Blooms of the toxic dinoflagellate could threaten the survival of marine life, and modified clay (MC) is considered a promising method for the control of harmful algal blooms. Here, using marine medaka as the model organism, the toxicity of before and after MC disposal was investigated. The results showed that only a certain density of intact cells could cause obvious damage to fish gills and lead to rapid death. A systematic analysis of morphology, physiology, and molecular biology parameters revealed that the fish gills exhibited structural damage, oxidative damage, osmotic regulation impairment, immune response activation, and signal transduction enhancement. MC can flocculate rapidly in water and reduce its toxicity by reducing the density of intact algae cells and hemolytic toxicity. The results indicate that MC is an effective and safe method for controlling blooms.
有毒甲藻的大量繁殖可能威胁海洋生物的生存,而改性粘土(MC)被认为是控制有害藻华的一种有前景的方法。在此,以海洋青鳉作为模式生物,研究了MC处理前后[甲藻名称未给出]的毒性。结果表明,只有一定密度的完整[甲藻名称未给出]细胞会对鱼鳃造成明显损伤并导致快速死亡。对形态学、生理学和分子生物学参数的系统分析表明,鱼鳃表现出结构损伤、氧化损伤、渗透调节受损、免疫反应激活和信号转导增强。MC能在水中迅速絮凝[甲藻名称未给出],并通过降低完整藻细胞的密度和溶血毒性来降低其毒性。结果表明,MC是控制[甲藻名称未给出]藻华的一种有效且安全的方法。
