Iron - Electrofishing and brakanerstvo.
[] S. Filimonov With Vladimir Loskutnikova I met through the Internet, taking part in one of ehokonferentsy. There are devices, although quite easy to implement, but the validity of which is in serious doubt - Here's a topic that we discussed. One such device is devoted to article, written by Vladimir specifically for "Optron. Electrofishing and poaching {} Vladimir Loskutnikov, 1999 Life is learning from death all close our eyes. Felix Krivine "We need a scheme Electrofishing" - appeared in relkom.radio. Responded to many. Intense discussion ensued. We give the most Interesting quote. "In an e-winter fishing rod - a simple multivibrator and an electromagnet, jerking rod. Collect this adjustable frequency from 1 to 10 Hz can be any "radiogubitel. "Electrofishing is a converter 12 in the 300-400 VDC current capacity of 50-100 uF and terminal pulse generator for thyristors with a frequency of 5-100 Hz. The effect is achieved paralysis of all living within a radius of 1-2 m from "Fisherman". "Rybachat" with the Boats, the best ordinary, rather than rubber. And to call this device it would be better - "elektrosachok. "It's not Electrofishing and elektroubiytsa! How long will it be enough after those who are already poor, water! " "It not only creates a high voltage, but also generated sawtooth pulses. They affect dezorientiruyusche fish, and that as a stray pops up on Sachyok is a positive electrode. And as near the nets fish gets its portion of electric shock, which temporarily paralyzes her. If the 20-30 with no time it catch, she wakes up and reeled. True, fry up to 2-3 cm alive not always. So tackle this course poaching. But it is effective only on shallow water, and where the fish - in bulk. " "But we caught the two grief-elektrorybakov - threw them through the power lines and wiring - the wiser ... The result: the posting annihilate, from the depths of the Dnieper surfaced about 2 tonnes of fish, and transformers substation flew. Well, at least for yourself Heads did not turn. " "In the spring of old women with a rotten fish see? Zamorenye ponds, ponds that are drained, ponds and lakes that turn into swamps, and where, apart from duckweed - only rotten Water? So, the fall of these places fish You can rake cleaned by any means - without damage to nature. Another thing spawning grounds ... " On the admissibility of such devaysov could "flame" for a long time - and each will remain in my opinion. Of course, poaching - it is unacceptable. But this is what is meant by the term - a very slippery question. It is clear that there must be prohibited any gear, allowing maintenance crippled fish. And what about the rest? If you are a member of society "Hunters and anglers," then you can catch ten rods at a time, and if not, it was only five. Zakinesh six fishing rods - and you're a poacher! A net and seine net? Now any citizen Russia can buy (and relatively expensive) license to fish net (footage not specified, there is money - by becoming even 10km) at any time, at least for a period of spawning! And not a single inspector is not entitled to terminate this catch! But if the supply chain 10 m without a license - then you are already a poacher. Even if it takes place in July and 100 m kilometer network of fishing cooperative. There is also a different approach: there are tackles that are forbidden only for the fact that they You can catch more fish! For example, koltsovki - type zakidushki combined with a trough. And in France, for example, banned Night fishing on zakidushki (acne on their well-caught). I do this to ensure that the legislative definition of "poacher" somewhat slyly. Fishing artels widely throughout Russia apply the so-called "Elektronevod, moreover, at least ten years. This - the usual net, but let down voltage for paralyzing the fish with his approach - that it should not run away. Net, let it be known, has a working width of several hundred meters. My personal opinion - an army of 100 singles with any gear (even with dynamite) is not compared to damage by up to one modest official rybartelyu! What there quotas and rules! Caught all year round spawn - not a hindrance. The funny thing is that they do not listen to the recommendations of Ichthyologists and themselves and suffer the same - catch disastrous decline. What is this if not legalized poaching? Take our Verhneuralsk reservoir: width - from 1 to 5 km, length - about 20 km, depth - 5-20 meters Several passes seine in the summer, and - in winter perch caught no bigger than 50 grams, and perch, even petty - virtually disappeared. How's that for scale? When the collective farm in connection with the visit foreign delegations gave the order to catch 10 perch length of 1 m, a week, they dragged a seine over the pond, and caught only 3 pieces. No comment ... (I will not say about other "miracles", which gets up our "glorious" fishing control!) A "Electrofishing - no more than a copy "Elektronevoda," only instead of the seine - Sachyok small radius of paralyzing immeasurably less. And it appeared later "Elektronevoda. Witnessed experiments in aquarium fishes. Not fatally - by 1-2 minutes is already moving, completely depart 15-20 minutes. In this case, electric fish received much stronger than in the real conditions - the distance between the electrodes was only 0.5 m. "Electrofishing" do not injure the fish, unlike, say, dynamite. For umervschleniya fish need to raise or power (For some reason it is very difficult to raise above 100-200 W), or time of current flow (if the battery "dies" the maximum 20 min, as current consumption - 15-30 A). In addition, the operation "Electrofishing" very laborious. All (I know) of those who attempted to engage in "elektrorybalkoy" dropped the case after the second or third times. So - let the guys do. Harm will no longer be a radio technician slightly learn. Personally, I think that "Electrofishing is not justified. This mining tackle, such as network or kiddle dragnet. If the fish in the pond there, then on the network in 40 m catch more than 2 hours with this "Rod" (a larger battery is rarely enough). Network is much easier to operate - no batteries, no risk of getting a good electric shock, no transistors, which like to burn. Because - Self-indulgence! Only where there is a reason - in waters with depths of up to 2 meters, fully overgrown vegetation. But such is not so much. A river does not recommend - fish after "elektrorybalki" simply go into other places. In contrast to the same network, which does not scare away the fish. (Sam-I I love to fish with a fishing rod.) So "Electrofishing" in most cases - a waste of effort, time and funds. Instead of the same items would be better to make the power supply (from 12 - 20-40) for high-power automotive amplifier. Useful and safe! >
