Not directly relevant to microplastics — this review surveys sustainable alternative feed ingredients for aquaculture, covering plant-based proteins, by-products, and insects as replacements for fishmeal and fish oil.
Analysis of the Possibility of Feed Protein Additive Producing from Fish Scales
Researchers analyzed the chemical composition of bream fish scales, finding high concentrations of proteins and lipids including both saturated and unsaturated fatty acids, and assessed their potential as a protein feed additive for animals and aquaculture. The study establishes bream scales as a viable source of nutrients for feed production, offering a pathway for valorizing fish processing waste.
Cell-cultivated aquatic food products: emerging production systems for seafood
This review examines cell-cultivated seafood, a new approach to producing fish protein by growing fish cells in a lab rather than catching or farming fish. One potential benefit is avoiding the microplastic contamination found in wild and farmed fish, since the production environment can be controlled. As concerns grow about microplastics accumulating in seafood, lab-grown alternatives could offer a way to reduce human exposure to microplastics through diet.
Supplementation of Enzymatic Hydrolysate in Low-Fishmeal and Low-Crop Diet Improves Growth, Antioxidant Capacity, and Immunity of Juvenile Sea Cucumber Apostichopus japonicus (Selenka)
Researchers tested whether enzymatic hydrolysate could replace fishmeal and soybean meal in diets for juvenile sea cucumbers, an important aquaculture species. They found that sea cucumbers fed the hydrolysate-supplemented diet showed improved growth, stronger antioxidant defenses, and enhanced immune function. The study supports using enzymatic hydrolysate as a sustainable feed ingredient that could reduce aquaculture's dependence on conventional protein sources.
Enhancing food safety and cultivated meat production: exploring the impact of microplastics on fish muscle cell proliferation and differentiation
Researchers investigated how microplastic contamination affects fish muscle cells used in cultivated meat production. They found that polystyrene microplastics impaired the ability of fish cells to grow and develop into muscle tissue, even at relatively low concentrations. The findings raise concerns about microplastic interference in both lab-grown seafood production and the safety of sourcing cells from marine organisms already exposed to plastic pollution.
Detection and characterisation of microplastics and microfibres in fishmeal and soybean meal
Researchers examined fishmeal and soybean meal used as aquaculture feed ingredients and detected microplastics and semi-synthetic cellulosic microfibers in fishmeal but not in plant-based soybean meal. The findings suggest that animal-based aquaculture feeds represent a route of microplastic contamination for farmed fish.
Investigating the Impact of Microplastics on Fish Muscle Cell Proliferation and Differentiation: Enhancing Food Safety in Cultivated Meat Production
Researchers exposed Atlantic mackerel muscle cells to polyethylene microspheres at concentrations representative of environmental contamination and found that microplastics significantly impaired cell attachment and proliferation, particularly at 10 µg/mL. The findings matter for the growing cultivated meat industry, which sources cells from marine species already exposed to microplastics, raising food safety questions.
Reprocessing seafood waste: challenge to develop aquatic clean meat from fish cells
Researchers discovered that cells derived from discarded fish fins can naturally change shape into muscle-like and fat-like cells without genetic modification, successfully producing a prototype of lab-grown 'aquatic clean meat' and offering a sustainable, low-waste approach to future seafood production.
Detection of Microplastic Contamination in Commercial Insect Meals
Researchers analyzed commercial insect meal products used in aquaculture feed and found microplastic contamination in all samples tested. Using specialized detection methods, they identified various polymer types including polyethylene, polypropylene, and polyester within the insect-based feed. The findings raise questions about whether insect farming, promoted as a sustainable protein source, may inadvertently introduce microplastics into the aquaculture food chain.
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.
Towards Animal-Free Toxicology: Establishment of Two Larval Brown Trout Cell Lines for Environmental Risk Assessment
Researchers established two larval brown trout cell lines to serve as ethically favourable, cost-effective tools for environmental risk assessment and ecotoxicology testing. The new lines expand model diversity for fish-based toxicology studies and contribute to reducing reliance on live animal experiments in environmental science.
Combined Effects of Yellow Mealworm (Tenebrio molitor) and Saccharomyces cerevisiae on the Growth Performance, Feed Utilization Intestinal Health, and Blood Biomarkers of Nile Tilapia (Oreochromis niloticus) Fed Fish Meal-Free Diets
Researchers tested yellow mealworm meal as a replacement for fishmeal in Nile tilapia diets, finding that adding the probiotic yeast Saccharomyces cerevisiae improved fish growth, gut health, liver condition, and immune function. This suggests insect-based feeds combined with probiotics can sustainably replace traditional fishmeal in aquaculture.
The Importance of Fatty Acid Precision Nutrition: Effects of Dietary Fatty Acid Composition on Growth, Hepatic Metabolite, and Intestinal Microbiota in Marine Teleost Trachinotus ovatus
Researchers fed pomfret juveniles three diets with different fatty acid compositions including fish oil, a custom blend oil, and a fish-soybean oil blend and found that the custom blend oil diet matched fish oil for growth while reducing liver inflammation, oxidative stress markers, and pathogenic gut bacteria, supporting precision lipid nutrition in marine aquaculture.
