The present invention relates to an aquaculture ship which treats a nutrient or an active treatment agent for the growth of marine algae cultured on a rope, collects the grown marine algae, and performs overall management on a marine algae aquaculture farm. More specifically, the present invention relates to a marine algae aquaculture ship which includes an outer surface unit in a ship shape for treating cultured algae with a nutrient or an active treatment agent or collecting the cultured algae, and a conveyor unit formed of a conveyor means on the outer surface unit. The marine algae aquaculture ship according to the present invention simply immerses Sargassum fusiforme in treatment water containing a nutrient or an active treatment agent, which is necessary for the growth of marine algae, while moving a culturing rope for growing the marine algae on a managing ship using a conveyor. Therefore, the marine algae aquaculture ship can reduce the costs and time by being directly put into a culturing farm； can adjust the operation time by using the conveyor, thereby controlling the immersing time as needed； removes harmful organisms or foreign substances attached to Sargassum fusiforme by workers using hide panels； recirculate and uses the treatment water containing the nutrient or the active treatment agent； sprays and immerses the treatment water containing the nutrient or the active treatment agent using a nutrient injection means from the upper side of the Sargassum fusiforme toward the lower side so as to improve the immersion performance； and can easily perform the collection of the marine algae using the conveyor.본 발명은 로프에 양식되는 해조류의 생장을 위해 영양제 또는 활성처리제를 처리하거나, 생장된 해조류를 채취하며, 해조류 양식장 전반에 걸쳐 관리를 실시하는 양식선에 관한 것으로 보다 상세하게는 양식되는 해조류에 영양제 또는 활성처리제를 처리하거나 해조류를 채취하는 선박 형태의 외면부와 상기 외면부에 컨베이어 수단으로 이루어진 컨베이어부가 포함되는 해조류 양식선에 관한 것이다.본 발명에 의한 해조류 양식선은 해조류가 생장하고 있는 양식로프를 관리선 위에서 컨베이어를 이용하여 이동시키면서 해조류 생장에 필요한 영양제 또는 활성처리제가 포함된 처리수에 톳을 간편하게 침지시키고, 양식장에 바로 투입되어 비용 및 시간이 절약되고, 컨
