Rising feed prices have forced more than 30% of catfish breeders in Vietnam's Cuu Long delta to shut their businesses, Vietnam News quoted Vietnam Association of Seafood Exporters and Producers in a report.
Pig and poultry breeders also suffered losses for the same reason.
Experts said livestock breeders had expanded production by 15-20% in 2008, while the area for catfish and shrimp breeding in the delta reduced sharply.
