Abstract
The California Department of Fish and Game is presently considering a
request to the Secretary of Commerce to regain management authority of
the California sea lion because of mortalities and economic loss resulting
from interactions with coastal fishermen. Before the request can be
submitted various costs concerning State management have to be studied.
This thesis addresses the cost and effectiveness of five activities relating to the interaction between the shark drift-gill-net fishery in
Southern California and sea lions. The activities discussed are:
assessing population levels, assessing incidental take, limiting
the use of gill-nets by area and time of year, estimating the loss
of fish and gear due to depredation, and estimating the value of an
acoustical playback device. Where applicable, the cost and effectiveness
of different alternatives within an activity are compared
tc provide criteria for evaluation. Each activity is examined from
an economic perspective of what it might cost the state of California
or gill-net fishery if the activity were incorporated into an
overall management plan of California sea lions.
