摘要	Sargassum horneri (Turner) C. Agardh is used to restore, create, and recreate seaweed beds along the coastlines of East Asia. Drag produced by waves is a bulk force that can detach thalli from substrata during the early growth stages from substrata. In this study we measured drag forces on small S. humeri thalli (10-40 cm long). Unidirectional steady flow was controlled from 20 to 130 cm s(-1) in increments of 10 cm s(-1) in a recirculating water tank. Drag force on individuals ranged from similar to 0.3 N to similar to 3 N. Drag (F-drag) and water velocity (U) produced the following exponential empirical approximations: F-drag = 0.0168 x U-0.8925. The drag coefficient (Cd) was plotted as a function of Reynolds number (Re) as follows: Cd = 4744.7 x Re-0.93. Cd converged to 0.037 at Re of 10(5-6) suggesting that small thalli exhibit optimal morphological adaptations to withstand high current speeds.
