Examination of Fish Assemblages within Sanctuary and NonSanctuary Zones of Marmion Marine Park, Western Australia.
Marmion Marine Park lies at the southern end of one of the largest reef systems in South Western
Australia. All fishing and collecting, both recreational and commercial, is officially prohibited from three
sanctuary zones in the Marine Park. Little Island is located one kilometre West of Hillarys Boat Harbour.
The little Island reefs are biologically rich, housing several rare and endangered species like cowries, sea
lions and many pelagic and demersal fish. In 1999 Little Island was made a no take fishing sanctuary
zone.
According to the Marmion Marine Park Management Plan (1992), a sanctuary zone should encompass
1/3 of all the bioregions in the area. However, the Little Island Sanctuary zone includes only 5% of the
bioregions of the park (DEC 2008). Additionally, these sanctuary zones account for only 0.44% of the
Marine Park’s area. The reef and lagoons of little Island provide intrinsic beauty and aesthetic value to
many recreational divers, boaters and swimmers. Since 1965 the increase in housing and population on
the Marmion Marine Park coastline has impacted on the park. Qualitative studies during the 1980’s
discovered a decline in several marine species contributed to by this.
The zonation of sanctuary areas contained within the Marmion Marine Park is an essential part of the
Marmion Marine Park Management plan (1992) (DEC 1999). In 2004, marine parks and reserves
conducted transect dives and baited camera counts of pelagic fish within Little Island. Information sharing
offers have been extended to DEC and have been welcomed.
Aims




Develop a Pelagic Fish Count Database inside and outside of a sanctuary zone.
Examine the effects of total fishing bans on fish stocks.
Account for the effectiveness of sanctuary zones within marine parks.
Examine the feasibility of extending sanctuary zones.
Commercial and non-commercial fishing activities constantly draw on the ocean as a source of
income and recreation. This places considerable pressures on the environment and targeted fish species,
which can easily experience population collapse. As the environment is static and constantly changing,
particularly close to anthropogenic activities, it is important to periodically evaluate structures that protect
and offer refuge to selected species. Our research will evaluate the effectiveness of marine sanctuaries;
important no fishing zone refuges, in offering protection and allowing the eventual replenishment of fish
stocks to the surrounding areas.
We will generate new knowledge on the long term benefits of a marine sanctuary in the Southwest region.
The research will help to quantitatively identify whether marine sanctuaries provide a real refuge for
targeted fish species from consumptive fishing activities. Outcomes from the research will provide marine
resource managers with the information needed to assess the value of such establishments, and whether
it is worth extending these sanctuary zones to boost fish stocks. This can also be combined with primary
data on current fish abundances to develop future marine protected areas, within the Marmion Marine
Park and adjacent areas.
Being a comparative study, two plots have been selected (Sanctuary and Non-Sanctuary) with similar site
characteristics. Should the research find it beneficial for the extension of a sanctuary, our “non-sanctuary”
site can serve as an example of a characteristic area that can be rezoned.
There is limited modification of the techniques and methodology as the project draws on these from
previous comparative marine studies in the area. These were carried out the Department of Environment
and Conservation (Dec, formerly CALM) through the use of live baited cameras, and transect dives. We
plan to use the same techniques, but with a greater number of replicate dives to generate a more precise
estimation of pelagic fish numbers.
A survey will be conducted to examine the fish assemblages of Little Island Sanctuary within
Marmion Marine Park to a selected Non-Sanctuary area within the Park. Transects measuring
approximately 300 m will be laid to transect prominent, shore-parallel limestone ridges which form
extensive reefs systems separated by sandy depressions in 3-10 m depth (Searle and Semeniuk, 1985)
over the length of the Sanctuary. These will be replicated three times approximately 50 m apart to
encompass the Sanctuary’s width. Identification of fish species in situ will be provided via video footage
1
from an underwater camera held underwater using SCUBA apparatus; video recording will be done using
a Sony miniDV recorder with frames being linked at 10 second intervals along each transect. Boat
position, heading and speed are to be logged from a differential GPS while water depth will be accessed
from the vessel’s echo sounder. Complementary diving to collect specimens will occur in the chances to
resolve ambiguities if any misinterpretations occur during analysis of video footage. A description of the
proposed research plan is highlighted below:

The research conducted on the Marmion Marine Park has the potential to result in economic and
social benefits on both a local and national level. The project is expected to conclude that diversity and
abundance of fish species is higher in the ‘no-take’ sanctuary zone in comparison to the general use
zone, thus showing clear benefits for conserving fish species. Economic benefits are expected due to the
‘spill over effects’ associated with sanctuary zones, which can considerably increase the size and
abundance of commercially targeted species. Social benefits stem for an increased level of protection for
endemic and threatened species. ‘No-take’ zones provide an improved opportunity for ecotourism and
passive recreational activities, such as dive charters run within the zone. Marine parks also represent an
opportunity for research and community education.
Although the research is clearly specific to the local region and its pressures, Marine Parks and Marine
Protected Areas have been established throughout Australia, and the number is expected to increase as
conservation becomes a major issue. The research can be used as a starting point to encourage similar
studies in other locations, including the investigation of sanctuary zone size requirements to provide
maximum benefit and sufficient buffer area. There is the expectation that the research may make
planners, policy makers and the community more aware of the benefits of sanctuary zones as a method
of preserving the marine environment and therefore influence the upgrade of new and existing Marine
Park general use zones to sanctuary zones. Although this may cause an initial catch decline as
fishermen are restricted from the zone, long-term positive economic benefits are expected due to the
increased sustainability of the fishing industry. Thus fishing can be improved with sensible placement of
sanctuary areas. Protecting marine biodiversity through an integrated ecosystem-based management
plan is essential for preservation and recovery of all species and habitats.
The research that is to be collected will be a combination of previous data from the Department of
Environment if attainable along with a collection of our own results taken from the field. The results will be
presented to the wider public by providing a detailed report that will summarise the major findings. To
further communicate the major findings and concepts explored, information will be presented as a website
that will be easy to access and use. A public forum will also be set to provide an open opportunity to
discuss within the wider community the aim of the project and results along with public feedback.
The majority of the project will comprise an equal workload ethic and responsibilities to be carried
by each member of the group. However, as for example, data collection will require boat and scuba
qualifications, members in the group that have these individual requirements will partake in these
activities. Subsequently those that do not have their diver’s ticket, contributions will be made by putting in
extra computational time entering data or other such tasks. Overall group dynamics range widely, and
have their own fields of expertise covering a diverse range of interests and areas of management (as can
be seen below).

Risk Levels
Actions
Very High
Very High: Risks are intolerable for OHS. Do not commence or continue at this risk level for OHS risks. Implement control measures to ensure the risk level is reduced. Communicate and consult thoroughly on nonHSEC risks to ensure the positive benefits outweigh the negative impacts.
High
High risk: Risk is undesirable. Verify, and where possible quantify, the accuracy and certainty for the existing risk level. Implement control measures to ensure risk level is reduced to or is confirmed to be As Low As
Reasonably Practicable (ALARP). Operation at this level requires management approval.
Medium
Medium risk: Are only tolerated if examination proves them to be ALARP. Implement management plans to prevent the occurrence and monitor for changes. Reduce to Low Risk if the benefits outweigh the cost.
Low
Low risk: Are acceptable. Review at next review interval.
