Obtención y caracterización de colágeno del pez de agua dulce Prochilodus magdalenae: aplicación en películas biodegradables
Researchers extracted collagen from the skin, scales, fins, and heads of a South American freshwater fish and used it to make biodegradable films. The collagen-based films showed promising mechanical and barrier properties for food packaging applications. Using fish processing waste as a raw material for biodegradable packaging could help reduce reliance on conventional single-use plastics.
Microplastics in fish and fishmeal: an emerging environmental challenge?
Researchers found that commercial fishmeal, which is used in animal and fish feed, contains about 124 microplastic particles per kilogram, potentially more than the original fish it was made from. This suggests that the manufacturing process may add extra microplastics to the final product. Through marine aquaculture alone, over 300 million microplastic particles could be released into the ocean annually via fishmeal, creating a cycle where microplastics contaminate both farmed and wild seafood that people eat.
Mollusk shells as marine bioactive materials: Composition, bioactivities, and prospects for food and health applications
Researchers reviewed the bioactive properties of marine mollusk shells, which are generated in large quantities as seafood processing waste. They found that shell-derived compounds exhibit antioxidant, anti-inflammatory, antimicrobial, and bone-building properties, supporting potential uses as natural calcium sources and functional food ingredients. The study highlights an opportunity to turn an abundant waste material into valuable health and food science applications.
Reassessment of dietary protein and lipid requirements for large yellow croaker, Larimichthys crocea, reared in net pens

Environmental Footprint of Inland Fisheries: Integrating LCA Analysis to Assess the Potential of Wastewater-Based Microalga Cultivation as a Promising Solution for Animal Feed Production
Researchers evaluated the environmental impacts of producing microalga biomass for animal feed using inland fisheries wastewater as a culture medium. The study found that using wastewater substantially reduced environmental impacts compared to freshwater-based cultivation, with the scenario combining live algal feed and recycled nutrients emerging as the most promising approach.
Circular bio‐economy in aquaculture
This review examined circular bio-economy approaches in aquaculture, exploring how waste streams can be converted into valuable inputs to reduce the environmental footprint of food production while maintaining productivity and sustainability.
Assessing the effectiveness of microplastic extraction methods on fishmeal with different properties
Researchers evaluated microplastic extraction methods across five fishmeal types varying in protein, organic, carbonate, and density composition, finding that a calcium chloride overflow with dispersant and potassium hydroxide digestion achieved the highest recovery rate (66.3% in sardine and anchovy meal) and concluding that previously reported microplastic concentrations in fishmeal are likely underestimated due to inadequate methodology.
Microplastics in fishmeal: A threatening issue for sustainable aquaculture and human health
Researchers reviewed how microplastics enter aquaculture systems through contaminated fishmeal — made from wild-caught fish that have ingested ocean plastics — and accumulate in farmed fish that are then eaten by humans. The review calls for improved microplastic screening during fish feed production to protect both aquaculture sustainability and public health.
Expanded utilisation of microalgae in global aquafeeds
This review explores how microalgae can be used more widely in aquaculture feeds as a sustainable replacement for fish meal and fish oil. Microalgae provide essential fatty acids, proteins, vitamins, and antioxidant pigments that support fish health and growth. While not directly about microplastics, expanding microalgae-based aquaculture feeds could reduce reliance on wild-caught fish from potentially microplastic-contaminated oceans.
