Aquaculture strikes back in Scotland

[Bradan]

hi bradan, the fact that 16% more treated thsn untreated adults returned in no way proves that the 16% mortality is attributable to sea lice.
i have emailed 4 times , made 3 written requests and 1 phone call, and not only will they not supply any figures but also fail to respond to any communications.

What does it prove then? The only difference between the groups was that one group was treated to make them more resistant to sea lice, and the other wasn't. All other factors - size, age, condition, time of release, was the same. What do you suggest is responsible for the 16% increased survival in treated fish?

As I asked, PM me with details of requests - not something for public consumption. I may be able to help.

inland fisheries ireland have an interesting study on their web site about predation of cormorants on fish, its findings on smolt predation make interesting reading.

Interesting? It finds the impact is insignificant. Even if it is significant, cormorant predation is a natural process, one of the many causes of natural mortality that results in such low survival from smolt to adult. Are you trying to deflect from the sea lice issue by blaming cormorants now?

no, it is just an interesting piece of reaserch that other people might be interested in.
