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
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.
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
This original small fish from the family of needle can be considered one of the most unusual creatures of the sea. Unusual body shape resembling a figure of a horse from chess, the original bearing try. males, especially masking, nutrition and behavior — all these traits inherent in our black sea seahorses.
Currently there are about 30 species of seahorses that inhabit the coastal waters of tropical and subtropical seas. However, they are found in the North sea (off the southern coast of England).
In the Black and Azov seas inhabited the ridge, which ichthyologists are called a long name “seahorse spinner the black sea”, sometimes adding more “European”.
The original appearance of this fish in due time led to the fact that each tourist visiting the black sea coast, tried to take home as a souvenir instance a dried seahorse. In the 1980-early 1990-XX years, with some individuals hundreds of thousands of individuals skate, recreational areas (on the South coast) almost disappeared, so in 1994 the black sea seahorse included in the Red book of Ukraine, fishing is prohibited.
The shape (external structure). The name of the fish (“horse”) comes from this “horse” appearance of the Hippocampus. The head of the seahorse is at right angles to the body (this does not observed none of the other marine life). And fish able to move its head up and down — ability, motoroleriu almost all modern fish species. Continue reading
