Best squid jig colour

[quote name='Michael S K Chu' post='12186' date='Jun 21 2008, 09:44 PM']I do remember I had come across a TV programme (early this year or the year before) regarding the 'learning theory' of cuttle fish suggesting what cuttle fish would attack and what cuttle fish would not attack and treat something as prey or food. If I am not wrong, that should be one of the programmes in Discovery Channel.



That TV programme also told us that cuttle fish, squid and octupus were all colour-blinded. What they could see (with their eyes) were only black, white and grey. However, cuttle fish could simulate the background colour with the colour pigments on its skin. The programme showed that when cuttle fish swam to a particular region with a particular colour, it could change its colour pigments to match the same colour of that particular region (may be/or in order to protect itself). The experiment also showed that cutlle fish were particular sensitive to several combination of colour. I could not remeber the details. The experiment also showed that cuttle fish were insensitive to several combination of colour(yellow with ???, I forgot) and pattern of shapes in the background.



The TV programme also tells us that cuttlefish, squid and octupus have similar characteristics. I did not watch the whole programme, in fact. I only came across it. I did not know why they only chose cuttle fish for the experiment.



I then drew conclusion from their experiment that cuttle fish could actually 'understand' what the 'colour' was. It is not necessary for me, as squid angler, to know whether cuttle fish can understand what the 'colour' is by means of its 'eyes', or its pigments, or 'any part of its body'. Even the scientist who carried out the experiment did not know reason why. ...But... the outcome was that the cuttle fish could simulate the background colour with its pigments. So, cuttle fish must actually understood what the colour was before it could simulate and match that particular colour. The TV programme only showed the experiment on cuttle fish, it did not show identical experiment on squid. However, the programmes did tell us that cuttlefish, squid and octupus have similar characteristics, I further extend my 'conclusion' on squid that squid can also understand what the colour is before before it can change its colour to match the surrounding area(Remember, there was not any experiment on squid).



I then try to use my camera and take 'black and white pictures' of my favourite squid jigs trying to find out whether there is 'distinguished pattern' on them... carry out your own experiment and conclude your own results...



Up to this moment, I always try to gather squid jigs with 'big contrast' (whether expressed in terms of colour , pattern or shape).



It is indeed interesting to find out that every my fishing friends has its own favourite colour of squid jigs.



However, I think colour is not the final word,...... 'movement of the squid jig' is the key to sucess.

Note:

Cuttle fish and Octupus both live at the bottom of the sea and both do can camouflage. I doubt whether squid can camouflage. When in danger, squid produces black substance like ink and swims away quickly.



I doubt whether squid can distinguish colour as well.
