What is a sea sponge?

Sponges that are sold in stores and are used for washing dishes or cleaning the kitchen, not real. They are made from synthetic materials, although very similar to a real sponge and easy to use.

But these sponges appear in the sea, not in a chemical laboratory. For a long time many were convinced that they know all about sponges. It was believed that this plant, until in 1825 a man by the name of Robert Grant proved that sponges were animals!

It considered the sponge in water through a microscope. And saw trickles of water, which went in through one hole and out through another. Still, for many years, scientists did not know what kind of animal. Thought it was a tiny single-celled creatures that live together in one big colony.

We now know that sponges are the dried skeletons of marine animals belonging to the class of “porous”. This is a pretty significant group of animals. Although sponges are one of the lowest forms in the animal Kingdom, their structure is quite complicated. Continue reading

How to make a pond for fish farming

There are many ways to create a pond to breed fish at home – as difficult, requiring a lot of physical and material costs, and simple and cheap.

Before you can create a pond for breeding fish, you should become familiar with the basic requirements to create an artificial pond.

Manual

1 the Pond should not be in the shade of trees or buildings, so it can be illuminated by the sun at least part of the day. It is best to create it among the flower beds and close to home. And if the choice of the shape of the reservoir can fully rely on imagination, the depth of the reservoir depends on its purpose. For example, hoping to leave the fish in the pond for the winter, need to build special wintering pits or wells. Continue reading

The inspection found the cause of mass death of fish in the Nikolaev reservoirs

From 11 to 19 June this year, the State ecological inspection in the Nikolaev area repeatedly documented fish kills in the rivers the southern bug, Ingul and the Bugsky estuary. In this regard, we selected 22 samples of water and held control for the major pollutants.

As reported in a press-state ecoinspection service in the Nikolaev area, in the surface layer recorded water dissolved oxygen for the entire period from 0.9 to 10.5 mg/DM 3. The ratio — during the summer, the oxygen content in all water bodies should be not less than 6,0 mg/dm3 .

The oxygen is released into the water column as a result of processes of photosynthesis, which better takes place in the daytime. At night there is a reverse process. Therefore, the minimum content of oxygen is observed at dawn, which was recorded on June 19, in 6 hours (the water temperature was 25 0 C). The concentration of dissolved oxygen ranged from 4.0 mg/DM 3 the water surface to 0.2 mg/dm3 in the bottom horizon. This fact is due to the hydrometeorological conditions prevailing in the present time, what is the likely cause of the phenomena zamorny. Continue reading
