The present invention provides a double buoyant fixed shore net buoy that has improved productivity and durability for environmentally friendly fixing fishing nets used in aquaculture and cage netting. The present invention provides the double buoyant fixed shore net buoy, comprising: an outer shell part made of a metal material in which rim ends of opposite surfaces of a first shell part and a second shell part are mutually sealed so as to form a first buoyancy space therein; and a rubber tube made of rubber material embedded inside the first buoyancy space, and having a second buoyancy space formed by having air injected and expanded therein.
양식 어업 및 가두리 정치망 등에 사용되는 어망을 친환경적으로 고정시키기 위해 생산성 및 내구성이 개선된 이중부력식 정치망 부표를 제공하기 위하여, 본 발명은 내부에 제1부력공간이 형성되도록, 대향면이 개구된 중공으로 각각 형성된 제1쉘부와 제2쉘부의대향면측 테두리 단부가 상호 밀봉 결합되는 금속 재질의 외부쉘부; 및 상기 제1부력공간의 내부에 내장되되, 내부에 공기가 주입 및 팽창되어 제2부력공간이 형성되는 고무 재질의 고무튜브를 포함하는 이중부력식 정치망 부표를 제공한다.
