The first thing that you need to pay attention, this is the cover of the pond. You can use concrete, flexible waterproof coating, the finished semi-rigid structures, the latter made of fiberglass or polyvinyl chloride, are famous for their strength, available in different sizes and shapes. Just wanted to draw Your attention to stations for mechanical water purification. all the details about which You can read by clicking on the link.
Flexible waterproof covering made of polyethylene of varying thickness. Some of them have the UV protection that prolongs material lifespan. The advantage of this coating is that you can create a pond of any shape and size. Continue reading
For breeding more demanding of the oxygen content of the water species (pike perch, carp, etc.) will require a larger reservoir size. If the plot runs a small stream, it can be used in a complex with swimming pool, ensuring the construction of the reservoir production, and breed of farmed fish can vary considerably.
When breeding carp, carp farming ponds can be make smaller. The shape of the pond may be different, but more exotic and will look a pond with irregular shapes: round, oval, or curvilinear. Rectangular pool is the most suitable to the rectangular lines. The depth of the pond it is better to do one level because of uneven-age fish require different temperature water regime. Therefore, the differences in depth can be from 1.5-2 m in the center of the reservoir up to half a meter and less closer to the shore and along the edges. Better the bottom to hold sloped, beach — concrete steps with a width of 30-40 cm and 20-30 cm depth of Such stair drops will need for growing plants in shallow containers, and for easy access to the water. Therefore, they should not hold the entire perimeter, but only in the place where the most convenient approach to the water mirror. If in the winter the fish are fully fished, in the water equip wintering well. Continue reading
In the World ocean inhabits 180 thousand kinds of animals
According to scientists, man eating fish and other marine animals that uses only 0.02% of the primary production of seas and oceans.
Blood pressure in arthropods 5-10 mm Hg. article on the green frog – about 40, active fish – 65-75, birds and mammals – 120-180.
In rivers of Central Europe is inhabited on average 40-50 species of fish in the Danube – about 70 species, while the Amazon is more than 1 thousand kinds of all kinds of fish.
Many animals are very demanding in terms of ambient temperature. For example, Antarctic fish Trematomus lives at water temperatures of 1.9 O. temperature Fluctuations in their habitat at all times of the year do not exceed 0.1 A. Already at +60 the fish dies. Continue reading
