Effect of Probiotic Supplimentations on the Gut Histoarchitecture of Stinging Catfish, Heteropneustes fossilis
Summary
This aquaculture study evaluated the effects of probiotic supplementation on gut histology in stinging catfish, finding that probiotics improved intestinal morphology—relevant to understanding how gut health modifications may influence susceptibility to microplastic-induced gastrointestinal damage.
The study was conducted to evaluate the effect of probiotics on the gut histology of stinging catfish, Heteropneustes fossilis. The experiment was conducted in 15 ponds, each with 0.75 decimal and stocking density were 550 fingerlings/decimal (6.44 ± 0.054 gm) and cultured for 90 days (May to August). Commercially available gut probiotic ZYMETIN, water probiotic pH FIXER and soil probiotic Super PS were used in the experiment. T1 was designed with the recommended dose of Super PS (soil probiotic). T2 was supplemented with the recommended dose of gut probiotic (ZYMETIN). T3 was designed with combined application of Super PS, ZYMETIN and pH FIXER at recommended doses. T4 was designed with the recommended dose of water probiotic (pH FIXER). Only basal feed was applied for T5 (control). Water quality parameters, morphometric measurements, body weight of the experimental fish were measured, and fish gut samples were collected for histological study at fortnightly intervals. The results showed that all water quality parameters in pH FIXER treated ponds were more favorable for fish culture compared with others. In combined probiotic treated groups (T3) histoarchitecture of the gut were almost normal. Less pathological signs were observed in probiotic treated groups (T1, T2, and T4) compared with T5 (control). From analysis of gut revealed that fold length, fold width and epithelial layer thickness were increased significantly (P < 0.05) in combined probiotics treated fish. Fish from T2 and T3 exhibited larger fold length, width and epithelial layer thickness than those of T1, T4, T5 (control). Probiotic addition can improve intestinal structure of H. fossilis which may increase the nutrients absorption in fish. Hence, digestion capacity was increased that ultimately helps to improve the overall health condition of stinging catfish, H. fossilis.

Histomorphological Changes in Fish Gut in Response to Prebiotics and Probiotics Treatment to Improve Their Health Status: A Review
This review summarizes how prebiotics and probiotics, beneficial supplements added to fish feed, can improve gut health and disease resistance in farmed fish. A healthy gut microbiome is critical for nutrient absorption and immune defense in fish. While not directly about microplastics, the research is relevant because microplastics are known to disrupt gut bacteria in aquatic organisms, and probiotics may help counteract some of those effects.
The Effects of Probiotics on the Recovery of Growth, Digestive, Antioxidant, Immune Functions, and Gut Microbiota of Chinese Hooksnout Carp (Opsariichthys bidens) Under Microplastic Stress
Researchers exposed juvenile Chinese hooksnout carp to polystyrene microplastics for seven days, then administered Bacillus coagulans probiotics at three doses for 56 days and found that medium and high probiotic doses significantly improved growth, digestive enzyme activity, antioxidant function, and gut microbiota recovery.
Probiotics, Prebiotics, and Synbiotics Utilization in Crayfish Aquaculture and Factors Affecting Gut Microbiota
This review examines how probiotics, prebiotics, and synbiotics can improve gut health and disease resistance in farmed crayfish. These supplements help maintain beneficial gut bacteria, boost immune function, and reduce the need for antibiotics in aquaculture. The research is relevant to microplastic concerns because healthy gut microbiomes in aquatic organisms may be more resilient to disruption from environmental contaminants like microplastics.
Supplementary Feed Potential on Histology and Immune Response of Tilapia (Oreochromis niloticus L.) Exposed to Microplastics
Researchers found that supplementing tilapia feed with probiotics or vitamin C significantly mitigated microplastic-induced organ damage, reducing liver necrosis and inflammation markers while improving intestinal structure and immune cytokine balance.
Effects of microplastic fibers on Lates calcarifer juveniles: Accumulation, oxidative stress, intestine microbiome dysbiosis and histological damage
Researchers fed juvenile barramundi fish polyethylene microplastic fibers for 56 days and found that while the fibers did not affect growth, they induced intestinal oxidative stress and disrupted the gut microbiome. Beneficial bacteria including Lactobacillus species were significantly reduced, while overall microbial diversity declined. The study suggests that microplastic fiber ingestion can compromise intestinal health in marine fish even without observable effects on growth.
