California Spiny Lobster Fishery Management Plan
The California Spiny Lobster is an important natural resource managed by the state of California for over 100 years. The species supports a valuable commercial fishery and a significant recreational fishery. The California Department of Fish and Wildlife (CDFW) has drafted a Lobster Fishery Management Plan (FMP) to guide future management of the fishery as required by the Marine Life Management Act (MLMA).
The MLMA identifies external scientific review as a key tool to ensure management decisions are based on the best available scientific information. It is crucial that management decisions be based upon a foundation of the best available science, and therefore CDFW has asked the California Ocean Science Trust (OST) to coordinate an external scientific and technical review of the harvest control rule threshold reference points prescribed in the draft Lobster FMP and supporting materials. The peer review process has been extended until mid to late May.
Harvest control rules are plans of action that prescribe adjustments in harvest regulations (e.g. fishing effort, allowable catch, minimum legal size) and are activated (“triggered”) when a defined catch or biological limit, also known as a threshold reference point, is reached. CDFW is seeking an independent assessment of whether the technical components and supporting documents that underpin the proposed threshold reference points prescribed in the draft Lobster FMP are scientifically sound and reasonable given CDFW's currently available data streams and analysis techniques. Read additional information about the review process of the Lobster FMP.
Science Review of the FMP is Complete
CDFW would like to thank the Ocean Science Trust and the science review panel for their thoughtful review of the FMP and synthesizing review comments into a concise final report. The report is available on the Ocean Science Trust web page: Review of the California Spiny Lobster Fishery Management Plan.
The Draft California Spiny Lobster Fishery Management Plan uses the Cable model to calculate spawning potential ratio (SPR), one of the three threshold reference points prescribed by the harvest control rule. CDFW provided a presentation and report to the science review panel in March describing the structure, parameters, and the principal mathematical relationships in the model. Additional model analyses were requested by the panel and provided by CDFW during the review process.
The following documents were provided to the science review panel in March 2015:
- Lobster FMP Science and Technical Presentation: Cable Model for Calculation of a SPR Biological Reference Point
- Draft Report on the Cable-CDFW 1.0 Model and the Calculation of Spawning Potential Ratio
- Cable-CDFW Model Sensitivity Analyses
Based on recommendations in the Review of the California Spiny Lobster Fishery Management Plan, revisions to the draft FMP, the Cable-CDFW model, and the Cable-CDFW report are currently in progress.
The Lobster FMP is scheduled to be introduced to the Fish and Game Commission at its December 9-10, 2015 meeting. At that time, the formal public review process will begin and public comment on the Lobster FMP will be sought.
