结果表明，鲤鱼主要摄食浮游植物，而青鱼摄食大量浮游动物、碎屑和浮游植物。鲤鱼过滤的颗粒大小(17-3000微米)大于鲤鱼过滤的颗粒(8-100微米)。人工饲料很容易被鲟鱼摄取，但不能被鲤鱼摄取。受精池和人工饲料池塘的生长差异不显著。添加人工饲料可显著提高鲟鱼的生长速度。网箱中生长较快的网箱鲤鱼，其生长速度明显快于鲟鱼。
Analysis of intestinal contents of silver carp (H. molitrix) and bighead carp (A. nobilis) showed that silver carp consumed primarily phytoplankton while bighead carp consumed large quantities of zooplankton, detritus and phytoplankton. The size of particles filtered by the bighead carp was larger (17-3000 .mu.m) than that filtered by silver carp (8-100 .mu.m). Artificial feed was readily consumed by bighead carp but not by silver carp. No growth difference was indicated for silver carp in fertilized ponds and ponds receiving artificial feed. Growth of bighead carp increased substantially with the addition of artificial feed. Silver carp grew more rapidly in cages than bighead carp.
