In the Atlantic ocean, the Black sea and off the coast of India dwells amazing and a bit scary fish monkfish .With it is associated a very curious phenomenon. For a long time researchers could not understand why all the water harvested from fish of this species are invariably females. As they multiplied.
Only after the beginning of the heavy deep-sea studies have found out that monkfish has developed a unique mechanism of reproduction. It turned out that the male and female fish monkfish differ in size a thousand times. The female is a large part of his life spent in the coastal zone and can grow up to two meters long, and the male also reaches only a few centimeters and lives at great depths, where is the justice in this world = ( . This was established when he was discovered living at depths of more than two hundred meters tiny fish acerated. Caught deep-sea dredges of acaracide were always males. Only after painstaking research revealed that acerated is (many readers probably already guessed it) a male sea devil, and not a separate species or a subspecies.
To find such a small male helped another feature of the sea devil — the annual migration of huge females on the depth taken by them for the purpose of procreation. Continue reading
Did you know that eating marine fish prolongs life . All sea products and sea fish. especially salmon, tuna, sardines etc are rich in fatty acids omega – 3. Fish is the only product that does not confirm the rule “the less fat you have, the better!”
Fish oil . contains healthy omega – 3, protects the arteries, “thins the blood” such as aspirin to avoid blood clots. Fish oil reduces blood pressure and blood levels of dangerous fats.
If you want to preserve youth and prolong life need to eat more seafood, particularly fatty marine fish.
The most useful is considered salmon. In order to save the greatest amount of nutrients fish is not recommended to fry. It is better to pickle, bake or cook in their own juice without the addition of vegetable fats and mayonnaise. Continue reading
The content of the fish in a saltwater aquarium can be very challenging. Maintenance of the necessary salinity of the water and a sufficiently high oxygen level in it even in a well – equipped aquarium is not easy. Most marine fish bred in aquariums, is habitat, so these fish cannot tolerate fluctuations. Reef the oxygen level is always high and a lot of light, because the corals grow only in shallow and clean water.
Sea water is very corrosive, so the aquarium must be made entirely of glass or plastic, without metal parts. Although marine fish are less inclined to jump out of the vessel compared to freshwater, the aquarium must be carefully closed to avoid contamination. It will also help to control evaporation: when water evaporates, salinity increases, so the vessel should be topped up with distilled water.
Bright lighting is also important in a marine aquarium. It promotes the growth of algae, which clean the water and in turn may serve as food for fish. Seawater is a complex mixture of salts Continue reading
