The three Lancashire hatcheries were all doing well. At Brabin’s and St Leonard’s schools the eggs had all hatched. The alevins were mainly keeping to the gravel with a very occasional venture to the top of the water by one fish. The tanks were still wrapped with the reflective insulation to keep them cool.

At Thorneyholme the eggs had not yet hatched. This is thought to be because the water had been kept at 7oC through the half-term holiday. The thermostat was turned up by a couple of degrees, which would encourage the eggs to develop

At St Leonard’s the tank is situated in the year 1 & 2 classroom but the whole school is taking an interest. The children had been fascinated to see the eyes of the fish through the translucent eggs. They noticed that their eyes got bigger and bigger before the alevins eventually hatched out.
