The channel is named after José de Moraleda y Montero, a Spanish navy officer who explored the area in the 1780s.[1]
The deepest part of the channel are situated in west of Magdalena Island.[2]
In 1985 the discovery of merluzafishing grounds in Moraleda Channel sparkled a fishing boom (boom merluzero) that led to the spontaneous growth of two new settlements; Puerto Gaviota and Puerto Gala.[3]
