Ecological data for Myxine circifrons Garman, 1899 (Myxiniformes: Myxinidae) in the gulf of California, Mexico

Resumen

Specimens of the hagfish Myxine circifrons Garman, 1899, were captured in traps in three sampling stations in the southern gulf of California, Mexico. There was no clear relation between oxygen concentration and hagfish abundance. This species appears to be tolerant of moderate (0.28-0.6 ml/l) hypoxia. Other species collected in the traps include Pandalus amplus (Bate, 1888) and Heterocarpus affinis Faxon, 1893, two relatively large species of Pandalidae, and Lebbeus scrippsi Wicksten and Méndez, 1982, a small-size Hippolytidae shrimp. Capture of pandalids was low when hagfish were abundant, thus indicating that competition between the fish and shrimps might prevent the latter to enter the trap.
