| Popis: | Fishing for Pacific Hake Merluccius productus in the Gulf of California is carried out by shrimp trawlers. When the shrimp fishing season ends, these boats shift to catching Pacific Hake and other finfish. The Pacific Hake fishery is relatively new and has the potential to grow as an industry. Therefore, there is interest in defining management plans to create a sustainable fishery. One option is an individual vessel quota system. This paper estimates the per-vessel quota in the Pacific Hake fishery that achieves a break-even operation and estimates the number of vessels that could enter the fishery to avoid overexploitation and overcapacity. Potential per-vessel quotas were estimated based on the cash flow of a representative trawler and the estimate of total Pacific Hake biomass. The results indicate that individual catch quotas for Pacific Hake should be 90.4 or 100 metric tons to achieve a 30% or 45% increase, respectively, in net cash. Additionally, with total allowable catch values equivalen... |
