If the pond is large enough and its depth is more than 1.5 meters, then all its citizens can be safely left in place, through some measures to ensure their safety. Before freezing the water in the pond is saturated with oxygen, and the fish it would be enough for a long time. But the dead leaves of aquatic plants and the waste products of the fish will decompose in cold water and allocate detrimental to the inhabitants of the marsh gas pond.

For saturation of water with oxygen and removal of marsh gas must be cut in the ice hole and to ensure that they did not freeze. In no event it is impossible to break the ice with a hammer or other object. From the strong sound waves can hurt the fish.

To make the hole carefully and all the rules, you can use a simple way, taking a small metal container and adding hot water to gradually melt the ice. You can use the screws – a special device for ice fishing. Keep in mind that the thickness of the ice in the cold if your pond does not covered and will be 40-60 cm

During the winter as little as possible disturb the fish. At low temperatures water pond inhabitants fall into sostoianiia rest (hibernation) and are located at the bottom of the pond. The fish stops feeding and consumes less oxygen. Continue reading

Fish from marine reserves are not characteristic caution

One of the species of fish-surgeons ( Naso vlamingii ), the inhabitants of coral reefs. Figure out in Nature

It is known that fish living in marine reserves, the larger and more prolific than their counterparts in unprotected areas. Australian biologists have shown that, in addition, fish from reserves more trusting and therefore easier to catch. And when you consider that the fish constantly slips out of reserves to unprotected waters, this information can serve as an argument in favor of the establishment of marine reserves.

Long time was considered that the protection of individual sections of the World ocean cannot be effective because of its global reach and “openness”. But it gradually became clear that the ocean is not only global but also local effects of man. As examples of the latter can lead to construction in the coastal zone, the deepening of navigation channels, poorly regulated fisheries, wild life, etc. To protect against local influences began to create so-called marine reserves — marine protected area. Now there are more than 3000. One of the main goals of marine reserves is to provide safe and supportive in all respects of space for growing food fish.

Loginoremail that the fish in these reserves live longer, on average, grow to a significant size and leave more offspring than fish in unguarded water areas. It is natural to expect that some fish larvae, and adults, out of the reserves into surrounding unprotected areas. Indeed, the scientists showed that of the reserve located within the Great barrier reef. from 55 to 83% of juvenile percoid distributed around the reserve unguarded waters. Continue reading
