rubrivinctus), 27 vermilion rockfish and one lingcod.
Lingcod moved to either Anacapa Island or Platform Gail (Fig.
Despite these potential physical barriers, lingcod, vermilion rockfish and one brown rockfish successfully homed back to their platforms of capture, but also exhibited movement around, away from and between platforms after homing events.
Tagged rockfishes and lingcod removed from offshore oil platforms and translocated to natural habitat at Anacapa Island exhibited the ability to home across previously unrecorded distances and in a relatively short time periods to their platforms of capture.
2009) observed a similar rate of emigration after releasing tagged rockfishes and lingcod at their platforms of capture.
Notably, the homing distances observed in this study are the farthest reported for lingcod, vermilion and brown rockfishes.
Compared to previous experiments displacing rockfishes, results from the current study revealed not only how quickly lingcod and rockfish can recover from catch, release, and tagging stress, but also the speed at which they orient themselves to a new environment and navigate home.
It is not clear why lingcod and vermilion rockfish make such large migrations between platforms and natural habitat.
Variation in temporal and spatial patterns of homing, movements and area use within and among species in this study illustrates behavioral plasticity present in adult rockfish and lingcod populations around offshore oil platforms; this, among other factors, may reduce competition and contribute to population stabilization.
Based on the longer-term patterns in detection after release, rockfishes and lingcod could indeed, be successfully translocated.
