To determine the baseline threat of microplastics and polycyclic aromatic hydrocarbons (PAHs) in an important seafood fish from Vueti Navakavu locally managed marine area, a multi-biomarker risk assessment was conducted on the thumbprint emperor fish Lethrinus harak...In this multi-biomarker approach, the observation of pollutants presence and histopathological injuries are considered biologically relevant from a toxicological perspective and serve as a baseline for future pollution studies in seafood fishes in Fiji, with site differences and the inclusion of fish species compariso

Ocean warming is causing declines of coral reefs globally, raising critical questions about the potential for corals to adapt. In the central equatorial Pacific, reefs persisting through recurrent El Niño heatwaves hold important clues. Using an 18-year record of coral cover spanning three major bleaching events, we show that the impact of thermal stress on coral mortality within the Phoenix Island Protected Area (PIPA) has lessened over time.

Climate-driven redistribution of tuna threatens to disrupt the economies of Pacific Small Island Developing States (SIDS) and sustainable management of the world’s largest tuna fishery. Here we show that by 2050, under a high greenhouse gas emissions scenario (RCP 8.5), the total biomass of three tuna species in the waters of ten Pacific SIDS could decline by an average of 13% (range =−5% to −20%) due to a greater proportion of fish occurring in the high seas.

Many species of sharks are threatened with extinction, and there has been a longstanding debate in scientifc and environmental circles over the most efective and appropriate strategy to conserve and protect them. Should we allow for sustainable fsheries exploitation of species which can withstand fshing pressure, or ban all fsheries for sharks and trade in shark products? In the developing world, exploitation of fsheries resources can be essential to food security and poverty alleviation, and global management eforts are typically focused on sustainably maximizing economic benefts.

Substantial efforts and investments are being made to increase the scale and improve the effectiveness of marine conservation globally. Though it is mandated by international law and central to conservation policy, less attention has been given to how to operationalize social equity in and through the pursuit of marine conservation. In this article, we aim to bring greater attention to this topic through reviewing how social equity can be better integrated in marine conservation policy and practice.

Fijians have been at the forefront of ocean action and leadership because it i our responsibility as an oceanic people. Fiji is a nation of over 300 islands whose past, present and future are intrinsically linked to the ocean. The wealth and resources associated with Fiji's vast marine areas represent significant natural capital and are valid pillars of the country's food security. The ocean is also central to traditions, culture, its art, research and education.

Formal and semi-formal networks are emerging as effective, collaborative, and adaptable approaches for addressing complex, rapidly evolving ocean governance issues. One such group of networks, which we refer to as marine-related learning networks, play multifaceted roles within ocean governance systems by facilitating knowledge creation, exchange, and dissemination, and by building the capacity of individuals and institutions to address problems and improve coastal and ocean governance.

Over the last decades scientists have discovered that seagrass meadows, tidal marshes, and mangroves – “blue carbon” ecosystems – are among the most intensive carbon sinks in the biosphere. By sequestering and storing significant amounts of carbon from the atmosphere and ocean, blue carbon ecosystems help mitigate climate change. But conversion and degradation of these ecosystems can also release billions of tons of CO2  and other greenhouse gases into the ocean and atmosphere and contribute to global warming.

Monitoring of marine protected areas (MPAs) is critical for marine ecosystem management, yet current protocols rely on SCUBA-based visual surveys that are costly and time consuming, limiting their scope and effectiveness. Environmental DNA (eDNA) metabarcoding is a promising alternative for marine ecosystem monitoring, but more direct comparisons to visual surveys are needed to understand the strengths and limitations of each approach.

Vava’u, Kingdom of Tonga, is a well-established whale-watching destination in the South Pacific. Between July and October, the waters around the archipelago represent one of the most important breeding grounds for Oceania humpback whales (Megaptera novaeangliae). The Tongan government allows tourist swimming activities with whales and tour operators strongly promote the practice of swimming-with-whales, focusing primarily on mother-calf pairs.
