Carp (fish), carpia, Korop, carp (Cypriuns carpio), fish herewith. Cyprinidae (see), characterized by little oblate body covered with large scales, a blunt rounded snout, and 4 thick tendrils and serrated on the rear edge of the third ray of the dorsal and anal fins. Found in rivers throughout Europe, Asia, and divorced in the North. America, also in the Azov, Black and CASP. seas at the mouth of the rivers; reached. length from 30 cm-1 m, rarely up to 1.5 m with a weight of 15-20, and up to 35 pounds. There are several varieties (Royal Hungarian K.). In Europe everywhere is bred in ponds where live 100 to 200 years, and feeds on vegetable and animal food.
Cyprinids (Cyprinidae), a family of bony otkratougolnah (Physostomi) fish. Numerous (up to 2 thousand species) members of this predominantly freshwater family are characterized by the absence of oral teeth, which is to soften food, there are several rows of teeth on ninepatch bones. Common everywhere except Rep. America, Australia and polar regions. Males during the breeding season are the so-called. marriage dress, reflected red or pink coloration. Many are commercial fish; to K. are: carp, carp, gudgeon, roach (roach, roach), tench, nase, bitterling, Sopa, vimba, bleak, Shemaiah, sabrefish. (Encyclopedic dictionary of Brockhaus and Efron).
Carp is the flagship of the family Cyprinidae. But first, we are not talking about him, and about his ancestor — the common carp. This river carp, or carp,is very beautiful. It is covered with unusually large dark Golden-yellow scales, which on the back of it, with a bluish tinge, and the belly lighter; it seems as if the Golden field he is all strewn carnations with copper hats.

For anybody not a secret that summer vacation brings a lot of various positive emotions that may be encountered by everyone who comes to the beach. However, despite the fact that relaxing on the beach is an opportunity to polarinstitutt in the warm waves and bask under the solar rays, there are many other points that can in addition to various amenities and to bring a number of significant troubles.
Therefore, even during rest, should pay attention to the potential dangers and learn about how to cope with them in critical situations, including when trouble brought various sea inhabitants.
The first thing to do before the trip along with the usual charges, to prepare a first aid kit, which will have all the necessary medications in order to cope with various alterations that await us on the rest. This applies to various means to improve digestion, and antiseptics and other medicines, the receipt of which cannot be stopped or required to receive in case of serious health problems. In addition, you should look for information about what animals are a threat in the region, where You go on vacation, and in accordance with data found to acquire the necessary means.
As for the provision of first paasikiventie on vacation after contact with someone from inhabitants of the coastal zone, it all depends on who has had to face. However, as practice shows, most often along the coastline, you’ll encounter sea urchins, jellyfish and stingrays. Despite the fact that the sight of those representatives of the animal world do not pose a serious risk, but the consequences after meeting with the individual instances can be extremely serious.

The Mediterranean sea stretches from West to East from 5.5° W D. to 36° e and is located between the Parallels of 30 and 45° N. lat. Its southern coast belongs to the African continent, and the Western, Northern and Eastern Eurasia. This is the most secluded pool of the World ocean (Fig. 2.15). It belongs to the Atlantic ocean, but connected with it only by the narrow Strait of Gibraltar with depths of from 280 to 320 m In the North-East through Dardanely, the Marmara sea and the Bosphorus. where the depth reaches only 50-60 and 30-40 m respectively, it communicates with the Black sea. It is believed that the limited water exchange with other basins of the World ocean is one of the main reasons for the formation of the special hydrological regime. This understanding is based on the decisive role of the thermohaline circulations in the dynamics of the sea.
The Mediterranean sea is composed of many separate parts. Tyrrhenian sea, the Algerian-Provencal basin, the Alborán sea, Balearic (Iberian) sea, Gulf of lion, Ligurian sea, the Central basin (between the Sicilian Straits and the Cretan-African channel), Adriatic sea, Levantine Sea, Aegean sea (has a lot of Islands, and complex bottom topography). The Aegean sea are divided into 3 pools. Athos in the North, Chios in the middle part and most glubokinsky pool. Continue reading
Porzului, anybody that has a pond in the country, wants to revive it: to plant water plants, make a stream or waterfall. And many of the owners of these ponds are installing a fountain, and finally, trigger fish. Stocking of reservoirs is a common phenomenon in our days. And the school of fish not often associated with utilitarian needs, not to feed the family, but for beauty. For aesthetic pleasure. Fish and plants in the pond closely interact.
In the daytime the plants, using the reaction of photosynthesis, water consume carbon dioxide and give back oxygen. Fish breathe this oxygen. In the dark aquatic plants, like fish, consume the oxygen and works the same as the fish exhale carbon dioxide. When plants in the pond the excess, then in the morning, when the concentration of oxygen in water is negligible fish starts to die from lack of oxygen.
M OST fish species, e.g. carp or other herbivorous carp. They eat aquatic vegetation. With one hand they are cleaning the pond of excess vegetation, but on the other hand they can destroy the aquatic plants that you are trying to cultivate. Spending and the stocking of the pond, it is necessary to consider, if you want to have both fish and aquatic plants at the same time. Ie need to consciously choose the right types of plants and fish species for your pond. Continue reading
Greenhouse gas emissions in the coming decades could have a significant impact on oceanic life forms, with such dire predictions were made by the expert on marine biology Michael Beeman from the University of California in Merced. – Concern about this issue in informed circles is growing because human activity is very rapidly changes the pH (acidity) in the oceans. And although we don’t know what will be the final effect of changing the nitrogen cycle, the experiments are being conducted worldwide, and based on them we can assume that the effect will be global.
According to him, the growth of carbon dioxide emissions, increased by the burning of fossil fuels and other human activity increases the acidity of water, which, in turn, significantly alters the nitrogen cycle in the sea. And because nitrogen is an essential nutrient for living organisms, although, as it turned out recently, some life forms can adapt to other elements, eventually the process will affect all forms of marine life, reports innovanews .
During his research Dr. Beman lowered the pH of water at six different sites in the Atlantic and Pacific oceans. In each case, when pH was lowered, and decreased generation of oxidized forms of nitrogen, which usually uses phytoplankton and drugability. This nitrogen is produced through the oxidation of ammonia in sea water by microorganisms. According to the scientist, these results can be used to assess the potential impact of oxidation on the nitrogen cycle in the sea and marine life forms in General. But the observed effects require additional research. Continue reading
