Student Project Figures Figure 5 Figure 5. Boxplot showing the treatment effects of salinity on number of algae cells consumed•hour-1•oyster-1. ​Four salinity levels were used; 0ppt, 15ppt, 30ppt and 45ppt on S.glomerata (98mm ± 3mm). Each oyster was fed 1ml of an algae mix of 25% Nanno 3600, 25% Iso 1800, 25% Pavlova1800 and 25% TW1200. Optical density readings were taken at time 0 and after 3 hours. Salinity was found to have no significance on filtration rate. Solid black line represents Tukey HSD results. All boxes above line indicate no significant difference between treatments.  Figure 5 Figure 6
