Hamilton, Richard

1. Sea turtles are harvested in many small-scale fisheries (SSFs), but few nations have quantified the impacts that SSFs are having on their sea turtle stocks. This study provides the first assessment on the catch composition, national harvest rates,and long-term trends in sea turtle catches in the Solomon Islands SSFs. 2. Between October 2016 and May 2018, 10 community monitors located in eight of the nine provinces of the Solomon Islands were trained and employed to work alongside fishers in their respective communities to document, photograph, and geo-reference the reefs where sea turtles were harvested. Local ecological knowledge (LEK) surveys were then conducted with 32 experienced fishers to infer whether the harvest rates of sea turtles had changed in recent decades. 3. Community monitors recorded information on 1,132 sea turtles that were harvested on 529 fishing trips:1,119 sea turtles were identified to species level, with harvests consisting of 73.3% (n=818) green sea turtles (Chelonia mydas), 25.7% hawksbill sea turtles (n=291) (Eretmochelys imbricata), and 0.9% (n=10) olive ridley sea turtles (Lepidochelys olivacea). 4. The great majority (92.6%) of sea turtles were captured by night-time and daytime freedivers who use masks, snorkels, fins, hooks, spears, and underwater flashlights to target a wide range of fauna that inhabit coral reefs.

Comprehensive Desk-top Review of Biodiversity, Conservation and Invasive Species Information for the Kingdom of Tonga

Situated between Fiji to the west and Samoa to the northeast, the Kingdom of Tonga (referred to as Tonga) is comprised of 171 scattered islands of which less than 50 are inhabited. The islands are mainly composed of limestone formed from uplifted coral. Current critical environmental concerns have arisen due to deforestation; damage to coral reefs and the introduction and spread of invasive alien species. Anthropogenic pressure has resulted in extensive modification of all ecosystems on the limestone islands of this group. Only uninhabited and steep volcanic islands still support large tracts of forest.
