Effect of bioreactor-grown biomass from Ganoderma lucidum mycelium on growth performance and physiological response of red hybrid tilapia (Oreochromis sp.) for sustainable aquaculture
Mushroom mycelial biomass is an alternative to unsustainable use of cash crops as feed in aquaculture systems. Lately, fish-feed mixtures enhanced with heterotrophic 1-m2-bioreactor-grown biomass from the mycelium of Ganoderma lucidum (MGL) were fed to red hybrid tilapia Oreochromis sp. (tilapia). M...

Mushroom mycelial biomass is an alternative to unsustainable use of cash crops as feed in aquaculture systems. Lately, fish-feed mixtures enhanced with heterotrophic 1-m2-bioreactor-grown biomass from the mycelium of Ganoderma lucidum (MGL) were fed to red hybrid tilapia Oreochromis sp. (tilapia). MGL biomass had high protein (32.2), carbohydrate (48.4) and fibre (13.8) content compared with other common fish-feed sources (fishmeal, soybean meal, rice bran and corn). Four experimental diets containing 0 (control), 5, 10 and 15 g/kg of MGL biomass respectively were randomly allocated to eight, 70-L tanks at 15 fish per tank with duplicate treatments. All diets were formulated to be isoenergetic (~ 19 kJ/g), and the fish were fed twice per day at 3 of their body weight ratio during the feeding trial, which lasted for 42 days.
