Malek fish: stages of development

Fish fries are the main planting material for pond farming. With the help of it, all water bodies, both natural and artificial, are grounded.

Spawning

Spawning is a responsible time for fish. At this place is always noisy, you can hear frequent splashes of water. The beginning of spawning is mainly due to sunset. Continues all night, grabbing the morning. In total, spawning can last 10-12 hours.

Among pond fish, the female carp is very prolific. The weight of caviar is half the weight of the female itself. Caviar is light green in color. The quantity can range from 342,000 to 621,000 pieces. Few people live until their sex. Lakes and river fish, like marine ones, have a lot of enemies who do not mind eating caviar. Malek fish are the desired prey of any predator.

Breeding fish

Frying with fry pursues four goals:

• a commercial;
• Sports;
• Natural;
• Decorative.

Breeding fish in a pond, and after catching it and selling it is a very lucrative and uncomplicated business. A real fisherman knows how to monitor fry, how to grow, what to feed and so on. As a result, a large fish grows , which is sold tens of times more than the price of fry. Both river and sea fish are suitable for these purposes. Malka carp, for example, are bred by owners of artificial reservoirs, pursuing a sporting goal. After all, what kind of fisherman does not want to catch a big catch? Sport fishing or hunting is an occupation for real men and true anglers. Such a holiday will suit everyone.

Fish farmers pursue a natural goal. It consists in eating excess algae, destroying predators of other species of fish, improving the reservoir. And, of course, the owners of large private houses, who can afford a small pond, or those who decided to put an aquarium in an apartment, pursue the decorative goal.

Do not forget that although this larva, the young fish is insatiable and agile. Therefore, growing immediately fry of fish predators and harmless herbivores, you can lose one of the species. The size of the eggs varies from 1.25 to 1.5 mm. The younger the female, the smaller is the caviar, it is large in the old individuals. This positively affects the development and endurance of the future fish, which will be large and resistant to adverse habitat conditions.

Fry

At the stage of hatching, the young fish has a size of 3 to 6 mm. The first 2 days, small fish of many species sit on the ground, attached to the aquatic vegetation glutinous glands, tail down. The food is due to the yolk bubble. And only on the third day the young fish goes to mixed food. At this time he feeds on zooplankton and zoobenthos. As soon as the water warms up well, the fry completely pass to the forage. They accumulate nutrients for the coming cold. The fry must have a long and cold winter, and without the supply of nutrients they will not survive.

Segallet

A juvenile is called a young fish, up to a year old. By the end of this period, it weighs only 20-30 grams. The fry base, the concentration of oxygen and the temperature of water influence the fry growth significantly. On scanty fodder, juvenile poorly increases in height and weight. The same is true for the temperature regime. As at low, and at high temperature fry stop eating.

How does the fish behave in winter? Carp fry, for example, cold forces you to descend into the bottom holes and stop eating. This happens at a temperature of +7 to -8 degrees. Later, when the temperature drops even lower, the juveniles fall into anabiosis.

In this state, any movements are minimized. Fry do not feed and practically do not breathe. If in the summer at a high water temperature the fish makes about 60 sighs per minute, then in the winter period - only 4-5 sighs. After wintering the young fish is called an annual, and by the end of the year - a two-year plan. Having survived another winter season, he becomes a three-year-old.
