Effect of brown seaweeds on Pacific white shrimp growth performance, gut morphology, digestive enzymes activity and resistance to white spot virus

This work aimed to evaluate growth performance, gut histology, digestive enzyme activity and resistance to challenge with White Spot Syndrome Virus (WSSV) of Litopenaeus vannamei fed 0.5, 2 and 4% of dry biomass from the brown seaweeds Sargassum filipendula and Undaria pinnatifida. Shrimp (4.23 ± 0.15 g) were reared for 38 days in 800 L tanks (40 animals per tank) in triplicate under constant aeration (O2 > 5 mg L−1), controlled temperature...
