Abstract
Following an introduction to the broader context of the Symposium, the scope of the
oral presentations is summarized under three themes: a global synthesis of fisheries
impacts in different ecosystems; an overview of the methods available for quantifying
ecosystem impacts; and the integration of fisheries and environmental management.
The presentations generated substantial evidence that marine ecosystems have been
impacted by fishing. Also there appeared to be a broad consensus that the present
approach to achieving conservation objectives of fisheries management does not
sufficiently take into account ecosystem considerations. There was not, however, a
consensus on what additional restrictions are required, or on what features of
ecosystems need to be protected. A way forward is to add ecosystem objectives to the
conservation component of fisheries management plans, as well as to the management
plans for other ocean-use sectors. The aggregate ocean-use activities would need to be
evaluated in a nested manner, at a range of geographic scales, in relation to the more
broadly defined conservation objectives. It is suggested that the geographic scales for
evaluation of ecosystem considerations could be defined in a pragmatic manner based
on the somewhat artificial boundaries of political and administrative systems already
in place. The six conservation objectives proposed are maintenance of (1) ecosystem
diversity, (2) species diversity, (3) genetic variability within species, (4) directly
impacted species, (5) ecologically dependent species, and (6) trophic level balance.
Indicators for each objective are discussed, as well as reference points that would
trigger management actions. Such a broadening of conservation objectives for fisheries
mangement would require both enhanced monitoring and a greater workload added to
the process of provision of scientific advice through peer review. Of equal importance
would be the challenges of establishing a governance framework to address multiple
uses of marine resources. The spirit of the Symposium was that these coupled scientific
and governance challenges will be very stimulating.
