Spring was in the air on March 28th when
the time had come to release the alevins hatched at the Stronsay
School. The island was bathed in sunshine and the surface of the Meikle
Water was hardly broken by a gentle breeze from the east.
The 200 odd young trout hatched at the Stronsay
School were carried in a basin to the edge of the loch and then
transferred into plastic pouches to allow every pupil to release a dozen
fish each.
It was a good opportunity to learn about the
wildlife with which our trout would be sharing their new habitat: we
realised that the tiny alevins would need to be extra careful as many
predators such as mergansers, herons, cormorants, eels, otters and even
some of the bigger trout wouldn’t mind a little fishy snack! Our alevins
would have a more modest diet for the first year, consisting mainly of
daphnia, midges at various stages of development, freshwater shrimps and
insects.
Pupils gently released the fry in the vicinity of
weed beds to provide them with enough cover from predators, after
checking the loch water temperature (3⁰C) was as close as possible to
the water in which the alevins had been transported (4⁰C), in order to
avoid thermal shock.
A big thank you to Mrs. Evans who accompanied the
children and also to Steve, our janitor who supervised the pupils’
visits to our hatchery on a daily basis over the last couple of months.
