However, some marine mammals were caught and the incidental catch of turtles was larger than expected. Effects Evaluation Information is not sufficient to meet state-wide planning Goal 19. Blue sharks should be managed under the developing fisheries program with conservative numbers of permits and restrictions. Blue sharks are found world wide, a fishery off Oregon area will probably not have a big impact on the total stock. However, there is essentially no information, biological or stock, concerning blue sharks off Oregon.
Blue shark are moderately long-lived, slow growing, and have relatively low fecundity.
It is possible, a large part of the population off Oregon is immature females. Incidental catches in gill nets need to be determined. The effect on the ecosystem of a large-scale removal of a single species is unknown. There is no recreational fishery for blue shark. There are possible conflicts with pot gear and other fisheries.
