Seaweed and shrimp farming

Table of Contents

Imagine the underwater world. Besides fish and shrimp, what other marine life can you name? Even with a complete knowledge of the underwater environment, the vast and amazing diversity of aquatic species makes it a challenge to name each one.

As you know, many different types of plants live in the oceans. Seaweed is one of these plants that can be found on a large scale in the oceans. When we talk about seaweed, what comes to mind is green seaweed. However, the truth is that seaweed also comes in colors like red and brown.

Seaweed does not have roots. Instead, it has an organ called a holdfast that allows it to stick to the ocean floor.

Seaweed has a part called the blade that allows it to absorb light more effectively. In some seaweed, the reproductive part is also on the blade.

Seaweed lives in shallow areas of the ocean where there is some soil to stick to.

Different uses of seaweed

Seaweed has a wide range of uses, from human consumption to industrial applications.

In the distant past, some East Asians used seaweed as food. This trend continues today. Nowadays, European and American countries also use seaweed as food. In Japan, seaweed is used as a popular ingredient in food.

The next use of seaweed is in animal and poultry feed. Seaweed is usually used as a powder in pet food.

For agricultural products, seaweed is also used as a fertilizer. Due to its mineral content, it promotes growth and increases the resistance of crops.

Seaweed is widely used in industrial applications. Its high content of polysaccharides is the main reason for its use in industry. They are used in the food industry such as ice cream and chocolate. It is also used in health and beauty products. Canning and meat industries and bacterial research are other uses of seaweed.

The use of seaweed in shrimp farming

The growing aquaculture industry is looking for a fishmeal replacement. Fishmeal is one of the most vital feed sources for aquatic animals, which has been declining in recent years. Seaweed is one of the suitable substitutes for fishmeal.

Seaweed is a good source of minerals, vitamins, proteins, amino acids, etc. Various studies have determined the effect of seaweed in improving aquatic feeds.

The use of seaweed in shrimp feed has beneficial effects that are discussed below.

The use of seaweed powder in shrimp feed increases shrimp growth. Depending on the type of seaweed and the age of the shrimp, the effectiveness of seaweed powder on shrimp growth will vary.

Shrimp resistance is also increased by using seaweed powder in shrimp feed. The compounds in seaweed powder, such as alginate, boost shrimp immunity and increase their disease resistance.

Another positive feature of using seaweed powders in shrimp feed is the reduction in feed conversion ratio. Studies have shown that the use of seaweed powders such as Ulva can reduce the feed conversion ratio. As shrimp feed is expensive for the farmer, reducing the feed conversion ratio can be an important motivation for using seaweed powders in shrimp feed.

The benefits of using seaweed powder in shrimp feed do not end there.

Other benefits of seaweed include improving plate quality, shrimp metabolism, and pigmentation.

Of course, the optimal use of seaweed powder in shrimp feed is essential to achieve positive results. Overuse of seaweed powder can be detrimental.

Each type of seaweed has different characteristics. Depending on the desired objective, one type or a combination of them should be used in the shrimp feed.

Seaweed farming has become one of the most important branches of aquaculture due to the various industrial uses of seaweed and its proven benefits as a feed for aquatic animals. China is one of the largest producers of edible seaweed in the world, producing millions of tons of seaweed each year. Japan, China, and America are major importers of seaweed. Statistics predict a bright future for seaweed farming.
