Table 5.
Mean total wet weight gain and dry matter production of Lytechinus variegatus feddiets with varying protein and carbohydrate levels, protein:energy ratios (P:E), total energy (TE), and protein:carbohydrate ratios (P:C). P:E represents mg of protein per kilocalorie. TE represents total dietary energy in calories per gram. P:C represents protein:carbohydrate ratio (mg mg-1).
| % Protein | % Carbohydrate | P:E (mg P kcal-1) | TE (cal g-1) | P:C | Final Wet Weight (g) | Wet Weight Gain (g) | Final Dry Weight (g) | Dry Matter Production (g) |
