Eight Ways to Clear Pond Wild Fish

Wild fish breeding in the pond, there is no commercial value, but also compete with the fish for oxygen consumption, affecting the pond aquaculture production and economic benefits, commonly used methods of removal are the following eight. 1, completely clear pond. Before fry stocking, drain pool water, clear the pond with quicklime, strong chlorine and other drugs, completely kill wild fish, snails, aquatic insects, bacteria and parasites, etc., which are very good for stocking fry. 2, water filtration. Water filtration can effectively control the amount of wild fish. Especially for fry and fingerling ponds, the influent should generally be filtered, and the filter meshes should be made of polyethylene or gauze material with a 2 mm mesh, which can be used to stop miscellaneous fish, eggs and aquatic insects. Fish fry can also be placed in a cage. The fry can be filtered with a screen that is slightly larger than the fish's body. Most of the fish that cannot be sieved are wild fish and can be buried. 3, exposure of aquatic plants. When fish ponds are fed with aquatic plants, first expose the plants to the sun for 1-2 hours, or soak the plants in 5 mg/L copper sulphate solution for 2 hours to kill the fish eggs and small mites attached to aquatic plants. shrimp. 4, set the fish nest. In the fish breeding season, fish roots are set in the fish ponds with root water plants to allow wild fish to spawn in the fish nests. It was found that fish eggs were attached to the fish nest and the fish nest was removed and removed in time. Or when the wild fish spawn on the fish nest, spill the drugs such as trichlorfon and quicklime to kill the eggs. 5, biological removal. Fish ponds with a large amount of adulterated fish, or fish ponds with a second-generation fishery, can use ferocity black fish, squid, and leather beard to remove trash and shrimp. Ponds must be able to catch fish in dry ponds in order to control the number of ferocious fish so as not to cause harm. Mixed ferocious fish, specifications should be less than two-thirds of the fish, not more than 40 each time, otherwise it will harm the fish. 6, around the wild fish. In the fish growing season, the whole pool or some fish ponds are caught and caught, so that the fish pools are concentrated in the net in a short period of time. As the wild fish suffocation point is lower than that of domestic fish, most of them will suffocate and die in a short time. After most of the wild fish die, the fish will be returned to the pool. 7, mixed carnivorous fish. Mixed carp, squid, stingray, bigmouth bass and other carnivorous fishes in the pond can not only eliminate wild miscellaneous fish, but also produce some high-quality fish and improve the efficiency of pond culture. 8, suffocation method. Wild fish consumes more oxygen than home fish. Using the method of reducing dissolved oxygen content, you can suffocate the wild fry and leave fry. The specific approach is to install half a bucket of water and put a mixture of fry. As the fry are intensive and the oxygen consumption increases rapidly, the wild fish collides and faints, and then they die one after another. Home fry is also disturbed by lack of oxygen. In a few moments, it floats on the water and gets into a group. At this time, pots were used to leave clustered fry in another bucket filled with fresh water, and sank to the bottom of the water. The wild fish fry were dead. If the wild fry are not yet removed, and (may) take the second suffocation, until the wild fish die.

Metatron Hunter 4025 Purpose:

The Metapathia-GR Hunter software can operate only with the telemetric nonlinear analysis data processing apparatus "Metatron" and its subsequent modifications. The telemetric nonlinear analysis data processing device is compatible with the IBM-type PCs and intended for studying reaction of a biological object to different types of the informational impact. "Metatron" allows correlating the measurement process with the process
affecting it and performs the following operations:

1) It measures J (0) which mirrors the change of the describing parameter, and the entropic potential relative to its initial value;
2) It transforms continuous signal J (0) with the preset intervals of frequencies into a histogram (a row of numerical values of scanned frequencies with serial numbers from 1.8 to 8.2 Hz.);
3) It sends the current W values to PC and displays the graph on the monitor simultaneously with its impact on the examinee.
4) It accumulates the W value in its memory unit, if observing the histogram is more convenient upon completion of the measurements;
5) It issues the scale-correlated commands required for regulating the effect on the examinee at testing;
6) It transmits the W values from the unit into PC memory upon completion of the measurements and saves them in unit memory of prior to the
beginning of recording data of the next measurements.
