This discussion of fisheries
science ecological knowledge is divided into three parts:
First, we have the perspectives of fisheries scientists.
Next, we focus upon social scientists and their perceptions
of fisheries science ecological knowledge. Finally, our
attention will shift to the position of representatives of
user groups. This also includes their experiences with
fisheries science. Although the summary focusses upon
fisheries science ecological knowledge, it also incorporates
discussions of local ecological knowledge (LEK). This is
unavoidable since most papers deal, in some way, with both
forms of knowledge
The View From Fisheries
Science
Although there were some
differences in the issues raised, fisheries scientists
tended to converge on areas surrounding how fisheries
science has been conducted, as well as the need for better
science in understanding the ecosystem. At times, this also
included an endorsement of LEK as a basis for testing
hypotheses through the scientific method.
- Fisheries Science and Stock
Assessments: The fisheries scientists agreed that
research has largely focussed upon single stock
assessments. Some argue that what is needed is a
multi-species stock assessment model which can better
incorporate the permutations within an ecosystem. One
fisheries scientist indicates that "...ecosystems
comprise a complex web of interactions..." and that the
removal of one element such as cod will affect the rest
of the ecosystem but not much is known about this. The
scientist adds that while multispecies modelling is
necessary not much effort has gone into this direction.
Another scientist concurs that much Department of
Fisheries and Oceans (DFO) efforts have been around
single specieis assessments, but that efforts at
developing ecosystem models are based upon directing that
information at the species level. A compromise is
suggested whereby a hybrid model based upon
single-species population can be used to include species
interactions. Another scientist notes how the
non-selective nature of the otter trawl has been used to
collect data instrumental to the determination of a
"...number of species and size classes at once." Still
another scientist states that ecological knowledge has,
to this point, dealt with areas such as population
dynamics, growth, reproduction and mortality. In summary,
while most fisheries scientist point to the importance of
the ecosystem, they concur that, to date, most research
deals with the counting of fish.
- Science and LEK: The
importance of science as a method is raised in most of
the papers submitted by fisheries scientists. This is
usually contrasted with LEK. While sympathetic to the
qualitative nature of LEK, one writer argues that it
needs to be subject to testable hypotheses and this takes
place within the realm of science. The author points to
issues such as how fishers' knowledge of the spatial
areas within fishing grounds can improve upon scientists
stratify the ocean in order to study fish populations.
Another adds that information from mathematical models
are internationally accepted, and that science is for the
public good. The scientist stresses that LEK is often
used to support more narrowly based resource
exploitation. In a statement that concurs with this
position, another scientist points out that LEK is only
useful at the level of the individual organism, it is not
useful for ecosystem models which can only be delivered
by scientists. Another scientist, while being aware of
the extent to which institutional factors can compromise
science argues that the scientific method is a
"...simple, transparent and robust method of acquiring
and demonstrating knowledge..." This is more important
for public policy because LEK is 'localised' and not as
influential. Still, this scientist appreciates the need
for incorporating LEK into scientifically testable
research hypotheses.
The View From Social
Science
Although fisheries scientists are
quite aware of the context that they have to operate in, one
succinctly states that they do not have live with the
consequences of their research. This point is also made by
one of the social scientists. For the most part, comments
pertaining to the contextual nature of fisheries science
ecological knowledge are made by the social scientists.
Although some refer to the same issues as do the fisheries
scientists (e.g. stock assessments), the social scientists
are often quite strident in adressing the values and
material interests behind fisheries science. A second issue
that runs through some of the papers is the hierarchical
relation between fisheries science and LEK, and the dangers
of subordinating the latter to the former. Finally, others
problematise the very issue of LEK in the same way as they
probably would fisheries science ecological
knowledge.
- Fisheries Science, Values
and Material Interests: Most of the social scientists
argue that fisheries science, and science in general, has
to be related to its context. One researcher argues that
DFO fishery science, especially since the introduction of
the 200-mile limit, has been connected to a developmental
logic which encourages overfishing. Another adds that
science is built upon a value system. Even the most
'objective data' are based upon human perceptions which
are selective. The 'impartiality' of fisheries science is
questioned by another observer who indicates that values
are implied in the categories that are constructed by
humans. This writer adds that by dealing with categories
as if they are 'real', science cannot deal with the
things which are meaningful for human
existence.
