A project organised by a team from Kohupatiki Marae in Hawke's Bay aimed at increasing the population of black flounder in their local river is seeking support from locals.
The group, which is working with the regional council, launched Project Patiki in November to monitor the number of fish at three sites along the Ngaruroro awa, commonly called the Clive River.
Spokesperson Tom McGuire says weighing and tagging of black flounder is going well.
He says white tags are attached to the head, middle and tail of each fish so the team can track their movements.
Mr McGuire says the group is keen for anyone who catches a tagged fish, to contact either the marae, the regional council or Fish and Game.
Tom McGuire says pollution from orchards and farms and less water in the river, threatens the survival of the black flounder as well as other fish species.
