Inshore fish populations are complex, exist in variable
and rapidly changing ecosystems, and are harvested
and impacted by a broad range of users, making their
management complex.

Fishing is a complex topic with many species and ecosystem components as well as social, cultural, political, and economic components. Here, we focus on the defined indicator regarding tuna, considering the biomass of these pelagic fish as well as the ecosystems that support these fish. For information about coastal and nearshore fisheries, please see Regional Indicator: Coastal fish biomass.

Simplifying coral reef ecosystems to a single number for a country, or for a region, runs counter to our knowledge of the complexity and variability that characterise healthy reefs in a healthy ocean scape.
Pacific data are limited, but existing data show high
proportions of plastic in the waste stream (Table 29.1),
as marine litter, and as microplastics present throughout Pacific marine ecosystems, including in the guts of fish and their prey (SPREP 2016, Markic et al. 2018). In a 2011 study, plastics formed 12% of the waste stream in Honiara (SPREP 2017).

Enterococci are used as an indicator for the microbiological quality of marine waters from the standpoint of human health. The same bacterial group is also commonly used as an indicator for safe consumption of shellfish. The safety thresholds differ by the type of use, such as swimming or consumption of seafood from the marine area.

Island biodiversity continues to be extremely vulnerable, and 47% of the known threatened Pacific species are declining towards extinction. Pacific island species have high levels of endemism combined with small land areas and therefore limited habitat. Habitat change, naiveté to predation by introduced animals, vulnerability to invasive species-driven changes, pollution, and climate change combine to influence
the abundance and population structure of Pacific biodiversity.

The Pacific island region has diverse wetlands, such as
the classic coastal ecosystems of mangrove forests, salt marshes, coral reefs, and seagrass beds along with rivers, freshwater lakes, and swamps (SPREP 2016). However, these wetlands are understudied. Land-use change and environmental change can alter the areal extent and condition of wetlands, and the pace of these changes vary among Pacific islands.

To date, there is no defined list of priority migratory species of concern (indicator species) at the regional level for the Pacific islands to direct efforts. The Regional Marine Species Action Plans (under revision; see below) and the regional CMS Memorandum of Understanding (2006) for cetaceans can be considered as part of regional level prioritisation. For birds, Bird Life’s Data zone includes a list of migratory species for each country in the region.
