FISH ID PLEASE

[AR577]

If there are plants, amphibians, insects and other insects in a body of water the fish isn't a pioneer species.

Birds are responsible for the transfer of lots of different fish. Many fish transverse and live in puddles like killifish and eels. It doesn't make them a pioneer species.

Green sunfish is a pioneer fish species, because they're first fish species to appeared in new areas. You can arguing all you want, but I've found more green sunfish than any fish species in isolated fishless ponds.

But it seems that you have a problem with using pioneer term to describe a first species arrived in the new area to colonize. It is not uncommon that the first fish species are usually green sunfish or fathead minnows or red belly daces.

I was thinking you have the same problem.

If you dump bleach into a pond killing all the organisms green sunfish will not be the first species to establish a population unless it produces it own food. It will be different species of worms and other aquatic insects. Why you don't think the different species of plants and smaller inverts a species is beyond me.

I don't know what else to tell you other than get an introductory to biology textbook.

Still....the fact remains that green sunfish is the first fish species to arrived in new area. You took this too serious.

The sunfish seemed large to me, but again, I don't how large they get. It was around 6 inches, and had a pretty beefy bulldog look to it.

What is your theory on how they got there? Just curious. There are a few populations of green sunfish here in Maine now. No one seems to know where they came from. I've only seen one live specimen, but it didn't look anything like the photo in the beginning of this thread.

In your situation, it was most likely bait dumps. But....I had few large ponds completely isolated on private property that had green sunfish and daces appeared from nowhere. We do not stock anything since these ponds are pretty shallow & prone to winterkills and intended to be watering pool for livestock. My suspect were probably birds.

Sunfish eggs can get stuck to the feet of waterbirds and be transported that way, or strands of waterweed with entangled eggs can also be carried that way. Theoretically a turtle or frog could do the same, if it came from a nearby pond.
Also, I've heard a couple of stories of green sunfish traveling overland during floods- they can swim laying sideways in just an inch or two of water if they want to, even the big ones. The bitty ones can move very long distances in just a trace of water, as long as they're covered or mostly covered while laying on their side.

We call them "bucket biologists". That is how pike have spread through out this state. So far the green sunfish seemed to be contained to one river drainage.
Although possible that birds and/or other animals can spread fish eggs, IMO it is more likely that people have spread fishes around.
