Are you wondering, do fish get periods? You’re not alone! As a lifelong aquarium enthusiast, I’ve often marveled at the beauty and mystery of these underwater creatures.
But one question has always lingered in the back of my mind: do fish experience the same menstrual cycles as humans?
In this blog, we’ll dive deep into the truth about fish menstruation and explore the fascinating world of fish reproduction. So grab your scuba gear and join me on this journey of discovery!
Do fish have periods? Let’s find out!
Do fish have periods?
Many people are curious about whether fish experience periods in the same way that humans do.
The short answer is no. Fish do not have menstrual cycles like humans. Instead, they have reproductive cycles that involve the release of eggs or spawn, which is different from the monthly shedding of the uterine lining in humans. Different fish species reproduce differently, but none experience a menstrual cycle.
However, it is important to note that fish have ways of signaling when they are ready to breed.
For example, some species of fish change colour or exhibit other physical changes when they are ready to mate.
Similarly, some fish release pheromones or other chemical signals to attract a mate.
While these processes are not the same as a menstrual cycle, they do show that fish have their own ways of reproducing and maintaining their populations.
Do catfish have periods?
No, that’s not true. Catfish don’t have periods. Menstruation is a biological process that women have to deal with, and fish don’t have any of the anatomy or physiology that makes that possible.
Instead, catfish and other fish reproduce through external fertilization, where the male and female release their gametes (eggs and sperm) into the water to be fertilized.
Once the eggs hatch, they become baby catfish, which then grow up to become adults!
So, next time someone asks you does catfish have periods, you can tell them no!
Which fish have periods? Are there any fish that have periods?
That’s what I thought, too. Which fish has a menstrual cycle? Although there are many different fish species, they all share a common ancestor: a primitive creature that lived in the oceans millions of years ago.
Over time, these creatures evolved into the myriad of fish that we see today. But did they all evolve to have periods? Obviously, no. But, as mentioned earlier, some fish display similar reproductive behaviors that some people referred it to as “periods” or “menstrual cycles.”
For example, when a female clownfish lays eggs, her body begins to produce eggs until she has laid all of them and then stops producing them for several days. This process can be repeated several times before it is complete.
This behavior is similar to menstruation because both processes involve hormone changes that result in the release of eggs or blood from the reproductive tract.
Despite this, both processes differ in important ways. Menstruation involves hormone changes that only last for a few days or weeks, whereas spawning may occur over an entire lifetime!

What is the process of fish reproduction?
All right, let’s explore fish reproduction now. Generally, as you can see in the video, fish reproduce by releasing eggs into the water, where male fish fertilize them. In turn, the eggs hatch into larvae, which grow into adult fish.
Some fish reproduce multiple times throughout their lives, while others only reproduce once in a lifetime. Depending on the species, some fish lay their eggs in nests, while others release them into the water.
Also, some fish care for their young, while others abandon them. The reproductive cycle of a fish can vary greatly depending on the species, but they all share the common goal of continuing their species.
Typically, the average female fish go through five main stages during their reproductive cycle:
There are a variety of reproductive strategies that fish use to ensure that their offspring survive. Some fish lay thousands of eggs and hope a few survive. While other fish are more selective and only lay a few eggs, but they take care of them until they are ready to hatch.
So, no matter what type of reproductive cycle a fish has, it is always an amazing sight to see them swimming and spawning in the wild.
How often do fish reproduce?
Female fish generally produce eggs once a year, but the frequency they reproduce can vary greatly depending on the species.
For example, some fish may only reproduce every other year, while others may reproduce multiple times throughout the year.
The number of eggs produced also varies, with some fish releasing hundreds or even thousands of eggs simultaneously while others may only produce a few dozen.
Do you know what triggers the fish to spawn?
There are different theories on how fish spawn, but the most likely explanation is that fish are sensitive to changes in water temperature and daylight hours.
As water temperatures rise and daylight hours lengthen, fish become more active and begin to spawn. Spawning typically occurs in the spring and summer months when water temperatures are at their highest.
However, it is thought that the fish’s Pineal gland, which is located in the brain, is involved in this process.
The Pineal gland is known to be sensitive to changes in light exposure, and it is thought that this may be how fish can detect changes in water temperature and daylight hours.
What is the gestation period for fish?
The gestation period for fish is the time between the egg’s fertilization and the young’s birth. This can vary greatly between species and even between different populations of the same species.
For example, the gestation period for salmon can range from 45 to 75 days. Some fish, such as sturgeon, can take up to several months to gestate. Usually, it takes three to six weeks. Factors that can affect the gestation period include:
- The size and age of the mother.
- The number of eggs she is carrying.
- The temperature of the water.
- The availability of food.
Do fish spend most of their time in estrus?
Estrus is the phase of the reproductive cycle when female animals are most receptive to mating. In fish, estrus typically lasts for just a few days each month. In fact, they only enter estrus for a brief period of time when they are ready to mate.
This is known as the spawning season. During this time, fish are more active and aggressive, and they may compete with each other for mates. After the spawning season, the fish return to their normal behaviour patterns.
However, some fish species may spend more time in estrus than others. For example, salmon may spend several weeks in estrus during spawning. In general, though, fish do not spend a great deal of time in estrus compared to other animals.
If fish don’t get periods, then which animals get periods?
Some animals have periods, such as primates, bats, and elephant shrews. For animals like these, the length of their period is directly related to their reproductive cycle. For example, a female chimpanzee will have a period of about 35 days, while a female elephant’s period can last up to six weeks.
Interestingly enough, scientists still debate whether animals experience menstrual cramps and other symptoms similar to humans.
However, it is generally accepted that animals do experience some form of discomfort or bleeding during their periods.
Overall, the period is a natural and necessary part of the reproductive cycle for some animals. Without it, these animals would be unable to reproduce and continue their species.
Final thoughts on Do fish get periods!
Do Fish Have Periods? After examining the literature and interacting with experts, we can confidently conclude that while fish may not experience a monthly cycle like humans, they probably experience some of the same hormonal changes.
Fish are fascinating creatures with a lot of cool adaptations! And if you’re interested in learning more about fish, there’s plenty of research on them being done all the time.
That’s all; thank you for reading this article! I hope you found it useful. Also, we’ve got some interesting FAQs about do fish have periods down below, so make sure you check them out!
FAQs related to (Do fish have periods!)
Q1. Do mermaids get periods?
Ans: It is believed that mermaids are mythical creatures that do not exist in real life. Therefore, it’s impossible for them to get periods.
Q2. Do sharks have periods?
Ans: Sharks do not have periods because they are fish. They are cold-blooded, which means their body temperature is the same as their surroundings. Fish do not have a menstrual cycle like humans, so they don’t have periods.
Q3. Do whales get periods?
Ans: No, whales do not get periods. They are mammals, but they do not menstruate like humans do.
Q4. Do skatefish have periods?
Ans: Skate fish do not have periods. As oviparous animals, they lay eggs. Their eggs are fertilized internally or externally, and then the young hatch from the egg sac.
Q5. Do flounder fish have periods?
Ans: Flounder fish is a type of flatfish, and they do not have periods. A period is monthly bleeding that occurs in humans and other animals with uteruses. Flounder fish are oviparous, meaning they lay eggs instead of giving birth to live young.
