4. Standing Waters
The ichthyofauna of the mountain lakes includes 15 species, all of them belonging to Salmonidae and Cyprinidae. The ichthyofauna of the large and small reservoirs and fish farms has developed as a result of intensive importation of economically valuable stocking material as well as the adaptation of genetic stock from the local aboriginal fauna. Cyprinidae species predominate.
As a result of this general survey of the Bulgarian freshwater and brackish water ichthyofauna, we have revised upwards our figures on species composition.
This is due in part to the research methods employed, but also to the intensive importation of new species and natural expansion in the ranges of other species. Simultaneously, however, populations of the dominant species have undergone changes, resulting in a definite decline in fishstocks. We require a comprehensive program to preserve the genofund and to increase the fishstock.

5. Overview of the Bulgarian Freshwater Ichthyofauna
The contemporary Bulgarian ichthyofauna consists of 207 species and subspecies, 122 of which inhabit fresh and brackish waters - rivers, wetlands and natural and man-made lakes. The formation of the freshwater ichthyocomplex of Bulgaria's northern rivers and watersheds up to the Stara Planina Mountains has been influenced by its direct connection to the Danube River, which possesses the richest ichthyofauna in Europe. The other rivers and lakes of the Black Sea watershed area are inhabited by freshwater species (including Ponto-Caspian and Boreal-Atlantic relicts) and Mediterranean immigrants. Some Danubian species also occur, the number diminishing from north to south. The rivers and other water bodies of southern Bulgaria that belong to the Aegean watershed contain species that are specific to that region as well as some Danubian and Black Sea species.

6. The Danube River Watershed
The Bulgarian section of the Danube River and its bulgarian tributaries are inhabited by a single and unified ichthyocomplex that includes 74 species and subspecies. Thirteen species are found only in the Danube itself. Ten others are found only in the tributaries: Salmo trutta fario, S. gairdneri irideus, Phoxinus phoxinus, Barbus meridionalis petenyi, Cobitis aurata bulgarica, C. aurata balcanica, C. elongata, and Cottus gobio, as well as Coregonus lavaretus and C. peled, which are being introduced to the waters near the Iskar Dam. These are exclusively cold-water species, and are adapted to the conditions of the mountain areas. Some are found in the rivers of the plain as well, but never reach the Danube River.

7. Esox lucius
A representative of the family Esocidae - Shtukovi. Reached major proportions - a record fish are over 1.5 meters and weighing kg. They are usually smaller.Growing extremely fast - in proper nutrition for one year may reach sm  Habitat: inhabitant of standing water - lakes, ponds and lakes or rivers in areas with low flow - meanders, reef, pools. Fitofilen kind - always kept near aquatic vegetation, among other lies, and lies in wait victims. 

8. Chub - Squalius cephalus
A representative of the family Cyprinidae - carp. Length reaches cm, rarely more; weight kg? Habitat: meeting in almost all parts of rivers, plastic kind; meeting and standing ponds - martvitsi, lakes, ponds, reservoirs, preferences substrate is chakalsetoto river mullet or sand bottom

9. In reservoirs of Stara Zagora keeps many animals, birds and fish
In reservoirs of Stara Zagora keeps many animals, birds and fish. Around them there are factories and enterprises that have upgraded to protect their health and their lives. This will be maintained their population and reproduction

10. Esox lucius have few natural enemies, but because they are prone to cannibalism and trophy for favorite sport fishermen, their populations are relatively stable

11. PELOPHYLAX RIDIBUNDUS
The waters of rivers shelter plant and animal species that have adapted to this specific environment and are not found elsewhere.

12. Goose lives in ponds and rivers but, like many other animals took the hard route of migration. When people understand what, how and why it occurs in animals then creates an opportunity to acquire entirely new knowledge about them, their cultivation and conservation in the environment we inhabit.
