Breeding fish in the pond

With the appearance of the garden pond there is an understandable desire to populate its inhabitants, and to contemplate his troubled life. If you do not do this on purpose, after a couple of months the reservoir is mastered by the water striders, Daphnia, snails, beetles predaceous diving beetles, larvae of dragonflies, leeches, frogs and even small fish – roach, bleak, upperka. If the fish didn’t start itself, you can bring a trifle from a nearby natural reservoir for the formation of a complete ecosystem pond. However, even these fish, despite their modest size, have good appetite and can cause significant harm to the precious aquatic vegetation, so first I have to make a choice between fish and plants, or be limited to those species that are not eaten by fish.

If you allow the size of the pond, you can pay attention to the larger representatives of ichthyofauna. Very attractive with their bright varied coloration and calm disposition Japanese koi . These gregarious fish often swim to the water surface and to person and gives pleasure to watch them. But are they “hooligans” – lift up the bottom sludge and damaging the plants. For the winter they need sufficient depth – not less than 2 m, or moving the pond in winter garden. So those who have not, have to choose local species.

Often used in many natural waters carp, crucian carp . perch . of these, the last is the most demanding of water quality. Bass are predators, and very voracious, per 1 kg of weight have 5 times more food eaten, so the course is all coastal wildlife – insects, crustaceans, larvae, leeches, and even their own young, except frogs and large tadpoles. Perch cleans the pond, unpretentious. Hunts during the day, so well seen at night drops to the bottom. Continue reading

The denizens of the deep

What is life in the dark, deprived of light the depths of the ocean? The deeper one penetrates into the sea the daylight is, the faster it weakens. A traveler in the depths of the ocean V. Beebe writes that the water in the upper 50 m green color, at the depth of 60 m is greenish-blue or blue-green, 180 m in her clear blue color, at 300 m is a weak blackish-blue. Even at a depth of 580 m Bib caught the last traces of light. Various devices with photographic plates, and more precisely with the help of photomultiplier cameras detected that the light penetrates into the ocean to a depth of 1500 m. Deeper no devices it not get it. But animals and deeper 1500 m. They exist here in complete darkness, in which only here and there the glimmer of ghostly lights cold “living light”. Even on the biggest depth of about 11 thousand m — you can find animals. At this depth, they feel a tremendous pressure.

Life on the sea bottom at a depth of 3-5 m In the center — luminous brittle star hitching a ride, a spider crab and cancer munidopsis. For them. — animals leading a sedentary lifestyle, sea feathers. Top left — red crustacean shrimp.

The oceanic environment is called the realm of monotony. This is particularly true with respect to the depths of the ocean. Here in the water there are almost no oscillations of temperature and salinity. In the depths of the ocean and on its bottom life compared to being coastal in thousands and tens of thousands of times poorer. At the coast the number of benthic animals are often expressed by hundreds of grams or even a few kilograms per square metre of seabed. And in the depths of the ocean is equal to the number of sometimes only a few milligrams on the same area of bottom. The density of plankton in the coastal waters reaches hundreds, sometimes thousands of milligrams per 1 m 3. but in the depths it is limited to milligrams or even fractions of a milligram. This is primarily due to the abundance of food, at the coast and the lack of it in the depths of the ocean. Continue reading
