== Using catfish to eat sewage ==
 
:''Based on comments posted by [[User:Chriswaterguy|Chriswaterguy]] (under the username Singkong2005) to [[Wikipedia:Talk:Catfish#Using catfish in septic tanks.]])''
 
Catfish are used in septic tanks in Indonesia, to eat the waste and prevent the tank from filling up with solids too quickly. I can't find a better source, so I'll just offer these links for now, and hope that someone comes up with a source. I might try and research and (co-)author a journal article on it this year (2007), which would then be a valid source.

Chriswaterguy's comment: [http://vasco-pyjama.livejournal.com/188455.html?thread=3648295 An Indonesian's comment on catfish in septic tanks]
 
The [[Wikipedia:id:Lele|Indonesian Wikipedia article on catfish]] mentions that freshwater catfish are used to remove impurities from water; it states that catfish used in the way must be cleansed before eating, by being placed in flowing water. (The article doesn't state how long for, or just how much this improves the taste & safety).
 
'''Suggested projects''':
* How efficient are catfish at processing sewage, compared to other processes (such as septic tanks, or activated sludge)? Would they be of use in [[municipal sewage treatment]]?{{sp}}
* Have they been (or can they be) used in a {{WP|treatment pond}}?{{sp}}
