How to stock tilapia
Before the arrival or even the purchasing of the fish, you should determine the quantity and size of the fish you wish to stock because overstocking can pose serious threat to fish’s health.
Fish should be slowly adjusted to water temperature and chemistry. Proper acclimation requires minimum 15 – 20 minutes of gradual adjustment for every 10-degrees difference in water temperature.
After temperatures have been equalized, gently allow fish to swim out in open water by submerging the container.
How to feed tilapia
Feeding of tilapia is done based on percentage body weight. The main problem that most farmers encounter is overfeeding. Overfeeding generally causes deterioration of water quality which then kills the fish.
How to manage water quality
Good water quality is necessary for the success of every farm. Some parameters to keep in mind are as follows:
- Dissolved Oxygen: This is the amount of oxygen in pond water that is available to be used by fish. The acceptable range for freshwater fish is 5 – 7mg/L
- Ammonia: Comes from the decomposition of wastes. It is very poisonous to fish and will cause death. Levels should be below 0.05mg/L.
- Nitrite: Very poisonous to fish and causes Brown blood disease, which kills fish. Must be below 0.01mg/L
- Hydrogen Sulphide: Colourless toxic gas with an odour similar to rotten eggs. It kills fish by interfering with respiration. However, it can be treated with potassium permanganate or liming.
