A two-stage feeding trial was conducted near Haikou, Hainan Province, to evaluate fry to market growth performance of pangasius catfish using the ASA 80:20 pond production model and ASA soymeal-based feeds. In the first stage, juvenile fish were stocked in three, 2.5-mu (0.17-ha) ponds at a density of 3,000 pangasius catfish and 1,000 silver carp per mu (45,000 catfish and 15,000 silver carp per hectare). Pangasius catfish grew from 0.1 g to an average weight of 190 g per fish in 103 days of feeding, with an average FCR of 1.10:1. At fish size 190 g, the fish wererestocked at 700 pangasius catfish and 100 silver carp fingerlings per mu (10,500 catfish and 1,500 silver carp per hectare). Pangasius catfish grew from 190 g to an average weight of 880 g in 78 days, with an average FCR of 1.17:1. Total production time from fry (0.1-g) to market size (880 g) was 181 days. Pangasius catfish demonstrated excellent growth performance and feed conversion efficiency with the ASA soymeal-based feeds and 80:20 production technology throughout the production cycle. Harvested pangasius catfish were uniform in size with good body color and conformation.
