Higher Income Through Correct Application of Salmon Farming Techniques

Salmon is a specialty fish in the world, especially salmon roe with economic value many times higher than meat. In Vietnam, farmed salmon is rainbow trout, also known as cold-water salmon. Only a few areas with favorable climate conditions can raise this fish, and at the same time, strict farming techniques must be applied to harvest and profit. So where can Vietnamese salmon be farmed? And salmon farming techniques Is it complicated? Please refer to the article below.

  1. Salmon pond

Currently, salmon farming is developed in a variety of different farming forms such as ponds, cages with flowing water. The equipment system for the pond must be invested with a water treatment tank, especially an aeration system, because this is one of the most necessary requirements when raising salmon. People can use air compressors, pumps to increase the amount of oxygen, in the tank there are some effervescent wires, effervescent fruits so that the air is evenly distributed in the water. Large flowing ponds can be used with water fans instead of aerators.

Another technique in the design of salmon ponds is a shading system because the sun will increase the temperature of the water. It is best to use a roof system or use a black nylon mesh. Salmon farming water must be extremely clean. In Vietnam, the two main water sources for salmon farming are surface water including streams and underground water. Water needs to be treated carefully before releasing fingerlings into farming.

People must regularly monitor the water temperature, dissolved oxygen must always be maintained above 6mg/l, avoiding the phenomenon of water being polluted due to a large amount of food, waste… because of the protein and fat content in salmon food. very high. If rearing in cages, it is necessary to clean the nets every 3 days and change the nets once a month to avoid causing disease. Making sure the water is clean and not cloudy is the most important thing to pay attention to.

Ensuring the temperature and oxygen saturation in the water is also important. With the farm without grid electricity, having to use generator power will often affect the aeration process in the summer, so it should be paid attention.

  1. Salmon food

Currently, salmon feed in our country is not self-produced. Farms have to import pellets in Finland. How to feed salmon as follows:

Using dry pellets (35-65% protein) and mixed with vitamin C, vitamin B1.

The rate of feeding fish is from 3.5% – 5% of the weight of fish in the pond

People need to record the process of feeding the fish, monitor the fish’s food consumption as well as whether the weight is growing according to the standards or not.

  1. Prevention and treatment for salmon

Salmon often suffer from fungal and parasitic diseases. People should prevent disease by taking regular salt baths every 2 weeks, 2% concentration for about 20-30 minutes.

After each rain, it is necessary to add dilute salt water. Cleaning of tanks, ponds and cages must be carried out extremely strictly, if subjective, fish will get sick and not achieve high meat quality.

  1. Salmon harvest

Salmon will be harvested with good care after 12-15 months with an average size of 1.5-1.8kg. The harvesting process must be gentle because the fish’s condition is weak, easily scratched and dead, reducing the economic value.
