Brown Seaweed (Sargassum Fulvellum) Inclusion in Diets With Fishmeal Partially Replaced with Soy Protein Concentrate for Japanese Flounder (Paralichthys Olivaceus) Juveniles

Soy protein concentrate (SPC) rarely replaces fishmeal (FM) completely in marine finfish diets without eliciting adverse effects on fish performances. The inclusion of brown seaweed (Sargassum fulvellum) could alleviate the negative effects linked to high SPC dietary inclusion. In the current study;...

The inclusion of brown seaweed (Sargassum fulvellum) could alleviate the negative effects linked to high SPC dietary inclusion. In the current study; the dietary effects of S. fulvellum inclusion in diets for Japanese flounder (Paralichthys olivaceus) in which FM was partially replaced with SPC were evaluated. A FM-based positive control (Con+) diet with FM protein partially replaced with SPC protein (Con-) was supplemented with S. fulvellum at levels of 30; 60 and 90 g/kg to formulate SF3; SF6 and SF9 diets; respectively. The five diets were fed to fish (0.52 g) in triplicate groups up to apparent satiety for 56 days. The dietary brown seaweed significantly increased (p < .05) growth performance; showing significantly higher per cent weight gain (p < .05) and specific growth rate in fish fed SF6 and SF9 compared to other treatments.

Brown Seaweed (Sargassum Fulvellum) Inclusion in Diets With Fishmeal Partially Replaced with Soy Protein Concentrate for Japanese Flounder (Paralichthys Olivaceus) Juveniles
