In aquaculture, recent advances highlight the use of microalgae solutions in the cultivation of adult shellfish, increasing meat content and improving sensory attributes. In parallel, marine biotechnology has promoted the valorization of biomass, including the production of mineral powders from fish bones and more functional and digestible feeds based on fermented insect meal. In addition, the extraction of antioxidant compounds from algae enables the production of high-value biomolecules and the development of innovative biomaterials, such as leather alternatives.
Together, these technologies reinforce the integration between aquaculture, marine biotechnology, and the circular economy, promoting more sustainable and efficient systems focused on the full valorization of marine resources.
Method for Rearing ShellFish
The invention provides a rearing method for adult shellfish that maintains and increases meat content. The method enhances appearance, taste, and flavor. The process includes preparing an algae solution with a concentration of at least 0.3 × 10⁶ cells/mL. Adult shellfish are then immersed in this algae solution.

Fish Bone Power: Method and Device for Preparing the Same
The disclosure describes a method and device for producing fish bone powder with enhanced nutritional value. The process starts by obtaining an intermediate powder rich in calcium and phosphorus from fish bones. This powder is mixed with a base containing vitamins D3 and B3, followed by two controlled heating stages with agitation. A vinegar solution is then added to trigger a fermentation reaction.
The final product is a nutritionally enriched powder containing calcium, phosphorus, collagen, vitamin B3, and calcitriol

A Fish Feed Production Method using Fermented Flour Moth (Ephestia Kuehnilla) for a Protein Raw Material.
The invention describes a method for producing fish feed using the insect Ephestia Kuehniella as a raw material to improve digestibility and nutritional value.
The process begins with large-scale insect production, followed by drying, cooling, and grinding into a powder. This powder is then enriched with molasses, sterilized, and inoculated with Saccharomyces yeasts for fermentation. Finally, the fermented product is blended with other ingredients to produce a more efficient fish feed for growth and health.

Extraction System and Method of Antioxidant Compounds
The invention describes a process for extracting antioxidant compounds from seaweed biomass using aqueous extraction with small amounts of alcohol under controlled temperature and agitation. The crude extract is then separated and purified through ultrafiltration to obtain a polyphenol-rich fraction.
The extract is dried by freeze-drying or spray drying to produce an antioxidant powder. Additional steps may include sequential extraction of compounds such as fucoxanthin and fucoidan using specialized methods. The process enables full utilization of brown seaweed biomass, generating multiple valuable products for food, agriculture, cosmetic, nutraceutical, and pharmaceutical uses.

Flexible Artificial Leather with Carbon Storage Algae Fillers, Method and Uses Thereof
The invention describes a flexible multilayer synthetic leather-like material for automotive applications incorporating algae particles as bio-fillers in polymer layers such as PVC. It also includes expandable microspheres and textile reinforcements to support structure and performance. Replacing part of the chemical fillers with algae reduces weight and improves environmental sustainability through carbon sequestration. The material maintains key mechanical properties such as tensile strength, tear resistance, and abrasion resistance.
