Among infectious diseases most common diseases of bacterial origin: aeromonosis and Pseudomonas.
Aeromonosis.The causative agent is aeromonad – motile gram-negative bacteria p. Aeromonas (A. hydrophila, A. sobria) related to SEM. Vibrionaceae. Hits all the main types of pond fish (carp, white Amur, carp, crucian carp). The factors contributing to the development of fish are the sharp increase in water temperature, low fatness of the fish, dense planting, poor feeding, high content of organic matter, the trauma to the fish.
Aeromonosis is acute, subacute and chronic. The acute form is observed in the spring and summer and can be accompanied by mass death of fish (70%). The disease manifests itself in the form of serous-hemorrhagic inflammation of the skin and is characterized by edema, ekzoftalm, enlarged abdomen, aresenium scales. At autopsy in the abdominal cavity detect the exudates (clear, yellowish or bloody fluid), peritonitis, hemorrhagic inflammation of the intestines, degeneration of the internal organs (increase, discoloration, foci of necrosis).

Red sea – an inland sea of the Indian ocean situated between the Arabian Peninsula and Africa. For the inner sea depth here is very high – more than 3000 meters, as this sea lies in a tectonic break. The Red sea is not no river flows (around deserts), and therefore the water is exceptionally clean.
Off the coast of Egypt water temperature even in winter does not fall below +20 degrees, and in summer rises to +27. Due to the heat evaporates much water, causing the salinity of the red sea reaches 38-42 grams of salts per liter.
In this sea are ideal conditions for underwater flora and fauna. There are about a thousand species of fish, including endemic species, and about 150 species of corals. The coral reef extends directly along the shore, and near them go to schools of fish of most unimaginable colors and shapes.
In the Northern hemisphere there’s no better scuba diving than the coast of Hurghada, Safaga, El Gouna, Sharm El Sheikh, Ein Sukhna, Marsa El Alam. Diving Safari – long trips on boats and yachts in the southern and Northern areas of the red sea. The term “Safari” means a cruise ship with multiple dives in the most interesting points of the sea’s many Islands, atolls, coral reefs and sunken ships. Continue reading
Japanese cuisine has become so popular in the former USSR, and perhaps in deaf villages appear sushi bars and restaurants. Is there (in the sense is there and can it is) “our” Japanese cuisine is still an open question, but with traditional products, this world-famous culinary school will learn is worth it! Among its more exotic products perhaps the most outlandish is flying fish ROE – tobiko.
Marine fish from the family of Flying fish are included in the squad of Organoborane. The collection includes about eighty species, with a common distinctive feature: the ability to perform hovering flight above the waves thanks to the peculiar structure of the body and internal organs.
All flying fish live in tropical seas with a water temperature not below 20-23 degrees. The greatest diversity of species occurs in the Indian ocean and the Western Pacific. Some species are found only in the coastal zone, while others prefer the open ocean. They gather in small flocks that are kept near the water surface. They feed on small sea animals, of fish larvae, plankton. Breed of small red-orange caviar, with a diameter not exceeding 0.8 mm, which is attached to algae or any floating object. Continue reading
