Abstract

This study aimed to evaluate the potential of basil seed simplicia supplementation in feed to mitigate histomorphometric alterations and muscle damage in African catfish (Clarias gariepinus) exposed to polystyrene (PS) microplastics. The experiment employed a Completely Randomized Design (CRD) consisting of five treatments: C (0 mg/L PS microplastics + 0% basil seed simplicia), PC (0 mg/L PS microplastics + 2% basil seed simplicia), NC (100 mg/L PS microplastics + 0% basil seed simplicia), T1 (100 mg/L PS microplastics + 2% basil seed simplicia), and T2 (100 mg/L PS microplastics + 4% basil seed simplicia). A total of 125 catfish were exposed to microplastics for 15 days. The observed parameters included myofiber diameter, myofiber area, muscle degeneration, and necrosis. The results indicated that exposure to PS microplastics significantly decreased myofiber diameter and area while increasing the levels of muscle cell degeneration and necrosis (P < 0.05). Supplementation with 2% basil seed simplicia (T1) significantly improved myofiber diameter and area and reduced muscle degeneration and necrosis compared with the negative control (NC), whereas supplementation with 4% basil seed simplicia (T2) showed relatively lower effectiveness. These findings suggest that supplementation of 2% basil seed simplicia in feed has the potential to mitigate histomorphometric alterations and muscle tissue damage in catfish exposed to polystyrene microplastics.

Abstract

Polystyrene (PS) microplastics are widely detected in aquatic environments, particularly in freshwater ecosystems, and may pose ecological risks to aquatic organisms. However, information on how PS microplastics affect the giant freshwater prawn, an economically important freshwater aquaculture species, remains limited, particularly at the tissue level. This study therefore investigated the effects of PS microplastics in rearing media on microplastic accumulation, growth performance, and histomorphometry of the giant freshwater prawn. Following a three-day acclimation period, prawns were exposed to four concentrations of PS microplastics (0, 1, 10, and 100 mg/L) for 14 days. Growth parameters (length and weight), microplastic abundance in organs (gills, intestine, and muscle), and histomorphometry of the gills, intestine, and muscle were evaluated using hematoxylin–eosin staining. Data were analyzed using analysis of variance or Kruskal–Wallis tests followed by Duncan’s test and regression analysis. The results showed that microplastic abundance in the rearing media significantly increased microplastic accumulation in the gills and muscle (p < 0.05), but not in the intestine (p > 0.05). Exposure to PS microplastics did not significantly affect growth performance or gill lamella length (p > 0.05). However, significant alterations were observed on intestinal histological parameters and muscle myofiber structure (p < 0.05). These findings demonstrate that PS microplastics can induce tissue-level alterations in M. rosenbergii despite the absence of short-term growth effects.
