Long gone are the days when the hundred-kilogram catfish was considered a normal catch.
In the late twentieth century desyatikilogrammovy “somenos” (A. Sabaneev) – a significant event in the life of a fisherman. Therefore still affects the success of the Italian Armando Frisaro, which was caught in a small lake in the North of Italy catfish weighing 150 kg.
The area to the North of Italy – pool rivers and Adige, dotted with small, but clean and deep lakes, which are famous for their catfish. Instances up to 50 kg are not uncommon, and previous personal record Armando catfish weighing 85 kg. In addition, in the early 90’s in the network of local fishermen, Industrialists got 200 -killogramovy kgs! So the Italian success was not accidental. Anyway, in preparation for fishing, fisherman hoped for a “serious” fish: a special rod for fishing, 300 meters strong fishing cord with a diameter of 0.6 mm, a 100-gram sinker. And tempted com monster dead fish on the rope. “Fish” was the sardine with a length of 30 cm. Armando says that large catfish only take on the big bait, before he used a carp with a length of 40 cm, or 25 cm roach Continue reading
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.
