The pond is an artificial pond created for fish breeding. For the construction of ponds it is best to use natural depressions, such as depressions and gullies. It is preferable to find such hollows near rivers, to avoid problems during the flooding of the ponds. Such ponds are called riparian. For the formation of floodplain ponds enough to block the earthworks elevated part of the shore. In front of an earthen embankment will be saved by river, atmospheric, ground water. In such ponds it is good to raise warm-water fish species.
In that case, if a future pond removed from river beds, it can be used other sources of flooding. Key ponds filled by water gushing from the ground up the keys, and brown – due to streams flowing across the land. Key ponds are created by the embankment and the strand by dividing creeks dams. These ponds are well used for the cultivation of Coldwater fish species.

Group decorative landscape modeling Sevastopol marine aquarium professionally engaged in the creation of artificial landscapes for zoo – and water parks, aquarium and Museum exhibits. Our group also has extensive experience in the application of simulations of rocks, waterfalls, caves, ancient ruins, etc. for decorating the surrounding areas, walls, swimming pools and interior decoration.
Group decorative landscape modelling was established in 1994 to perform work on the creation of a new exposition at the reconstruction of one of the halls of the Sevastopol Marine Aquarium. In the result were designed and built scenery simulating landscapes of the habitats of animals, on display in the Aquarium.
During its existence (about 15 years) our group has implemented several major projects. These include the complex “the bears continent” in the Kiev zoo, where he created a simulated rocky landscape with waterfalls and a stream, and the exhibition “Karst cave” in the building of the Water information center in the Park downtown.
