Most spatial marine management techniques (e.g., protected areas) draw stationary boundaries around often mobile features, animals, or resource users. While these approaches can work for relatively resources, to be most effective must as fluid in space and time the resources users we aim manage. Instead, a shift towards dynamic ocean is suggested, defined that rapidly changes response its through integration of near real-time biological, oceanographic, social and/or economic data. Dynamic...
Seafood is an essential source of protein for more than 3 billion people worldwide, yet bycatch threatened species in capture fisheries remains a major impediment to sustainability. Management measures designed reduce often result significant economic losses and even closures. Static spatial management approaches can also be rendered ineffective by environmental variability climate change, as productive habitats shift introduce new interactions between human activities protected species. We...
Dynamic ocean management, or management that uses near real-time data to guide the spatial distribution of commercial activities, is an emerging approach balance resource use and conservation. Employing a wide range types, dynamic can be used meet multiple objectives—for example, managing target quota, bycatch reduction, reducing interactions with species conservation concern. Here, we present several prominent examples highlight utility, achievements, challenges, potential this approach....
Abstract Inaccurate or incomplete diagnosis of the root causes overfishing can lead to misguided and ineffective fisheries policies programmes. The “Malthusian narrative” suggests that is driven by too many fishers chasing few fish fishing effort grows proportionately human population growth, requiring policy interventions reduce fisher access, number fishers, population. By neglecting other drivers may be more directly related pressure provide tangible levers for achieving sustainability,...
Abstract The ocean is a dynamic environment inhabited by diverse array of highly migratory species, many which are under direct exploitation in targeted fisheries. timescales variability the marine realm coupled with extreme mobility ocean‐wandering species such as tuna and billfish complicates fisheries management. Developing eco‐informatics solutions that allow for near real‐time prediction distributions mobile an important step towards maturation management ecological forecasting. Using...
The North Pacific Transition Zone (NPTZ) is known as a global marine hotspot for many endangered and commercially significant highly mobile species. In the last few decades, region has undergone unprecedented physical biological transformations in response to climate variability change. Although it anticipated that species will need adapt shift their distributions, current predictions have relied on short-term data sets or modeled simulations. This left critical gap our understanding of...
Until recently, scientists had no idea how loggerhead sea turtles (Caretta caretta) migrate from their nesting beaches in Japan to nursery grounds Baja California, Mexico. The Thermal Corridor Hypothesis (TCH, Briscoe et al. 2021) combined 16 years of satellite-tracked movement data propose an intermittent thermal corridor that allows juvenile loggerheads transition the Central North Pacific (CNP) west coast America. TCH proposes this migratory opens during anomalously warm conditions and...
Highly migratory marine species can travel long distances and across entire ocean basins to reach foraging breeding grounds, yet gaps persist in our knowledge of oceanic dispersal habitat use. This is especially true for sea turtles, whose complex life history lengthy pelagic stage present unique conservation challenges. Few studies have explored how these young at-sea turtles navigate their environment, but advancements satellite technology numerical models shown that active passive...
Abstract Interannual oceanic oscillations, climate change, and extreme events present a significant complex challenge to management of pelagic fisheries. In recent years, anomalous oceanographic atmospheric conditions have been reported across the northeast Pacific, yet research results concerning biophysical mechanisms impacting specific organisms, populations, fishery systems remain scarce. Here we discuss trends within Gulf California’s jumbo squid in context relevant drivers, ecological...
Abstract Characterizing habitat suitability for a marine predator requires an understanding of the environmental heterogeneity and variability over range in which population moves during particular life cycle. Female California sea lions ( Zalophus californianus ) are central‐place foragers particularly constrained while provisioning their young. During this time, selection is function prey availability proximity to rookery, has important implications reproductive success. We explore how...
Abstract Aim Animal tracking can provide unique insights into the ecology and conservation of marine species, such as partitioning habitat, including differences between life history stages or sexes, inform fisheries stock assessments, bycatch reduction spatial management dynamic management. Location Northeast Pacific Ocean. Methods We used satellite data from 47 blue sharks ( Prionace glauca ) to determine movements home range along west coast North America, sex–size class (immature...
Extreme climatic events are expected to become more frequent under current conditions of increasing global temperatures and climate variability. A key challenge fisheries management is understanding planning for the effect anomalous oceanic on distributions protected species their interactions with fishing gear. Atypical marine states can cause non-target shift outside normal distribution patterns, leading unwanted bycatch that threaten sustainability. Environmental indicators serve as early...
Mussel farming is a thriving industry in New Zealand and crucial to local communities. Currently, farmers keep track of their mussel floats by taking regular boat trips the farm. This labour-intensive assignment. Integrating computer vision techniques into aquafarms will significantly alleviate pressure on farmers. However, tracking large number identical targets under various image conditions raises considerable challenge. paper proposes new vision-based pipeline automatically detect...
The juvenile stage of loggerhead sea turtles (Caretta caretta) can last for decades. In the North Pacific Ocean, much is known about their seasonal movements in relation to pelagic habitat, yet understanding multi-year, basin-scale has proven more difficult. Here, we categorize large-scale 231 satellite tracked from 1997 2013 and explore influence biological environmental drivers on movement. Results show high residency loggerheads within Central a moderate Earth's magnetic field, but no...
The North Pacific Loggerhead sea turtle ( Caretta caretta ) undergoes one of the greatest all animal migrations, nesting exclusively in Japan and re-emerging several years later along important foraging grounds eastern Pacific. Yet mechanisms that connect these disparate habitats during what is known as “lost years” have remained poorly understood. Here, we develop a new hypothesis regarding possible physical mechanism for habitat connectivity – an intermittent “thermal corridor” using...
Aquaculture is an important industry in New Zealand (NZ). Mussel farmers often manually check the state of buoys that are required to support crop, which labour-intensive. Artificial intelligence (AI) can provide automatic and intelligent solutions many problems but has seldom been applied mussel farming. In this paper, a new AI-based approach developed automatically detect from farm images taken South Island NZ. The overall consists four steps, i.e. data collection preprocessing, image...
