Successful farming of salmon on Da Chais mountain

Bringing salmon seed originated in Northern Europe to successfully cultivate in K'long K'lanh village, Da Chais commune, Lac Duong, the land has more than 90% of ethnic minorities living, it is a miracle that Lam Dong province did.

Salmon farm is only about 55 km from Dalat center, located on provincial road 723 connecting Da Lat city with Nha Trang city. In addition, we are Mr. Nguyen Viet Thuy - Fisheries Engineer, Head of Quang Hiep Fish Breeding Experimental Station (under the Research Institute of Aquaculture No. 3), who directly implements and implements fish farming projects. cold water (invested by Lam Dong Department of Agriculture and Rural Development).

Mr. Thuy said, the journey to bring rainbow trout eggs, also called salmon (scientific name, Onchorynchus Mykis) from Finland to chill to grow into commercial fish in Vietnam, is a difficult process. .

Initially, the eggs must be imported and hatched, then hatched and finally released to the commercial pond. Currently in Lam Dong, only 2 stages have been carried out, such as nursery and grow-out. And the hatching stage of eggs is done in Sa Pa.

Sa Pa was the first locality of Vietnam to deploy salmon farming project in early 2005. After the locality successfully tested salmon farming, its attractiveness made Lam Dong provincial leaders and their communities. His work, going directly to Sa Pa in late 2005 to see the salmon farming model of Lao Cai people.

After that, it was determined to bring in Lam Dong to experiment with this promising fish for economic development. This is not without foundation when Lam Dong has much greater advantages than Sa Pa in terms of natural conditions, climate .

In April 2006, nearly 20,000 2-week-old salmon breeds were transported via air and road from Sa Pa to feed at Da Chais. Up to now, after 2 years of experimentation, salmon farming has resulted in unexpected success.

Lam Dong fishery sector in collaboration with Hoang Pho Co., Ltd. in Ho Chi Minh City, experimented to test salmon on Da Ma cold water stream, the fish weight reached an average of 1.2 kg / head, the productivity was estimated at 30 tons / ha, billion. The survival rate from nursery stage to finished product is 76.8%. At present, the cost of raising finished salmon products is from 63,000 to 67,000 VND / kg and the price of salmon products at the farm in Da Chais is 150,000 / kg.

According to Thuy's calculations, if raising properly technical process, take good care, farmers will have a profit of 30-40%. There are about 10 large restaurants and hotels in Da Lat, HCMC consuming rainbow trout raised in Da Chais, but the source of ' supply ' is still not commensurate with ' demand '.

Salmon is a popular dish

From the very positive and promising results of salmon farming, according to the leader of Lac Duong district, there are a lot of companies going to set up a salmon farming project at K'long K'lanh, Tuyen Lam lake and Da lake. Like Hoang Pho Company (invested VND 5 billion), Ha Quang Company in Ho Chi Minh City invested VND 8 billion, 7/5 Company invested VND 44 billion .

In particular, the Institute of Aquaculture No. 3 also set up a project to invest in a research center to produce coldwater fish varieties in Lam Dong with a budget of VND 15 billion.

As expected, by 2010 Lam Dong will have 50 hectares of water surface for cold-water fish farming, meeting domestic demand, instead of importing from Finland and Russia today.

According to statistics, each year Vietnam imports about 1,500 tons of salmon from Finland and Russia. The successful rainbow trout project in Lam Dong is opening up many prospects and soon we will no longer have to import and salmon will become popular all over the country.

An expert on aquaculture in Lam Dong said that salmon can live and grow well in the areas of Lac Duong, Dam Rong, areas near Dung K'Noi, and some places in Da Lat city - where there are cold water streams.

Currently, the price of salmon in Vietnam is still high due to not being able to actively breed and import from Finland. However, according to the Research Institute for Aquaculture No. 1 (Ministry of Agriculture and Rural Development), at the end of 2007 or early 2008, the Institute will be proactive in seed sources. In addition, research on processing and production of fish feed is also being actively implemented.

And if this is successful, the price of salmon sold to the market will be much cheaper. At that time, it was not only rich, rich "gods" who could eat salmon that even ordinary people could enjoy .

According to an expert on cold water fish, salmon farming requires a very strict farming regime, large capital investment, and even more hardship than taking care of babies.Water temperature in ponds and lakes must always be below 20 degrees Celsius. Water in ponds and lakes needs to have dissolved oxygen content to ensure that between 5.5 and 7mg / l, at least 3.5mg. / l.

Therefore, in addition to the regular water regime, the flow must be accompanied by a further criterion that water must be clean, upstream of streams.Every day, every half hour, I have to visit the lake once, regardless of whether it is rainy or windy.Fish waste is only fiber, so it almost does not affect the environment.
