Reef Monitoring 1

  1. 1. Oceanic Society Belize Field Station Blackbird Caye, Turneffe Atoll Katherine Cure, M.S. , P.I.
  2. 2. <ul><li>We encourage volunteers to review this material prior to arriving at the Field Station. It will aid in preparation for the monitoring event. </li></ul><ul><li>However, it is not a requirement of the program to review or study this material. Slides will be discussed in detail on site by the OS Researcher in charge. </li></ul><ul><li>Training will be offered on a daily basis at the Field Station and researcher will make sure you are up to speed with what is required of you as a volunteer </li></ul><ul><li>If you have any questions, please feel free to contact OS Researcher before arrival or during your stay at Blackbird CONTACT INFO: Katherine Cure, M.Sc. [email_address] , [email_address] </li></ul>
  3. 3. <ul><li>A long term endeavour to assess reef health and provide information to managers </li></ul><ul><li>Monitoring at Oceanic is modelled from programs that are being used in the wider Caribbean Region and in Belize (AGRRA, MBRS) </li></ul><ul><li>However, we focus on some indicators that give the most important information, in order to get data of the best possible quality, with the available resources </li></ul>
  4. 4. <ul><li>Long-term monitoring allows tracking of changes in community structure on the reef over time </li></ul><ul><li>Data can be collected over seasons and years to determine which changes are due to natural variability and which are the result of human pressure </li></ul><ul><li>Baseline ecological data on coral reef health is crucial to management planning </li></ul>
  5. 5. <ul><li>Fish Abundance: </li></ul><ul><ul><li>Consists of an assessment of the number of individuals in one of 6 categories -- Recorded by Volunteers </li></ul></ul><ul><li>Abundance of long spiny sea urchins </li></ul><ul><ul><li>Recorded by Volunteers </li></ul></ul><ul><li>Coral Condition and Disease: </li></ul><ul><ul><li>Recorded by Researcher </li></ul></ul><ul><ul><li>Presence/absence of disease and bleaching </li></ul></ul><ul><ul><li>Condition of corals (i.e. live tissue, % mortality) </li></ul></ul>
  6. 6. <ul><li>FISH ABUNDANCE </li></ul><ul><ul><li>Six categories </li></ul></ul><ul><ul><li>Count number of individuals in each </li></ul></ul><ul><li>SPINY SEA URCHIN ABUNDANCE </li></ul><ul><ul><li>Diadema antillarum </li></ul></ul><ul><ul><li>Count number of individuals </li></ul></ul><ul><li>ENVIRONMENTAL Variables </li></ul>
  7. 7. <ul><li>Reef fish abundance and diversity are excellent indicators of reef health, given the close relationship between fish and the habitat they live and depend on </li></ul><ul><li>It is important to monitor different trophic levels, in order to get an adequate representation of the fish community at all levels of the food chain </li></ul><ul><li>Fish abundance will be recorded for key families including herbivores, carnivores and omnivores </li></ul>
  8. 8. <ul><li>There are six categories of fish to count, but no worries! There is plenty of time to learn them all </li></ul><ul><li>Categories to count (5 families + 1 sp.) : </li></ul><ul><ul><li>Parrotfishes (Flia. Scaridae) </li></ul></ul><ul><ul><li>Surgeonfishes (Flia. Acanthuridae) </li></ul></ul><ul><ul><li>Butterflyfishes (Flia. Chaetodontidae) </li></ul></ul><ul><ul><li>Snappers (Flia. Lutjanidae) </li></ul></ul><ul><ul><li>Groupers (Flia. Serranidae) </li></ul></ul><ul><ul><li>Hogfish (Lachnolaimus maximus) </li></ul></ul>
  9. 9. <ul><li>CHARACTERISTICS: </li></ul><ul><ul><li>Large scales </li></ul></ul><ul><ul><li>Beak-like mouths </li></ul></ul><ul><ul><li>BEHAVIOUR: </li></ul></ul><ul><ul><ul><li>Swim with pectoral fins </li></ul></ul></ul><ul><ul><ul><li>Constantly feeding </li></ul></ul></ul><ul><li>IMPORTANCE: </li></ul><ul><ul><li>Key herbivores </li></ul></ul><ul><li>YOU WILL RECORD AS: </li></ul><ul><ul><li>Adults </li></ul></ul><ul><ul><li>Juveniles </li></ul></ul>
