Many studies have sought to improve the digestibility and nutritive value of plant
feedstuffs by thermal treatment methods (Barrows et al. 2007), and thus in the present
study, autoclaved Ulva meal was studied in comparison with raw Ulva meal. The growth
performance of fish fed diets containing 10 % autoclaved Ulva meal (group AU10) was
significantly lower than that of fish fed 10 % raw Ulva meal (RU10); however, the performance
was not significantly different to the control. To the authors’ knowledge, there is
no information regarding the effects of autoclaved Ulva meal with respect to growth
performance of fish.
