He said the normal trend at this time of year was to expect smelt on the surface early in the morning where they were easy prey for trout _ after feeding on the surface overnight.
"Later in the morning and as the sun rises higher the smelt go deeper,'' Mr Sherburn said.
"Which allows anglers to troll, spin or fly fish shallow initially, and then adopt deeper methods later _ such as deep
trolling, downriggers or jigging.''
On Lake Rotorua, He said boaties had been picking up "nice brown trout'' trolling shallow around the weed beds.
"The east side airport and marae runs, and off the Pins have been the best, with brown trout reports from Kawaha
Point as well. Successful lures include the Tassie `brown and `clown','' he said.
Mr Sherburn said brown trout began moving up the Rotorua tributaries in November as usual, though not in great numbers yet.
The seasonal movement upstream is to escape Lake Rotorua's warming waters.
"Browns and rainbows are swimming up the Ngongotaha and Waiteti streams, and shore-based anglers are
advised to target the stream mouths after dark.
"At this stage the Hamurana and Awahou haven't fired, but expect them to pick up as the summer temperatures do.''
Mr Sherburn said holidaymakers who wanted to try their hand at trout fishing were urged to buy a family licence before the end of the month, which puts them in the draw for a prize package worth more than $1600, including gear, activities and accommodation.
"This is really everything you need and more _ from fishing rods and reels to expert guidance. With the popular visitor attractions thrown in this is a very attractive prize.''
Locals and visitors alike are invited to a free boat fishing talk for beginners, which will be held at Stony Point, Lake Tarawera on Saturday, January 5.
Mr sherburn said it was a simple 'how to' talk and demonstration covering the trout and its habits, food supply and life cycle. Anglers will also be given tips on fishing methods and told how to bone and cook their catch.
