There has been a lot of literature on the optimisation of multi-species
fisheries over the years, including
Silvert, W., and W. R. Smith. 1977. Optimal exploitation of a multi-species
community. Math. Biosci. 33:121-134.
and an entire volume on the topic,
"Multispecies Approaches to Fisheries Management Advice," M. C. Mercer, ed.
1982. Can. Spec. Publ. Fish. Aquat. Sci. 59:163-169.
The problem is not that there is a shortage of research on the topic, but
rather the reluctance of managers to implement it.

Hi
Kellner et al.(2010) from UC Davis, Davis CA has a recent (Jul 2010) article
that may be of interest to you and others.
Optimizing for multiple species and multiple values: tradeoffs inherent in
ecosystem-based fisheries management
J. B. Kellner, J. N. Sanchirico, A.Hastings & P.J. Mumby (2010)
Here is the link

Abstract:
http://onlinelibrary.wiley.com/doi/10.1111/j.1755-263X.2010.00132.x/abstract
They use 5 model scenarios including optimal single species, optimal
two-species and optimal multiple species management scenarios.

Subject: [ECOLOG-L] ecosystem based fisheries management
Are there any fisheries in the world that are actually managed using an
ecosystem approach versus single-species stock assessment models? I know
there's debate over whether the Bering Sea fisheries could become that
way.
The comprehensive research done there feeds into their regional fishery
council's decisions, but I don't think it's truly an ecosystem-based
approach in terms of analyzing how many of say Pollock are needed not
just
to feed people but also to feed the fur seals, the seabirds, etc to
prevent
ecosystem collapse.
But my question is not about the Bering Sea but about whether there is
ANY
fishery that is actually managed in an ecosystem approach or whether
it's
still theoretical at this stage?
