- Fluidized bed filters are rapidly becoming the primary source of biological filtration in many modern aquaculture systems, replacing the less efficient trickle filters now in service.
- While trickle filters and fluidized beds both rely upon the same species of bacteria for ammonia and nitrite removal, it's how the two filters operate that sets them apart.
- It's very helpful to remember that in biological filtration, it's actually the bacteria that do the work; the filter itself only provides a suitable "home" for the bacteria to colonize.
- Trickle filters can best be described as open containers filled with various forms of solid media.
- As water enters the top of the filter, it drains down through this media in a random, cascading fashion.
- Since the media is stationary, it relies upon the changing water currents to keep the bacterial surface area moist.
- Fluidized bed filters, on the other hand, are flooded cylinders or tanks, partially filled with a granular media, such as white quartz.
- Water upflows through this media bed, causing it to expand and fluidize.
- The large number of bacteria that colonize this expanded media serve to remove the nutrients that are present in the flowing water.
- What results is a highly efficient filter bed that is no longer solidly packed, but is in dynamic motion.
- It is this combination that is the key to our QuikSand Filter's success.

- Rotifers are small (100-300 micron) zooplankton that exist in freshwater, brackish, and marine environments.
- Rotifers feed on microalgae and are consumed by a wide variety of fish, shellfish, corals, and other filter feeding organism.
- Rotifers are used extensively in aquaculture and aquariums because of their super high reproductive rates (doubling or better every 24 hours).
- Under optimal conditions a rotifer culture will double in volume every day.
- The life span of a marine rotifer is 7 to 12 days.
- They have very high metabolisms and empty their guts and need to eat every 4 hours.

- This complete system was developed, manufactured and marketed by Scubla Aquaculture based in Italy.
- They offers consist of manufacture, design and install of complete fish farming systems.
- Simply supply or complete package deals.
- Often hatchery is the most important component of an aquaculture plant, and guarantees the success of following stages.
- Scubla small-scale hatcheries are capable of rearing millions of larvae or fingerlings in one year.
- They can equally be used well in small farms, in large land-based fisheries, in fish cages systems alike.
- Scubla Aquaculture services also include training program for personnel, as a part of its management package.

- This simple and nice product supplied by Alternative Aquaculture, Lofthouse.
- This conical hatching jars was fabricated in clear plastic.
- Available in 2 sizes.
- Ideal for the incubation and hatching of both fish eggs and brine shrimp.
- Can be made in a variety of sizes to suit an individuals requirements.
- The hatching jars have an integrated spout at the top to allow the water/hatchlings to swim out into the hatching tanks.
- Easy to regulate the water flow precisely to suit the stage of development the eggs and to check them for any signs of infection.
- Picture of the product is shown below.
