The marine diatoms spp. are globally distributed primary producers, with certain species capable of producing neurotoxin domoic acid (DA), causing amnesic shellfish poisoning (ASP). This study investigates the toxicity and growth rates of species isolated from aquaculture areas in the Central Adriatic Sea. A total of 54 strains from eight species were analysed, with strains originating from four different study sites. Growth rates and toxin production were examined across different growth phases in other species and strains. Most species, including , , , , , , and , did not produce DA at any growth phase. The only species that showed toxin production, at 18 °C was (0.0007-0.0250 pg cell). Notably, the majority of strains were toxic in the decay phase and some strains showed continuous toxin production throughout all growth phases. The highest growth rates for the analysed species were recorded in strains of which also exhibited the highest cell abundance (8.19 × 10 cell mL), followed by the species , and
海洋硅藻属是全球分布的初级生产者，某些物种能够产生神经毒素软骨藻酸（DA），导致失忆性贝类中毒（ASP）。本研究调查了从亚得里亚海中部养殖区分离出的物种的毒性和生长速率。共分析了来自8个物种的54个菌株，这些菌株来自4个不同的研究地点。研究了其他物种和菌株在不同生长阶段的生长速率和毒素产生情况。大多数物种，包括……（此处原文缺失具体物种名称），在任何生长阶段都不产生DA。唯一在18℃时显示出毒素产生的物种是……（此处原文缺失具体物种名称）（0.0007 - 0.0250 pg/细胞）。值得注意的是，大多数……（此处原文缺失具体物种名称）菌株在衰退期有毒，一些菌株在所有生长阶段都持续产生毒素。所分析物种的最高生长速率记录在……（此处原文缺失具体物种名称）菌株中，该菌株也表现出最高的细胞丰度（8.19×10细胞/mL），其次是……（此处原文缺失具体物种名称）物种。
