Stabilizing South Carolina’s Blue Crab Fishery Brad E. Floyd South Carolina Department of Natural Resources Office of Fisheries Management February 4th, 2019 1 Problem Statement The mission of the Department of Natural Resources is to be the principle advocate for and steward of South Carolina’s natural resources. Within DNR, I work for the Office of Fisheries Management (OFM) which deals with all aspects of commercial and recreational marine fishing in South Carolina. OFM staff make recommendations to the general assembly for changes to existing laws or proposed new laws that govern the marine resources of South Carolina. OFM staff also serve on various committees and counsels that work across state lines to manage fisheries on a regional scale. Laws governing the blue crab fishery in South Carolina fail to put limits on harvest or participation in both the commercial and recreational components of the fishery. It has been a goal for many years at OFM to propose legislation to bring our fishery laws in line with those governing the fishery in other states. It's believed that overall abundance of blue crabs is declining while the price continues to rise. This creates a potential management issue since there are no limits on effort, catch, or participation in the commercial fishery, and similar problems exist with the recreational component of the fishery. Current and former fisheries managers for OFM would like to see legislative changes to fishery laws that limit recreational harvest to a daily limit and cap the number of commercial licenses sold each year. Data Collection The first step was to characterize the blue crab fishery by analyzing the landings and licensing data. Also, an experienced commercial blue crab fisherman and fisheries managers were interviewed to obtain their observations and insights. Once all the information is summarized, analyzed, and reviewed, recommendations will be made to senior level fisheries managers to develop legislative proposals that would begin to limit the fishery. 2 To assess how South Carolina’s blue crab laws compare with other neighboring states, a summary of state laws in the Southeast region was compiled. This task was easier said than done, however. The laws for small states like Georgia and South Carolina were straightforward and easy to summarize in a concise table. The bigger the state, the more complicated the laws become. For states of North Carolina and Virginia, the laws were condensed to a broad overview and complied in a concise table along with South Carolina and Georgia (Table 1). Florida’s blue crab laws were complex, varied by region, and are included in the appendix section (Appendix A). Commercial blue crab landings data for the past ten years (2007-2017) were obtained in an excel spreadsheet from the statistics section of the SCDNR’s OFM. These data included: number of commercial fisherman and vessels contributing to the harvest, number of trips by vessel, pounds of blue crab landed each year and the vessel value of those landings. Commercial licensing data of blue crab fishermen in 2017 was also obtained from the OFM statistics section. These data included numbers of crab traps sold and the number assigned to each fisherman’s license. OFM statistics section also provided demographic information on blue crab fishermen including: age, county of residence, out-of-state participation and years of activity in the fishery. Information on opinions and participation of recreational blue crab fishermen was obtained from previously conducted surveys of recreational anglers. These surveys were conducted over several years by Responsive Management, a survey research firm specializing in natural resource, hunting and fishing, and outdoor recreation issues. Data Analysis & Results Commercial & Recreational Blue Crab Laws 3 Commercial blue crab laws in the Southeast region had some similarities and some stark differences (Table 1). The similarities existed in the licenses required, fees for traps and reporting requirements. South Carolina differed from others by having no seasonal closures or limits on the number of traps that a crabber can license at one time. South Carolina also had no specific area restrictions, but this is likely due to the size of the state and little regional variations in fishery conditions and practices. Recreational blue crab laws lacked a daily limit which most other states have and the number of crab traps that could be fish at one time by a recreational crabber was significantly lower than other states in the region. One implication that the commercial fisherman and fisheries managers interviewed for this project discussed was that it is perceived that some recreational fishermen wanting to fish more than two traps a day will become licensed as a commercial crabber. This will allow them to fish more than two traps a day but they will not have to report catch because it is not being sold. This results in “phantom” commercial crabbers, those that buy licenses but never have landings reported to OFM statistics section. Table 1.

This is to be expected as the population of coastal South Carolina and the demand for seafood products increases. Figure 1.

The vessel trips per year varies from around 11k to a high of 16k for the ten year period, and also shows a trend of increasing effort overall (Figure 3). 5 Figure 2.

Effort and catch do not always correlate in fisheries, especially short lived species like blue crab. Weather and spawning success each year has a great impact on the availability of the resource. Increasing effort doesn’t always mean more product landed each year. 6 Figure 4.

Although, the pounds of crabs landed has fluctuated yearly the amount of money being earned by the fishermen for their catch has been steadily increasing though out the ten year period (Figure 5).

Although the trend is increasing, overall the number seems to be holding steady between 30k and 35k a year. Although crabbers have no limit on the number of traps they can license each year, the number seems to not be increasing correspondingly to the increase in participation in the commercial blue crab fishery.
