French Angelfish Exhibit Cleaning Activity in Bonaire

  1. 1. Brian Reckenbeil Moravian College, PA Bonaire 2008 J u v e n i l e F r e n c h A n g e l f i s h C l e a n i n g B e h a v i o r i n B o n a i r e
  2. 2. Background <ul><li>French Angelfish have been studied as cleaner fish in many parts of the world, ex Brazil (Sazima). </li></ul><ul><li>Cleaning species eat parasites off of clients, which is mutualistic to both species. </li></ul><ul><li>In Wicksten’s 1998 study of cleaner fish in Bonaire, only 1 incidence of French Angel cleaning was reported on 2 individuals. </li></ul><ul><li>According to Deloach, FA’s only act as cleaner fish until they reach a length of 7.6 cm (3 in) </li></ul>Photo by Lola Nygaard
  3. 3. What did I do? <ul><li>Juvenile French Angelfish, Pomacanthus paru , were observed near the waters around the yellow submarine dive shop </li></ul><ul><li>The cleaners I observed ranged from 1cm to 5cm </li></ul><ul><li>I looked to see if P. paru have a significant impact as a cleaner species in Bonaire </li></ul>
  4. 4. <ul><li>Sazima, 1999, showed that in Brazil , Juvenile French Angelfish have a large impact in the reef system as a cleaner </li></ul><ul><li>Wicksten, 1998, reports almost no cleaning activity by French Angels in Bonaire </li></ul><ul><li>I wanted to try to figure out why there is a discrepancy between the two studies </li></ul>Why??
  5. 5. <ul><li>Sites 1,5&6 based at man made objects </li></ul><ul><li>Sites 2,3&4 are natural coral heads </li></ul><ul><li>All locations in lagoon area: no deeper than 3m </li></ul>1 5 3 2 4 Cleaning Station Locations Show Video 6

  12. 12. The Clients <ul><li>Over 9.6 hours of Observation: 1.87 hrs spent cleaning </li></ul><ul><li>24 species cleaned during survey </li></ul><ul><li>4 more species seen cleaned NOT during surveys (Spotted Moray, Bicolor Damsel, Brown Chromis and Permit) </li></ul><ul><li>186 cleaning sessions: 168 individuals </li></ul>Photo by Lola Nygaard
  13. 17. Comparing French Angel to other common cleaners: * Unpublished data from Luisa Velasquez 0.001 0.75 1 * Bluehead Wrasse 0.343 1.25 13 * Gobies 0.658 3.5 6 * Pederson Shrimp 1.87 9.6 24/28 French Angel # Hrs Cleaning # Hrs Observed # Client Species Cleaner Species 1.33 0.15 10.4 27 1.71 20 2.50 19.5 New Species/hr % Time Cleaning
  14. 18. So why did Wicksten NOT see much cleaning behavior by French Angels? <ul><li>Location </li></ul><ul><ul><li>Most abundant population of French Angels I have seen IS at yellow sub, and she was surveying off of South Kralendijk, Calabas Reef </li></ul></ul>

  16. 20. So why did Wicksten Not see much cleaning behavior by French Angels? <ul><li>Location </li></ul><ul><ul><li>Most abundant population of French Angels I have seen IS at yellow sub, and she was surveying off of South Kralendijk, Calabas Reef </li></ul></ul><ul><ul><li>Depth </li></ul></ul><ul><ul><ul><li>All my fish were above 3m </li></ul></ul></ul><ul><ul><ul><li>Wicksten studied from 3m to 18m </li></ul></ul></ul>
  17. 21. Other possible studies to consider <ul><li>Relate time spent cleaning to time spent foraging </li></ul><ul><li>Analyze stomach contents </li></ul><ul><ul><li>These could show how much the cleaner depends on cleaning for its food source. </li></ul></ul>
  18. 22. In Conclusion <ul><li>It appears that Juvenile French Angels have an impact as cleaners, at least in the vicinity of the Yellow Sub pier in Bonaire </li></ul><ul><ul><li>Due to </li></ul></ul><ul><ul><ul><li>Time spent cleaning </li></ul></ul></ul><ul><ul><ul><li># Species Cleaned </li></ul></ul></ul><ul><ul><ul><ul><li>Compared to other common cleaners </li></ul></ul></ul></ul><ul><li>They do not however, seem to be a large part of the cleaning on the Reef, since they are found only in shallow waters and not very common elsewhere around the island </li></ul>
