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.
