This may sound crazy at first, but it is true. Fish and other aquatic creatures may already be living in a fresh pond (or one that refills after being dry for a while), but you may not be able to see them. The reason for this is that the water in the pond may be too salty to allow the fish to live in it.
The salt layer is called a brine layer, and it can be seen when you look closely at the surface of your pond. You can also see it if you take a close look at your fish’s gills. Brine layers are formed by the presence of organic matter, such as bacteria, algae, or other microorganisms. When these organisms die, they decompose and leave behind their organic waste.

How do fish get to landlocked 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. The fish eggs might get stuck to the birds’ feathers when they come to the lakes to feed.
“It’s not uncommon to find eggs on a bird’s wing,” said Dr. Michael J. O’Connor, a professor of biology at the University of Wisconsin-Madison, who has been studying the phenomenon for more than a decade.
How do ponds naturally occur?
Ponds form when water begins to fill in a depression in the ground. Plants start to grow on the bottom of the pond. The plants start to grow on the edge of the pond. Over time, the plants in and around the pond grow and eventually the entire pond is covered with plants.
Emergent ponds can be found in many places around the world, but they are most common in tropical and subtropical areas. They are often found along rivers, lakes, and streams. In some areas, the ponds are so deep that they can only be seen from the air.
Why do fish randomly appear in ponds?
A pond that forms near other ponds may get new fish from birds dropping their catch. The fur and feet of local animals may be washed off as they move from one pond to the next if the fish roe remains damp. Ponds may also be affected by changes in water chemistry.
For example, a pond may become more acidic as a result of a change in the water’s pH, or it may be more alkaline due to an increase in dissolved oxygen. These changes can affect the behavior of fish and other aquatic organisms, as well as the ability of aquatic plants and animals to grow.
Does fish come from the sky?
In a rare weather phenomenon known as’animal rain’, fish fell from the sky in a town hours after it was hit by heavy rain. The fish, which were caught by fishermen, were found floating in the water near the town of Krasnoyarsk, in Russia’s far north-east, according to local news website Komsomolskaya Pravda.
How do carp get into lakes?
The majority of modern introductions are the result of fishing. In the early 1900s, they were brought to North America from Asia. below)
- South korea
- New zeal
most of the world’s population of carp is found in China
Asian carp population is estimated to be as high as 1.5 million, while the North American population has been estimated as low as 300,000.
Why do fish fall from the sky?
The phenomenon of raining fish is believed to be the result of a rare meteorological phenomenon in which a water spout moving over water sucks up small creatures such as fish and frog, carrying them along until they lose their buoyancy and sink to the bottom of the ocean.
Do fish naturally occur in lakes?
Some of the most common fish found in lakes are tiny shiners:
- Lake trout
Many of these give food to people. The world’s water comes from lakes, which are an important part of the water cycle. Lakes are also a great place to see wildlife.
These animals and plants have evolved over millions of years to survive in a world that has changed dramatically over the course of human history. They are a testament to the power of nature and the ingenuity of man.
