SMART drumlines: calibrated catch data refine non-lethal shark mitigation
Three years of SMART drumline data along the New South Wales coast reveal something essential: non-lethal shark mitigation works, but its effectiveness depends on environmental context. Target species, White, Tiger, and Bull sharks, showed a combined catch rate of 0.66 per 1,000 hook-hours, while bycatch was nearly double that. White sharks preferred colder winter waters; Tiger and Bull sharks were more abundant in warm, calm conditions. This calibrated, empirical catch data allows managers to refine deployment timing and location.
Somalia's Coastal Turtle Exploitation: Drivers, Practices, and Local Perspectives
Along Somalia's Mogadishu and Adale coasts, marine turtle extraction is not accidental bycatch but a targeted, commercialised practice. New empirical data from 25 artisanal fishermen reveals intact Green and Loggerhead turtles commanding up to 120 USD, driven by ethnobiological beliefs in unverified medicinal uses. This demand exposes consumers to chelonitoxism and heavy metal risks. With local enforcement functionally absent, top-down prohibition alone will fail. Co-management and public health messaging offer a more viable path.
Data-Driven Ocean Stewardship: Balancing Fisheries, Aquaculture, and Future Resources.
The science of ocean stewardship is only as strong as the data beneath it. Marine fisheries, aquaculture, and living resources demand frank, unbiased evidence to navigate climate adaptation, shifting species, and food security pressures. Artificial reefs and sustainable feed systems offer measurable pathways forward, yet fragmented governance and regulatory uncertainty remain stubborn barriers. We need integrated, peer-reviewed approaches to translate complexity into actionable policy. As we explore the next decade, the work must be transparent and reproducible.
