The pond is an artificial pond created for fish breeding. For the construction of ponds it is best to use natural depressions, such as depressions and gullies. It is preferable to find such hollows near rivers, to avoid problems during the flooding of the ponds. Such ponds are called riparian. For the formation of floodplain ponds enough to block the earthworks elevated part of the shore. In front of an earthen embankment will be saved by river, atmospheric, ground water. In such ponds it is good to raise warm-water fish species.
In that case, if a future pond removed from river beds, it can be used other sources of flooding. Key ponds filled by water gushing from the ground up the keys, and brown – due to streams flowing across the land. Key ponds are created by the embankment and the strand by dividing creeks dams. These ponds are well used for the cultivation of Coldwater fish species.
Before you decide definitively on the choice of land where to locate the pond, it is necessary to conduct chemical analysis of water that will fill the pond. Water must be free from harmful impurities and chemical elements such as sulfur, chlorine, etc. Continue reading
MARINE AQUARIUM, a vessel for keeping marine animals and plants. Is usually large in size (200 litres), as its inhabitants usually larger than the inhabitants of freshwater aquariums.
Compared to freshwater marine aquarium is more time-consuming in use, since the secret of the successful maintenance of marine fish is the maintenance of conditions corresponding to their natural habitat. Often contain well-dressed inhabitants of tropical coral reefs. It is interesting to contain cold-water marine life. Such an aquarium should be in the summer especially cool.
Sea water is prepared artificially by division or from commercially available ready mixes for marine aquariums. It must have a salinity of 30-35‰, pH of 8.0 to 8.4, temperature depending on the content types. You need a constant control of temperature, pH, density (measured by hydrometer) and water salinity. Most dangerous is the accumulation of toxins in the water due to protein contamination. To combat protein contamination need a strong filtration system and water reclamation, as well as weekly substitution is not less than a quarter of the fresh water well preferirana water of the same density. The destruction of proteins contribute to aquarium lighting UV lamps and ozonation of water. Primenjajutsja special tools — catchers protein. Continue reading
Venezuela is one of the best and most visited places for sport fishing in the world. Here is a great opportunity, both for marine and for freshwater fishing.
Based on the opinions of most anglers, the best fishing occurs in Venezuela on lake Guri. Lake Guri is one of the largest artificial lakes in the world (about 175 km long and 48 km wide). It appeared in the construction of a dam on the river Caroni, a tributary of the great Orinoco. Favorable ecological situation and perfect conditions for fish to have made this place very popular among fishing enthusiasts from all over the world. Of special interest on the lake is fishing in a strong and aggressive tropical peacock bass pavón (average specimen weighs about 5 kg) and predatory fish Paru – distant relative of the piranha that inhabit the Amazon and Orinoco.
Another popular fishing spot in Venezuela is located in the district of waterfalls ARIMA (river Paragua), in the state of Bolivar in South-East of the country. Here you catch Paro and Aymara. It was here that they caught the largest specimen of Para (weight was 17.8 kg) and thus set a world record IGFA. The best time for fishing is from January to may. Continue reading
