Feed particle size requirements for Crucian carp fry

Results of ASA/China 1999 Feeding Trial 35-99-61
Feed particle size requirements for crucian carp of 2-cm to 7-cm total length were determined in a joint study by ASA and the Zhejiang Freshwater Fisheries Research Institute in Huzhou, China. Results were used to formulate feed size recommendations for fish farmers producing crucian carp using feed-based production technologies. Crumble feeds of size 0.5-mm and 1.0-mm are recommended for fry of 2-cm and 3-cm total length, respectively. Crucian carp fry can be weaned to a 1.5-mm extruded pellet at 5-cm total length.

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.
