Fish & Game officers are reminding local anglers to be patient this fishing season.
Fish & Game Officer Matt Osborne said the organisation planned to survey more than 1200 anglers when the season opened, on October 1, on lakes Rotoiti, Tarawera and Okataina - the three lakes which have had a three-month break from boat fishing.
He said Fish & Game was appealing for patience, as officers questioned anglers for valuable information that would help with fishery management decisions such as regulation setting and liberation strategies.
"As usual, Fish & Game staff along with honorary rangers and helpers will patrol both on water and at boat ramps, quizzing anglers on their catches - our version of 'show and tell' - measuring and weighing fish," he said.
"This year we have a new boat named 'Kotare' for our patrols, easily spotted by its bright blue colour. "
He expected the open day of the season to be a "long busy day" but an enjoyable one that would provide Fish & Game Officers with a great opportunity to interact with licence holders, while gathering data.
However he reminded anglers to keep safe.
"The opening can be a hectic time so anglers are encouraged to be patient and safe on the water, at the ramp and getting to and from the lakes. We want to see everyone enjoying themselves."
Mr Osborne said there were two changes to the regulations which affected lakes Tarawera and Rotoiti. On Lake Tarawera a new maximum size limit for wild fish has been set at 620mm, down from the previous 650mm. Wild fish are those not released from the hatchery and therefore not carrying a fin mark or tag.
Fish & Game said anglers should carry their fishing licence with them and check their regulation and guide books before heading out.
