Naturally Spawning Catfish

Naturally Spawning Catfish

The first step for naturally spawning catfish is to choose a female and male ripe gonads. Choose a pair of catfish that has a balanced weight, the goal that one parent is not the fear of the other parent. Balance the weight of influence on spawning success.

Before the process of spawning catfish done, prepare beforehand pond spawning. Pool is ideal for spawning length of 2-3 meters, width of 1-2 meters and a depth of 1 meter. Should bottom of the pool is made of cement or fiberglass for easy oversee fertilized egg. Previous pool must be drained and dried, then filled with water depth of 30-40 cm. Use good quality water, clean and clear.

Kakaban pairs, can be made with bamboo fibers are clamped with the size of the pool area. Use a weight that is sinking kakaban not float on the water surface. Kakaban function for egg hatching results are not scattered and easily moved. Make kakaban as solid as possible so as not to clutter by active breeders. Water for spawning catfish should be rich in oxygen, therefore provide aeration in the spawning pond. Or, if sufficient water is available to back flow in and out. Adjust the water flow 2-3 liters per second.

The right time to enter into the broodstock spawning pool is in the afternoon. Usually catfish will spawn around 23:00 until 05:00. During spawning catfish ponds should be closed, to prevent the parent fish jump out of the pool. In the mornings, usually the spawning process is completed. The eggs will stick to kakaban. The eggs were successfully fertilized failed colorless transparent while white milk.

After spawning is completed, immediately lift the parent of spawning catfish ponds. This is to avoid eggs eaten by the parent fish, because after the parent spawning female fish will feel hungry. Furthermore, the fertilized egg hatched. Hatching can be done in spawning pool or elsewhere, such as aquariums, fiberglass or pool tarp. During the hatching process the supply of oxygen (aeration) should be maintained and stabilized temperature in the range of 28-29 C.

The fertilized egg will hatch into larvae within 24 hours. After it failed to immediately separate the eggs or larvae that die to prevent the growth of fungus. The larvae that hatch will survive without supplementary feeding for 3-4 days. Next do the larval rearing
