Results of a Bigmouth Buffalo Fry to Fingerling Feeding Demonstration in Harbin
Region: Northeast AsiaDownload
A feeding demonstration was conducted in Harbin in 1999 to demonstrate the advantages of ASA’s 80:20 pond technology and soy-based diets for producing bigmouth buffalo fingerlings. Bigmouth buffalo fry with an average weight of 0.5 g were stocked in two 7-mu ponds in Harbin in May and fed soy-based feeds for 106 days between June and September. The fry grew from 0.5 g to 60 g during this period, with an average FCR of 0.93:1. Net production averaged 244 kg/mu of bigmouth buffalo fingerlings and 62 kg/mu of silver carp fingerlings. Average survival for bigmouth buffalo was 83%. Net economic return was RMB 4,108/mu, with a 114% return to investment. The trial successfully demonstrated the value of the 80:20 technology and both the production and economic advantages of soy-based aquafeeds.
