Biofloc fish farming is a system that involves the use of microorganisms to convert uneaten feed and fish waste into microbial protein, which is used as a food source for the fish. The water parameters for biofloc fish farming can vary depending on the species of fish being raised, but here are some general guidelines:

Temperature: Most biofloc fish species thrive in water temperatures between 25°C and 30°C. However, some species such as tilapia can tolerate water temperatures up to 35°C.

pH: The optimal pH range for most biofloc fish species is between 7.0 and 8.5. However, the pH level can vary depending on the alkalinity and hardness of the water.

Salinity: The salinity level for biofloc fish farming can vary depending on the species of fish being raised. Some species such as tilapia and catfish are freshwater fish, while others such as seabass and pompano are marine fish. Generally, a salinity level between 1-5 ppt (parts per thousand) is suitable for most biofloc fish species.

Dissolved Oxygen (DO): A DO level of at least 4-5 mg/L is recommended for biofloc fish farming. Higher levels of DO are preferred, especially during the early stages of fish growth.

Total Ammonia Nitrogen (TAN): TAN levels in the range of 1-2 mg/L are recommended for biofloc fish farming. High levels of TAN can be toxic to fish, and can lead to poor growth and increased mortality.

Nitrite (NO2): Nitrite levels should be kept below 0.5 mg/L to avoid toxicity to fish. High levels of nitrite can lead to reduced growth and increased mortality.

Total Suspended Solids (TSS): The TSS level in biofloc fish farming should be maintained between 20-30 mg/L. High levels of TSS can lead to reduced water quality and increased stress on the fish.

It's important to note that these parameters can vary depending on the specific requirements of the fish species being raised, as well as other factors such as feeding rates and stocking density. Regular monitoring of water parameters is necessary to ensure optimal fish health and growth.
