Abstract
Three species of Carangidae family were caught incidentally during collection of cannonball jellyfish (Stomolophus meleagris) in Bahía de La Paz, Gulf of California, Mexico. All fish were measured, preserved and identified as post flexion larvae and early juvenile of Chloroscombrus orqueta, Hemicaranx leucurus and Caranx caballus. C. orqueta stood out in frequency and abundance. H. leucurus were found only in autumn, while the others were present in different seasons. This is the first time recording H. leucurus and C. caballus associating with cannonball jellyfish. Further studies must evaluate this association as all fish caught were at vulnerable stages, and must be considered in jellyfish fishery management.

By-catch is one of the most significant issues affecting fisheries management today
These kind of association has been reported between different species of jellyfish and various kind of organisms like zooxanthellae, cestodes, trematodes, amphipods, barnacles, cephalopods, fishes and others (Arai 1997), where at least 55 fish species have associated with 27 jellyfish species (Mansueti 1963)
This note reports three carangids fish species, at larvae and juvenile stages, swimming in association to S. meleagris jellyfish when incidentally caught during 2008-2011 surveys; two of this species are reported for the first time
Summary
By-catch is one of the most significant issues affecting fisheries management today. It can disturb the ecosystem, affect biodiversity, create a conservation problem and have economic implications (Alverson et al 1994, Hall et al 2000). By-catch happens when different species (target and non-target catch) are present in the same area and season, but it could happen that these species have an association; so it is common to catch them together. These kind of association has been reported between different species of jellyfish and various kind of organisms like zooxanthellae, cestodes, trematodes, amphipods, barnacles, cephalopods, fishes and others (Arai 1997), where at least 55 fish species have associated with 27 jellyfish species (Mansueti 1963). This note reports three carangids fish species, at larvae and juvenile stages, swimming in association to S. meleagris jellyfish when incidentally caught during 2008-2011 surveys; two of this species are reported for the first time
