It all started with the fact that I had a broken fire acrylic bathtub, corner shape, the depth of nearly 60 inches and a capacity of 300 liters. After not artful manipulations for the installation of a pond at sunken place in advance, I patched with silicone unnecessary holes and cracks plastic tanks. Don’t get bogged down in the appearance of the pond, will focus on the construction of the reservoir. More than two dozen algae were launched with a variety of ponds and rivers. Snails – pond, of the coil. Frogs and common scoter, as it turned out later hatched out from eggs on the plants. Emergent plants – rushes, sedge, coin, with roots planted in pots with sand. The water in the pond had to be refilled on average in 2-4 days no more than 10 liters, and the normal from the tap, a little chlorinated. In June the water temperature even at night does not drop below 15-18 degrees Celsius. Continue reading
One should distinguish between foods used for fish production in ponds and in the so-called industrial environments (fish tanks, pools) where fish are kept at the super-dense plantings (up to 250 ind./m). In ponds, even at high planting densities (over 5 thousand ind./ha, or 0.5 individuals/ m2), the fish has the ability to consume natural food that is a source of biologically active substances — vitamins, minerals, and valuable protein. Therefore, pond feeds does not impose such stringent requirements on the balance and value of diets.
Quality set of feeds with a high enough level of protein, vitamins and other components can be improved by the fish due to consumption of biologically valuable natural food. At stocking density of fingerling carp in ponds 5 thousand ind./ha the proportion of natural food in the content of their intestines is not less than 10 — 15%, with a density of 30 — 35 thousand ind./ha, it is further reduced, but is still 5 — 7% of the daily diet on average during the season.

Soma is not for nothing called a true aquatic predator of gigantic proportions – it can grow up to 5 meters in length and weigh more than 250 pounds. And to catch such a trophy is the dream of every angler. However, in most reservoirs it is possible to meet ordinary and catfish weighing up to 10 kilograms, to catch which is no less prestigious.
Since it prefers to conduct a night way of life, and fish for the purpose of catching better this time. Som lives in freshwater lakes and rivers of the European part of Russia, in the Caucasus it occurs in rivers and in lakes. In most cases, leads a benthic lifestyle, perfectly camouflaged at the bottom of the pond to catch their prey. The diet of catfish are other fish, shellfish, but in some cases, soms can be seduced to Pets and waterfowl. Continue reading
