AQUACULTURE
Probiotics and Phytobiotics as Dietary and Water Supplements in Biofloc Aquaculture Systems
Biofloc Technology (BFT) is a sustainable aquaculture system that integrates probiotics and phytobiotics as dietary and water supplements. Probiotics improve water quality and strengthen animal defenses, while phytobiotics, plant-based additives, promote the health and growth of animals. Their proper use can boost farm yields and ensure healthier, more resilient aquatic species, despite challenges in microbial management.

Canadian partnership to transform fish waste into insect meal
NRGene Canada and ILE-A-LA-Crosse are developing and implementing an innovative larval growth technology to convert fish processing waste into high-value resources. This process will enable the production of high-quality protein for the pet food and aquaculture industries, as well as nutrient-rich fertilizers. To achieve this, the technology will optimize Black Soldier Fly (BSF) strains for fish processing waste, maximizing resource efficiency and generating sustainable, high-value-added products.

System for detaching, inactivating, or removing ectoparasites from fish
A system for removing and treating ectoparasites from fish, comprising an inlet for fish and water, a first draining unit to separate fish and water, and a tank containing an aqueous solution with a pH of at least 10.5. A second draining unit separates the fish from the solution. An effective system aimed at monitoring and adjusting the pH of the solution.

LIVING MARINE RESOURCES
Extrudable biodegradable composition materials and extrusion process thereof
An extrudable biodegradable composition includes seaweed nanocellulose in the range of 1 to 3 wt %; a seaweed derivative in the range of 40-99 wt %; biodegradable polymer in the range of 0-30 wt %; plasticizer in the range of 0-25 wt %; and crosslinking agent in the range of 0-15 wt %. The extrudable biodegradable composition has a viscosity greater than approximately 500 cP and an extruded product made from the extrudable biodegradable composition has a controlled water-soluble or water-resistant property with a tensile strength of approximately 10 to 30 MPa.

Seaweed-Derived Bioactive Compounds: Potent Modulators in Breast Cancer Therapy
Breast cancer remains a global challenge, prompting interest in natural therapies like seaweed, which are rich in bioactive compounds such as polysaccharides, polyphenols, and carotenoids. These compounds exhibit antioxidant, anti-inflammatory, and immunomodulatory effects, modulating processes like apoptosis, angiogenesis, and inflammation. Key components like fucoidans and phlorotannins show antiproliferative and antimetastatic properties. This review explores their antitumor mechanisms and potential for integration into breast cancer treatments, highlighting clinical challenges and future research directions.

MARINE BIOTECHNOLOGY
Lichenase and Cellobiohydrolase Activities of a Novel Bi-Functional β-Glucanase from the Marine Bacterium Streptomyces sp. J103
This study characterizes Spg103, a bifunctional β-glucanase from the marine bacterium Streptomyces sp. J103. Spg103, active at 60 °C and pH 6, showed enhanced stability with Na+ and EDTA. The Spg103 exhibits both lichenase and cellobiohydrolase activities, favoring mixed β-glucans, such as barley β-glucan, over β-1,4-linkages. TLC and UPLC-MS analyses confirmed its endolytic activity, producing cellotriose, along with exo-type activity releasing cellobiose. These results suggest that Spg103 holds great potential for biotechnological applications, particularly in the degradation of mixed-linkage β-glucans.

Eco-Friendly Marine-Sourced Materials for Bone and Cartilage Regeneration
Recent advances in bone tissue engineering highlight marine waste byproducts as sustainable resources rich in hydroxyapatite, collagen, calcium carbonate, and essential minerals. Repurposing these materials addresses environmental issues and offers innovative solutions for regenerative medicine. The compatibility of these resources with biological materials such as platelet-rich plasma (PRP), stem cells, as well as nanoparticles (NPs) and polymers, is also emphasized, emphasizing their role in advancing eco-friendly biomedical research.
