| Abstract: | Big mouth buffalo,Ictiobus cyprinellus ,is endemic to North America.As an important species for aquaculture,it was introduced to China in 1994.The researches on this fish species mostly focused on fish culture and diseases.The food and feeding habits of big mouth buffalo fingerlings was studied from May to October 2000.The results showed that big mouth buffalo fingerlings had clear food selectivity in feeding,and preferred to bigger zooplankton species.With the growth of the fish,the selected food size would also increase.It was not evident that zooplankton species and their escape ability had influence on the food and feeding habits of big mouth buffalo fingerlings.The food relations among Ictiobus cyprinellus,Hypophthalmichthys molitrix and Aristichthys nobilis were also discussed. |
