Among various nutrients, proteins stand out as an essential component for the development of aquatic organisms. Animal protein, in particular, possesses high biological value, meaning its amino acids are easily digested and utilized by fish bodies.

This characteristic makes it a fundamental nutrient in the diet of marine species. The absence or deficiency of proteins in the diet can lead to various health problems, such as stunted growth, poor tissue formation, and increased susceptibility to diseases.

Given the relevance of this topic, this content will detail the main positive aspects of using animal protein to nourish marine species. Stay with us to learn more.

What is the aquaculture panorama in Brazil?

Before discussing the relevance of using animal proteins to nourish marine species, it is important to understand the panorama of aquaculture in the country.

According to the 2022 Peixe BR Fish Farming Yearbook, fish production in Brazil reached 841 thousand tons. The highlight was the 45% growth in tilapia production over 8 years, representing 63.5% of fish production in the national territory.

What is the importance of proteins?

We previously highlighted the expansion of aquaculture in the country. In this context, protein ingredients are very important as they help in the nutrition of marine species.

Proteins have a wide range of functions and are a fundamental nutrient. They are highly demanded for fish nutrition. For example, shrimp can demand up to 70% of this nutrient.

Considering the high demand for proteins, we can say that they help in the growth and development of fish. Additionally, the nutrient helps in the maintenance of animal tissues.

It is also worth noting that protein elements are fundamental for the transport of substances and help improve the immune system. Given these characteristics, it can be said that they are one of the most important elements in fish nutrition.

What are the benefits of using animal protein to nourish marine species?

There are indeed many benefits to using protein to nourish marine species. Among the main positive aspects are accelerated growth, improved immune system, and optimized meat quality.

Accelerated growth

The first positive aspect provided by proteins is the acceleration of the growth of marine species. Additionally, protein elements act in the construction and maintenance of fish tissues.

Improved immune system

Proteins also help improve the immune system, enhancing resistance against parasites and possible diseases.

Facilitates digestibility

One of the main benefits of using animal protein ingredients, especially hydrolyzed ones, in marine species nutrition is that they facilitate digestion. This is due to the low molecular mass of the chemical element. For this reason, the use of these elements increases the crude protein digestibility coefficient up to 89%.

Weight gain

Animal protein ingredients are also easily absorbed and metabolized, favoring weight gain and optimizing the feed conversion rate of fish.

Improved meat quality

Given these positive aspects mentioned, we can say that the use of these nutrients contributes to improving meat quality. They will be more nutritious and have better digestibility.

As can be seen, animal protein plays a crucial role in the nutrition of marine species, especially those with carnivorous diets. Its high biological value, with essential amino acids in ideal proportions, ensures healthy growth, development, and reproduction of fish.

Moreover, animal protein contributes to improved feed conversion and disease resistance, optimizing aquaculture production and profitability.

Considering these mentioned aspects, it is well worth using this nutrient in the nutrition of marine species.
