Zeynali, Mansour Yavari, Vahid Morshedi, Vahid Ghasemi, Ahmad Kochanian, Preeta Karapetyan, Anna Mozanzadeh, Mansour Torfi Animals Larva Microplastics Water Pollutants, Chemical Polyethylene Bass Antioxidants Oxidative Stress A 10-day study was carried out to examine the effects of polyethylene microplastics (PEMP) on growth, antioxidant capacity, stress-related genes transcription, and gut histology of Asian seabass (Lates calcarifer) (Bloch, 1970) larvae. In this regard, 2 day old post hatch larvae were exposed to four concentrations of PEMP, including 1) control (without PEMP addition), 2) PEMP50 (50 μg PEMP/L), 3) PEMP100 (100 μg PEMP/L) and 4) PEMP500 (500 μg PEMP/L). Two days post hatching larvae (mouth opening time) were distributed into twelve 120-L cylindrical polyethylene tanks, each filled with 100 L seawater (47.0 ± 0.5 g/L, 32 ± 0.8 °C) (2500 larvae in each tank, 25 larvae/L). Different dosages of the PEMP were diluted in ethanol, then added to the larviculture tanks and larvae were exposed to each treatment for 10 days. Each treatment was replicated in three tanks. Rotifers (Brachionus plicatilis small type, 5-10 animals/mL) were offered to larvae from second DPH to 10 DPH in a green water (0.1-0.3 × 10 cell/ml Nannochloropsis. sp) system. The highest and lowest survival rate were in control (28.50 ± 3.38 %) and PEMP500 (3.50 ± 0.12 %) groups, respectively (P |
