Abstract:The samples of 1019 young adult red-fin pargo, Parargyrops edita Tanaka,caught by double draggers in the South FUjian and Taiwan Bank fishing ground were collected monthly from December 1978 to November 1979. Scales are taken from the middle between the 5-10th dorsal spices and the left lateral line used to determine the age and the growth rates of the fish. The true annuli of the scales are shown as discontinuous or broken circuli on the scales and are formed annually. The ago groups are normally distinguishable in length-frequency distribution. Data on the rates of marginal increment of the scales show that the time of annulus formation relating to its reprodutive activity occurs chiefly during March to April. The relationship between the body length L (mm) and the scale xadius R (mm) is expressed to be R=0.12229+0.02108L, the length-a0eight relationship formulas are calculated to be W=3 .2851 X 10-5L3.0299,W‘=4.5821X 10-5L2.9723, where W and W' represent net body w eight (g) and total body weight (g) respectively. The result of length back-calculation indicates the absence of the R,osa Lee phenomenon. According to the mean observed body lengths for each age group, Walford's plot method is used to compute the optimal parameter L∞,The growth parameters are:L∞=248mm, W∞=592g, k=0 .17, t0=一1.24, and the senile inflection point tr=5.08 years (approximate to TV age group).The growth curves drawn by von Bertalauffy growth equation show no significant difference between the mean calculated lengths (or weights) and the mean observed lengths (or weights)Red--fin pargo zuatures at one year old and the growth rates decrease after the end of adult stage. Age groups 0 and Ⅰ are predominant in commercial catches, the fish older than Ⅳ group are not common in catches. The minimum catchable age group and size of this fish may be suggested to be Ⅰ age group, 110 mm in length and 50 grams in weight.
