🐟Channel catfish
찬넬동자개(영어: Channel catfish, 학명: Ictalurus punctatus), 또는 찬넬 메기는 메기목 붕메기과에 속하는 잡식성 민물고기다. 원래 미국 걸프 해안, 미시시피 강 유역과 멕시코의 강에 분포했으나 양식종으로 여러 나라에 도입되면서 유럽, 아시아 및 남미에도 서식하고 있다. 몸은 원통형이며 비늘이 없다. 등지느러미와 꼬리지느러미 사이에 기름지느러미를 가지고 있다. 입 주변에 메기목의 특징인 수염을 가지고 있다. 이빨은 거의 없으며 먹이를 통째로 삼킨다. 미국에서 가장 많이 어획되는 메기 종으로 연간 약 800만명의 낚시꾼들이 찬넬동자개를 낚는다. 식용으로도 인기가 많아 찬넬동자개의 양식 산업이 빠르게 발전했다. 다른 여러 나라에도 양식종으로 도입되었으나 법적 침입종으로 규정하고 있는 나라도 많다.
