Implication

Experiment reveals that replacing Undaria pinnatifida with Ulva australis or Saccharina japonica may enhance growth metrics in abalone, suggesting sustainable aquafeed options.

Key Points

Replacing Undaria pinnatifida with Ulva australis or Saccharina japonica improves growth rates in Pacific abalone.
Specific growth metrics were similar across various dietary replacements up to 75%, indicating potential benefits.
Laboratory analysis involved feeding abalone diets with varying levels of macroalgae over a 6-week period.
These findings support the use of alternative seaweeds in aquafeed, with feasibility for commercial abalone farming.
