First we have to decide about the place for cultivating Karimeen (Pearl spots). Ponds or fields can be selected for this. The place selected for farming Karimeen (Pearl spots) should be cleaned first. Drain off the water and mud and all sediments from the pond. If fields are selected, the four boundaries should be protected by erecting bunds with good height. The pond used for farming pearl spot should have an area of 1 or 2 cents. If we are farming in a larger scale, add agricultural lime in the ratio of 3-4 kg per cent followed by cow dung at the rate of 5 kg per cent into the pond. Leave the tank as such for 2 weeks before dropping the pearl spot fries. Instead of dropping the fries, it would be ideal to drop pairs of adult fish ready for breeding. Since the Karimeen (Pearl spots) lay a large number of eggs, this method is ideal. Also the price of the fries are high, this is cost effective also.
The pearl spot usually lays eggs on the wooden branches and slanting roots seen at the bottom of the water .The Karimeen (Pearl spots) needs a surface with an inclination of 40 – 45 degree in order to lay eggs. So such a inclined area has to be created at the bottom of the pond, and we have to put small dry twigs or wooden logs or bricks and create a breeding atmosphere. The most ideal for pearl spot breeding is putting dry twigs. Since there is the presence of algae on the twigs, it will become a food for the pearl spot and the fries. Care should be given to feed the fries properly during the growth stages. Waste from meat, powdered oil cakes, artificial feed etc. can be given to the fries. The amount of food given should be optimum as excess feed may contaminate the water. We should not shift the pearl spot fries from brackish water to fresh water suddenly. We have to mix the water little by little and then shift the fries. Always use encircling nets or traps to collect the fries. Otherwise it may damage the fries of pearl spot. A fully grown Karimeen (Pearl spots) can be sold in the market depending on its weight and similarly the fries can also be sold for a good fortune .
