How do fish get into new lakes?
Some lake residents are even descended from ancestors that crossed from one lake to another. While most fish can’t travel very far over the land, their eggs will survive for several hours out of water. When waterbirds come to lakes to feed, fish eggs might get stuck to their feathers, hitching a ride to the water’s surface.
“It’s not uncommon for people to find eggs in the lake, but it’s very rare for them to actually find the eggs,” said Dr. Michael J. O’Connor, a professor of biology at the University of Wisconsin-Madison and a co-author of the new study.
How do fish spawn in a pond?
The male fish will chase the females, leading up to the big moment when the female will rub her abdomen on the mat and release her eggs. The eggs will hatch within a few days after the males fertilize them.
The eggs hatch in about a week, and the fry will grow to about 1.5 inches in length. They will eat a variety of foods, including small crustaceans, small fish, worms, snails, crayfish, mollusks and other invertebrates.
How long does it take for fish to get used to a new pond?

How do fish get into quarries?
In these situations, it’d be easy for invertebrates or small fishes to simply swim from a lake or river to a nearby quarry. For one thing, fish can’t swim very fast, so they have to rely on their fins to propel them through the water.
They also need to be able to swim in a straight line, which means that they need a way to balance themselves on the bottom of the lake. When a fish swims, its tail acts as a rudder, allowing it to steer itself in the direction it wants to go.
If the tail is too long or too short, the fish will be unable to keep its balance, and it will end up swimming in circles instead of straight lines. In addition to this, many fish have fins that are too small to support their entire body weight, making it difficult for them to maintain their balance while swimming.
How do carp get into lakes?

- South korea
- New zeal
most of the world’s population of carp is found in China

How do you tell if there are catfish in a pond?
