Wild
Fisheries with a Future
The Lakes and Coorong Commercial Fishery is an
inland and inshore waters community fishery, in the upper southeast
region of South Australia.

Estuarine, saltwater and freshwater species are
harvested by the license holders stretches in the area from the Wellington
ferry on the River Murray, the waters of Lakes Alexandrina and Albert,
the waters of the Coorong lagoons and estuary, and the beach and coastal
waters from the Murray Mouth to Kingston SE.
It has been commercially fished since 1846, with
a number of generational fishing families (some going back 5 generations),
still conducting their activities in the area. This gives fishers
an intimate knowledge of the environment and an understanding of the
history that has shaped the development of the fishery.
This in addition to the owner-operator policy and
the commitment to low impact fishing methods means the fishery has
an ecosystem based focus and strong community links. The pro-active
approach to their business has fishers participating in numerous activities
and initiatives.
It has become a highly modified system, following
the construction of barrage network from 1935 to 1940, when 89% of
estuary turned into fresh water. The impacts of man’s interference
in the natural regime include reverse/summer flooding, riparian zone
modification, introduced species, massive water usage and flow modification
and pollution. Yet despite this 90% of value comes from 10% of the
original estuary with the landed wharf value of the fishery approx.
$5.4m (Econsearch Report 2003/04).
Ethical,
Sustainable Harvest
The diversity of available harvest represents one
of the keys to the long-term sustainability of the fishery. Since
fishers can shift effort to different targets should priority species
be scarce, they are not forced to deplete stocks just to make a living.
The main species fished are mulloway, flounder, yellow-eye mullet,
cockles, black bream, bony bream, redfin perch, callop, and European
carp. The gear types used are slightly modified versions of traditional
aboriginal gear types.
Fishing methods utilise low mechanisation coupled
with highly energy efficient netting and manual harvest types. This
results in low by-catch, highly specific methods operated by well-trained
operators with decades of experience with the ecosystem and it’s
fish.
The modification of the ecosystem means there is
a diverse range of habitats (freshwater, estuarine, marine and hyper
saline areas.) The advantages of being a multi-species, multi-gear
fishery is that there can be a rotational harvest system, which shifts
effort from one species to another when one becomes financially non-viable
to target, or spreads effort across several species when conditions
are ideal.
Management of the Fishery
The commercial fishery is managed using a complex
mix of input and output controls aimed at matching harvesting capacity
with resource availability and controlling growth in collective harvesting
capacity.
Existing controls include limitations on the number
of licences, a wide range of gear restrictions, area and time closures.
There are also a limit on the number of commercial agents permitted
to assist fishing operations and size limits for individual species.
The majority of the management controls used today
have been in place for many years. These are all outlined in the recently
released Lakes and Coorong Fishery Management Plan 2005

A new managment structure was implemented in 2007 with the demise fo the FMC's. It was up to industry to create a managment advisory committee known asthe Lakes and Coorong Fishery Consultative Committee.
The committee comprises of the following representatives:
Fishing Industry
Garry Hera-Singh
Steve Alexander
David Reichelt
Robert Brooks
Tracy Hill
Dept Environment & Heritage
Simon Oster - (Head Ranger of the Coorong National Park or proxy)
Ngarrindjeri
Derek Walker (or nominated proxy)
Local Government
Roger Strother - Coorong Council Mayor
Trent rusby, Councillor Alexandrina Council delegate
Conservation
Alex Gaut - CCSA Marine Planning Officer
Meetings are also attended by PIRSA Fisheries Managers, PIRSA Compliance, SARDI, and committee support officer Neil McDonald from Wildcatch Fisheries SA.
Invitations are extended to other relevant agencies or individuals when further expertise or advice is required.
A Pipi Sub Committee has also been formed to deal with specific issues for that species.
The Cost recovery (License fee setting) process is managed by PIRSA Fisheries and run separately to the other managment issues.
