The northern snakehead is also called 雷魚 and is popular as a game fish.
The kanji 雷 (thunder) and 魚 (fish) may refer to the snakehead's aggressive behavior or appearance, but the exact origin is uncertain. The reading らいぎょ is the on'yomi of the kanji. The katakana forms ライヒー and ライヒイ likely derive from a Chinese dialectal pronunciation.
