Predation, habitat use and impact of Pterois

  1. 1. Paul FurumoMayra Sánchez24 Oct. 2012
  2. 2. Research Problem• There is insufficient data on the abundance and distribution of lionfish in mangrove habitat• Mangroves provide nurseries for reef fishes, therefore the effect of invasion into these habitats are of severe concern.• Furthermore, management strategies have largely focused on reefs at the expense of mangrove habitats.
  3. 3. Objective and Goals O 1: Determine the extent of lionfish abundance in mangrove habitats in Puerto Rico. H 1: Lionfish are present in Mangroves in abundance comparable to other invaded habitat. O 2: Characterize and quantify prey composition of mangrove dwelling lionfish. H 2: Lionfish presence is going to be related to the amount of prey available in mangroves. O 3: Determine if lionfish use mangroves as nurseries similar to other reef fishes. H 3: We assume that lionfish demonstrate a similar pattern as other reef fish that use mangroves as nurseries and migrate to reefs. http://absci.fiu.edu/?p=2345
  4. 4. Objective and Goals O 4: Determine the ontogenical behavior cues that cause lionfish recruitment and migration between mangrove and reef habitat. H 4: Lionfish migrate from mangroves towards reef habitat upon attaining sexual maturity O 5: Determine if they have a preference for impacted and non-impacted mangroves. H 5: We assume the less impacted the http://absci.fiu.edu/?p=341 ecosystem there is going to be more abundance of lionfish.
  5. 5. Methodology Study Sites  Bosque estatal Piñoes, Carolina (BP)  Reserva Natural Bahia de Jobos, Salina (BJ)  La Parguera (LP) Characterize and quantify prey composition  Identify stomach content Population dynamics  Abundance- belt transects 20 * 2 m (2) Transects (Mumby et al., 2004)  Total Length  Age determination (Otolith)  Sexual Maturity (Dissection observation)
  6. 6. Potential Benefits Improve our overall knowledge of lionfish use in mangrove habitat. Incorporate findings into more efficient and inclusive management strategies.
