Release and recovery files from the world's five major constituent-based billfish (Istiophoridae) tagging programs were assembled into a single composite database. Data sources included National Marine Fisheries Service's (NMFS) Cooperative Tagging Center (MIA) in Atlantic Ocean, NMFS's Billfish Program (LJA) Pacific Indian Oceans, Australian New Zealand Game Fish The Foundation's (TBF) program Atlantic, Oceans. Results for main target species, including black marlin (Makaira indica), blue...
Abstract Many taxa are undergoing distribution shifts in response to anthropogenic climate change. However, detecting a signal mobile species is difficult due their wide‐ranging, patchy distributions, often driven by natural variability. For example, difficulties associated with assessing pelagic fish distributions have rendered fisheries management ill‐equipped adapt the challenges posed change, leaving and ecosystems vulnerable. Here, we demonstrate value of citizen science data for...
Abstract Tiger sharks were sampled off the western (Ningaloo Reef, Shark Bay) and eastern (the Great Barrier Reef; GBR, Queensland New South Wales; NSW) coastlines of Australia. Multiple tissues collected from each shark to investigate effects location, size sex on δ 13 C 15 N stable isotopes among these locations. Isotopic composition in reef seagrass habitats (Shark Bay, GBR) reflected seagrass-based food-webs, whereas at Ningaloo Reef analysis revealed a dietary transition between pelagic...
In this paper we combine analyses of satellite telemetry and molecular data to investigate spatial connectivity genetic structure among populations shortfin mako (Isurus oxyrinchus) in around Australian waters, where species is harvested recreational commercial fisheries. Mitochondrial DNA suggest matrilineal substructure across hemispheres, while nuclear indicate may constitute a globally panmictic population. There was generally high within waters. Assessing the Indian Ocean basin, as well...
The welfare of fishes and aquatic invertebrates is important, several jurisdictions have included these taxa under regulation in recent years. Regulation requires use scientifically validated criteria. This why applying Mertonian skepticism toward claims for sentience pain sound prudent, particularly when those are used to justify legislation regulating the taxa. Enacting without strong scientific evidence a societal political choice that risks creating interpretational problems as well...
Abstract Long-term continuous datasets that record fishery catch are key to predicting and managing changes in fisheries. Unfortunately, long-term rare for recreational fisheries, which hinders our ability understand within these Here we use several unconventional datasets, including tournament tagging program data, assess composition over time the Australian east coast marlin fishery. We found significant species size of time. In 1930s, was solely comprised striped ( Kajikia audax ) black...
Abstract Obtaining reliable estimates of important parameters from recreational fisheries is problematic but critical for stock assessment and effective resource management. Sampling methodologies based on traditional design‐based sampling theory, inadequate in obtaining representative catch effort data, social or demographical characterization, fisher behaviour small hard‐to‐reach components within (e.g. specialized sport fisheries) that may account the majority some species. A model‐based...
Abstract Understanding the processes driving species distributions is a key question in ecology, yet obtaining pertinent data for many can be challenging. Tag-recapture from voluntary recreational fisheries programmes an undervalued citizen science resource and provide valuable observation records data-poor species. Here, we highlight utility of such by compiling four tag-recapture datasets (n = 20 878 tags) to describe movements distribution piscivorous predator, tailor Pomatomus saltatrix,...
Pop-up satellite tags were deployed on seven black marlin, Makaira indica,in the north-western Coral Sea, to examine movement, post-capture mortality and habitat preferences. Five of these popped up transmitted positions, detailed data diving behaviour, ambient water temperature daily movement received via ARGOS transmission from two tags. One tag was later found a beach, allowing complete archival set be downloaded geolocation estimates provided by software on-board pop-up those based sets...

The black marlin Istiompax indica is a highly migratory species and as result expected to show little genetic population structure throughout its broad geographic range. Tissue samples from 183 I. were collected three regions within the central Indo-Pacific analysed using mitochondrial nuclear DNA markers. Nuclear heterogeneity was found among populations in south-western Pacific Ocean, eastern Indian Ocean South China Sea (significant FST values of 0.013–0.037). Combining information...
Abstract Background and aim Billfish are epipelagic marine predators facing increasing pressures such as overfishing rising global temperatures. Overfishing is a major concern, they caught by industrial longline fishers targeting tuna. targeted multiple fishing sectors, which provides food, socio‐economic cultural benefits. To support effective billfish management conservation, it essential to understand their spatial distribution the environmental factors that may influence it. Location The...
The black marlin ( Istiompax indica ) is a highly migratory billfish that occupies waters throughout the tropical and subtropical Indo-Pacific. To characterize vertical habitat use of I. , we examined temperature-depth profiles collected using 102 pop-up satellite archival tags deployed off east coast Australia. Modelling environmental variables revealed location, sea-surface height deviation, mixed layer depth dissolved oxygen to all be significant predictors use. Distinct differences in...
We investigated whether commercially landed black marlin Istiompax indica were being misidentified by fisheries observers operating throughout the Pacific Ocean. Of 83 samples reported as I. indica, 77% genetically identified to be blue Makaira nigricans and 2% striped Kajikia audax. The high rate of misidentification places considerable uncertainty over historic catch ratios Indo-Pacific stock assessments relying on validity these data.
Increasing fishing pressure and uncertainty surrounding recreational catch effort data promoted the development of alternative methods for conducting fisheries research. A pilot investigation was undertaken to engage Australian game community promote non-lethal collection tissue samples from black marlin Istiompax indica, a valuable recreational-only species in waters, purpose future genetic Recruitment anglers achieved by publicizing project magazines, local newspapers, social media, blogs,...
Abstract Archived specimens are highly valuable sources of DNA for retrospective genetic/genomic analysis. However, often limited effort has been made to evaluate and optimize extraction methods, which may be crucial downstream applications. Here, we assessed optimized the usefulness abundant archived skeletal material from sharks as a source temporal genomic studies. Six different methods extraction, encompassing two commercial kits three protocols, were applied material, so‐called...
Abstract Over the last century, many shark populations have declined, primarily due to overexploitation in commercial, artisanal and recreational fisheries. In addition, some locations use of control programs also has had an impact on numbers. Still, there is a general perception that large ocean predators cover wide areas therefore their diversity less susceptible local anthropogenic disturbance. Here we report temporal genomic analyses tiger ( Galeocerdo cuvier ) DNA samples were collected...
