When a Rag worm is put on a hook, or when a snail falls into a lake - Amino Acids slowly leak from them, creating a scent trail that fish use to help find their next meal. If you say to a dog 'treat' or something similar, they will get excited and wait in anticipation for the food, give a fish some amino acids and they'll be expecting food in the same way.
Then there's the less well known 'Bile Acids'. Bile Acids are excreted by fish after feeding and when released into the water - other fish will search that area for food too, often creating a feeding frenzy.
Isome contains both of these acids, essentially creating a scent which not only attracts fish - but also gets them in the mood for feeding! What more could you want? Oh yes... No longer shall you suffer from the stench of bait, but will instead go home smelling something like genetically sweetened grape juice!
Now we've covered the two main ingredients that go into the Isome Juice (as I call it), we can move on, to how the lure releases these ingredients into the surrounding water. Marukyu (power) Isome are made from plastic, but they feel like no other soft plastic on the market. They are especially made to absorb the fluid they come with, and without it, will shrivel up and become useless. This means that they will never lose their scent, and continue to smell delicious for ages. Isome are also 100% biodegradable and completely edible to fish, so once a fish has bitten off a chunk, they'll keep coming back for more. This results with much more hook ups than with 'normal' lures and in turn is really good for the environment.
One man told me "The lure releases more amino acids when bitten into which means a fish will hit the lure multiple times if there is no hook up initially." I'd like to describe this as the 'sponge effect' (because it sounds cool) and you can really experience this in all it's glory when sight fishing abroad. In the Canary Islands Will and I were being plagued by Puffer fish which would inhale the Isome and then exhale out a bare hook. We striked at the bites and had a few hook ups, but even after being hooked several times these elusive fish would still come back again and again, bewitched by the scent/taste of Isome.
- If overused at small fresh water marks, fish may become wise to them, and start to associate the scent with danger, rather than food. (This time it would be like offering a dog a treat, and then poking it in the eye... eventually they would learn to associate 'treat' with pain)
- Don't get too addicted! If you always fish with Isome, you won't learn some important techniques, and consequently just like a heroine addict, you'll be so hooked on the stuff, that you will be dependant on it! If you want to stick with this type of lure though, try out the Ecogear Aqua range. It follows the same principles as Isome, but will add some variety to your fishing.
Don't over work them, too much action on these lures may put certain fish species off. Especially in Winter or when targeting mini species.
Of course, you don't need to understand your lures, to catch fish. But for those OCD 'must understand everything' people like me - I hope this has helped!
