Shark Search Indo-Pacific: finding sharks and conservation solutions in the Big Ocean

Dr Andrew Chin is based at the Centre for Sustainable Tropical Fisheries and Aquaculture – James Cook University and is the current president of the Oceania Chondrichthyan Society. He is also the Programme Director of Shark Search Indo-Pacific, a project that I personally find incredibly interesting and have been following closely. Andrew stopped by Fish Thinkers to give us the inside scoop on Shark Search Indo-Pacific in the guest post below: Continue reading

Dragging the chain – does anchoring by large ships impact our marine life?

I’m excited to announce that I’ll be joining a multidisciplinary team of researchers, supported by UOW’s Global Challenges program, to investigate the potential impact of large ships anchoring on our marine life and seafloor habitats.

As an island nation, we are heavily dependent on shipping, with large ships transporting 99% of our trade by volume. Prior to entering our ports these large vessels may anchor in deep water, often for many days, waiting for their turn to exchange cargo.

Now when I say ‘large’ I mean freakin huge (see pic below). These ships are between 200-300 metres long and to anchor they require an anchor chain up to 250 metres long where each individual chain link can weigh up to 200 kilograms! Continue reading

Close to home: what drives the distribution of intertidal rockpool fishes?

Read below for a great summary by Kai Paijmans on his research examining the distribution of rockpool fishes. Kai’s project was for a 3rd year UOW research subject, where he was supervised by Dr. Marian Wong and Ben Gooden.

Close to home: what drives the distribution of intertidal rockpool fishes?

Rocky intertidal shores are right on the edge of our home – between the known of the shores and the vast unknown of the world’s oceans. Although regularly overstepped by many of us, rockpool life is largely overlooked in favor of large charismatic and untouchable creatures of the open and comparatively inaccessible ocean. It is important to understand the ecological processes occurring on rocky shores as they are right on our doorstep; heavily used for, and potentially impacted upon by recreation. Continue reading

Surrogates for temperate reef biodiversity and their use in conservation

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.
