The Whitsunday Local Marine Advisory Committee (WLMAC) have arranged Mike Cappo to come to our region on Monday 11th April 2011 to deliver his fascinating presentation – please see abstract below.
Mike recently presented at the Whitsunday 'Eye on The Reef' workshop and the feedback on his presentation was fantastic. This is science at its best and is most entertaining. We encourage you to take the opportunity to attend this forthcoming free presentation. This presentation is open to all. Please forward this invitation to anybody and everybody who might be interested in the Great Barrier Reef, particularly the fish side of the reef.
Hope to see you there,
Tony Fontes
WLMAC Chair
Presentation from Mike Cappo – Australian Institute of Marine Science (AIMS)

When: Monday April 11
Time: 7:00 pm
Where: Reef Gateway Hotel Conference Room
Cost: Free to attend & Everyone welcome.
Refreshments & Finger Food provided
The bar: Will be open for purchases.
ABSTRACT – Mike Cappo (AIMS)
Counts by divers showed a rapid rise in coral trout populations on shallow reefs closed to fishing in 2004, but the deeper "reds grounds" have been inaccessible to fish scientists until the development of baited video techniques.
In this talk I will present four years of data counting and measuring deep-water reds, coral trout, tusk fish and reef sharks (including tigers and hammerheads) from three types of "shoal ground" with "Baited Remote Underwater Video Stations" {BRUVS} that can film down to 100 metres and are made from cheap components. On average, the results showed more fish and sharks in the green zones – but the picture was not consistent for all locations and all habitat types.
I will illustrate these differences with "highlights of play" video from the different types of shoals, and attempt to explain them with seabed swathe-maps.
I will also argue that the public debate over the role of "green zones" is focussing only on one side of the coin – fisheries management – yet the science underpinning the zoning had a broader focus on enhancing resilience of natural systems. In that regard, line-fishing is a disturbance because it removes predators.
I will show how we have mounted actual fish counts, video and pictures of the seabed on Google earth and YouTube to let the public make up their own minds . . . a picture speaks a thousand words.
