The provision of floating annular covers to conventional tangential-flow rearing tanks significantly increased the growth rate of underyearling Atlantic salmon during the period July–November. This increased the proportion of potential 1-year-old smolts from 22% to 38% of the population (P < 0.001). Salmon without access to overhead cover grew slowly and showed haematological signs of a chronic stress response (thrombocytopenia and lymphocytopenia). Mortality rates and the incidence of disease… CONTINUE READING
