Total Vegetation

To a depth of 2-3 m dive for food only diving – red-crested Pochard, Tufted Duck. Therefore, for dabbling ducks floating vegetation or need shallow water, and for diving – deep water. Aquatic vegetation is completely provides nutritious food waterfowl. It contains a large number easily digestible protein, minerals, carbohydrates, fat, carotene, vitamins, minerals and secretin on the aft superior to clover and alfalfa. But the various aquatic plants are broken at different times of the year. To feed the pond had all the time, it must be a corresponding set of plants. If consumed in the spring of overwintered zelznye grow back or younger parts of plants, from late July to the diet of waterfowl, gradually dominating over foods of animal origin, are beginning to enter nodules comb pondweed, arrowhead onions, frog kidney and Susak, and as the maturing – and the seeds of pondweed, cattails, sedges, rezuhi, chastuhi, grechishnika etc.

Aquatic vegetation plays in the lives of waterfowl and other very important role. The seeds of some pondweed, especially ezhegolovnika contribute to grind food in the stomach. It is easily cultivated aquatic vegetation by sowing seeds, planting tubers, rhizomes, bulbs or purely vegetative means. Duckweed. This is a favorite feed wild ducks, geese, water hens.

To areas covered with duckweed, is always going to waterfowl. Feed ryasok properties are very high. According to the chemical composition of duckweed is close to the grain of cultural crops, and on Total crude protein does not yield seeds of legumes. Duckweed are easily propagated vegetatively. Their are several types: a small duckweed, trilobal, mnogokorennaya and roach. Pondweed. Perennial aquatic, marsh grass and rarely creeping rhizome and a simple or branched stems, which inhabit the lower number of small animals, insects and their larvae. Pondweed – an excellent food for waterfowl. Thickets pondweed completely cover shoals, bays, backwater,, rolling rivers, forming arrays of underwater vegetation. The average yield of green mass with a depth of 100-150 cm up to 400-500 p per 1 hectare. Pondweed rooted at the bottom of the pot they are immersed, visible above the surface only flowers. Pondweed rhizomes multiply tuberous thickenings or seeds. The best soil for them – a 15-cm layer of silt on the sandy bottom. Ducks most readily eat the following types of pondweed: floating, comb, kinky, amplexicaul, shiny, pronzennolisty and small. The latter creates the underwater meadows to dense thickets. In July, ponds are overgrown with them entirely. Elodeya (water plague, pestilence water). This is a perennial plant with a scuba very leafy, 2-3 m long, stems. Displacing other species, creating dense thickets to a depth of 3 meters and is able to tighten the continuous body of water with a green carpet. At one point many years are left. Submerged surfaced vegetation itself significance as food does not have, but it is a supplier of feed in a variety of molluscs, crustaceans and insect larvae. Some of these same species of plant in the spring before the appearance of soft water vegetation, as well as the fall become a significant source of supply.
