Abstract Permeable phylogeographic barriers characterize the vast open ocean, boosting gene flow and counteracting population differentiation speciation of widely distributed migratory species. However, many species consists distinct populations throughout their distribution, evidencing that our understanding how marine environment triggers divergence are insufficient. The sailfish is a circumtropical highly billfish inhabits warm productive areas. Despite its ecological socioeconomic...
Context Currently, little information exists describing the population structure of great hammerhead sharks (Sphyrna mokarran) in Australian waters. Aims This study used single nucleotide polymorphisms to investigate fine-scale S. mokarran across Indo-Pacific. Methods DNA was extracted from 235 individuals six locations and a Red Sea outgroup. Population parameters were calculated visualised test structuring locations. Key results No observed for However, occurred all when compared...
Abstract Background Acoustic telemetry has become a fundamental tool to monitor the movement of aquatic species. Advances in technology, particular development batteries with lives > 10 years, have increased our ability track long-term patterns many However, logistics and financial constraints often dictate locations deployment duration acoustic receivers. Consequently, there is compromise between optimal array design affordability. Such can hinder marine animals over large spatial...
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.
Context In Australia, the health of our marine, estuarine and freshwater fishes are critical importance. The aquatic marine ecosystems, that occupy them each have an important role in country’s ecological, economic, cultural social wealth. Climate change, resource over-exploitation, invasive animals diseases, habitat degradation just a few burgeoning threats researchers managers must address to ensure prosperity Australia’s natural fisheries resources. addition, differences legislative...
Changes in ocean characteristics can cause shifts the geographical range of marine species as animals are forced to acclimate or move maintain position suitable conditions. Dolphinfish Coryphaena hippurus a highly migratory epipelagic species, whose temporal and spatial movements have been linked changes characteristics. Climate change is causing rapid these characteristics, so it critical understand how future attributes might affect pelagic fish distributions. We Investigated net...
The black jewfish ( Protonibea diacanthus ) occurs in tropical coastal waters throughout the central Indo‐Pacific. It has long been valued as an important recreational and artisanal fishery species but become increasingly targeted by commercial fisheries due to demand for its large swim bladder. To better understand how changes fishing pressure may impact sustainable exploitation of P. populations Eastern Australia, we evaluated reproductive biology across two management regions Central...
The grass emperor Lethrinus laticaudis is a coral reef fish that has high value to fisheries and vulnerable overharvesting. complete mitochondrial genome was assembled from approximately 5.5 million reads produced by Illumina MiSeq. 16,758 bp consisted of 13 protein-coding genes, 22 transfer RNA genes two ribosomal (12S 16S). RNAs order orientation on as well the A + T base content (50.7%) similar what found in other Teleosts. phylogenetic tree with most closely related species available...
Two complete mitochondrial genomes of the black marlin Istiompax indica were assembled from approximately 3.5 and 2.5 million reads produced by Ion Torrent next generation sequencing. The 16,531 bp 16,532 in length consisting 2 rRNA, 13 protein-coding genes, 22tRNA coding regions. They demonstrated a similar A + T base (52.6%) to other teleosts. Intraspecific sequence variation was 99.5% for three I. mitogenomes 99.7% X. gladius. lower value (85%) found platypterus genbank accredited...
