Catfish is a type of fish that can live in high densities, so catfish farming will be very profitable if done intensively.
In addition, the advantages of catfish farming is that you can get a very big profit. Cultivating catfish can also be done with land that is not large enough and can even be done using tarpaulin media.
In cultivating catfish, you must be looking for ways to make the catfish seeds grow big quickly. The main key to the catfish business is that cultivators must be good at caring for catfish seeds. However, there are still many mistakes in carrying out its maintenance.
If you can do maintenance properly and correctly, catfish farming can run with limited capital but a high success rate.
Therefore, this article will provide effective ways to care for baby fish in order to get ideal and uniform body weight.
There are several criteria that indicate catfish hatch in a healthy condition. The following is a complete explanation.
Agile and agile movements are one of the characteristics that catfish fry are healthy. Such seeds can be cultivated. You can confirm this by catching a baby catfish and watching its movements. If the seeds swim agile and agile, then these seeds are of good quality.
The health of newly hatched catfish chicks can be seen by paying attention to their condition and physical shape. You need to pay attention to the balance and completeness of the baby catfish organs. The morphology of the head and body of catfish seeds must be balanced and their limbs must also be complete.
In addition to physical condition and shape, uniform size of catfish is also a characteristic of healthy catfish fry. Uniform seed size indicates that newly hatched catfish are in good health. With a uniform seed size, you can avoid losses due to cannibalism.
Those are the characteristics of newly hatched catfish in good health. When the baby catfish reaches 4-6 cm in size, the growth of the baby catfish will be fast and uniform. However, you need to pay attention to sufficient feed supplies so that the baby catfish grow healthily and evenly.
Catfish eggs will hatch around 30-36 hours after fertilization at 23-24℃. Post-hatching larvae maintenance is carried out in hatching containers that are flowing with water and equipped with aeration that is not too tight so that the larvae do not stir up.
The maintenance of the larvae in the container is carried out for 4-5 days without feeding, because the larvae at that time still use the egg yolk in their body as a food source.
By the 5th day and so on, the yolk in the larvae has run out. Further maintenance is carried out after entering the age of 5-21 days by providing feed in the form of finely chopped silk worms first because the size of the fish's mouth opening is still small. Giving silk worms until the larvae are 12 days old.
Here's how to raise baby catfish that are good and right:
As previously mentioned, you must ensure that the pH of catfish pond water is appropriate and odorless. Pool water must always be clean so that the baby catfish are not easily stressed and die.
You need to choose a parent catfish that is old enough and healthy. You need to know the appropriate criteria for catfish broodstock. The male parent can be spawned when it is more than 10 months old and the female parent is more than 1 year old.
Try to keep the oxygen level in the pool sufficient. What you have to do is provide a stream of water in the hatchery pond so that oxygen levels are met. Provide a constant flow of clean water in the catfish pond with strong water pressure.
After you know how to care for catfish babies, do you know what causes catfish babies to die after hatching? The following are the reasons why baby catfish die after hatching:
Poor pond water quality conditions are not suitable for the growth of catfish fry. Although adult catfish can live in poor water conditions, the young catfish cannot survive if the pond water quality is poor.
You have to maintain the quality of the water, the pH of the pond needed by catfish is 7-8. Pond water that smells and contains ammonia can cause baby catfish to die after hatching.
The male and female parents who were spawned were still very young. If you spawn broodstock that are not old enough, it will produce catfish that are of poor quality and allow for death after the eggs hatch.
The oxygen content in the catfish pond is low. This can interfere with the breathing of catfish children, causing death after hatching.
The main thing that needs to be considered in cultivation is to take good care of the baby catfish. Why is that? The reason is, caring for catfish children will improve fish health and accelerate growth.

The time needed for catfish to grow up is 3-4 months. Catfish are said to have a fast harvest cycle, usually 8-11 catfish that are ready to be harvested per kilo.
How to raise catfish so that they grow up quickly is to maintain the quality of pond water, provide feed according to the age of the catfish, choose catfish broodstock that are old enough and healthy, and have sufficient oxygen levels in the pond water.
