Effects of Different Pollen Supplemental Levels in Feed on Growth of Pseudorasbora Parva

The feeding experiment in Pseudorasbora parva was conducted in aquarium within doors for 40 days by using different pollen supplemental level (0.5%-9%) feed. The results showed that: the growth, capability of digest and decomposition of Pseudorasbora parva were enhanced after adding suitable quantity pollen in feed. The suitable supplemental quantity of corn pollen was 0.5% and 1%. Under this condition, fishes got relatively better growth rate and the cost for feed was reduced.
