A Study on the Productivity Comparison of Red Seabream (Pagrus major) in Brass Nets and Fiber Nets for Offshore Sea Cages
This study aimed to investigate the productivity of red seabream (Pagrus major) raised in brass net cages and fiber net cages installed in the offshore sea with a depth of more than 35 meters. The weight gain (WG), daily growth rate (SGR), feed coefficient ratio (FCR), and survival rate (SR) of red seabream were calculated to compare the productivity of a brass net cage and a fiber net cage. The productivity of red seabream was calculated by giving weight gain (WG), feed efficienct ratio, and survival rate of 50%, 30%, and 20% weights, respectively. The growth rate, feed efficienct ratio, and survival rate of red seabream were higher in the brass net cage than in the fiber net cage, and the productivity was improved by 34.7% (P<0.05).
