From penguins to pelicans and cormorants to kingfishers they all love to eat fish. We don’t want to kill them of course, just exclude them from the pond, cage or raceway.
We have high density polyethylene bird netting with 20cm stretched mesh in a fetching red/burgundy twine 380D/12 which we currently supply to the largest shrimp farmer in the world Central Proteinaprima in Indonesia. For grebes, night herons and their ilk we recommend a 50 mm bar length (10 cm stretched) and if your problem is the malachite kingfisher you will need a 40mm bar length (8 cm stretched mesh).
