See below the document submitted by Mr Jerome Vaughan and note how he so easily disassembles the EA guidelines and exposes their falibility when given proper expert scrutiny.

What’s this document about?
|
This guidance helps staff determine fish removal and fish
introduction applications to stock salmon, sea trout and brown trout derived
from local broodstock rearing schemes.

Disadvantages explained

Reference to Ferguson, 2007
“Population specific smolt development, migration and maturity schedules in
Atlantic salmon in a natural river environment”
Reference to Fraser, 2008
“Mixed evidence for reduced local adaptation in wild salmon resulting from
interbreeding with escaped farmed salmon: complexities in hybrid fitness”
|
It is not clear which papers are being referenced, the two provided
are all I was able to find. The Fraser 2008 paper does not deal with
hatcheries raising wild salmon, rather cross breeding of salmon escaped from
farms.
Please confirm which papers are being reference in this paragraph

Scheme consents
|
We will only consent schemes which give rise to less than 1% of any
component of a salmonid stock, since we believe that the risks involved in
such small interventions are negligible.
|
Restricting scheme sizes to this level is de minimis in relation to
the river and cannot be considered a true test of stocking efforts.
|
Please confirm how this document can claim any scientific basis to
its conclusion and policies if, it has chosen to only reference arguments and
data against stocking. If there is no scientific basis for support of
stocking, this should be explicitly stated.
If there are scientific papers providing support for stocking
programmes, why have these been neither discussed nor referenced?

Introduction
|
However, some accounts have emphasised the role of the hatchery
(Marshall, 1992; Carlton & Francis 1992; Carrick and Gray, 2001) while
others have suggested its role may be less important than natural processes (Champion,
1991; Environment Agency, 1997).
|
This account does not tally with the Papers produced by Natural
Resource Wales v.4: 10.3.14, which shows overwhelming
scientific support for Hatcheries (25-papers for 10-against)
|
Introduction Para 2
|
An objective description of the recovery, evaluating the influence of
the stocking programme and other factors, has never been carried out.
|
1. Objective
evaluations have been carried out and are referenced in the paragraph above
2. The
EA can hardly call itself objective given it has published its own paper in
1997 seeking to reduce the emphasis on the role of the hatchery
Please explain how such an absurd statement as this can be treated as
rational.

Basis of research
|
No formal monitoring of the Tyne stocking programme has been carried
out and this presents some difficulties in this evaluation.
|
If you haven’t got data you shouldn’t be carrying out a study, let
along basing a nationwide strategy on the findings
|
Basis of research
|
A further complication is several factors have been changing
simultaneously during the period of recovery, each having potential impacts
on its trajectory
|
OK, so no data and no baselines. Not a promising start for any
scientific investigation
|
|

|
Basis of research
|
2.
Exploration of long term rod catches…and the
timing of environmental improvements. These
are compared with some hypothetical recovery profiles that might be expected
under alternative scenarios.
|
My italics on this. So the report is going to base its findings on no
formal data from the hatchery programme and guesses as to what might have
happened? I fail to see how this can be considered logical.
|
Comment: I find I’ve reached page 6 of this report and, consider the
basis on which the report and logic underpinning it are presented to be
amateur in the extreme. This would be mildly amusing, were it not for the
fact, the findings and use of this report, are being used to justify
decisions which impact on a significant number of people.

Sentence 2
|
A comprehensive review of scientific research found that
hatchery-reared young salmon have a much lower survival rate than young wild
fish, and can harm existing wild salmon populations.
|
This is simply a lie. It is not supported by the survey of literature
produced by Natural Resources Wales v.4:
10.3.14
