Strugeon farm at home

Let's look what a sturgeon is, and what earn possibilities it give to us.

Such fish is very valuable for its caviar (there is a huge amount), incredibly delicious meat. Previously extraction was  a killing of female sturgeon, which reduced fish stock, fish farmers have now learned to breed and produce a valuable product even at home with a small investment.

There are various species of sturgeon that do not require salt water, so it can be bred in small ponds, pools, and even at home. Compare estimated prices for fish products per kg., If carp - $ 4, catfish - 4.5 $, trout - $ 11, the sturgeon - $ 18 per kg. Agree there is a significant difference in price!

Many people probably already know how to grow a fish, but they believe that it needs to build a huge sturgeon farm while incur significant capital investment.

In fact it is not. We may start this activity in your back garden . This requires space which area is nearly 30 square meters. Even if there is no suitable space you can build a greenhouse made of polycarbonate. You need to bring water, sewer, electricity, and you need to heat greenhouse (fish need at least +17C to be grown in the winter).

Home farm that with strugeon loks like this.

With that system it is always possible to increase output by adding more pools.

As for investment, you'll need about $ 3,000 for equipment and $ 1000 somewhere to purchase fingerlings, feed and other costs. Filters, basins, sediment and compressors is equipment that you need. Costs can be significantly reduced if equipment create with your own hands, such as bio-filter or pools of polypropylene. Swimming pool heaters can be created using heating cable (for underfloor heating) and placeing it under the pool. Special light is not necessary, because the sturgeon fish lies at the bottom and likes shade. You need a generator in case of power failure.

You can buy a food, but in time, when you gain an experience, you can feed your fish with our own production. It would be profitable for you.

For growing use 5 gram fingerling sturgeon. Usually fish are grown to 500-600, and is sold to restaurants. Grow to a larger size does not make sense, because it's harder to sell. Fingerling costs about 2-3 $., and is sold at 10-11$, while the cost of food, electricity and water is 3-5$, 5 profit. In area of 30 sq.m. in 6-9 months, you can grow up to 1 ton of fish.

Sturgeon can be sold to: the restaurants (according to statistics, a small restaurant consumes 50-60 kg. sturgeon in the month), shops, markets and supermarkets.

In addition to the cultivation and sale of this valuable fish you can, in future for business, keep a few individuals for growing fingerlings. In this case, you have no need to purchase fingerlings at the side.

Anti Wi-Fi Wallpaper

It is very difficult to find a place where is no Wi-Fi in big cities. There is no such place in residential areas. And if you own a Wi-Fi access point, then no one will ensure that your Wi-Fi password will be not hacked. If there is a signal - you can get an unauthorized access to it. This can be solved by blocking a signal within the premises. Will soon appear on the market specialized wallpaper.

Wallpaper that blocks Wi-Fi have a special pattern, the application of paint with silver. As reported by the developers, its figure does not let to translate a radio signal at range of 2.4 GHz. But at the same time, all other frequencies will not feel any interference, mobile phones, radios, and 3G/4G networks will operate normally. But if you put the wallpaper pattern to another pattern, you can lock and signals at other frequencies.

"At the moment the consumer wireless network has a relatively weak protection and hack is not too difficult. When covering the walls with such wallpaper, inside your Wi-Fi will work "with enthusiasm," but noone will connect from the street". Such screening is recommended to use wallpaper while finishing head offices and other facilities where confidentiality is important.

And if you do not want to be in the room where silver wallpaper with crystal ornaments is on the wall, you can stick on top of it other wallpaper, more nice looking - the effect will not go away. But do not forget that for the complete isolation of radio signal you must not forget about the ceiling, the floor, doors and ... windows.
