3 Shrimp Farming Techniques and Their Characteristics

 

 

Description: shrimp farming techniques have advantages, disadvantages, and environmental impact. Here are three common techniques and their characteristics.

 

The rising demand for shrimps has encouraged farmers to start shrimp farming. Around 84 percent of the world’s shrimp supplies come from shrimp farmers in Asia. The farming methods vary, from traditional to extreme-water techniques. Farmers choose the best methods that ensure the shrimps’ growth, depending on the locations.

 

Here are three common techniques of shrimp farming around the world.

 

1. Intensive Farming

Intensive farming is a popular method among small farmers in coastal areas. Farmers create “bio security” in their ponds to ensure a minimum amount of harvests to fulfill demands. Predator control methods, such as crab and bird protections, are important in this method. Intensive farming can be done all year round, with regular pellets as the main food sources.

This method ensures regular shrimp supplies, good for business. However, uncontrolled intensive farming may cause environmental damage, especially on water quality.

 

2. Biofloc Farming

Biofloc farming requires the presence of “biofloc”, or various living organisms such as bacteria, fungi, and algae. The biofloc needs to fulfill certain requirements to keep shrimps healthy. These organisms consume shrimp waste and uneaten foods. They also become nutritious additions to the shrimp’s feed.

Biofloc farming is more environmentally-friendly. The shrimp quality is also better, because biofloc may increase the immune system. However, this technology is expensive and unreliable in areas with poor electricity. Special training is needed to help farmers in creating this system.

 

3. Closed Recirculation Farming

Closed recirculation farming is a cheaper solution for environmentally-friendly method than biofloc. In this method, farmers install several components for the solid filter, culture pond, reservoir, denitrification area, and sludge discharge. With this method, waste water can be reused after being filtered.

Closed recirculation farming yields large harvests while reducing effluent water and farming area. However, since the system is more advanced than traditional intensive farming, farmers must prepare alarm and generator systems. Farmers must also receive special training.

Choosing proper shrimp farming technique is important to determine the best result (with minimum environmental impact). Interested in farming shrimps? Don’t forget to study the advantages and disadvantages of each method.
