Abstract or Summary
  • Artificial reefs create less productive fish communities than their natural counterparts mostly due to differences in habitat complexity and food potential. Are there other factors contributing to this decrease in productivity, such as the material of the habitat? I tested the response of the tidepool sculpin, Oligocottus maculatus, to man-made and natural shelters to determine if sculpin have an inherit aversion to man-made materials. Tidepool sculpin were collected from one Oregon coast site (Yachats Beach) and acclimated to either a rock or Lego structure, or no structure at all. After an acclimation period, the fish were placed in a tank with both a Lego and a rock structure on opposing sides. I recorded the proportion of time spent on either the Lego or rock side and shelter choice and shelter interaction time. Though none of my results were statistically significant, several patterns were observed. Lego acclimated fish spent more interaction time with the Lego structure and rock acclimated fish spent more interaction time with rock structure. Fish that were acclimated to no structure also favored the rock structure. However, Lego acclimated fish spent more time on the rock side of the tank and rock acclimated fish spent more time on the Lego side. This may be indicative of an exploration behavior. The lack of preference for the rock structure or side of tank implies that tidepool sculpin have no aversion to Legos or other man-made materials.
