¹Experimental diets: CON = a standard grower diet, SMS0 = CON containing 150 g/kg brown seaweed without oyster mushroom spawn inoculation, SMS20 = CON containing 150 g/kg of brown seaweed substrate after inoculating with 20% oyster mushroom spawn, SMS30 = CON containing 150 g/kg of brown seaweed substrate after inoculating with 30% oyster mushroom spawn, SMS40 = CON containing 150 g/kg of brown seaweed substrate after inoculating with 40% oyster mushroom spawn, and SMS50 = CON containing 150 g/kg of brown seaweed substrate after inoculating with 50% oyster mushroom spawn. ²Parameters: temp, temperature; L*, lightness; a*, redness; b*, yellowness; WHC, water-holding capacity. ³SEM = standard error of the mean.
