Fish-name character

It names a fish. 魚 points to the fish category; 嘗 hints at the Mandarin sound.

The Chinese dictionary 說文解字 records 鱨; the Han-era poem 西京賦 lists it among fish at Kunming Pond. Chinese and Japanese dictionaries keep the fish-name sense but describe different fish, including a yellow-backed fish like a catfish and freshwater fish known by the Japanese names ギギ and ギバチ. 鲿 is its simplified Chinese form; 𩼝 is another recorded variant.
