The Sardine run associated with a bloom of the diatom genus Fragilariopsis was observed along the inshore coastal waters off Kanhangad during the last phase of the summer monsoon 2019. There was an unusual shoreward dumping of live oil sardines along with the waves throughout the day. High salinity (33 psu) and nutrient concentrations (Nitrate 16.33 μmol L⁻¹ and silicate 13.9 μmol L⁻¹) favoured the proliferation of Fragilariopsis spp. (7 × 10⁴ cells L⁻¹), in the coastal waters making them a major diet component of the oil sardines.

“沙丁鱼滑坡”​​沿印度西南海岸坎汉格（Kasaragod）沿沿海水域

在2019年夏季风的最后阶段，在坎汉加德（Kanhangad）附近的近海沿岸观察到了与硅藻属Fragilariopsis盛开相关的沙丁鱼活动。全天都有不寻常的向岸倾倒活油沙丁鱼和海浪。高盐度（33 psu）和养分浓度（硝酸盐16.33μmolL ^-1和硅酸盐13.9μmolL ^-1）促进了脆皮菌的繁殖。（7×10 ⁴细胞L ^-1），在沿海水域使其成为沙丁鱼油的主要饮食成分。
