Sometimes not by a lot, but sometimes by plenty. Then look at the other CRA graphs and you can see that when the TACC is obtainable it will mostly get fully caught each year. What you can also see is how slow MPI are to react when the TACC can't be caught. Big thing though is that the CRA2 TACC was being caught or nearly caught over the past 10 years until 2015/16 where they didn't get close to the already reduced TACC. I guess that is what finally triggered MPI into a review which said the stock was more or less functionally extinct. So did the stock suddenly collapse in just a couple of years? Probably not! So how did our world leading fisheries management system not capture the massive stock decline from the commercial Catch Per Unit Effort calculations? Di they just choose to ignore it, or did they not get the 'accurate' raw data, or was it just left not analysed? Someone in that food chain should be answering some hard questions. If the Rec community are being hit with more catch restrictions because MPI and/or the commercial fleet have screwed up the management, why shouldn't we be able to hold someone responsible? |

It is only at that point will sensible long term management be put in place. Note in the sea it is almost impossible to fish a species to extinction as they have so many places to hide where we can't see them, given time the population will recover again. With respect to how the fisheries managers get it so wrong, you just need to look back at the Grand Banks of the US/Canada. My understanding from seeing a couple of documentaries on this was that the modelling being done on fish stocks was showing declines, but commercial catch was not declining much so they thought their modelling must be wrong so they started dreaming up "variables" to put into the model to "bring" stocks back up to the levels that must be there based on commercial catch, but what they were not factoring in was that the commercials were getting smarter and more efficient at catching and finding the few remaining fish that were left, until all of a sudden there were virtually no fish left and the fishery completely collapsed. Since then the fishery has been highly regulated and stocks are now rebuilding well. I am sure the NZ fisheries managers have a glass half full mentality i.e. always have a optimistic approach, when in reality if managing a natural resource they should always have the glass half empty mentality i.e. precautionary approach. Also I am sure you will find most of these fisheries scientists who are doing the modelling have massive egos who will never admit they are wrong no matter how bad things look and combining this with Senior Management in MPI and fishing companies with even bigger egos is a recipe for disaster. |
