The collection of organisms, such as algae and bacteria, that live on the surface of submerged plants and other underwater objects.

[New Latin, from Greek periphuton, from neuter sing. of periphutos, planted all over, from periphuein, to grow around, cling to : peri-, peri- + phuein, to grow; see bheuə- in Indo-European roots.]


(Environmental Science) aquatic organisms, such as certain algae, that live attached to rocks or other surfaces
[C20: from Greek, from peri- + phutos, from phuein to grow]


(pəˈrɪf ɪˌtɒn)

the community of tiny organisms, as hydras and snails, that lives on the tops of rooted aquatic plants.
[1940–45; probably peri- + Greek phŷton plant, -phyte, on the model of plankton]

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.
2009) studied the effect of the addition of tilapia and substrates for periphyton development on ecology, production and economic performance in the rates of C/N, in a freshwater prawn (Macrobrachium rosenbergii) farm.
Sampling periphyton tissue for laboratory analyses and calculation of TN:TP ratios in the filamentous green algae species that dominate algal biomass in the Rio Ruidoso upstream and downstream from the WWTP.
They are characterized by a regime where short-term events capable of transporting bedload and removing periphyton occur several times each year (Scatena & Gutpa 2012).
