The experiment was performed between 01 April 2002 and 01 January 2002. Known five different culture techniques of G. verrucosa were applied at the fish cages. These are culturing the algae at bottom by tying the thalli to the natural substratums, culturing the algae at the bottom in different mesh-size net-bags, culturing the algae on the ropes near the fish cages, culturing the algae on the ropes in the fish cages and culturing the algae in the net-bags near the fish cages. During the study biomass values and water quality parameters were measured and recorded. From the result of this study, the best culture technique was determined as culturing the algae in the net-bags near the fish cages. The highest spesific growth rate (5.8%/day) in November and December and the lowest spesific growth rate (-9.9%/day) in July were calculated.trinfo:eu-repo/semantics/closedAccessGracilaria verrucosared macroalgaeculture techniquesmarine fish cagesintegreted systemsArticle23305309N/AWOS:000440353500028
