In ancient times, 65 million years ago (the end of the age of dinosaurs), on the border between the Cretaceous and Paleogene periods, lapped the ancient Tethys ocean . which, in geologically near future had to disappear and leave behind the Mediterranean . The black and Caspian seas and the Persian Gulf. The first two are further connected by the Atlantic ocean, the latest from the Indian.

The formation of the Strait of Gibraltar and the Mediterranean sea (5 million years BP)
The Strait of Gibraltar that separates Morocco from Spain, is only 15 km width. Perhaps the flooding of the plains by the ocean between Africa and Europe and is reflected in the ancient Greek myth of Debelyanovo the flood that supposedly happened in “ancient Greece”*, namely in the district of Dodon and of the river of Aheloy [I think it was near the Caucasus, and then we can talk about the Black sea]. There is another myth, that the rocks of Gibraltar and Ceuta opened Hercules.
The breakthrough of the Ocean through the Gibraltar – perhaps the work of man.

In recent years, the breeding of decorative fish species, such as koi fish, is a favorite pastime of lovers of the exotic. Besides, it’s still a pretty profitable business. Those Japanese with fancy coloration fishes are of great interest not only to aesthetes. Garden ponds with such inhabitants become the perfect decoration for any suburban area. The owners of artificial lakes should take into account the fact that koi carp is quite cold and prefers clean, flowing water with high oxygen content. This environment will provide the exotic fish comfortable habitat conditions.
For successful breeding and keeping koi it is important to know that water is the most important factor in this wonderful lesson. First, the reservoir must be equipped with reliable high-performance filtration system, which will provide a continuous flow of clean running water.
Secondly, it is extremely important to ensure you receive enough oxygen, which is pumped by a compressor or by passing water through artificially arranged waterfall or cascade waterfalls. Thirdly, regular cleansing of the bottom of the reservoir to keep the water clean and clear, quite suitable for fish health.
The optimum water temperature for koi is 8-28°C. With its decrease koi spuskaetsya the bottom of the reservoir. And if the water temperature continues to fall, this can lead to fish kills. That’s why in autumn it is necessary to take care of the wintering of their Pets. A special attention should be paid to the nutrition of carp. For the safe transfer of cold weather, the fish should be given food, having in its composition a high percentage of protein and fat. Continue reading
1. What type of water body (pond) is better? Are a lot of options, from wooden or plastic reservoirs with plastic lining and finishing of concrete reservoirs with a tiled surface. Some owners of water bodies use dirt, they put it on the bottom of a wooden or concrete ponds to make the pond more organic. In terms of the reservoirs also differ greatly from each other, the volume ranges from 10 liters to several thousand.
The reservoirs (ponds) with fish
Let’s assume you have a plastic reservoir with capacity 200 to 250 litres or say, wooden with a plastic strip.
2. How to run the pond? Probably the pond was sold with the manual. Please read it carefully and follow all instructions. Perhaps you will read that you must add water conditioner to get rid of the chemicals that are added to tap water. Be patient. Fill the reservoir with running water, add the conditioner and wait at least three days prior to plant fish there.
At the same time you need floating food for goldfish, for example “TetraFin” fish food for small fish and “Tetra Pond Floating Food Sticks” for large. Owning a net (20 cm diameter) with a handle long enough that dottydo any point of the reservoir.
3. Choosing the right place. You can put the reservoir wherever you want, however, you should avoid places where a lot of leaf litter and organic fragments. As an alternative – you can close your pond from falling leaves through the screen. Continue reading
