Phenotype of salmon lice offsprings obtained after the LsRXR RNAi experiment. In the control group (A) normal developed nauplia II (a) and copepodids (c) are found. At day nine the exuviae from nauplia II (b) are found in large amounts. In the RNAi groups development is disrupted, either by disrupted hatching (Ba), or the nauplia are deformed (B b-f). We also observed nauplia arrested in their development to copepodids (Bg). In a very few cases apparently normal looking copepodids (Bi) or exuvia (Bh) were observed. The bar in the upper right corner is 0.1 mm long.
