The pH values preferred and avoided by adult stages of inanga (Galaxias maculatus) , common bully ( Gobiomorphus cotidianus) , common smelt (Retropinna retropinna) , and redfinned bully (G. huttoni) , were determined in a gradient tank (pH ranges of 3.2–11.2). Juvenile stages of inanga, common bully, shortjawed kokopu ( Galaxias postvectus) , koaro (G. brevipinnis) , banded kokopu ( G. fasciatus) , shortfinned (Anguilla austra...
Avoidance of suspended sediment by the juvenile migratory stage of six New Zealand native fish speciesNARA Subscribed
The avoidance response of the migratory juvenile stage of six species of diadromous fish to different levels of suspended solid (SS) was determined in the laboratory using a two‐choice avoidance tank. Trials were mostly conducted with resuspended sediment from the outlet of Lake Waahi, New Zealand, but a series of tests was also conducted with kaolin for comparison. Banded kokopu (Galaxias fasciatus) was the most sensitive spe...
