Production of Red Drum in Near-Shore Ocean Cages: Results of a Feeding Demonstration in Quanzhou, China
Region: Northeast AsiaDownload
The growth performance of red drum (Sciaenops ocellatus) was evaluated in an ASA coastal cage trial in Quanzhou, China. Red drum were stocked at 312.5 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. Red drum grew from 14 g to 232 g in 103 days, with an average FCR of 1.54:1. Average fish survival was 73%. High mortality early in the trial and strong coastal currents required modifications to trial implementation and construction of the cage frames.
