Pond fish farming. Species of fish
In home waters well bred carp, crucian carp, tench, white Amur, silver carp, pike, Zander. With low-value, weed fishes in waters are able to dwell in bleak, perch, gudgeon, roach and loaches. Requirements for the environmental conditions the fish are divided into 2 types: thermophilic and Holodnaya.
Thermophilic (carp) nice grow, develop and prefer stagnant water, which heated well, with a moderately developed in them by aquatic vegetation. They breed in the summer-autumn period of time. Limitat eggs on vegetation. Often by a number of days from the eggs emerge the larvae, which after become fry.
Cold-water fish demanding clean water with a high concentration of oxygen in it. Eggs lay fish, usually late in the fall on stony ground, where it develops for some months. In backyard pond, it is advisable to breed a number of fish species, increases the total output of fish products due to the different spectrum of power. Continue reading
A hybrid plant, various garden forms which are widely distributed throughout the world.
Grown water Lily “Sea rose” in small artificial ponds . Very beautiful flowers, of various colors. Cultivation in the aquarium is possible, but this water Lily leaves less beautiful, than other nymphs. In the aquarium you should use a fairly large container with a large surface area of water. The water level should be relatively low (not more than 45-50 cm). In winter after flowering water Lily growth slows.
To contain the “marine rose” you can have a warm and moderately warm aquarium . The suitable plant temperature is from 20 to 30 °C, optimum 22-25 °C. in Summer, during the growing season, the temperature can be raised to 26-28 °C, in winter it is better to reduce to 20 °C. water Hardness should be small, less than 6°. In alkaline water, the plant develops a little bit worse than in acidic or neutral. For acidification of water can be added to the aquarium peat extract.
