The Department of Conservation is reminding Hawke's Bay whitebaiters that fishing hours from now until November 30 are between 6am-9pm.
The annual mid-season change in fishing hours occurs during Daylight Savings, which began on Sunday, September 25.
Regulations pertaining to fishing hours, season dates and net use have been set nationwide in order to maintain whitebait populations.
"We want to make sure an adequate number of whitebait are able to travel safely upstream and mature," said Hawke's Bay compliance ranger Rod Hansen. "That way the adults will be able to return to the Bay to spawn and provide next year's whitebait stock."
DoC has been conducting routine whitebait checks since August. Several nets have been seized along the Porangahau River this season, and DoC is also closely monitoring the Tukituki River for illegal fishing practices.
