Fish farming is a method in which fish are raised in tanks or enclosures to be consumed as food.
☝️ This is how fish farming 🐟 may look like in the sea ☝️
Why do we do fish farming and not traditional farming?
- Fish farmers can control the age, size, health and quality of fish.
- It is possible to raise fish with desired characteristics through selective breeding.
- By controlling the number of fish to be raised, fish farming can reduce the risk of overfarming.
- There is a guaranteed regular supply of fish all year round.
- Fish farming is safer for fishermen than traditional farming.
Things to Consider for Fish Farming
- Since large numbers of fish are kept in a confined space, fish may fight with each other. To avoid the competition, fish may need to be separated into different compartments.
- Intraspecific predation: Competition between individual fish of the same species is prevented by separating fish of similar sizes and age.
- Interspecific predation: Competition between fish of different species is prevented by separating different species into different compartments.
- Potential disease or infection need to be controlled.
- Antibiotics can be used.
- Dead fish should be removed quickly.
- It is possible to use biological control to remove pests.
- The oxygen level in the water needs to be monitored.
- Water is filtered to remove any waste products, such as feces.
- Fish are fed frequently but in small amounts to allow rapid growth but prevent overeating. The diet is also rich in protein.
- Fish raised in fish farms may be the products of selective breeding, so it is possible to raise fish with desired characteristics, such as fish with larger size.
