Instructions for carrying out grey nurse shark surveys
Things to record on the dive:  Total number of sharks sighted  The sex of each shark (if not identified use „unknown‟ category)  Length of each shark (measure up against another diver)  Temperature of the water at the bottom (digital gauge only)  Behaviour  Pregnant  Special markings (scares, damaged fins, please note where it is on the shark)  Fishing Tackle attachments (hooks, ropes, etc. please note where it is on the shark)  Visibility  Number of divers  ID Tags (colour and number)

 Photographs & video. Please forward any photographs and video footage (regardless of quality) to assist in an invaluable, non-invasive study to monitor the grey nurse shark population and their migration along the east coast. If possible, photos of distinguishing features (e.g. scars and fishing tackle) and photos that include from the 1 st dorsal fin to the end of the caudal (tail) where dark spots are concentrated are very useful to identify individuals Please e-mail or post photos to the address below or contact QPWS Cleveland. All photos and video footage will remain the property of the owner and will be used for research purposes only.

 Recording the sex of each shark. To differentiate a male from a female you must look underneath the shark at the pelvic fins. Males have claspers extending from the pelvic fins (see diagram). If unsure of the sex of the shark you sighted please record it as “unknown”.  Important sites for grey nurse sharks in Queensland. There are 14 identified sites in southeast Queensland where grey nurse sharks have been recorded. Please report sightings or the absence of sharks if you dive at any of these sites, or anywhere else you may see them.        Flat Rock Wolf Rock Cherub‟s Cave China Wall Henderson Rock Hutchison Shoal Roberts Shoal        Shag Rock Flinders Rock Boat Rock The Sevens Smiths Rock Brennan Shoal Jew Shoal

 Do not omit reporting the dive due to the absence of sharks. Please report zero sharks at that site. The fact that there were no sharks on a dive is just as important as if there were sharks on the dive.  Identification tags. QPWS and NSW Fisheries have conducted a series of tagging programs to identify and understand the movement of the east coast grey nurse shark population. When diving

please note whether tags are present, the colour of the tags and the number on the tag. If you cannot see the number or colour please still make note of the sighting as “U” (unknown) in the tables provided on the data sheet. Entry and use provisions for grey nurse shark areas* When diving in a grey nurse shark area, divers must not:

  

Dive between 6pm and 6am; Touch or feed a grey nurse shark; Chase, harass or interrupt the swimming patterns or interfere with a grey nurse shark‟s natural behaviour;  Attempt to block cave entrances or gutters, or entrap grey nurse sharks;  Use mechanical or electro-acoustic apparatus including, but not limited to, scooters, horns and shark-repelling devices. Commercial operators may use equipment required for diving under the Work Place Health and Safety Act 1995; and  Dive as part of a group totalling more than 10 divers. Tourist operators may have groups of up to 12 divers, provided the additional divers are either instructors or guides. Divers can face fines up to $7500 In addition to diving provisions listed above, tourist operators with diving as an activity on their Marine Parks (Moreton Bay) permit and dive clubs that are diving in a grey nurse shark area must:



Ensure that before a person enters the water in a grey nurse shark area, the diver is given information about the restrictions for the zone; and the restrictions on entering or using the grey nurse shark area; and  Display the entry and use provisions for grey nurse shark areas in a prominent position in dive shops or clubs that operate or promote diving trips within Moreton Bay Marine Park and on board all diving boats. Tourist operators and dive clubs can be fined up to $750. *Grey nurse shark areas Cherub‟s Cave area consists of the area enclosed within a 1.2km radius of the point 27°07.67‟ south, 153°28.67‟east. Flat Rock area consists of the area enclosed within a 1.2km radius of the point 27°23.41‟ south, 153°33.07‟ east. Henderson Rock area consists of the area enclosed within a 1.2km radius of the point 27°07.92‟ south, 153°28.71‟ east.  Recording and returning data. Please retain a copy of the information you collect just in case it is lost in transit, and return the form immediately after the survey dive is completed by fax, post or email. Dive operator record data should be submitted on at least a three monthly basis.
