The population on Aitutaki- like most of the Cook Islands- has actually been decreasing. The cooks have direct entry to NZ (and therefore Australia) so constantly lose people.
And overall, netting has probably decreased. Nobody knows really. No accurate records are kept.
The fishing on Aitutaki has improved from what it was, but the netting that remains is shallow water drag netting and it is occurring on some of the best bonefish beaches and flats on the island. This puts it into direct conflict with fly fishers. This drag netting severely impacts on the results visiting fly fishers can expect from their fishing. It doing so it destroys any chance of the island reaching its full potential as a great fly fishing destination.
I have seen and have heard of netting activity going on right under the noses of visiting fly fishers. Even on the sand bank directly in front of the resort. I know of fly fishers that refuse to return to Aitutaki because of this and I know I won't be either. I'm not going to stand on a sand flat and wonder whether someone has dragged a giant net across it the day before. I'm not going to spend $3000 to get to Aitutaki for a week on the off-chance that the netters have left a few fish for me.
The thing is that Aitutaki could easily triple the number of fly fishers fishing the island with no real impact on the fishery at all. Imagine the economic benefits of that. At the moment this potential is being totally killed by a bunch of cowboys with a big tin boat and a very large net that want to flog fish off at the local market.
