Fish are a major component of the coral reef ecosystem, potentially numbering 500 - 1,100species in Pacific Islands Network (PACN) parks depending on geographic location (Allen et al.2003, Randall 2005, Randall 2007). This highly diverse assemblage of carnivores, planktivores,herbivores and detritivores serve a variety of ecological functions that affect ecosystem structure,productivity, and sustainability (e.g., Sale 1991, Hixon 1997). Fish assemblages or selectedspecies can also act...
More DescriptionFish are a major component of the coral reef ecosystem, potentially numbering 500 - 1,100species in Pacific Islands Network (PACN) parks depending on geographic location (Allen et al.2003, Randall 2005, Randall 2007). This highly diverse assemblage of carnivores, planktivores,herbivores and detritivores serve a variety of ecological functions that affect ecosystem structure,productivity, and sustainability (e.g., Sale 1991, Hixon 1997). Fish assemblages or selectedspecies can also act as indicators of general reef health and provide a warning of environmentalstress and potential ecosystem change (e.g., Friedlander and DeMartini 2002). Additionally, fishwithin the parks are harvested in traditional, subsistence, artisanal, and recreational fisheries(e.g., Craig et al. 2008) which may affect the species composition, abundance and size oftargeted species. Fishing is increasingly being recognized as the principal threat to Pacific coralreefs and other marine ecosystems worldwide (e.g., Dayton 1998, Friedlander and DeMartini2002, Birkeland 2004, Hutchings and Reynolds 2004). In this respect, it is highly probable thatmost of the Pacific Islands parks can be categorized as "impaired" to "seriously impaired" interms of their fish communities. Marine Fish ranked 11th in priority as a network Vital Sign.While the harvest of fish is addressed in a separate complementary (fisheries-dependent)protocol, data collected through the Marine Fish Protocol will contribute to the overallunderstanding by providing an in-water (fisheries-independent) assessment of the size andnumerical density of daytime, non-cryptic species within park waters. Monitoring efforts will beconducted concurrently with Water Quality and Benthic Marine Community Vital Signs tomaximize data interpretation value.
