there is an onus on the fishery owners, both state and private, to manage all aspects of their envoirnment, be it spawning grounds, river bank and bed maintenance, predator control, returning fish and smolt to sea counts, and angler management.
also with the sheep farmers and forestry owners tha planting is not done up to the stream banks, sheep numbers are not at a level as to cause over-grazing, any fertilising of the catchment area is done in the proper manner and at the correct time.
fish farmers should ensure that lice levels on their fish should be kept below the targets set by the authorities.
the state should place counters on ALL salmon and sea-trout fisheries, to ensure that within the management plan, there are accurate figures for returning and decending fish within the system. the counts from these counters should be made available to all interested parties .
what has happened to the western fisheries over the last 20 years or so is the responsability of all the users of the catchments, and as such the onus is on these people and organisations and stste authorities to sort out this sorry mess!
I'm out of the office until next week, will try to dig out the catch record data I have then. But to address the points above, yes, all these factors will impact on sea trout stocks. But the way the post is worded suggests that they are all equal, and everyone has an equal impact - NOT TRUE. Fish farms alone are by far the biggest factor in the sea trout collapse, to claim otherwise is pure fantasy. Fish farming should take a good look at itself and how the industry is regulated, if they don't the government should. But we all know thats not going to happen, the fish farmers were wise enough to join the biggest and best lobby group in the country, the IFA. Unfortunately, as with sheep farming and many other agricultural practices, business comes first at the expense of the environment, and the IFA are too powerful for the govt to really take on.
