What's going on?

[Andrew1002]

So I have been going to a spot on the Delaware River for roughly five years now and I go for fishing and my family swims there as well. But they swim on a different spot. I always get in the water to go fishing and look around and grab all the natural life I can to observe it. Never at all once did I see anything except large fish and tons of minnows. I'm talking 100000 minnows and fry. I went the other day to this same spot to find about 10 minnows, and no large fish. I started looking around on some of the rocks and I find a rock with about 100 snails on it and I start to look and see every rock was loaded with snails. Why are all the fish disappearing? We've always came at the same time of year so that can't be the problem. Are all the fish being out fished? And where did these snails come from?

Fairly simple answer to what you are seeing, those minnows are turning into snail. Snail fry looks like minnows until they form their shells which can take around 24 hours.

Correct me if I'm wrong but I believe that is what we call biological exponential growth. A simplified scenario can be, over fish the big fish. Minnow population explode. Big fish doesn't replenish itself quick enough to control minnows population so gradually minnows run out of food which is the snail. Minnows die off. Nothing left to eat snails so the snail population booms for a bit and the process repeats on a long term scale. Long term as in few years. I'm not an expert or a scientist and I am probably over stepping a lot of factors but I guess its a start
