The growth performance of brown croaker (Miichythys miiuy) was evaluated in an ASA coastal cage trial in Dongtou, China. Croaker were stocked at 250 fish per m3 in three replicate cages of size 6.4-m3 and fed to satiation twice daily with the ASA extruded marine fish fingerling and growout feeds. Brown croaker grew from 10 g to 213 g in 117 days, with an average FCR of 2.0:1. Average fish survival was 51.7%. High mortality early in the trial and strong tidal currents required modifications to trial implementation and construction of the cage frames.
