Effects of Bdellovibrio and Like Organisms on Survival and Growth Performance of Juvenile Turbot, Scophthalmus maximus
Abstract In this study, the impact of Bdellovibrio and like organisms (BALOs) on juvenile turbot rearing was investigated in a static water rearing system with weekly partial change of water. A 60‐d‐long rearing experiment showed that, compared with control, survival rate, percent weight gain, perce...
