For business ventures, there may also be a commercial license, operating permit, and other requirements that may be required by the state.
You must take care to make sure you properly dispose of any live fish or waste water containing eggs or juvenile file. Take the time to develop a plan for how you will raise your tilipia.

How will you maintain the proper levels of dissolved oxygen, carbon dioxide, pH, and nitrogen compounds present in water? How will you keep these warmwater fish at the proper temperature?
