Effects of Yu-Ping-Feng polysaccharides (YPP) on the growth performance, intestinal health and lipid metabolism of largemouth bass (Micropterus salmoides)
Summary
This paper is not about microplastics; it investigates the effects of Yu-Ping-Feng polysaccharides on growth, intestinal health, and lipid metabolism in largemouth bass, with no connection to plastic or microplastic research.
Abstract This study aimed to investigate the effects of Yupingfeng polysaccharides (YPP), polysaccharides compound, on the growth performance, intestinal health, and lipid metabolism of largemouth bass ( Micropterus salmoides ). The attractive effects of YPP on largemouth bass through ball biting test, and further determine the concentration gradient of YPP. Four iso-nitrogenous diets were prepared by mixing and stirring 0%, 2%, 4%, and 8% YPP to commercial feed. A total of 360 fish with an initial weight of 20 ± 0.5 g were randomly assigned to 12 tanks (4 dietary groups × 3 replicates) in a recirculation system and fed twice daily for 4 weeks. The orthogonal polynomial contrasts showed that dietary YPP levels had significant interactions with growth performance, intestinal health and lipid metabolism. Pearson correlation analysis showed that fish growth was closely correlated with intestinal health, liver health, lipid metabolism and brain feeding related gene expression ( P < 0.05). Overall, the results indicated that adding moderate dose of YPP to the diet could promote the growth performance, feeding ability, lipid metabolism ability, and protect intestinal and liver health of largemouth bass.

Effects of Virgin Microplastics on Growth, Intestinal Morphology and Microbiota on Largemouth Bass (Micropterus salmoides)
Researchers found that exposure to virgin microplastics at environmentally relevant concentrations impaired growth, caused intestinal morphological damage, and altered gut microbiota composition in largemouth bass, suggesting that microplastic ingestion poses health risks in commercially important aquaculture species.
Effects of polystyrene nanoplastics on oxidative stress, histopathology and intestinal microbiota in largemouth bass (Micropterus salmoides)
Researchers exposed largemouth bass — a commercially important freshwater fish — to polystyrene nanoplastics (tiny plastic particles 100 nanometers in size) for up to 19 days, finding tissue damage in the gills, liver, and intestines along with elevated markers of cellular stress. While growth was not significantly affected, the fish adjusted their gut microbiome in response, suggesting nanoplastics trigger adaptive but potentially harmful physiological changes.
Investigating Polystyrene Nano-Plastic Effects on Largemouth Bass (Micropterus salmoides) Focusing on mRNA Expression: Endoplasmic Reticulum Stress and Lipid Metabolism Dynamics
Researchers investigated how polystyrene nanoplastics affect the liver of largemouth bass, focusing on endoplasmic reticulum stress and fat metabolism. They found that nanoplastic exposure disrupted normal lipid processing and triggered stress responses in liver cells, altering the expression of genes involved in fat storage and energy regulation. The study suggests that nanoplastic pollution in freshwater environments may impair metabolic health in fish.
Increasing microplastic exposure had minimal effects on fatty acid composition in zooplankton and yellow perch in a large, in-lake mesocosm experiment
Researchers found that increasing microplastic exposure levels had minimal effects on fatty acid composition in an aquatic organism, suggesting that at the tested concentrations, microplastics do not substantially disrupt lipid metabolism.
Connection between the Gut Microbiota of Largemouth Bass (Micropterus salmoides) and Microbiota of the aquaponics system Environment
Researchers investigated the relationship between gut microbiota composition in largemouth bass and the presence of microplastics in their digestive tracts, finding that microplastic-exposed fish showed distinct microbial community profiles. Certain bacterial taxa associated with plastic degradation were enriched in fish with higher microplastic burdens, suggesting gut microbiota adapt to plastic ingestion.
