Aquaculture is more commonly referred to as fish farming, and this practice has been used for growing food in the form of seafood. The reason such long gaps are allowed in this method is that it helps feed large number of people. But keeping fish in small places can lead to dirty water if not wary and nicely tidy. On the upside, there are some functions aquaculture biofilters can perform to maintain water health for fish at all times!
In fish farms, aquaculture biofilters are an integral part. They keep the water clean so that it is suitable for fish to grow and thrive. A Biofilter; Just like the filters you would use to kill your city water (more on this later) these biofilters work in an identical manner other than they do much more then bring out impurities. This waste can be the fish poop, uneaten leftover food or any other nasty stuff which can contaminate water. In layman's terms, the biofilters essentially act like a sponge that natural cleans out all duck poo and stuff to keep the water clear safe for it fish!
When fish do their number twos in there, and ammonia is released into the water. Fish pee is toxic, and fish always want to get rid of it. The saving grace, however, is that biofilter has got friendly bacteria doing great things to convert ammonia into less offensive compounds. Bacteria transform ammonia into nitrite and then into nitrate. Nitrate is not only safe for the fish but can even be used by plants as food. All this process is called nitrogen cycle and necessary to keep the water in good condition/suitable for life.
Emerging technology may be helping biofilter perform even better. A biofilter is a type of trickling filter for example. These filters are installed in fish farms at the bottom of which special filter materials flow through water. That set up will give them more room to grow bacteria and they can do their duty properly of cleaning the water.
Moving bed biofilter is third another type of Biofilter. This is done by small plastic beads that are agitated in a dump tank of water. It allows more room for the beneficial bacteria to propagate and further decay the poisons you are trying so hard to remove! These hi-tech devices will provide feed to fish and keep the water clean.
Before we discuss making a good functioning biofilter, it is best that you first understand how they work. Biofilters need to be designed specifically for the fish farming they are used in. Mainly take into account the number of fish with how big your tank/pond is and what type or species you are breeding. Some of these factors are, indeed, important to maintain an operational biofilter.
Biofilters are an essential part in protecting and keeping our waterways clean. By using biofilters, the fish waste that is deposited directly into water bodies by commercial fishing is minimized. This keeps the field clean and devoid of diseases to are able to your fish.
