Periphyton

 

freshwater organisms that live attached to the underwater parts of riverboats, beacons, piers, and other man-made structures. The term was proposed by the Soviet hydrobiologist A. L. Bening in 1924. It was subsequently used to designate the overgrowth of marine hydroengineering structures with organisms. At present, the term is almost never used and has been replaced by the term “fouling.”

Even though excreta of three pigs may just be sufficient to fertilize a pond of 1,000 [m.sup.2] in one production cycle, more than 30 pigs [ha.sup.-1] pond is recommended [45] to ensure sufficient supply of biofloc community for pond microbial synthesis and periphyton development [46].
