Beyond their nutritional value, bioflocs and periphyton are also capable to remove nitrogen, phosphorus and toxic compounds from the water (Azim & Little, 2008).
Two possible ways to increase the aquaculture yield with environmental sustainability are (1) use of underwater substrates for periphyton and (2) correction of the C: N ratio of water (Avnimelech, 2006).
Higher periphyton biomasses, for example, are usually found in the Ivinhema River, which carries more phosphate than the Parana River (Leandrini, Fonseca, & Rodrigues, 2008).
It includes identification keys to algae, periphyton, protozoa, freshwater invertebrates, and plankton, and discussion of catchments and their nutrients and organic matter; the ecological development of ponds and lakes; food webs and structures in ponds; problems, such as acid rain and loss of nutrients; and future issues, such as water supply, food security, and climate change.
The GB has a dark coloration, large surface, soft texture, and high porosity, which may improve the space available for periphyton development.
