Organisers of a project to increase the population of patiki (black flounder) in a Hawke's Bay river say it's been an unqualified success.
Project Patiki was launched in November last year by a group from Kohupatiki marae with the aim of boost population of the fish in Ngaruroro River near the township of Clive.
The flounder and eels have been monitored and tagged monthly since then.
Spokesperson Tom McGuire says says throughout the 12 months of monitoring no tagged fish were caught a second time.
Mr McGuire says one concern is that the habitat for flounder in some parts of the river has been covered by silt and weed.
He says there's been great support for the project from the regional council, Fish and Game, Department of Conservation and scientists from Massey University.
Mr McGuire says there are plans next year to monitor patiki in the Tukituki and Tutaekuri rivers.
