Global increases in beach sand temperatures are predicted to skew hatchling sexratios of marine turtle populations towards female bias. Currently, shade structures and fresh-water irrigation are management strategies used to cool nest temperatures, but require resources that are limited at remote rookeries. Here, we report on a novel investigation that used seawater irrigation as a sand-cooling method. Various volumes of seawater were applied to sand to deter-mine the optimal application required to lower sand temperatures at nest depth to produce male-biased sex ratios.

Sea grapes (Caulerpa species. Chlorophyta) are widely consumed in the Pacific as a delicacy, a salad and as an addition to many dishes. The traditional harvesting and consumption of sea grapes in the Pacific may well have had their origins among South-East Asian peoples who migrated to and colonized the Pacific Islands 3-4,000 years ago. Sea grapes are consumed throughout the region by Melanesian, Micronesian and Polynesian peoples.

Nile tilapia (oreochromis niloticus) is an introduced low-value freshwater fish in the Pacific which can easily adapt to a wide variety of breeding environments. However, this fresh water fish has limited scope for consumption in the fresh form in Pacific Island countries like Fiji, Samoa and Tonga. Tilapia could be used to alleviate food security issues in light of the increasing fishing pressure and climate change threats
