Since the beginning of human history, the sea has generously provided some of the food needs of human societies. But humans have caused the destruction and scarcity of marine resources through overfishing and environmental degradation. On the other hand, the world’s population is growing day by day, and the food needs of this population are also growing. So, what is the solution? This is where aquaculture comes in to help mankind. Currently, the aquaculture industry is responsible for providing a large portion of the protein consumed by the world’s population. Fish, crabs, oysters, shrimp, etc. are some of the seafood cultivated around the world.

Shrimp is one of the most popular seafood. People love it because of its high protein, rich minerals, and unique taste. This delicious seafood is produced in different countries. Weather condition is a very important factor in shrimp farming. Farmers grow this aquatic animal during the warm seasons of the year.

In the usual method of shrimp farming, the season begins in late spring and ends in mid-fall. This process occurs annually.

In recent decades, farming has been done more than once a year in different parts of the world.

Farming shrimp twice a year means growing and harvesting shrimp in two periods of the year. This method is done by changing the production and growth cycle of the shrimp so that it can be harvested twice a year.

In this article, we will introduce the method of farming shrimp twice a year and its advantages and results.

Species used in farming shrimp twice a year

In this method, species such as Western White shrimp, Indian white shrimp, Tiger shrimp, etc. are used. Observations show that it is possible to breed Indian white shrimp two to three times a year. It is also possible to breed tiger shrimp once or twice a year for a period of 4-5 months.

Western White Shrimp is one of the most suitable species to breed twice a year due to its characteristics such as high adaptability, fast growth, and high density.

The process of farming shrimp twice a year

Its process begins with the selection of healthy and suitable post-larvae. After the post-larvae are transferred to the farm, they are first placed in special ponds (nurseries). In the nursery, suitable conditions for their growth should be provided. These conditions include water quality, appropriate environmental temperature, and good nutrition. After about 30 to 45 days, when the shrimp have reached the juvenile stage, they are transferred to the growing ponds to reach the desired size. They are then harvested.

The second period is done in the same way. First, the post-larvae are stored in special ponds (nurseries). Then, they are transferred to the growth ponds in the juvenile stage and harvested when they reach the appropriate size. It should be noted that in the second period, the storage of post-larvae in nurseries should be started 30-45 days before the harvesting of the first period.

When shrimp are farmed twice a year, the shrimp are cultivated in ponds for approximately 60 to 90 days in each period. The farming period varies depending on the shrimp species, environmental conditions, and farming methods.

Advantages of farming shrimp twice a year

There are a number of reasons why this system has been considered. One of the most important reasons is the ability to supply the product in months that are not available with the once-a-year growing method.

In addition, this method results in better disease management and reduces the risk of contamination. This is due to the use of special ponds (nurseries), which increases the possibility of controlling contamination and pathogens.

Farming shrimp twice a yearmethod brings more productivity and profit to shrimp farmers by increasing the amount of shrimp production per unit area.

In general, the results of farming shrimp twice a yearvary depending on several factors. The main factors are weather, nutrition, the technology used, etc. Moreover, by using this method, it is possible to achieve higher productivity, an increase in production, and a higher profit.

Which countries use farming shrimp twice a year?

Shrimp farming is done twice a year in different parts of the world. As mentioned above, weather conditions are very important in this method.

In the south of China, it is possible to use the two-stage breeding method; but in the north of this country, shrimp can only be cultivated once a year.

Thailand, Ecuador, Vietnam, and India are among the countries that use this method.

In the south of Iran, and especially in Bushehr province, it is possible to grow shrimp in 6-7 months of the year. Bushehr is one of the suitable areas for using this method. Considering that the selected species in Bushehr is western white shrimp, farming shrimp twice a year has favorable results.

It should be noted that shrimp can be farmed up to 3 times a year in regions of the world within 10 degrees of the equator.

Considering the positive results of this method for the farmers and the possibility of supplying the product in more months of the year, this method can be considered a win-win process for the producer and the consumer.

With the spread of this method in all places that have the necessary conditions, we will see the growth of the shrimp industry and we will reach a sustainable industry.
