The Inlet » Natural History » Fish
This page is a general introduction to the fish of the Pauatahanui Inlet. You can also read about specific species as follows:
Published records (see Reference box below) show that 46 species of fish have been recorded in the waters of Porirua Harbour as a whole. We don’t know exactly how many of these were present in the Pauatahanui Inlet but from the listed species it seems likely that all of them could at least occasionally visit the Inlet. Seven of these species – lamprey, brown trout, two eels and three species of whitebait are principally freshwater fish that transit through the Inlet on their way to or from spawning grounds.
At least 14 species are resident in the Inlet throughout the year, though only nine get to adulthood in the Inlet. The others return to the sea to mature. Nine species are usually present in large numbers (abundant) and 12 are plentiful (common), though not all the common species are present throughout the year. Only three species are known for certain to spawn in the Inlet but clearly it is an important nursery area for many species.
The most abundant species are probably the Sand flounder and Yellow-eyed mullet. The large number of species of flatfish (four soles and flounders) indicate that there is a diversity of suitable habitats for flatfish in the Inlet.
