| Abstract: | The paper discuss the feeding habits, growth and breeding of crucian carp of Baiyangdian Lake after restoring water. The major food of the crucian carp are bacillariophyta, cladocera and water bundle plant. It can be divide into five age groups, the average plumpness is 3.1324, the growth of the Ⅱ-Ⅲ age groups are fastest and best. The mature coefficient of sexual gland is 4.293%-13.072%. |
