| Summary: | Some fisheries management activities have clearer relationships
with angler consumption than others, end the clarity is
usually reflected by the amount of historieal data available
upon which to base the relationship. Adequate historical data
exists to derive the relationships between angler-days and
access development, water development, regulation changes, and
catchable trout stocking, so these relationships are probably
the most reliable in PISCES. Little historical data exists to
assess the effects of research and information and education
activities upon angler-days. Therefore, the segments of PISCES
accounting for research and information and education are
probably the least reliable parts of the model.
PISCES can be improved before it is utilized in decision
analysis. First, the efficiency of the computer program
could be improved. PISCES is functional, but computer time
and storage space might be saved by altering the program.
Second, sensitivity analysis of input variables would provide
important information to future users of PISCES. And finally,
an application study would reveal any unforeseen problems
which might arise in using PISCES.
If PISCES is never used to formulate management decision
policies, it is hoped that some of the modeling techniques
employed will prove useful in future efforts to model natural
resource systems. === Master of Science |
