FERTILIZATION IN CATFISH FINGERLINGS PRODUCTIONS

FERTILIZATION IN CATFISH FINGERLINGS PRODUCTIONS

The male reproductive organ is then prepared. This is done by mixing of the male milt content with physiological salt solution (saline water). This is done by using scissors to incise the milt sac, squeeze the reproductive content (sperm) into already prepared saline solution, mixed gently and place aside. 

The female eggs are obtained by a process called stripping. The eggs are stripped out by gently pressure the lower abdomen into a dry plastic container already prepared for the purpose. The eggs, collected are kept aside and water is not allowed to touch the content under any circumstances. The egg in milt are then mixed together, this is done by pouring the milt solution into the egg and then gently mixed together, after which a saline solution is used to rinsed the container containing the milt.

PROPER FERTILIZATION

Pure clean water is added to the mixture and then gently stir to make sure all the mixture are thoroughly mixed together.

These are then spread on a spawning net. They should be evenly spread to avoid overlapping of the egg which can cause clogging and unhatched eggs.

They are left alone for 24 hours after which the egg would have hatched out and they are seen at the corner and at the bottom of the tank.

The net is then remove and either placed in another water/tank or they are washed away to avoid pollution. 

The process of fertilization is a continuous process and all the process must be properly followed to the letter, negligence and absentism is hallmark of failure.Water quality plays a an important part in the success of the catfish farming and any other culture of other fish species
