You've lost me there; why would a commercial shoot 90mm nets in a Bass Nursery Area?
And what would he then do with the sizeable bass he catches??????
The point Sam is try to make is that nursery areas don't do much to protect small bass as commercial nets of 90 mm don't catch them any way this is why there seems to be just as many small bass in areas not designated as nursery areas as there is in areas that are.
It could be argued that it does protect those that are sizeable in the nursery for a while until they move out of the protected area.
Before you start babbling your hate waffle.
I agree 36 cm is still a juvenile bass and have petitioned for a minimum mesh size of 100 mm for the last 25 years that I've fished for bass commercially ,it would protect juvenile bass in a far greater area than a few estuaries and creeks.
Whether this would make much difference in the grand scheme of things I'm not sure, it would help increase the breeding stock but I wonder if the ecosystems of inshore grounds and estuaries would be able to support greater numbers of juvenile bass than we have already seen at times in resent years, so would a bigger breeding stock make a difference?
I doubt the offshore bass fishery has noticed a drop in catches and they probably won't for a few years yet as there are still some very good years recruitment to come into that fishery, despite what anglers say the breeding stock is still healthy enough to produce very large year classes of juvenile fish so something else has affected recruitment in the last few years and why it has effected the southern areas more than others I have no idea, perhaps the northern strain are a little hardier.
I still say there is a link with the cod having good recruitment and bass not, even though the reason for good cod recruitment has yet to bare fruit in the southern areas, baring in mind that the recent up turn of cod in the North sea came from a stock that was supposedly on the verge of extinction.
