SUSTAINABLE FISHERIES IN SOUTH PACIFIC: ISSUES & FUTURE DIRECTIONS
Image: ocean color (Seawifs satellite, showing Chlorophyl (phytoplankton), ocean productivity and fisheries potential
SOUTH PACIFIC CORAL REEFS (RED)
OFFSHORE HABITATS: seafloor (very deep) and ocean body
Tuna landings, normal years above,
ENSO yrs (below)
Increased pressures in urban islands
Competition subsistence and commercial
GLOBALLY: fisheries catches declining
70% of stocks overfished/declining
Many stocks collapsed (historic major fisheries cod, some tunas)
World fisheries in crisis
Fisheries management generally declared a failure
Yield (Wt $)
FISHING EFFORT (NO BOATS ETC)
Note: Fish are difficult to study, little biological data, knowledge of populations (fish live in foreign environment, out of sight, fish swim, some migrate vast distances)
Sustainable yield estimates: regulate amount taken each year to be under the estimated maximum yield.
Controls on fishing: Protect undersized fish Limit fishing effort through licensing; control time, seasons, gears etc (ie reducing fishing efficiency, increasing costs)
Previous fisheries management largely unsuccessful. Why?
Ecosystem-based management techniques
The Red Emperor spends different stages of its life cycle utilising different habitats
The life cycle of the red snapper (Lutjanus sebae)
Includes many habitats. All must be protected.
