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.

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.

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.
