Last summer I was collecting weeds for my insect insect study tank and a few days later these fellas were swimming about and they grew into this. I have no idea what kind of fish they are, possibly a carp of some sort. Anyone got any ideas?







I am assuming that the multicoloured fish is a mutant, I have about 30 of these two of which have the strange colours and no scales.


Hmmm,

This is only a guess and i have no evidence to confirm but i think the coloured fish is a common gold fish. i know it is not gold but gold fish can change colour and are often born dull colours, even black. I suppose a form of protection for young fish. They look like gold fish to me.

Like i say only a guess though.

The fully scaled fish looks very mush like a Crucian Carp, it has about the right number of scales on its lateral line (31 to 33). I would like to know weather it was a wild or garden pond the weed was taken from and a photo of its dorsal fin and i will be able to tell you for sure.

I think the scaled one is a common goldfish and the other possibly a shubumpkin of some sort. Again only speculation but im fairly sure about the goldfish .

The weed samples were taken from a stocked trout fishery in the North East. I `m led to believe this lake was once stocked as a corse fishery.

I have done a bit of digging and have to agree with chalky, it appears you have stumbled across a rarely seen wild gold fish.www.bristol-aquarists.org.uk/goldfish/common/common.htm

Look at the last fish on this page.

Regards Mick.

I Thought the bottom one was a shubunkin

not too sure now

Looks very much like a young shubunkin to me.They will freely interbreed with crucians and goldfish.some goldfish never turn but stay brown.
My old club had a lake full of crucian/goldfish crosses.Great big fan tails,just like a comet tailed goldfish but totally brown-they did't half fight as well

Now the plot thickens. If these guys are in an 80 acre trout lake with 99% no pike with say cormerant, heron, kingfisher trout and perch eating them. Taking into consideration unknown time factor, unknown number of breeding pairs, weed collectors and shot in the dark variable. Could these specimens be a food item worth tying? Possibly??




Could this be the reason for so many a sorry blank?

When hungry surely any fish would be!

I had a stocked loch at my old house and it contained Rainbows of around th 2-3 pound mark. I used to try various Pike flies in the loch to see how they fished and cast and on numerous occasions I had Rainbows hitting the flies.

These flies where some 6 to 9 inches long dressed on size 3/0 to 8/0 hooks..and normally Orange and Tellow..so yes..a goldfish would easy make a meal for a trout.

I don't thing people realise how vorocious a predator a Trout is. I have had 3 brownies over 10 pounds on Pike baits, the biggest being 14 pounds, and around 9 Rainbows, biggest 17 pounds, again on baits meant for Pike
