520 |aCreel and index fishing data from ponds in Indian Bay, Newfoundland were used to construct a model for managing the exploitation of brook trout (Salvelinus fontinalis). The model describes the expected relationship between angling effort (angler-hr/ha) and brook trout yield (kg/ha). It predicts a maximum yield of approximately 0.4 kg/ha at a fishing effort of 3 angler-hrs/ha and extinction of the fish population at 8 angler-hrs/ha. Maintenance of a high quality fishery calls for regulations that restrict fishing effort or reduce its potential impact. A dynamic simulation model (calibrated for Indian Bay brook trout) was used to compare the effectiveness of various types of management regulations (e.g. creel limits, size-based restrictions on harvest). The simulation results indicate that creel limits will not prevent over-fishing and that size-based management is needed to offer a sustainable high quality fishery.
