Coastal Fisheries & Climate Change By Monte Depaune
Introduction Coastal fisheries is the main source of seafood for people on Nauru with an estimated annual catch of 420t of finfish and 231t of invertebrates. Nauruan fresh fish consumption per capita is 56kg. Nearly half the population (4513 people, 2947 males and 1566 females) are engaged in fishing activities.
Nature of Our Coastal Fisheries Recent Catch and Value
Reef fisheries Nearshore pelagic (tuna) fisheries Inter/subtidal shellfish fisheries
Projected Changes to Coastal Fish Habitat (coral reefs) Projected changes to coastal fish habitat 2035 2050 2100
Coral bleaching due to increased temperature Ocean acidification - reef erosion
Projected Changes to Coastal Fisheries Projected changes to coastal fisheries production 2035 2050 2100 Reef fish
Effects of climate change on reef fish Today 2035(-2 to -5%) 2050 (-20%) 2100 (-20 to -50%)
Summary Coral reef fisheries will be ‘losers’ under climate change. Mainly due to changes in their habitat There are severe implications! Adaptations are possible.
