The effects of fish oil (FO) supplementation and the dietary replacement of FO with flaxseed oil (FlaxO) and canola oil (CO) on the growth of cultured abalone was investigated. The study involved three growth experiments: (E1) diets containing 0.5, 1.0, 1.5, 2.0 and 2.5% of FO, respectively; (E2) diets in which FO was serially replaced by 25, 50, 75 and 100% FlaxO, respectively; and (E3) diets in which FO was serially replaced by 25, 50, 75 and 100% CO, respectively.
In Experiment 1, abalone fed a diet supplemented with 1.5% FO showed a significantly higher (121.2 ± 1.1 mg day−1) daily growth rate of weight (DGRw) compared to control (70.1 ± 1.71 mg day−1). In Experiment 2, abalone fed 1.5% FO diet and diets containing 25–75% FlaxO showed no significant differences in DGRw. The diet containing 100% FlaxO showed significantly lower (63.3 ± 6.7 mg day−1) DGRw. In Experiment 3, abalone fed diets containing 25% and 50% CO showed similar DGRw as those fed a 1.5% FO diet. The diet containing 75% and 100% CO showed significantly lower (63.7 ± 5.0 to 95.4 ± 5.1 mg day−1) DGRw.
Supplementation with 1.5% of dietary FO can improve growth performance in cultured abalone. It is feasible to replace 75% of dietary FO with FlaxO and 50% of dietary FO with CO, without negative effect on growth performance.
