Effect of predation of starfish, Asterias amurensis and Asterina pectinifera under different water temperature in the recirculating seawater vessel was conducted at the invertebrate culture laboratory of Yosu National University from February 1 to February 25, 2000. The highest activity of Asterias amurensis and Asterina pectinifera according to water temperature was obtained at 14℃ and 22℃. The average individual numbers of Anadara broughtonii predated by Asterias amurensis and Asterina pectinifera were 2.20 and 1.60 at 6℃, 3.60 and 2.00 at 10℃, 7.20 and 2.50 at 14℃, 3.40 and 6.80 at 22℃, 0.80 and 3.90 at 26℃, respectively.
