A large part of my PhD involves working with researchers from NSW DPI and UOW to try and understand the movement patterns of fishes found on marine sands. And our recent paper (open access and free to read here) on blue-spotted flathead is the first piece of the movement puzzle Continue reading
Earlier this year my co-authors and I published a paper in Diversity and Distributions that examined a cost-effective way of predicting reef biodiversity for conservation purposes. Here is some background on the issues surrounding the design of Marine Protected Areas (MPAs) and a brief summary of our research findings.
A quick post to give a bit of background on the PhD research I am carrying out at present, as always, questions, advice and constructive criticism is welcome.
The vast unknown: assessing the conservation of soft sediment fish diversity
Sand. That grainy stuff that covers vast swathes of the ocean floor. Although perhaps to the casual observer this habitat isn’t as exciting as coral reefs or seagrass meadows, delve a little deeper and you will discover that there is a whole lot happening out in the vast sandy stretches of the ocean. Sand or soft sediments cover most of Australia’s state and national waters and are heavily exploited by commercial and recreational fishing.
Surprisingly, there has been little research into fish ecology on these habitats, with most effort expended on assessing fish found on coral reefs, rocky reefs, estuaries and seagrass. For a habitat that is so heavily exploited, there is a serious and immediate need to determine the basic ecology of the fish species present, the effects of fishing and also to examine the success of conservation efforts in place. More than 70% of Australia’s marine protected areas cover soft sediments, yet to my knowledge, both nationally and internationally there have been no studies looking at the effectiveness of marine protected areas in conserving soft sediment fish.
My PhD aims to examine Continue reading
