The babes in the growing on had been just a big sluggish on their food this week, not the normal tidal wave when the feed went in, and just the odd sign of a pec clamped in when they thought I wasn’t watching
Checked the water all Ok, slipped a couple out for scrapes during the week and these were clean.
Spent some time yesterday taking a few scrapes when I had the little Shiros out.. Took 7 slides of nothing then number 8 and bingo - 7 gill flukes on the slide..
Moral being when something is amiss keep searching for it.
