Maori fishing projects have received cash injections from the latest Sustainable Farming Fund grants.
Tuna Aquaculture by Te Ohu Tiaki o Rangitane Te Ika a Maui Trust got $600,000.
Maori are significant eel quota holders and eel (known in Maori as tuna) is a highly valued customary, recreational and commercial species.
It is considered a delicacy and is served at marae throughout the country.
Primary Industries Minister Nathan Guy says the project will focus on learning more about young glass short-fin eels so that they can be raised in a successful and sustainable way.
Koura Aquaculture by Wai-Koura South was granted about $120,000.
It plans to develop a best practice guide for freshwater crayfish farming.
