In view of the traditional method of counting fish spawns has many shortcomings，such as poor precision，
low efficiency and eggs damage． In order to cover the shortcomings，being helpful for follow-up work，two methods
of counting fish spawns based on image processing was proposed in this paper． Through the powerful image processing
function of Matlab software，putting up median filter，gray processing，binary processing and morphological operation
to the reading image dealt by Photoshop software． Then on the theory of connected graph counting and area
comparison，counting up the number of spawns，the degree of counting precision is higher than 95 which have
certain theoretical and practical value．
