A.D.A.A. Visit to the Don Hatchery 2004
I thought I would present the pictures I took of the visit in the form of a series showing the process Jim and his team follow to end up with trays of salmon, brown and sea trout eggs to enhance future generations and to keep us anglers happy people.
The Catch Process
Preparation of Fish
Stripping the Fish
Once the fish are ready they are carefully removed one by one. The hen fish first, and gently the the eggs are stripped into clean containers which have to be completely dry. If water is present at this stage the eggs will 'seal' prematurely and will not be fertilised. Next the 'cock' fish is stripped of its milt into the same container which is then swirled gently to mix both eggs and milt at which time 'life begins'. After 10 minutes or so water is introduced so the eggs seal and to clean them.
The fertilised eggs are then transferred to clean trays to start their steady growth over the winter. Care has to be taken with water quality, its taken from 500 yards away upstream, and filtered a number of times because of the silt from winter floods.
The eggs grow steadily through the winter with the first signs being the black spots of the eyes appearing
The work of the Don Board must be commended for the effort that is put into put into the production of over 750,000 eggs of salmon, brown trout and sea-trout annually at the hatchery. The hatchery, which is supported by donation, brings the alevin on and distribute these to over 35 locations between May and September.. On behalf of the ADAA thanks once again to Jim, Stephen, Michael and Leslie for their help.
