Recently, while on #LinkedIn, I came across an inspiring post from an aquaculture specialist named
Mohamed Nasr who shared his personal journey after completing the FAO course on "Aquatic Food By-Product Valorisation."
His post not only showcased his newfound expertise but also revealed how sustainable value addition can transform everyday fish by-products into high-value products. I was so impressed that I had to share it with you all, along with some insights on how you too can turn innovative ideas into profit.

A Glimpse into the Specialist’s Journey
In his post, the specialist detailed his experience with the #FAO course, which equipped him with a deep understanding of efficiently utilizing fish resources. His key takeaway? Value addition is the future of sustainable aquaculture.
He introduced a fascinating product called #FishSilage. Here's a quick summary of what he shared:
What is Fish Silage?
> Fish Silage is a liquid or semi-solid product made from fish waste—such as heads, guts, bones, scales, and fins—through a controlled biological breakdown. Using acids or enzymes, this process preserves the material and enhances its digestibility, making it a nutrient-rich feed for animals or even for further processing in aquaculture.
How to Manufacture Fish Silage
1. Selecting Raw Materials: Choose fresh fish by-products to avoid microbial contamination.
2. Grinding and Chopping: Break down the waste into small pieces for better additive reaction.
3. Adding Preservatives:
*Acid Silage Process:* Use organic acids (like formic, propionic, or lactic acid) to lower the pH below 4, preventing harmful bacteria from growing.
*Enzymatic Silage Process:* Employ natural enzymes for a more sustainable, chemical-free option, albeit with a longer processing time.
4. Mixing and Fermentation: Stir the mixture regularly in a sealed container for 7-14 days at an optimal temperature of 25-35°C.
5. Filtration and Storage: Filter out larger particles to obtain a uniform product, which can last up to 6 months at room temperature (or even longer if refrigerated).
Usage
- Ideal for incorporation into feeds for fish, poultry, and livestock.
- Can be blended with other protein sources to balance amino acid profiles.
Why Choose Fish Silage?
- Environmentally Sustainable
- Cost-Effective
- Nutrient-Rich
- Versatile

Why This Matters to You
The specialist’s post is a powerful reminder that **value addition is not just a trend—it's a game changer**.
By rethinking how we utilize fish by-products, we can:
-Increase profitability: Turn what was once considered waste into a lucrative product.
- Promote sustainability: Reduce environmental impact by efficiently using resources.
- Create new markets: Open up diverse revenue streams from traditional aquaculture operations.
