My favourite and local fish and chip store standard fish is Hoki and that would not be affected. Although from what I have heard the hoki fishing is on the point of collasp. Shame trawling for flounders and dredeging is being allowed to continue.

I was lisetening to Newstalk ZB for part of the afternoon and the commercial guys are in denial or just plan ignorant over the stock levels of the inshore fisheries. Fish levels have been in massive decline, I suspect we are managing the last 5-10% in most cases. If anyone needs any proof, just read this report.

[b:zjk8in02]SHORT ABSTRACT[/b:zjk8in02]
Fish netted in a tidal New Zealand estuary from 1971 to 2004 declined between 1971-74
and 2001-04 by 46% in percent occupied tides, 70% in number per tide, 71% in weight
per fish, 91% in weight per tide, 48% in length per fish and 85% in length per tide.
There was a shift from Early to Mid Dominant species followed by fluctuation between
Later Dominants and, briefly, Invaders. Degree of interspecific association was
significantly dependent on food preference, a seasonal variable and level of intraspecific
association. Spring precipitation was positively related to increases in fish weight and
length, followed in the next year by increases in number, weight and length per tide.
