Feed Particle Size Requirements for Crucian Carp Fry

The American Soybean Association (ASA), in cooperation with the Zhejiang Freshwater Fisheries Research Institute (ZFFRI), conducted a study in 1999 to identify the feed particle size requirements for post swim-up stage crucian carp fry. The study had three objectives: 1) determine the feed particle size requirements of crucian carp fry >2.0 cm in total length; 2) determine at what size crucian carp are capable of ingesting a 1.5-mm extruded feed pellet; and 3) formulate feed size recommendations for fish farmers who are producing crucian carp fingerlings using feed-based production technologies. Results of the study are presented in this paper.
