Murawski, S.A. and J.T. Finn (1986). "Optimal Effort Allocation Among
Competing Mixed-Species Fisheries, Subject to Fishing Mortality
Constraints." Can. J. Fish. Aquat. Sci., 43:90-100.
A linear programming (LP) approach to effort allocation among two or
more fisheries (fleets) exploiting several common species/stocks is described
and applied to otter trawl fisheries exploiting demersal fish stocks on
Georges Bank (northeastern United States). Total instantaneous fishing
mortality on a particular species (i) is computed as the linear summation of
fishing mortalities generated by each fishery (j):
F i =£q ij f i
i
where f i is the amount of standardized fishing effort exerted in fishery j and
q ij is the catchability coefficient for species i taken in fishery j.
Mortality on species i due to both directed fishing and bycatch can thus be
accounted for in the q ij 's. Optimal allocation of effort among the j
fisheries may be considered a minimization problem (minimize £f i ), subject to
the constraints that fishing mortality rates on particular species are
maintained at, above, or below certain predefined levels. Fishing mortality
goals for individual species can be based on various biological and/or
economic criteria: fishing mortality rates that prevent growth or recruitment
overfishing, or that optimize productivity from predator-prey systems. Other
constraints in the LP model may be included to modify optimal solutions based
on various economic and social considerations (e.g. protection of certain
fisheries). Sensitivity analyses indicate the general infeasibility of
maintaining relatively high or low fishing mortality rates on ubiquitously
distributed species, while moderately fishing species with more discrete
distributions, due to bycatch considerations.

Population Dynamics, Wiley-Interscience, New York, pp. 283-308.
There has always been considerable interest in the population dynamics
of the clupeoids, in part because of the size of the fisheries, but also
because their landings tend to fluctuate widely, and because some populations
have collapsed under exploitation. In some instances the collapse seems to be
relatively permanent. The six million tons of lost production detailed in
Table 35 may not be the end, as Peruvian anchovy catches fell to four million
tons in 1972, and did not significantly exceed two million tons in 1973.
Murphy, Thomas M. and Sally R. Hopkins-Murphy (1989). "Sea Turtle and
Shrimp Fishing Interactions: A Summary and Critique of Relevant
Information." Center for Marine Conservation.
This report examines the interactions between sea turtle populations and
the shrimp fleet, particularly from North Carolina to Florida, by analyzing
major aspects of each that relate to this interaction. The major aspects
examined are the density and distribution of marine turtle nesting, marine
turtle carcass strandings, incidental captures of marine turtles in shrimp
trawls, shrimping effort, and aerial observations of turtles at sea. Each
section on these major aspects looks at historic and current information,
values and uses for the information and shortcomings and cautions regarding
these data. The report also summarizes and critiques the primary source
documents upon which management and research decisions are made by the two
federal agencies that have legal jurisdiction over sea turtles.
