who is the xaréu-azulado
A fish of the family Emmelichthyidae, the rubyfishes, with a spindle-shaped body. It reaches 34.2 cm standard length. It lives near the bottom, in deep waters of the southeastern Pacific, and has been recorded in Chile, including the Juan Fernández Islands, the only country in Latin America with a record. It is a deep-bottom fish, so it hardly ever turns up for anglers fishing shallow coastal waters. It is commercially fished and poses no danger to anglers.
Essential profile. Identification, where it occurs and rules, with data from FishBase and the cited regulations. Season, time of day, technique and bait are added once we have a good source for the xaréu-azulado.
identification
A fish with a spindle-shaped, slender body, of the rubyfish family (Emmelichthyidae), which usually have a small mouth and a forked tail. It lives near the bottom, in deep waters of Chile, including the Juan Fernández Islands. Location and depth are the main signs: it is not expected in shallow coastal waters, and that sets it apart from jacks and other coastal fish.
