1. First, choose a breeding place. For freshwater breeding, you can go to the freshwater area to get some fresh water for breeding. Then try not to pollute the breeding place too much, otherwise it will not be suitable for the growth of salmon.

2. The breeding area should be large. If the area is too small, it will be very unsuitable for the growth of salmon. A larger breeding area is not only suitable for the growth of salmon, but can also increase the output of salmon farming.

3. Then choose the fish food to feed. If you are not very good at preparing fish ingredients, you can choose salmon ingredients that you have prepared yourself. There are many on the market, just buy the ones that match.

4. Then pay attention to the oxygen content in the water. If the oxygen content is too low, it is very unsuitable for the growth of salmon. So pay attention to ventilation and water changes to create a good living environment for salmon.

5. Pay attention to the sun and light. Too much light time and too high water temperature are not suitable for the growth of salmon. Pay attention to sunshade measures to prevent the water temperature from being too high.

6. Finally, when selecting salmon fry, don’t pick one that is too big or too small, as this is not conducive to growth.

Reproduction methods

During the breeding season, sexually mature salmon will flock back to the river where they were born to spawn. The female's strong tail will slap the water between the gravel to create a backflow, and then dig a pit in the river bed to build a "nest". Female fish and male fish will lay eggs and emit sperm respectively in the upper reaches of the pit. The female will use her tail again to stir up gravel to cover the eggs and sperm in the pit. Atlantic salmon breed multiple times, meaning they do not die after spawning. Instead, they return to the ocean to recuperate and then swim back into the river to spawn again the next year.

Nutritional value

Salmon is rich in nutrients and unsaturated fatty acids. The protein in the fish contains 18 amino acids (including 8 essential amino acids for the human body), and the protein content is significantly high. For other fish? . In addition, salmon is also rich in various minerals (such as calcium, phosphorus, magnesium, etc.).
