    Coral reefs and small pelagic fisheries: Livelihood and governance interactions in Southern Luzon, Philippines
    Novilla, Carmela Therese T.; Fabinyi, Michael (Springer, 2025-04-02)
    Coral reef fisheries and small pelagic fisheries make different contributions to livelihoods, food and nutrition security, which have informed academic and policy debate about their respective needs for governance. However, few studies have explicitly examined how governance of these different fisheries interacts at a local level, or how they interact with wider social-economic contexts and processes. This study examines a small pelagic fishery in the Philippines, focusing on the varied interactions between this fishery and coral reefs. Drawing on household surveys, focus group discussions and interviews, we demonstrate the significant economic and social contributions made by the small pelagic fishery and describe a series of governance interventions aimed at protecting coral reefs and regulating small pelagics. We highlight some of the emerging governance risks that undermine legitimacy and social acceptance for the management of both small pelagic and coral reef resources. We argue that planning for successful management of fisheries needs to be highly cognizant of the complexity of livelihoods, to equity issues in sharing the benefits and burdens of conservation, and to tourism-fishery interactions.

    Comparative biochemical characterization of pufferfish saxitoxin and tetrodotoxin-binding protein (PSTBP) homologs in the plasma from four Takifugu species: Conservation of heat-stable PSTBP orthologs having three and two tandemly repeated lipocalin domains in genus Takifugu

    To study the relationship between domain characteristics of pufferfish saxitoxin and tetrodotoxin binding protein (PSTBP) proteoforms and their thermal stability, a comparative biochemical characterization of PSTBPs from the plasma of four Takifugu species (T. flavipterus, T. pardalis, T. alboplumbeus and T. rubripes) was conducted by Western blot analysis. The heat-tolerance tetrodotoxin (TTX)-binding ability of PSTBP proteoforms in T. rubripes plasma was verified by ultrafiltration and liquid chromatography tandem mass spectrometry (LC-MS/MS). These results suggest that the heat-stable PSTBP proteoforms, composed of three and two tandemly repeated lipocalin domains, are genetically conserved and ubiquitous in the genus Takifugu. This study builds on our knowledge of the structural and functional properties of PSTBP proteoforms, which is vital for understanding how toxins are transmitted and accumulate in organisms and is essential for evaluating the potential risks of toxins in seafood.
