Morphological Characteristics and Life History of the Chili Fish, Cultriculus eigenmanni(Jordan et Metz) Ⅱ. On the conditions effecting body length, body weight and fatness

A total of 378 Chili fish were randomly sampled at 4 locations including Mangyong reservoir, Oehang, Osan and Rapo water-way in the vicinity of Kunsan from June, 1983 to October, 1984 in order to investigate allometry according to their habitat and sex. The body weight and fatness conditions against the mean body length of the specimens from Rapo water-way were remarkably decreasing. And this result seems to be caused by seasonal difference. The relationships between total length and body weight are expressed, W=0.0116 L2.84795 : Oehang, Mangyung and Osan, W=0.00507 L3.06155 : Rapo. Considerable significance is recognized in these equations. Nevertheless, the significant difference is not found between location and sex in the same period.
