The protein content of the three seaweeds used in
this trial was below that level. The nutritive value of the algae may
explain the feed utilization profile. The FCE of abalone fed
G. lemaneiformis was significantly higher than the other diets, most
likely because of its nutrition profile (i.e., lower moisture and higher
protein content). This explains why the increase in shell length of
abalone fed G. lemaneiformis was similar to that of abalone fed kelp,
even though feed intake was lower
