Description: Butterfish is an endemic species of kelpfish found in shallow waters around the New Zealand coast. They are more abundant south of East Cape, especially around Cook Strait, where they are caught year round in set nets. Butterfish start life as female and about 50 percent later develop into males.
Ecological concerns: The unknown status of stocks and population size, unknown sustainability of catch levels, absence of research, the lack of a management plan and the bycatch of non-target fish species. Restrictions on set netting introduced in May 2008 have reduced the risk of catching endangered Hector’s dolphins. Recent changes allowing inshore set net fishing in the top of the South Island has increased the risk of dolphin capture.
Economic value: Butterfish is sold in New Zealand.
Best option: Butterfish caught in areas with minimal risk to Hector’s dolphins (e.g. east and north coast of the North Island).
