The waters surrounding Choiseul contain some of the highest diversities of coral and reef fish in the world, with the 2004 Solomon Island Marine Assessment showing that the Solomon Islands are part of the global centre for marine diversity known as the Coral Triangle. Other countries that make up the Coral Triangle are Indonesia, Philippines, parts of Malaysia, East Timor and Papua New Guinea. Since 2004 The Nature Conservancy (TNC), the Lauru Land Conference of Tribal Community (LLCTC) and Choiseul provincial fisheries have assisted five local communities around Choiseul in their efforts to establish Marine Conservation Areas (MCA) on their traditional reefs. The first MCA to be established was the Zinoa MCA. Zinoa is located on the south-west side of Choiseul in the Solomon Islands. The Zinoa MCA was established by traditional leaders in November 2004, covering 150 hectares and consisting of two islands and associated reefs that occur approximately one kilometre offshore from Voza village on the Choiseul mainland. The reefs around Zinoa Islands are representative of this region of the South coast of Choiseul. In early 2005 sea cucumbers, trochus and giant clams around Zinoa Islands were reported by traditional reef owners to be only a tiny fraction of their former abundance and food fish populations were also reported to be in decline.

Flourescein dye was used to trace water movements and to determine flow velocities and volume transports on two Guam fringing reef flats. Wave-driven water crossed most portions of the reef margin in a direction roughly perpendicular to the shoreline. As it moved across the reef flat it gradually changed direction until it was flowing as a longshore current in a deepened moat zone adjacent to the shoreline. After flowing in this longshore current for distances up to 1500 m, the water gradually moved seaward in a more dispersed pattern and exited the reef flat through major cuts in the reef margin. Smaller, more restricted portions of both reef flats had very sluggish water movements with less distinct patterns. Of the total water volume crossing transects which extended perpendicularly from the shoreline, 10-100% flowed in the moat zone within 80 m of the shore. Flow velocities ranged up to 0.6 m sec1. Mean volume transport across entire transects was up to 61.6 m3 sec1. and in the moat zone alone was up to 23.5 m3 sec-1. There was a significant correlation between surf and flow velocity, as well as between surf and volume transport in the moat, at all transects and tidal states tested in one bay; but the correlations were less conclusive in the other bay. Velocity was more strongly correlated with surf than was volume transport in the moat for most of the correlation analyses.
