They spawn by a method known as broadcast spawning, where females and males release their eggs and sperm into the water column at the same time. This method increases the likelihood that the eggs will become fertilized and decreases the chances that fertilized eggs will be eaten by egg predators near the seafloor.
How do flounder fish mate?
Peacock flounders have a “harem” mating system, in which one male mates with multiple females. Several females have sub-territories within a male’s territory. On average, one male mates with 6 females.
How many babies do flounders have?
Depending on their size, females have between 460,000 and more than 4 million eggs. They release the eggs into the water column and the eggs hatch in waters of the continental shelf.
What is the life cycle of a flounder?
Life cycle: Summer flounder spawn at sea in the fall and winter. Currents and winds carry the larvae to coastal and estuarine nursery areas where they live for the first 18 to 20 months of their lives. Afterward, they move into the ocean where they mature and join migratory adult fish. The maximum age is 15.
How do sea fish reproduce?
The methods of reproduction in fishes are varied, but most fishes lay a large number of small eggs, fertilized and scattered outside of the body. The eggs of pelagic fishes usually remain suspended in the open water. Many shore and freshwater fishes lay eggs on the bottom or among plants. Some have adhesive eggs.
Can I keep a flounder as a pet?
For the most part, flounder are semi-aggressive fish and they need to be kept in very large aquariums. Do not keep these fish with any species small enough to be viewed as prey. The flounder is also known as a flatfish which is a fitting name because its body is laterally compressed and it lays on its side.
Are flounder born with eyes on one side?
Larval flounder are born with one eye on each side of their head, but as they grow from the larval to juvenile stage through metamorphosis, one eye migrates to the other side of the body. As a result, both eyes are then on the side which faces up.

What is a flounders favorite food?
In general, a flounder’s diet consists of shrimp, crabs, smaller flounder (fluke), and bait fish such as sardines, shad, mullet, and mud minnows.
How long can a flounder live out of water?
They can suffocate and die quickly without water (following three to four minutes of no gill movement), so it’s important that you don’t take them out unless the new water is ready for their transfer.
Where do flounder go in the winter?
Yes, you can catch flounder in the winter months but you will have to target them offshore or around near shore structure. Flounder move out into the Gulf of Mexico and the Atlantic Ocean in the winter to spawn so you might have to go offshore 30 or 40 miles to find them during the cooler months.
Why does flounder have eyes on one side?
Do you know why? Wikipedia explains “as an adult, a flounder changes its habits and camouflages itself by lying on the bottom of the ocean floor as protection against predators. As a result, the eyes are then on the side which faces up. The side to which the eyes migrate is dependent on the species type”.
What fish has 2 eyes on one side?

What fish reproduce asexually?
the Amazon molly
An international team of scientists has sequenced the genome of the Amazon molly, a fish that reproduces asexually. The researchers expected that the asexual organism would be at a genetic disadvantage, but the Amazon molly is thriving.
How long do fish stay pregnant?
As examples, the female swordtail and guppy will both give birth to anywhere from 20 to 100 live young after a gestation period of four to six weeks, and mollies will produce a brood of 20 to 60 live young after a gestation of six to 10 weeks.
Can flounder survive in freshwater?
Flounder have proven to thrive in pure fresh water and have pretty good cold tolerance. I personally have seen southern flounder thriving and growing nicely in fresh water ponds for several years running.
What is special about flounder?
The bottom side of the flounder is white while the topside is dark. This is a special adaptation called counter shading. It makes it harder for predators (animals that eat other animals) to see the flounder when it is swimming. Flounder can also change color to match the background.
Do flounder like fresh water?
Flounders are amazingly tolerant of variations in the salt content of water. They can be found living in the sea, they can be found living in estuaries where slat water meets fresh, and they can even be found (and caught) in the freshwater of rivers well away from the sea shore.
What’s the difference between a fluke and a flounder?
