Aquaculture Diets with Charcoal

The invention relates to the field of aquaculture diets and the field of feeding and cultivating aquatic organisms including fish, such as gilthead seabream, crustaceans, and shrimp. A diet for aquaculture in the form of pellets with specific dimensions, a high percentage by weight of protein, and including a charcoal source is described. The results show that aquaculture diets have several advantages over prior art diets.

A study by Portuguese and Spanish researchers advances a technique for extracting high-value lipids from the heads of sea bream and sea bass.

Spanish and Portuguese researchers in the field of nutrition are applying a new technology that rapidly recovers omega-3-rich oils from the discarded heads of high-quality, biotechnology-farmed sea bream and sea bass. Specifically, the study aimed to

The objective was to apply a microwave-assisted extraction liquid recovery technology. This technology has already been used on Atlantic salmon, so another objective of the study was to adapt it to these two species: sea bream and sea bass.

Harmless sterilizing agent using hemocyanin and functionalized fullerenes with broad-spectrum microbiocidal and intracellular and interstitial radical scavenging effects for packaged material, biological and organic products, including liquids, gases, tissues, organs, cells and limbs with copper-mediated oxygenation for viability and preservation.

This invention relates to a compound transplant tissue and organ suspension filled with halogenated and functionalized hemocyanin to enhance the quality, integrity, preservation and sterility of packaged material, storage medium and/or nutrient medium. Hemocyanin can be derived from various species of arthropods and mollusks, such as the horseshoe crab (Limulus polyphemus). The enhancing suspension provides oxygen transport, broad-spectrum antimicrobial and free radical scavenging characteristics to traditional storage and nutrient media, as well as to packaged material, without the use of potentially harmful biocidal agents such as antiseptics, detergents, disinfectants, antibiotics, antifungals, surfactants, germicides, or immunogenic substances that can lead to cytotoxicity when added to transplanted tissue.
