摘要

An artificial fish spawning ground made of artificial sargasso attached to ropes is provided to create a spawning area for fish and to increase fish spawning rate and hatching rate. An artificial fish spawning ground comprises: a sargasso(11) used as a substrate made of artificial marine algae; an artificial sargasso(12); a spawning structure formed of connection ropes(15) where the sargasso and artificial sargasso are connected in a radial direction, and floats(20) being attached to the top of the connection ropes, and shackles for connection and fixation; a support rope(50) to which the shackles are connected and fixed; and a structural support rope including plural circular stones(40) and anchors(60) attached to the circumference of the support rope.
