Our tagging season is now closed for this year! We will begin recruiting for field assistants again beginning next summer. Each volunteer will spend a day helping recapture/tagging efforts. If you are interested in helping to collect and record data on local commercial lobster vessels, please send an email here.
The Lobster Monitoring Project brings together a diverse group of stakeholders to quantify baseline levels and short term changes in the abundance, size structure, habitat use, and movement of the California spiny lobster inside and outside of several local marine protected areas. The project is part of the South Coast MPA Baseline Program, a collaboration of California Sea Grant, California Ocean Protection Council, Department of Fish and Wildlife, and the MPA Monitoring Enterprise, a program of the California Ocean Science Trust.
The California spiny lobster, Panulirus interruptus, is a significant commercial and recreational fishery species in Southern California. As a network of marine protected areas (MPAs) went into effect throughout the south coast region in January 2012, it is important to understand how fishery closures in these areas affect the lobster’s ecology.
SDOF volunteers work collaboratively with researchers from San Diego State University and Scripps Institution of Oceanography, marine biologists from the California Department of Fish and Wildlife , and commercial lobster fishermen from the California Lobster and Trap Fisherman’s Association to tag and record data about lobster in Southern California. In addition to the tag/recapture program, SDOF volunteers will help researchers collect data on lobster density and shelter use, catalog important lobster habitats using seafloor mapping technology, and monitor how fishing effort and catch totals differ before and after the implementation of the marine protected areas.
What does a tagged lobster look like?
The tags for our project are approximately 2-inch yellow, blue, and green strips of plastic inserted into the underside or back of the lobster. Each tag has a unique tag number. The yellow and blue tags have our contact information printed on them “www.taggedlobster.com or 619.523.1903”, while the green tags do not. While most lobster will have only one tag, some lobster may have a tag on both the underside and back. For a lobster with two tags, please make sure to submit both tag numbers.
When a lobster is recaptured, its GPS coordinates, sex, reproductive state, and size are recorded so researchers can learn how the lobster travels in and out of the MPAs (spillover), its growth rate, and other relevant information.
I’ve found a lobster with a yellow, blue, or green tag attached to it. What should I do?
If a lobster is caught and it has one of our yellow, blue, or green tags on it, please submit the following information to www.taggedlobster.com (submit information using the form above) or call the SDOF office at 619.523.1903:
- Tag number
- Location where the lobster was caught (GPS coordinates are best, but distance to a recognized landmark is accepted as well)
- Carapace length of the lobster (to the nearest millimeter if possible)
- Date the lobster was found
If a short lobster (under legal size) is caught and it has a tag attached to it, it may be brought to the surface to be measured. Once the tag number has been quickly recorded, the lobster must be released immediately. No undersize lobster, even if it is tagged, may be brought aboard a boat, placed in any type of receiver, or retained in any manner. Please do not remove any tags from any short lobster. You must comply with all Department of Fish and Wildlife regulations.
Why should I participate?
- We need your help! By submitting the location and tag number of each tagged lobster you find, you are providing us with valuable data that can help us learn more about this important species.
- Win great prizes! Each tag submitted earns you a ticket in our monthly raffle. Prizes include hundreds of dollars in restaurant gift cards, SeaWorld tickets, and so much more!
- Be a part of the future of the California spiny lobster! The data collected will inform the California spiny lobster Fisheries Management Plan (FMP) by providing important information on abundance, size distribution, behavior, and consumptive use of the lobster inside and outside of several local MPAs.
- Receive up to date California spiny lobster data! SDOF plans to share pertinent project data with program participants as soon as it becomes available.
In what areas are lobster tagged?
- Point Vicente State Marine Conservation Area off Palos Verdes
- Laguna Beach State Marine Reserve off Laguna Beach
- Swami’s State Marine Conservation Area off Encinitas
- South La Jolla State Marine Reserve off La Jolla
- Cabrillo State Marine Reserve off Point Loma
- September 2011: Approximately 5,000 lobster tagged off the coasts of Laguna Beach, Point Loma, and South La Jolla in zones slated to become MPAs in January 2012.
- April 2012: Research effort expanded. Approximately 20,000 lobster tagged. Data collection begins in Point Vicente SMCA off Palos Verdes, Laguna Beach SMR off Laguna Beach, Swami’s SMCA off Encinitas, South La Jolla SMR off La Jolla, and Cabrillo SMR off Point Loma.
- April 2012- September 2012: Researchers conducted dive surveys of Swami’s, South La Jolla, Cabrillo, and Laguna Beach to collect data on lobster density and shelter use. Researchers also used seafloor mapping technology to catalog important lobster habitat in South La Jolla and Point Loma.
