Reel Life April 2021

- 15/04/2021
April and May signify the start of the winter spawning season for trout in the Eastern Fish & Game region.
Cooler weather and the onset of rain stimulates fish to commence the migration to spawning grounds, and this provides a great opportunity for anglers.
Big, prime rainbows are already on the move at the stream mouths around the Rotorua lakes.
Reports of good catch rates have been received from Tarawera stream mouths.
Early runs often tend to be smaller, juvenile wild fish with larger hatchery fish following and this has been confirmed by our trapping at the Te Wairoa stream, which is used mostly to collect brood fish for the Ngongotaha hatchery program.

Every year we remind anglers that winter success is much enhanced by the onset of rain, especially after a still, dry period.
As we can see from the table below, spawning fish respond to rainfall.
During five days of trapping in late May 2020, 101 fish ran the Te Wairoa stream with 53 of those running on one night (May 25th), as 32mm of rainfall occurred.
The other four nights, which were mostly dry, saw average runs of just 12 fish per night.
The water temperature, which fluctuated throughout, seemed to have little effect on the other hand.

So, warm, sunny afternoons might be enjoyable for sitting in a fold-out chair, soaking a Boobie fly, but cold, wet, miserable weather produces more fish!
Key winter locations on the lakes are any of the stream mouths as spawning trout naturally attracted to inflowing water.
Also, the places where Fish & Game release fish as maturing adult fish will tend to ‘return’ to these spots as if they were naturally spawned there.
Locations can be found in the hatchery liberation schedule found here.
