Herbicide Treatment for Aquatic Pest Plants Opposed
The Government and electricity giant Mighty River Power want restrictions lifted on banned pesticides for aquatic weed control.

He also questioned the consultation saying there were several interested parties including Watercare and the Auckland District Health Board who were not properly notified.

Round Goby Diet Increases Weight of Smallmouth Bass - Research demonstrated the ecological trade-offs going on with invasion of round goby; the positive side is that the fish, particularly smallmouth bass, seem to be in better condition which can lead to faster growing, healthier fish. But a largely negative implication of this is that fish that grow faster tend to live shorter lives. There could be increased mortality in the fish in these lakes.
