Positive Development From Vicious Circles to V

Lower Murray Lakes and Coorong Fishery
At a time when fisheries are collapsing globally, there are also valuable lessons to be learned 
from the Lower Murray Lakes and Coorong fishing community. Commercial fishing has taken 
place in Lakes Alexandrina and Albert, the Coorong, and the Southern Ocean, around the 
mouth of the River Murray in South Australia, since 1846. The completion of the Murray 
Mouth Barrages in 1940 turned the lakes to freshwater, resulting in the loss of 89 per cent 
of the richest fishing grounds. Only a few resilient families remained. In the late 1980s, the 
fishers again came under pressure to assess, justify and articulate their activities. It helped 
to focus the group to reaffirm positive processes and develop additional rules to ensure that 
their fishery remained sustainable. 
Similarities between the two groups in the studies 
• 
Recognition that healthy ecosystems are crucial to livelihoods. 
• 
The use of local knowledge and vernacular processes, developed over generations of 
observation and experience, to work in harmony with local ecosystems.
• 
Vulnerable geographic location. Ecosystems and communities at the bottom ends of 
rivers ‘dying from thirst’, as a result of excessive upstream diversions, is a global issue.
• 
Both bioregions have been seriously impacted by pre-ecological river regulation 
priorities.
• 
Adaptive management: a timely response to a situation with scientific and local 
(sometimes including intergenerational) knowledge.
• 
Diversity. Neither group is confined to one ecosystem or one product/species for 
their livelihoods. Fishers can move between freshwater, estuary and the ocean. During 
droughts, floodplain farmers make a living from forest products.
• 
Self-imposed rules to improve the sustainability of species and natural habitat.
• 
Independent accreditation of activities (eg Biological Farmers of Australia and Marine 
Stewardship Council). 
• 
Recognition of the importance of cooperation for survival through the establishment of 
industry associations. 
• 
Value-adding to maximize returns while reducing impacts (eg farming organically
operating fish restaurants). 
• 
Appreciation of the importance of ongoing communication with Australian society. 
Centralized technocratic bureaucracies can make important but limited progress towards sus
-
tainability. Community groups with thorough knowledge of local bioregions must be embraced 
as authentic partners to fine-tune and accelerate procedures.
