A new paper from the Laboratory reports on the degree of connectivity in blue marlin populations across the Pacific Ocean using genomic markers (6204 SNP and 17 microsatellite loci) . It provides much-needed new information for the management of this highly migratory and highly sought-after species.
A new analysis from the Molecular Fisheries Laboratory has been published. It compares simulated and empirical genetic data to refute the idea of a single, long-distance migration event for a commerically-important species in Queensland (Mugil cephalus) and demonstrates the feasibility of spatially-realistic ecological-genetic scenario testing.
While the majority have no issues, a few people are having trouble downloading software. We think that occasionally the server has exceptionally slow download speeds. This leads to get empty folders or software that doesn't execute. If this happens, try downloading at another time. If that doesn't work, use the Contact Us page and I can send you a dropbox link instead. Best, Jenny Ovenden
"Sweepstakes reproductive success is absent in a New Zealand snapper (Chrysophrus auratus) population protected from fishing despite ‘tiny’ Ne/N ratios elsewhere" is available as early on-line from Molecular Ecology. Here is the link.
Congratulations to MFL senior fellow and ABARES scientist Andy Moore who received $1,072,045 from the Fisheries Research and Development Corporation (FRDC) to conduct a National Social and Economic Survey of Recreational Anglers in conjunction with the University of Canberra. The study will commence early 2019 and run for 12 months. The survey will collect information on participation, catch and release, expenditure, regional economic flows, social benefits, bait use, biosecurity and wellbeing associated with recreational fishing throughout Australia. The study will implement novel techniques to screen and survey the Australian population and determine technical biases in survey methodologies. Next trip to MFL at UQ, Andy will talk about the details of this project.
Ever wondered about the effective population size of your favourite species? NeOGen allows you to make a population of many thousands of individuals matching a species with overlapping generations and the life-history characters that you enter. Once you set this up, you can try different sampling schemes (varying numbers of individuals and genetic loci) to see how well the estimate matches the 'true' effective size of the population. You can also generate populations of different sizes to match the effective size that you have measured in the wild. Read more and download it here. Read the paper here.
Sam Williams completed his PhD project on black marlin, and graduated from the University of Queensland in December 2018.

For those interested in elasmobranch research, there is a new publication coming soon from CRC Press. If you are interested in population genetics, then go to this chapter for the latest information.
