Figure 6
A radar chart illustrating the comprehensive nutritional evaluation of isopod meal, krill meal and fishmeal. Factors of ΣFAA/ΣAA(%),ΣEAA/ΣAA(%), EAAI andΣPUFA were scored based on the actual values from Tables 2, 3 and 4. For other two factors, three food materials are ranked based on the top rank having the highest value in the number of parameters, followed by the second and third respectively. For example, isopod substrate has six highest parameters in the mineral category, followed by krill with two and fishmeal one (Table 6), so they are ranked first, second and third respectively. To facilitate comparison with other factors in the radar chart, numbers "50", "40", "30" were assigned to the first, second and third ranked materials respectively.
