This study investigated the basic biology as well as vital statistics of the Sakura shrimp, Sergia lucens in the southwestern coast of Taiwan. The research includes length-weight relationship, spawning season, sex ratio and Von Bertalanffy equation. All sample had found partly grown eggs. The greatest spawn in January and July. It is possible that one population in the fishing area. Analysis of Covariance(ANCOVA) on the relationship between length and weight shows that male and female has the similar growth rate; but male shrimp appeared to be heavier than female for about 0.0217 g. There are more female than male in fishing area, and the ratio increase toward large size group. The growth rate of Sergia lucens is allometric. Result from morphometric study as well as fluctuation in GSI shows that the Sergested shrimp of the southwestern Taiwan can be classified as belonging to one single population but with the possible existence of two spawning subgroups. Analysis on length frequency distribution computer package, FiSAT, showed that total mortality and natural mortality was equal to 7.86 and 5.02, respectively.