- Fisheries Science, Social
Science and LEK: A dominant theme here is that all
knowledge reflects social power. One social scientist
states that all forms of knowledge, including fisheries
science management models, are forms of folk knowledge
connected to '...field of social power." Another writer
argues that fisheries biologists and economists are
better (or perhaps more successful) social theorists than
sociologists in that their assumptions of society are
more readily incorporated into fisheries policies. This
is despite the weaknesses in the predictions offered by
bioeconomic models based upon the 'tragedy of the
commons'. The bioeconomic model is based upon assumptions
of human nature which are more readily incorporated into
public policy than the messier and more uncertain
dimensions of co-managment models favoured by
sociologists and anthropologists. While reflecting upon
field research, another social scientist notes the power
of biology in that social research on LEK has to be
translated into a language which will be acceptable to
biologists. In dealing with areas as diverse as the use
of First Nations LEK in Environmental Impact Assessments
and the divergence among fish harvesters' perceptions of
LEK, other writers noted both the problems of having LEK
incorporated into scientific research plans and the
dismissal of LEK that is variegated. One researcher notes
that while LEK is endorsed by DFO only minimal funding is
earmarked for this type of research.
- Problematising All
Knowledge: One writer adds that social science, since
it deals with meanings integral to the human experience,
it is often perceived as subjective and invalid by the
more detached framework of natural science. Natural
science is often validated because of its connection to a
method of inquiry. Despite this claim, this writer and
others are wary of the extent to which critiques of
'official science' have led to an uncritical endorsement
of LEK. One researcher is acutely aware of this for
Native fisheries. Industrialisation has had far reaching
consequences for the Native communities in British
Columbia. Due to this, any reference to LEK must be
treated with caution.While this writer does not reflect
directly upon science, this research may be an example of
how the intertwining of science and industrialisation
impacts upon LEK. Another social scientist argues that
much writing on the fisheries links LEK to
sustainability, however, this is rarely demonstrated.
This raises the issue of the need to connect all
knowledge claims to critical scrutiny. The researcher
adds that the cultural context can serve to constrain the
operation of science. An example is the failure to
investigate the impact of the ostensibly benign cod trap
upon stock depletion. Here, the problem may be the lack
of science.
The View From Harvesters'
Representatives
Harvesters' representatives also
reflect upon the issue of fisheries science ecological
knowledge. This is based upon actual experience with the
power of such knowledge and the problem of not being taken
seriously in management plans.
- The Power of Fisheries
Science: One representative notes that fisheries
management needs to be more sensitive to ecological
concerns, and that this can be best achieved through
community-based management. However, when fish harvesters
point to problems they are only used as data gathering
devices by DFO scientists. This representative argues
that they need to be systematically incorporated into
conducting research. This problem is also noted by
another harvesters' group representative. This individual
adds that DFO research is too tightly connected with
quantitative stock assessments, and that fishers'
knowledge is more compatible with more broadly based
biological and ecological information. Furthermore,
"...respected and experienced fishers need the same level
of credibility as established scientists."
- LEK and Management
Plans: One of the more optimistic representatives of
a harvesters' organisation referred to the development of
a fisheries database through the collaborative efforts of
DFO scientists and LEK. This overcame the problems of
trust that existed prior to the development of the
database. Attention was given to the need to use good
communication in fostering trust. This dovetailed with
the concern of one social scientist for the need for
communication and alternative forms of dispute resolution
in creating conditions where fisheries science and LEK
can meet. Finally, one representative noted that local
lobster fishers have to work in partnership with fishery
scientists if the fishery is to become sustainable. This
can be accomplished through conservation and enhancment
measures which are locally-based.
Conclusions
The objective today is to discuss
fisheries science ecological knowledge. Despite my original
intention to deal with that issue alone in this summary of
the papers, this proved to be virtually impossible. Most
submissions dealt with fisheries science and its relation to
LEK. In general, three main issues stand out. While acutely
aware of the limitations of stock assessment science,
fisheries scientists are more concerned with the method of
doing science. Social scientists are more likely to discuss
fishery science within its wider context.Hence, whose
interests does science serve? What values are at work? What
is the relations between science and LEK? Finally, the
representatives of harvesters' groups are more likely to
view science as a signficant form of power in their
day-to-day lives. They raise the issues of trust and of not
having their knowledge claims taken seriously.
