat Stores in the Maturation of Male Atlantic Salmon (Salmo salar) Parr
We provide evidence that in male Atlantic salmon (Salmo salar) parr, maturation is suppressed when mesenteric fat fails to exceed an undefined level by May. In nonmaturing parr the postwinterExpand

Agonistic interactions between Gambusia affinis and Galaxias maculatus: implications for whitebait fisheries in New Zealand rivers
Summary Laboratory tank studies were used to identify the outcome of behavioural interactions between Gambusia affinis (gambusia) and Galaxias maculatus (inanga), whereas field data on spatialExpand

Suppression of maturation in male Atlantic salmon (Salmo salar L.) parr by reduction in feeding and growth during spring months
Abstract Four sibling populations of Atlantic salmon parr were subjected to seasonal variations in feeding opportunity, from February to September. Growth was restricted relative to a controlExpand

Effects of turbidity on the ability of juvenile rainbow trout, Oncorhynchus mykiss, to feed on limnetic and benthic prey in laboratory tanks
Abstract The feeding rate of juvenile rainbow trout, Oncorhynchus mykiss Richardson, 1836, on small (1–2 mm diam.) Daphnia spp. in laboratory tanks was not reduced by turbidity levels up to 160Expand

Effects of logging with and without riparian strips on fish species abundance, mean size, and the structure of native fish assemblages in Coromandel, New Zealand, streams
Abstract We determined the effects of logging, both with and without a riparian buffer strip, on the native fish fauna at 27 stream sites in an exotic pine (mainly Pinus radiata) forest on theExpand

Effects of turbidity on the feeding ability of the juvenile migrant stage of six New Zealand freshwater fish species
Abstract Laboratory tank experiments were used to determine the effect of turbidity levels ranging from 0–640 Nephelometric Turbidity Units (NTU) on mean feeding rates for each species. Mean feedingExpand
