do fish see in colour and how good is there vision.?

Question

just wondering really if they do or dont,ive kept this qustion to my self for years and just been pondering on it whist sat fishing.

Answer 1

Most fish have color vision. The distance a fish can see underwater depends on water clarity. some fish can see 100 feet or more in very clear water, though a more likely range for lake dwelling fish is 10 to 20 feet.

Fish view the outside world through a window in the water surface. The diameter is about twice as wide as the fish is deep. In other words, a fish 5 feet deep would have a window 10 feet in diameter. Because the of the way light rays bend when they enter the water, fish can see objects above water that are far to the side of the window.

A fish's eye placement gives them a wide field of vision. They can see in all directions except straight down and straight back. Depth perception and 3-d vision is possible by looking directly ahead viewing the object with both eyes. Otherwise it only has 2-d vision since it is viewing an object with only one eye.

Answer 2

I've seen definite differences in how fish react to lures of different colors. Several times I've seen yellowtail biting brown & white jigs (several different models) while they ignored the blue & white ones (in the same several models); other times the exact opposite. I'm sure other people have noted this with other species of fish and other lures.

Of course, how far they can see depends on water clarity, and what the colors look like depend on the depth (red appears gray pretty close to the surface (maybe 50 feet in the ocean) while blue will still look blue at 2 or 3 times that depth). But as far as a fisherman is concerned, yes, they can see in color and lure color can and often does make a difference.

Answer 3

I am no expert on fish , just so you know. but my experience with some fish say yes they do. the bass fish is a hunter under water, and so color does help in deciding whether to eat or not, along with movement of said item this bass was looking at. As far as eye sight, also very good. in clear water near the bank of a lake, the bass is very alert. I mainly fish for catfish, and they taste, and smell with their skin. with 27,000, taste buds, or near about, you may not have to have real good eyesight. As far as all fish , really do not know, but good question. hope this helps.

Answer 4

Fish do see in colour. Their vision is Trichromatic, which is the same as humans. Most fish have pretty good vision, when compared to a human's vision in an under-water environment.

Answer 5

it is obvious fish can see in colour, some fish are very colourful, this to show other fish they are dangerous to eat.

Some fish change colour when ready to mate. So they must be able to see in colour!

Answer 6

fish do see in color thats why they make fishing lures in SO many color variations.
their vision is ok, but most fish like catfish go by smell and some other types go by their hearing(rattling lure)

Answer 7

being a sea fisherman i hunt some species who hunt by sight like Bass and have used different coloured beads for Plaice ,dabs and other flatfish so i like to think all my experimenting with coloured beads and shiny lures is not all in vain

Answer 8

Fish can definitely see in color because changing the color of your bait can generate strikes.

Answer 9

its a good question it brings to my mind the myth or fact of dogs seeing in black and white, now we just have to find nemo and ask him to take a opthalmology exam and we will know the answer!

Answer 10
