The banning of inshore set nets and trawling should help to reduce the rate of decline around much of the country. Shame they had to use the 'dolphins' as a excuse to introduce the ban and not ban their use due to overfishing.
If anyone denies the fishery is in massive decline then give this report a read [url]www.oceansatlas.org/cds_upload/1155802173051_BrayStruik_ FishbookNZ.pdf
One last point, MAF has next to nothing to do with fishery management. The government department which controls the fishery is Mfish.
