Keeping fish in a breeding net for a certain period of time is necessary to determine the gender of your fish. You will be performing a gender check to determine whether your fish are male or female. If they are not, you will have to decide whether to keep them as pets or food. You may wonder how long you should keep your fish in a breeding net and what methods you should use to determine gender. Let’s dive into the details.

The Difference In Sex Ratios
The average human body contains 46 chromosomes. Fish have 48 chromosomes, making them essentially identical to our own genetic makeup. This being said, there is a significant difference in how our two species interact and relate to one another.
- Females are generally more docile than males. This is because they don’t have as high a libido as males do. This makes it easier for humans to manage them.
- Females are also less aggressive, which makes it easier for humans to observe them and figure out their reproductive cycles.
- Males are generally larger than females; hence the reason females are often placed on the bottom in tanks to protect them from predators.
The above differences in behavior and appearance make it easier for humans to identify the gender of fish. This way, you can determine how long you should keep your fish in a breeding net. Here are some general guidelines.
Length Of Time To Keep Fish In Breeder Net
Many fish keepers keep their fish for a couple years before determining the gender. During this time, you will be able to interact with your fish and determine how docile (or aggressive) they are. You can also observe the changing colors of their body as they grow and develop. Once you have determined the gender, you will need to either release the fish or keep them as pets.
The decision to keep or release your fish is highly personal. You will have to decide what is more important to you: having a docile pet or something to eat?
How To Determine The Gender Of Fish
The first step in establishing the gender of your fish is by observing them under a microscope. You will need to look for specific differences between the two sexes.
- The anal fin on a male is slightly longer and more curved than on a female.
- The upper jaw of the fish is slightly longer in males than in females.
- The upper jaw of the fish is also wider in males than in females.
- The color and pattern of the body of the fish are also important considerations. If you see any differences between the two sexes, you can determine the gender. For example, the body of a male is generally more pointed than that of a female. (Pointedness is a general term used to describe the contour of a fish’s body.)
- Males have an additional pelvic fin that females do not have. If you are unsure of the gender of your fish, you can use this additional fin to help determine it.
- Do not expect your fish to act or look like typical fish. This is due to the fact that they have been bred for appearance rather than function.
If you keep fish in a community tank with other people, you can ask them to help you determine the gender. If you keep your fish in solitude, you can use a digital camera to photograph them from every angle. This is important because specific body parts and details can vary based on the angle in which you are photographing them. For example, the shape of the head will be different when viewed from above versus when viewed from the side. (Head measurements can also help determine gender.)
Once you have determined the gender of your fish, you need to decide whether to keep them as pets or food. If you decide to keep them as pets, you have the choice of either releasing them back into the wild when they are mature or keeping them as a pet.
If you decide to eat your fish, you will need to carefully consider what type of food to use. Most veterinarians will recommend that you choose foods that are low in cholesterol and fat. These are essential nutrients for your fish. Make sure that you are aware of the nutritional content of what you are feeding your fish. Some fish foods are very high in cholesterol and fat, which can cause health problems. The key is to choose foods that are healthy for your fish.
