| Summary: | Includes bibliographical references (leaves 91-111). The feasibility of growing red seaweed, Gracilaria gracilis (Gigartinales, Rhodophyta) in land-based culture systems was investigated in two Western Cape abalone farms i.e. Jacobsbaai Sea Products (JSP) and Irvin & Johnson (I&J) and large size culture tanks (I&J). All the tanks were stocked with at 2 kg m⁻² supplied with unfiltered seawater (24 and 4 volume exchanges d⁻¹) JSP and I&J, respectively. This study also tested the efficiency of G. gracilis as a biofiltering species as well as investigating the effectivenss and influence of nutrient-enriched seawater i.e. turbot and abalone effluent (JSP) and fertilized seawater and abalone effluent (I&J) on the growht of Gracilaria. |
