significantly better (Pb0.05) than those fish fed the LO, OO or SO diets.
On the other hand, fish fed PO had a significantly lower fat deposition
rate (FDR) than FO fed fish, and a lower net fat utilisation (%NFU) than
all other treatments. The lipid efficiency ratio (LER) recorded in SO fed
fish was significantly lower (Pb0.05) than in fish fed the FO diet.
During the subsequent finishing period, fish gained an additional 50%
of their body weight (over 400% relative to the initial body weight) and
recorded a feed consumption of ~0.9% of their body weight with an FCR
of ~1 (Table 4). With the exception of dress-out percentage (DP%),
which was significantly lower in fish fed the SO diet compared to all
other treatments, no other statistically significant differences were
recorded with respect to any of the other growth and biometrical
parameters.
