Inland Shrimp Farming

Table of Contents

Shrimp farming began many years ago in East Asian coastal communities in a completely traditional manner. There have been many changes in the methods and practices of shrimp farming since its inception. The shrimp aquaculture industry has been able to keep pace with technological developments, which is why shrimp aquaculture is not only sustainable but also growing significantly. Looking at the history of the industry, shrimp farming has evolved from traditional and extensive methods to intensive and super-intensive methods, and industry proponents have adopted new methods to increase efficiency. In recent years, inland shrimp farming has emerged as an important solution for providing protein in areas where access to water resources is limited. In this method, shrimp are typically grown in closed environments such as ponds or water reservoirs.

Inland shrimp farming has grown significantly in recent years. Initially, it was common in Asian countries with black tiger shrimp. Later, it expanded significantly with the introduction of Pacific white shrimp or Vannamei. For example, a significant portion of China’s farmed shrimp production is grown in inland and freshwater areas. It is also widely used in countries such as Thailand, Vietnam, and Indonesia. In recent years, inland shrimp farming has also gained popularity in Western countries, and there are currently several shrimp farms in various countries, including the United States of America.

This cultivation method is very attractive due to its advantages such as better control of environmental conditions, prevention of contact with hazardous factors in the water, and greater efficiency in the use of water resources. In addition, since the cultivation environment is controlled, this process can ultimately contribute to reducing the negative impact on the environment.

Depending on environmental conditions and project needs, different types of ponds and water reservoirs are commonly used in inland shrimp farming. The following are some of the different types of ponds and water reservoirs used in this method:

– Plastic ponds: This pond is made of a lightweight plastic material and is usually used as a portable pond that can be set up in a variety of locations.

– Concrete ponds: These ponds are made of concrete and are typically used for larger and permanent projects.

– High-capacity water reservoirs: These ponds are usually made of concrete, fiberglass, or other water-resistant materials and are suitable for large and industrial projects.

Why inland shrimp farming?

Why do farmers choose inland shrimp farming? There are several reasons for choosing inland shrimp farming. The main reasons are:

-Reducing dependence on natural resources: The use of shrimp farming in inland ponds and reservoirs offers the possibility of shrimp farming in places where access to natural resources is limited.

– Biological safety: One of the most important reasons for using this method is to increase biosecurity and improve control of common shrimp diseases compared to coastal areas. The issue of biosecurity is very important in the shrimp farming industry as various viral and bacterial diseases cause many problems for this industry worldwide every year.

– Better control of environmental conditions: In this method, environmental conditions such as temperature, light, oxygen, and water salinity can be precisely controlled, which can help improve growth and productivity in shrimp farming.

– Optimal management of water resources: The use of water reservoirs and artificial ponds in this method allows to optimize water consumption and use less water resources.

– Job creation and economic development: Inland shrimp farming can create employment and income opportunities for youth and local people and contribute to the region’s economic development.

– Improved product quality: Controlled conditions in reservoirs and ponds can improve the quality of the final product, such as the size, taste, and texture of the shrimp.

In addition, inland shrimp farming significantly reduces the need for water changes and by shortening the growing season, increases the possibility of shrimp farming to two or three times a year.

Required technologies

One of the new aquaculture methods is inland shrimp farming. To be efficient and sustainable, this method requires the use of modern technologies and new methods. Some of the technologies used in inland shrimp farming are:

– Water purification systems: These systems are essential in this method to maintain water quality and control pollution.

– Aeration systems: It is necessary to create appropriate environmental conditions, including temperature and oxygen, and prevent the accumulation of organic matter through aeration systems.

– Water Access Control: These systems are used to manage water resources and improve efficiency.

– Intelligent Monitoring and Control: These systems monitor and control various environmental parameters in ponds and water reservoirs.

– Optimal feeding: The use of modern technology in this field can lead to a reduction in wastage and an improvement in the growth and health of the shrimp.

In general, inland shrimp farming is an advanced activity that requires technical knowledge and experience in environmental management and control.

Environmental issues

So far, we have discussed inland shrimp farming, the reasons for using it, and the benefits it brings. But this is only part of the story; there are several environmental concerns that farmers should consider and solve before using this method.

Shrimp farms, which are located far from the coast, should put the reuse of the water they use on the agenda and prevent polluted effluent from entering natural waters. Water reuse systems must include water treatment tanks to improve water quality.

Shrimp farm sediments should not be discharged outside the farm. These sediments contain amounts of salt that can affect the water and soil in the area after rainfall. To prevent this water from flowing into neighboring fields, it is recommended that farmers use a shallow ditch around the field.

Shrimp farms should be located in areas where the soil has enough particles to resist seepage and prevent salinization. Environmental experts recommend the establishment of a vegetation cover around the farms; the health of this vegetation is an indication that the surface soil is not saline.
