Figure 1: Mean weight gain (±SE) of Atlantic cod cultured in nylon and copper nets. Mean weights from replicates in each treatment were not significantly different (Kruskal-Wallis tests, P > 0.05) so all replicate weights within treatment were combined. There was no significant difference in mean weight (Unpaired t-test with Welch correction, P > 0.05) between fish raised in the copper alloy and Flexgard™ treated nylon cages. |
