21. Aquarium extreme ecosystem: deep-sea trenches

.
THE OCEAN DEEP UNKNOWN

Angela heaven? Nooo!, Deep-sea creatures

seek life on other worlds and forget that our planet still has large areas to discover. In the deep sea abyssal pits covering 80% of the ocean has been explored and only 1% of these depths.

We're really talking about an ecosystem could well belong to another planet, since it has little to do with what we know. A world of eternal darkness without the sun, half submerged in water devoid of nutrients, the temperature between 0 º - 4 º C and ambient pressure unthinkable x 1 ton cubic cm. Despite these impossible conditions, there is life.

The existence of minimal organic matter produced by bacteria that are maintaining biomass through chemosynthesis (cover your needs carbon at the expense of bicarbonate ion, oxidizing ammonia, hydrogen, nitrite, methane or inorganic substances).

Because of this lack of food, has developed a balance based on the absolute predation between creatures and the arrival of animals or dead plants in the upper layers that fall as a blessing from heaven (allochthonous food, ie source different from the living environment).

creatures of the darkness sentences are extremely long-lived and slow live saving energy, including the immense silence and immobility of unguarded current environment. It's the closest thing to live in intergalactic space. During endless hours

remain fixed as statues, and just before the need to flee, eat or play, activate their muscles gelatinous to lazily move without harmony or balance.

living things are little studied. With every dive Expeditionary are discovered ten new species. Some creatures have evolved as spectacular light through bioluminescence, which is discovering what is served, or to hunt as a trap to attract prey, or to find couples of the same species.

In the cold substrate
soil reaches a depth of up to 11,000 km tiny brightly colored roving bodies dragged seeking shelter and food awaited.

not effected by high pressure, are sponges with open cavities where water can stay here in large communities. His fate is that they are a food prized by other living beings. There is a type of sponge that looks like spun glass prisms, thanks to its textured woven silica fibers.

mean abyssal pits still a mystery, as scientists estimate that remains to be discovered more than 95% of the species that live there.

creation of an aquarium ABYSSAL

Can abyssal aquarium? This question I have made several people and it is difficult to answer with scientific rigor. The human being is able to manage to finally achieve his goal and in this case, if we play the same conditions as in the deep sea as it would clearly be viable. Not so much financially.

What are these conditions?

1. The tank should be sturdy enough to withstand water under a pressure of 1 ton x cm ³. Precisely bathyscaphes or submarines entering these depths support these pressures. Its construction is usually done with concrete and titanium alloys. Thus, we should build something like a submarine with windows but with a reverse order to hold water inside.

2. For get this constant pressure in the water, they should design a powered hydraulic pistons to push water into the tank. A mechanism must be precise and powerful that can be anchored to deliver the result we want: 1 ton x cm ³.

3. must have a good filtering system, although the water to be poor in nutrients and so cold in theory kept clean. The conditions of the deep trenches are similar to those of bottled water in the sense that it moves in the absence of currents. Anyway, it would be interesting to experiment with a kind of sump or space where you can enter chemosynthetic autotrophic bacteria (autoproducer and consumers of nutrients) and heterotrophic (feeding on dung and carrion from the abyss).

4. Keep chilled water in a constant temperature between 1 º and 4 º C.

5. occasion not to stress the animals are kept, it is important that the tank was hidden opaque to light, and as much, has windows to see inside. In the deep darkness reigns, except in the very animals that produce bioluminescence. The internally illuminated by fiber optics would be most appropriate because of the inordinate pressure on the lights implode. With fiber optic light source can be calculated from the outside, adjusting it to the best conditions.

6. most interesting species to keep are the most striking: those that produce light. In theory, we should keep only one predator species by nature. Few creatures are known to occupy large areas. On the other hand, their status as food economy and extremely low production of excretions would make easier to maintain.

extreme ecosystems These experiments offer 2 very important reasons to take Term:

a. means a step forward in studying the exotic and unknown deep-sea species behavior in these extreme conditions for us, under continuous observation.
b. help us better understand the different possibilities in life forms, is essential to investigate the possibility of alien life in distant worlds inhabited (exobiology).

schemes were designed to understand how this tank should be unfathomable.

NOTE: As these issues are complex and require much imagination, other questions assail me basic the introduction or removal of these creatures in the aquarium. Should always be handled under pressure. The only thing that comes to mind is captured with resistant sealed containers that are open systems, lock and access as the hatch of spacecraft or submarines. Animals being so slow, fishing is supposed to be simple.
