The whitebaiting season is underway, and it comes with a reminder about the strict regulations that are in place to ensure some protection for the native fish.

The season runs from August 15 until November 30, except on the West Coast, where it runs from September 1 to November 14.

DOC freshwater scientist Jane Goodman said the regulations are important as they help ensure whitebait survive for future generations to admire and enjoy.

She said unfortunately fish numbers have declined, so they need to be fished responsibly.

There are strict rules around fishing methods, locations, legal fishing times and net size, and any illegal whitebaiters can be fined.

Goodman said habitat protection is also important and young fish need to be able to travel upstream, to mature and breed.
