So why did RotoTank™ get involved with fish farming?
Fish farming involves raising fish commercially in tanks. Farmed fish for subsistence food has become popular in recent years as more people seek to provide a healthy source of protein. Fish farming can be done on a small scale in ponds, pools, or more recently designed fish tanks. RotoTank™ took note of this growing industry and started to produce affordable minimal maintenance tanks, which suit the startup farmer as well as the larger established farmers.

Why is water Temperature so important with RotoTank ™ Fish Breeding tanks?

If you cannot keep the water temperature at a constant twenty-two°C to twenty-five°C, day, and night for 365 days per year, you’re not going to see substantial growth in your fish, you should invest in a water heating system (electrical or solar), to achieve optimum water temperatures throughout the year.

RotoTank™ recommends Pumps and Filtration System for a fish breeding pond as follows

You will require a powerful water pump that will turn the volume of water in your tank at least once per hour; it would be best to have a centrifugal self-priming pump, though some submersible pumps will also do the job.

Every aquaculture system requires two types of filters

  • Mechanical Filter (Solid Separator)
  • Bio Filter

Bio Filters is the most important, as without them the ammonia generated by the fish would reach extremely high levels that would eventually kill them.

Why do you need Aeration in your RotoTank™ fish breeding tank?

You will need an Air pump and some air stones or air hoses to supply enough dissolved oxygen to the fish tank. Tilapia requires at least 6mg/l of Dissolved Oxygen. As you become more involved it is advisable to measure the dissolved oxygen levels on a regular basis. To ensure your fish health.
