Using UV Lights To Attract Squids

[Mr_Typhoon]

Hi,



i want t know if anybody as ever used UV lights to attract squids?

I think that type of light will interfer with them.



Many thanks

As far as I know the lights used on squid boats are UV , I have read where squid boats take out tourists and give them hats to wear while the lights are on to protect them from UV burns

Hi supersquid,



Many thanks for your information, but do you know anything about using those lights underwater?



where in Portugal we use Fluorescent lamps, like those we use in our houses or offices.



I've tried to use in the past night a dark UV lamp underwater but the weather was very bad for squids, so the experience didn't work as I planned.



If you could get me some more tips I'll be thankfull



Keep on the good fishing

As far as I know, the main lamps used for commercial squid fishing are either Metal Halide Fishing Lamp or Halogen Fishing Lamps.



Here is a quote from the samsunglitec site -

Halogen Fishing Underwater Lamp

●● Small size, long life & no blackness.

●● Resistant to high water pressure, made of double bulbs.

●● Controlled luminosity in the range of 0∼220V by voltage sliders.

●● Resistant to water pressure by 35kg/cm2, using UH-Type lamp holders.



Metal Halide Underwater Lamp

●● Small size, high efficiency & long life.

●● Green, blue, and white color.

●● Controlled luminosity by voltage sliders.

●● Resistant to water pressure by 35kg/cm2, using UH-Type lamp holders.

I am not sure which ones put out more UV, or if indeed UV is that important.



Do squid actually see UV light? I will try to look into this a bit for you. It sounds familiar..I am pretty sure I have seen some scientific articles about this topic.

Hi Glen,



Maybe I didn't express in the correct terms.

What I want to say is the lamp I was bought is a dark light, like those used in discotheques.



Many thks

hi ricardo...sorry i am not sure what you mean by "dark" light.



how do you know the thing is even working if its all dark!? <img src='http://www.squidfish.net/forums/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt=':th' /> have you got any info about the manufacturer perhaps? I could try to look into further for you.

UV light should be ok. Squid don't like bright light.



I'm doing here on Langkawi fishing, and for this I always need to catch squid for bait. Normaly we use here a gasoline Lamp (as Coleman, Petromax or Butterfly) The light output is about 400 Watt, and is slightly yellow colored.



We hang the lamp about 1/2 meter over the water and use a quiver to get the squid. Using this format you need to get the squid from behind.



The lamp actualy attract small fishes and with this the squids as they go for the small fish.

hi mazdev, what is a quiver? <img src='http://www.squidfish.net/forums/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='' />

Hi Glen,

I think the light he is talking about is commonly referred to as a "Black Light". It is similar to a standard fluorescent light fixture (long tubes). There are two different main types of "this type" of Ultra Violet UV light. The main difference is that one has a white bulb, that emits visible light, the other has a black colored coating that filters out the visible light, and only lets through the invisible Ultra Violet light. I use a "Black Light" in my office to charge up glow in the dark items. For all glow in the dark LUMINOUS items, UV Ultra Violet light is required to provide a charge so that they will glow. The more UV light, the faster and better charge.



Personally, I think a visible type of light is necessary, but I could be wrong.

hi jon, i got the impression the quiver was a rod or net or something like that. it seems to be separate from the lamp?



thanks for the extra info about black lights. i didn't know they were good for charging luminous objects! i will keep it in mind.

Hi Glen,

The quiver sounds like some sort of gaff that they snag the squid when they can't see it coming.



Regarding the black lights, they work great!!! BUT!!! only if they are big enough. I have tried the small hand held ones, and they really don't put out enough UV to properly charge anything. Anything that glows in the dark requires UV light to make it glow. Just about every light source will provide UV, but not at the same levels. For instance a halogen light puts out UV, but a (Metal Halide, Mercury Vapor, or High Pressure Sodium) puts out much higher levels of UV for the same power output. They even make filters for the large Metal Halide lights to make them a black light, a black light is only light that has good UV output, but with a black filter to block out the visible light. I think they use a lot of those really big black lights for theatre stages.



In my own squid fishing setup. I have a 12 Volt auto battery with a power inverter, and all of this put inside of a portable box. Then I mount an 18 inch fluorescent style black light. This way I can take it to the pier at night and charge my jigs. The other fishermen get SOOOO excited when I open my box and they see hundreds of super glowing squid jigs inside.

The quiver is a 2 meter rod with a net. The squids will come to the surface where we catch them with the quiver (you must catch them from behind). To make it more complex, the first squid we got, we will put a hook carefully at the backside and will tight this hook with a string under the lamp, so the squid will attract other squids to come. On some nights we catch about 70 kg squid this way.



About the light. The light is gasoline lantern (coleman, Petromax or Butterfly) the type you need to pump. It has nothing to do with Black light. For every one knowing this type will know that the light is more a yellow light. The Lantern will hang about 1/2 meter above the sea.



Ypu also can use spot lights using a generator. Output should be 400 Watt.

thanks for the info guys,



i might have to give that "live squid on a hook method" a go one of these days. sounds very effective.



cheers, glen
