At depths of 20-40 m the species constitute about 13 percent of the total catch. Relatively small individuals were caught, with length ranging from 21-26 cm and a mean weight of 170 g. In the offshore part, i.e. at depth 70-75m, the abundance of Caranx rhonchus reached 99.2 percent of the total catch. The length of fish in this zone ranged from 27-37 cm (mean length 32.2 cm) and mean weight was 494 g".More info."Annexe 16.
