Krium marble catfish is a typical representative of a large family., who prefers to live in fresh water. In the natural environment is found in unsalted basins of the Mediterranean Sea, warm lakes and backwaters in Africa, in the Jordan River.

This species has a large oblate head with two pairs of long whiskers and a huge jaw with sharp teeth. An elongated body in the area of ​​the tail is compressed.

Scales are absent, and shiny skin is usually covered with marble patterns.

Klarium marble catfish can do without water for up to 40 hours

The color depends on the habitat and the water in which the individuals are located. The average lifespan is 8 years.

Som reaches a length of 1.7 m and 60 kg.

During the African summer, rivers and lakes dry up from the heat. To survive in an aggressive environment, nature has rewarded unusual fish with traditional gills and real lungs.

Clarium catfish crawls to a more suitable place, breathing air from 12 to 40 hours. At home, he quickly moves over land, finding the desired body of water.
Charmouth is omnivorous, therefore it feeds on amphibians, mollusks and small river dwellers. Do not give up vegetation, but more behaves like a predator. With a lack of food, it eats the weaker members of its species.

Unpretentious fish take root in any water bodies, so growing African catfish at home is not difficult. Individuals are undemanding to the quality of the fluid in which they live and are resistant to many diseases. The farm is created on the basis of installations of a closed water supply:

  1. Pool. The minimum volume of 12 cubic meters at a height of 1 m is intended for adult specimens. The pond is easy to divide the net into several parts and contain fry and adolescents.
  2. Mechanical and biological filters. To protect livestock from waste products, you need a sump. Aerobic bacteria absorb debris, which helps to maintain the pond in good condition. A storage tank is needed in which the purified liquid will be located.

African soma is not demanding on water quality and disease resistant

  1. Pump. Moisture flows through the system and into the pool.
  2. Oxygenator. Saturates water with oxygen.
  3. Automatic feeder. The dosage and frequency of food delivery without human intervention is programmed.
  4. Heating. If you plan to breed African soms at home in cold weather, then you need to take care of the heating system. Comfortable temperature is the range from +20 to +30 degrees. Special tools and an insulating coating are required.

It is possible to keep fish in the usual pond, but automation helps in growing healthy livestock. Individuals gain weight quickly, and monitoring the quality of the environment will protect against possible problems.

The view is thermophilic, so in small areas without equipment breeding is allowed only before the onset of cold weather. Summer residents experimenting with cultivation in bulk barrels and plastic tanks, but productivity is low.

A full menu affects the weight gain and immunity of individuals, so you need to know what to feed the catfish. In order to properly formulate a diet, it is important to determine the age and size of the specimens.

The raw material used:

  1. ready-mix from the store;
  2. tripe;
  3. fish

African catfish fry need to be fed up to 10 times a day to gain weight

Larvae from birth to several days feed on zooplankton. In the second week of life, they switch to compound feed in the form of pasta. For babies from 100 mg, the main element of the menu will be professional cereals.

During the day, food is given at least ten times, and the norm is 10% of the weight.

As soon as the fry reach one gram, add a grated spleen and prepared food to the diet. The amount of food is reduced to 8. After 1.5 months, the youngsters gain 20 grams, after which the frequency of feedings is reduced to 5.

At the age of two years, Charmut feeding occurs 2−3 times a day. The mixture includes fish waste, thawed carcasses and a combined feed for trout.

Every day, each individual is obliged to consume at least four percent of the food of its own weight. It is worth remembering that with hunger, they do not disdain cannibalism.

During the spawning period, females are given an enhanced diet.

To collect broodstock, you must carefully examine all catfish. They select strong, healthy females, for whom they create comfortable conditions and an individual menu.

Minimum temperature for spawning – from +18 degrees, but it is recommended to raise to +26 C. Females find quiet places with an abundance of algae and create nests.

In order to stimulate African catfish females to lay eggs, it is necessary to raise the temperature of the water and add additional medications to the diet.

Dalmatians spawn every 30 days, but for better performance, professional farmers do the stimulation. A special drug that positively influences these processes is administered once in a meal.

If the females are nervous, then the material will require anesthetic inhibition.

Milk taken from caught males. The viability of the raw material is maintained for a day at a temperature of +4 ° C. Caviar is divided into three parts in a container with water, after which they take sperm from three males and add to the eggs, gently mixing.

As soon as fertilization has occurred, the material is washed in a solution of tannin (10 g of liquid per 10 liters of substance).
