Abstract

Growth of Ammodytes personatus was investigated based on the specimens collected in the costal waters of Shinsudo, Sacheon from March 20 to December 14, 1988. Age determination based on otolith. The rings in the otolith were used as the basis for age annulus. The time of ring formation was estimated to one time per year in May far 1st ring group and March for 2nd ring group. The spawning season peaked in December. It takes approximately 16 months for the first ring and 11 months for the second ring to form in the otolith. The opaque zone was formed and marked over summer at 1st ring group and spawning mark at 2nd ring group. The relationship between the total length(TL) and otolith radius(R), and body weight(BW) were represented respectively as follows: TL=29.17+182.9R, BW=$4.9{\times}10^{-8}TL^{3.9587}$. Von Bertalanffy growth model is $TL_t$ = 177.273 ($1_e^{-0.040(t+7.332)}$), Robertson growth model is $TL_t=\frac{150.275}{1+2.085e^{-0.099t}}$ and Gompertz growth model is $TL_t=157.551e^{-1.214exp(-0.069t)}$.

경상남도 사천시 신수도 연안에 서식하는 까나리의 성장 상태를 파악하기 위해 1988년 3월 20일부터 12월 14일까지 9회 채집하였다. 연령형질인 이석에 나타난 윤문은 연 1회 형성되었고, 형성시기는 제 1륜군은 5월에, 제 2륜군은 3월에 년(年) 1회 형성되었으며, 윤문 형성 원인은 산란에 의한 것으로 나타났다. 산란기는 12월이므로 초륜이 형성되는 데는 약 16개월이 소요되었고, 초륜 이후 2륜군이 형성되는데는 약 11개월이 소요되었다. 전장 (TL)과 이석경(R) 간에는 TL= 182.9R+29.17이었고, 전장(TL)과 체중( BW) 간에는 BW = $4.90{\times}10^{-8}TL^{3.9587}$로 나타났으며, von Bertalanffy 성장식은 $TL_t=177.273(1-e^{-0.040(t+7.332)}$, Robertson 성장식은 $TL_t=\frac{150.275}{1+2.085e^{-0.999t}}$이고, Gompertz 성장식은 $TL_t=157.551e^{-1.214exp(-0.069t)}$이었다.
