An evaluation of methods for determining movement of shrimp. final report, July 1, 1970 to June 30 1971 / Phase I, Shrimp movement studies

The management policy of the Fish Commission of Oregon concerning the Pacific pink shrimp, (Pandalus jordani) has resulted in regulations which apply to all shrimp along the Oregon coast and do not recognize separate populations. There are several shrimp grounds along the 300-mile length of the continental shelf off Oregon which may support distinct populations of shrimp. Until recently, it was believed that the shrimp fleet has been underharvesting the resource on these grounds. However, in the last few years the fleet and the intensity of the fishery has increased and concern has arisen that certain areas are being over-exploited. At present, we do not have enough information to determine if certain areas are inhabited by discrete populations of shrimp. (From the Introduction, p.1
