Thread: Ruahine deer control

Well a fishing anecdote would be the Taupo fishery. When I started fishing, the daily limit was 8/day. The fish were plentiful enough and often big and fat.
Then they reduced the limit to 3/day. Quickly the behaviour changed to be more and more catch and release. Trying to up-size your catch because after keeping 2, you were down to 1 left for the day.
Funnily enough, the fish became more plentiful, and year by year smaller and smaller as there were more competing for food in the lake.
