Our unique Black sea

Our city Odessa is located on the best sea in the world. There are living animals that can’t cause great harm, it’s just not natural cataclysms.

Lovingly the black sea washes the shores of Russia, Ukraine, Romania, Bulgaria, Turkey and Georgia. It is connected with other seas through the Bosphorus and Dardanelles and the sea of Azov – Kerch Strait.

Our sea is not too big (in the world), but that is not the last place. With a total area of 422 000 km from North to South the sea stretches for 580 km and from East to West 1150 km, the biggest depth – 2210 m, the average – 1240 m.

The length of the coast around the Black sea – 3400 km Into the sea fall into 3 major rivers: the Danube, Dniester, Dnieper.

Known than the Black sea?

First, one of its exclusive feature is the total absence of life at depths greater than 150-200 m (although there are a few anaerobic bacteria), due to the fact that at this depth the water is saturated with hydrogen sulphide. Continue reading

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. Seriali hunt groups for small fish (anchovy, sardine, mackerel), moving quickly from one area to another. In South-East Asia, the juveniles of the amberjack specially podesheveyut networks in obstructed areas of the sea, because the taste of the meat of these fish are highly valued. In the waters of the Gulf of Peter the Great met earlier yellowtail two other species, Golden and yellowtail. Continue reading

Storage of catch

Retention of fish caught

Retention of fish requires the angler skilled and decisive action. Quite commonly, because of inexperience or even excessive shyness freshly caught fish beats the ground or the bottom of the boat beneath the feet of the angler. And when she finally manages to pick up for long-term storage in the load it won’t work anymore. And cooking qualities of fish are significantly reduced.

Almost all peaceful fish, regardless of size and weight, after removal from the water is captured firmly by the back of the Gill covers. The stronger beats and resists the fish, the stronger must be its capture. In this case, the angler must remember that if the fish is supposed to store in a CORF, it is possible to shift the grip towards the Gill covers, especially under the gills, is unacceptable. Conversely, if fish is urgently preparing for the pan and storage is not intended, the pressure on the gills adjacent to the cavity must be quite strong. Such capture allows you to easily remove the hook from the esophagus. In the future, the fish intended for evisceration, outbreaks were sacrificed and laid in a cool place.

Predatory fish

The angler should remember that all predatory fish weighing more than 2 kg, in addition to sharp, and inogda impressive in size, fangs and spiny top fin (perch), stacked, bent inwards the torso of the teeth (pike) and razor-sharp notches along the perimeter of the Gill covers (perch), and has a number of additional spines and spines on the Gill covers, Continue reading
