Use of fish hydrolysates in shrimp nutrition / NBG DigestaPro

Dear colleagues,

The growth and profitability of the aquaculture industry, especially in the production of Pacific white shrimp, has led to the search for sustainable and efficient alternatives for feeding these animals. One of these alternatives is fish hydrolysates.

What are fish hydrolysates?

Fish hydrolysates are products obtained by hydrolysis, a process that “cuts” the bonds between the amino acids that make up the protein. This process results in low molecular weight fractions that favor nutrient absorption, making them more digestible and improving functional properties such as attractiveness.

Benefits of fish hydrolysates in shrimp nutrition

Fish hydrolysates have been shown to be a potent attractant that increases the growth rate of shrimp by decreasing losses due to uneaten feed, reducing the feed conversion factor and, consequently, the cost of feeding.

In addition, fish-derived bioactive peptides have different physiological functions, mainly associated with cell signaling, causing structural, molecular and cellular changes with biological effects, such as antioxidant, antimicrobial and immunomodulatory.

Substitution of fishmeal by low-dose fish hydrolysates

With the growing interest in formulating aquafeeds based on plant proteins and alternative sources to replace fishmeal, marine protein hydrolysates have emerged as a very promising solution.

Results from recent studies show that fish hydrolysates can be used at low doses to replace high percentages of fishmeal in shrimp diets, maintaining good growth performance, welfare and body chemistry, and digestive enzyme activity.

In addition, fish hydrolysates support hepatopancreas development and increase beneficial gut bacteria.

NBG DigestaPro

At Nutribiogenics we have developed NBG DigestaPro, a fish hydrolysate in which we have taken the utmost care to preserve the bioactive peptides thanks to the precise combination of a targeted enzymatic hydrolysis process and an ultrafiltration process.

 

Conclusion

The use of fish hydrolysates in shrimp nutrition offers a very interesting alternative for the aquaculture industry. As the demand for shrimp continues to grow, it is essential to explore and adopt these alternatives to ensure the sustainability and profitability of the industry.
