| dc.description.abstract | To investigate site fidelity and homing behavior in the intertidal Stichaeidae, Xiphister atropurpureus, mark and recapture studies were conducted at South Cove, Cape Arago Park, in Oregon from July to August 2012. A total of35X atropurpureus were captured, tagged, released, then repeatedly surveyed by conducting numerous census days over a period of 46 days. Out of this total, 15 fish were tagged and released at their home sites and 20 fish were tagged and displaced at varying distances from their home sites (10, 30, 50, or 150m). Of the 15 fish rereleased at their home sites, a total of 5 were recaptured at or within 1.5 m of their home site. The recapture rates ( 13% for home site; 20% for neighboring site) for fish tagged and released at their point of capture indicate that site fidelity is highly likely in this particular species. Of the 20 fish displaced from their home site, only 1 fish from the 30m-displacment group was recaptured. Recapture rates (0% for home site; 20% for neighboring site) for homing behavior indicate that it remains a possibility but requires further studies to determine if it is exhibited in this species. A simple population size estimate was carried out using a Lincoln-Peterson estimate with a Bailey’s adjustment, providing an estimate of approximately 0.77 to 1.47 fish per 100 m2. Site fidelity and homing behavior may be influenced by competitive or territorial behavior and a dispersed population could allow for resource availability. | en_US |
