I didn't say you had mentioned it Steve, but I'm sure it won't be long before the pair trawler skippers (or more likely the owners and their spokesmen) announce that global warming or some other environmental factor is the cause of the drop in bass numbers in the south west. What I am saying is that if global warming is real, which it does appear to be going by the winters we haven't had in recent years, then there should me more bass all around the UK coasts. It would not be a reason for a drop in numbers in the south because that area is nowhere near the limit of the southern range of the species.
And yes I DO have a bias against commercial fishermen. That is because I am an angler, and commercial fishing as it is carried out now, is NOT in my interest. It is not in the interests of anglers for commercial fishermen to kill bass and cod that are capable of reaching 20lb and 40lb when they are barely a pound in weight. It's even less in my interest for them to kill them at six inches and dump them back into the sea, having wrecked the sea bed to catch them.
