Its main purpose was to draw international attention to what irreparable damage to the sea causes overfishing, water pollution and global warming .

On this day in the participating countries this document a variety of activities devoted to the problems of the Black sea and preserving its unique ecosystem. Their main aim is the formation of public opinion in defense of the sea and facilitation of education of ecological culture of the population.

TROPICAL FISH AS A MIRROR OF GLOBAL WARMING

In the far Eastern marine reserve, founded by the Institute of marine biology Feb RAS in 1978 in Peter the Great Bay, met on several occasions fish-aliens from the tropics, but especially frequent were such meetings in recent years.

In August 2001, in the Bay West of the island of furugelma members of the research group during diving excursions met on a sandy shoal flock of small, very mobile fish. After a few days of feeding fish are used to treat and allowed himself to be photographed. It was North of the dog-fish (fugu) Blowfish from the family. They live in the coastal zone; reach a length of 50 cm Due to the special musculature of the pectoral fins of a puffer fish can move not only forward but also backward. Jaw teeth Fugue fused with each other and form in each jaw a pair of inserts separated from the front, it allows them to eat well attached to the substrate organisms-obratitesj. In case of danger fish filled with water or air saccular outgrowths of the stomach and swell, taking a spherical shape. Puffer fish are often toxic in their bodies contain dangerous poison – tetrodoxin. However, purified from the skin and peritoneum and properly cooked meat of these fish is used for food in many countries of South-East Asia, where the dish “fugu” is a delicacy.

Letom here have been found in shallow water Chinese yellowtail, amberjack or big. Seriola are large predators, reaching lengths of over 1 m; live on the continental shelf and form a small but dense aggregations in the water column.

In the Ukrainian rivers appeared dangerous predators

Every year commercial fish species is becoming less. Scientists warn that may soon Ukrainians can not take grandkids fishing — will catch nothing.

“Back in the thirties dried up stoked the stove”

— In recent years we have almost completely destroyed river ecosystem, — says Sergey Mezhzherin, doctor of biological Sciences, Professor Institute of Zoology. I. Schmalhausen. — In Ukraine there is a huge estuary — the sea of Azov, which was considered the most cost-effective and highly productive ecosystem. Here the fish bred naturally. About how much it was in Azov sea, says a historical example: in the area due to the lack of firewood up to the thirties of last century the house was heated by dried specimens, casting them into the furnace instead of logs. Now it seems incredible, however, the number of freshwater fish in the country (even compared to the seventies of the past century) has decreased at least thirty times. Peregorazhivanie dams of the Dnieper, Kuban, don, led to a sharp saloneni water. Now we can confidently talk about a real environmental disaster and in fact of mass death of fish in the rivers of our country.

“Every year in Ukraine disappear two rivers”

Another reason for the lack of fish in Ukraine: loss of grasslands and floodplains — the most scarce of the environment and natural resources in our territory. In addition, in recent years disappear… the river. For example, on the Kiev — Odessa highway signs with the names of small waterways exist, but they are not. They are either overgrown with weeds or completely gone underground. Continue reading
