Recently, I have been reading some scientific studies carried out in Japan. As you are aware, the Japanese have carried out a considerable amount of research on whales and in my opinion, for all the wrong reasons. It is common knowledge that whales and dolphins can communicate with each other. The research carried out has discovered a novel method of concentrating these animals into a relatively small area using sound. The spin off from this is that the Japanese have applied this to fish. They have managed to exploit this commercially, attracting large numbers of fish into a small area. The benefit of this is that one fishing boat can catch the same number of fish in a day that would normally take a number of boats days using traditional trawling. The "green" aspects are much less fuel used, fewer boats are required and less damage to the seabed.
Now to get to the point. The research carried out in Japan has shown that sound can be used in water to attract fish and works just as well in rivers. Mugamuchi have exclusive rights to this technology and have found that tuning the frequency can attract specific fish. I am fortunate in having connections with some of the scientific research team in Japan and I have been asked to test the equipment in Europe. So far the results have been encouraging to say the least. The equipment comprises a small sound generator, a 20m cable and a small weighted waterproof speaker. The speaker is "spodded" into the river in a position of your choice - no longer do you have to cast to fish in cramped snaggy swims, the fish will be attracted to where you cast the speaker. You have complete control. It has been shown that the device is effective for 100m downstream and 30m upstream and will concentrate any fish present into a very small area. The only thing required is a bait and; it's help yourself time. No need for attractants, glugs and throwing in loads of bait in different swims. Instead, find yourself somewhere pleasant to sit and where landing fish is easy. One tip, use barbless hooks to speed up matters, it doesn't matter if a few fish drop off, there'll be plenty more queuing up. Some people may think that this kit takes some of the fun out of fishing. I don't subscribe to this point of view, the more fish on the bank, the better in my opinion with the increased chance of a clonker and much less wasted time sitting on the bank in a swim that may not contain any fish. The downside is that those who like posting about tinkering with rigs, hooks, tactics etc. will become largely irrelevant and eventually, history. Books on conventional tactics will be consigned to dusty bookshelves or recycling banks. I shall be offering a limited number of acoustic kits to interested parties to field test. To be selected to trial a kit on your water, you will be required to write a short story of a memorable fishing experience and why you deserve to be selected to use the acoustic kit. BFW members will be asked to vote on the best three entries.
