Sontakke et al. [fifty eight] also reported a big lessen in plasma glucose in milkfish, Chanos chanos, cultured with biofloc designed of varied carbon sources which include sorghum, potato, yam, and glucose, and Kim et al. [27] showed a major minimize in plasma glucose in olive flounder, Paralichthys olivaceus, cultured with biofloc, equally suggesting this decrease implies that the fish raised with biofloc experienced less physiological tension than controls. Most reports have reported lower plasma glucose concentrations in fish lifted with biofloc, but some studies have reported a boost, suggesting that the biofloc surroundings may perhaps act as a stressor with regards to the species and ailments.
