There is something in the water

Inanga (Galaxias maculatus) are the most common and smallest of the whitebait species and are commonly found at the Grovetown Lagoon. The photograph above was taken just above the road bridge onto Maori Island (Otamawaha). Inanga have an unusual lifecycle. They begin life as eggs laid in vegetation beside streams in late summer and autumn. When the eggs hatch, they are carried downstream as larvae and spend the next six months at sea. In the spring they migrate upstream as whitebait and grow into adult fish (www.doc.govt.nz).


Te Whanau Hou Grovetown Lagoon would like to enhance the fish life at the lagoon over time. To enhance fish abunance and biodiversity the society would like to do more stream side plantings, improved fish passage in the area and gain more understanding of the lagoon environment through studies and monitoring. Currently there are many different fish species at the lagoon such as long and short fin eels, flounder, bullies, common smelt and brown trout.
