Researchers evaluated protein hydrolysates from insects and marine invertebrates as replacements for fetal bovine serum in fish cell culture media, working toward more sustainable and cost-effective approaches for cultivated fish production.
Effects of the use of synthetic astaxanthin in the feeding of Lophiosilurus alexandri, a neotropical siluriform fish
Researchers found that feeding synthetic astaxanthin to Lophiosilurus alexandri juveniles at 100 mg/kg inclusion level resulted in optimal carotenoid retention in tissues without significantly affecting growth, blood biochemistry, or liver histology.
Effects of Dietary Vitamin C on the Growth Performance, Biochemical Parameters, and Antioxidant Activity of Coho Salmon Oncorhynchus kisutch (Walbaum, 1792) Postsmolts
Researchers determined that coho salmon postsmolts require a dietary vitamin C concentration of approximately 100 mg/kg for optimal growth performance, antioxidant activity, and serum biochemical health, with higher doses providing diminishing returns.
Effect of Stocking Density on Survival, Growth and Production of Indigenous Labeo Calbasu (hamilton, 1822) in Nursery Ponds
Experiments on nursery rearing of Labeo calbasu fish in Bangladesh found that optimal stocking densities significantly improved survival and growth, providing practical guidance for freshwater aquaculture.
Development and evaluation of a fish feed mixture containing the probiotic Lactiplantibacillus plantarum prepared using an innovative pellet coating method
Researchers developed an innovative pellet coating method for fish feed using the probiotic Lactiplantibacillus plantarum, demonstrating stable probiotic survival during storage and gradual release over 24 hours, along with improved nutrient composition of the feed pellets.
Utilization of Fish Waste Flour as a Substitute for Fish Meal on the Growth Rate and Survival of Catfish (Clarias sp.)
Despite its classification in this database, this study tests fish waste flour as a substitute for fish meal in catfish feed — not microplastic research. A 30% substitution of fish waste flour produced the best growth performance, with a feed conversion ratio of 1.62 and specific growth rate of 3.87% per day.
Efficacy of Black Soldier Fly (Hermetia illucens) Larvae Meal as Feed on Growth Performance for Juvenile Javan Mahseer (Tor tambra)
Black soldier fly larvae meal was tested as a replacement for fishmeal in feed for juvenile Javan Mahseer fish to address the sustainability crisis of fishmeal dependency. Growth performance was evaluated under different substitution levels. This research supports alternatives to overfishing-linked fishmeal while maintaining aquaculture productivity.
Sustainable feed formulation to community‐based aquaculture: Oreochromis niloticus fingerlings performance and antioxidant status
This study developed sustainable fish feed formulations for community-based tilapia aquaculture using locally available plant-based ingredients, addressing a need for feeds that reduce dependence on imported fishmeal. Sustainable aquaculture feed reduces both supply chain vulnerability and the indirect environmental footprint of fish farming.
Supplementation of Enzymatic Hydrolysate in Low-Fishmeal and Low-Crop Diet Improves Growth, Antioxidant Capacity, and Immunity of Juvenile Sea Cucumber Apostichopus japonicus (Selenka)

L-arginine, matters for skin health of leopard coral grouper (Plectropomus leopardus)
Researchers determined that dietary L-arginine at 3.72% of dry matter optimizes growth and skin health in leopard coral grouper, enhancing pigmentation, antioxidant capacity, and immune function over an 8-week feeding trial.
Microplastics contamination in commercial fish meal and feed: a major concern in the cultured organisms
Researchers analyzed commercial fish meal and animal feed samples and found microplastics in all of them, with fish meal containing up to 1,154 particles per kilogram. The contaminated feed is given to farmed fish, shrimp, and chicken, creating a pathway for microplastics to reach humans through the food supply. Feed made from dried fish had higher contamination levels than feed from fresh fish, and the microplastics also carried toxic heavy metals.
