A Florida Stone Crab's Life Cycle

Stone crabs are one of Florida’s most valuable fisheries, and like other species we depend on for seafood, they often utilize a variety of habitats and undergo a series of physical transformations throughout their life.

Mating in stone crabs takes place near and offshore during the fall and can only occur when the female has molted and her shell is soft. While eggs are fertilized internally, they are eventually deposited beneath the female’s abdomen or “apron” in an external mass called a sponge. Spawning typically occurs during summer months and females can release millions of fertilized eggs in several intervals.

The eggs, which float in the water column, usually hatch within two weeks and then larval development takes approximately a month to complete. Larvae are planktonic and are transported to coastal and estuarine waters. The first larval stage to emerge from the egg is a called a zoea. As the zoea larvae grows they pass through five distinct changes before developing into a post-larval form called a megalopae. The megalopae, which is more crab-like in appearance, will settle to the bottom where it will take shelter. Here, it will molt several times before transitioning to a juvenile stone crab.

Unlike adult Florida stone crabs, which are tan in color, juvenile stone crabs up to about 2.5 cm (1 inch) in width are deep purple to black with white flecks on their carapace. Like the adults though, they have distinctive white bands on their legs. As they grow and molt, they will begin to take on the appearance of adult stone crabs. Juveniles can be found living among shell rubble, oyster beds, sponges, and tunicates in estuarine and nearshore habitats.

Florida stone crabs becomes sexually mature by two years of age. Adults will move around and can be found living in burrows among seagrass communities, or offshore out to depths of 200 feet, where they live under ledges or in burrows and crevices associated with hardbottom communities. Age estimates suggest male Florida stone crabs live for seven or eight years while females can live up to eight or nine years.

 

Overview of Florida's Commercial Snapper Fisheries

Snappers (Family Lutjanidae) are a widely-distributed group of fishes that inhabit a diverse range of coastal and marine habitats. They are generalized predators characterized by the presence of strong jaws with prominent canine teeth. Generally smaller than grouper, they can range from a few pounds to over 60 pounds. Florida has approximately 15 snapper species; only half of which are targeted by commercial fishermen as they are prized for their firm texture and mild flavored meat.

 

Landings

by FloridaCoast: Source:FWRI

Over the last decade, an average of 4.3 million pounds of snapper worth an average of $10.7 million were landed by Florida commercial fishermen. Despite the diversity of snappers found in Florida waters, approximately 90% of commercial landings come from three primary species; yellowtail, vermillion, and red snapper. Top landings for red and vermillion snapper occur in the Panhandle region, while south Florida dominates yellowtail landings. Much like grouper, the overwhelming majority of snapper are landed on Florida's Gulf coast in federal waters.

Management
Snappers are heavily regulated with high demand from both the commercial and recreational sectors. Stocks are managed separately in the Gulf and Atlantic waters. State regulations typically mirror federal rules for consistency, but this is not always true. Management of the snapper fishery has been challenging due to a lack of data on both the resource and the fishery. Improved data collection during the 1980s and 1990s has provided more management information on some of the more commercially and recreationally valuable species, but lack of basic management data on many of the species still remains the major obstacle to successful management.

Status of Populations
Of Florida's three major commercial snapper species, yellowtail populations appear to be the most robust. They are neither overfished nor experiencing overfishing in either the Atlantic or Gulf of Mexico. While vermilion snapper are abundant in the Gulf of Mexico, population levels are lower in the Caribbean and South Atlantic. They are not considered overfished, but are experiencing overfishing in this region; management measures are currently in place to end overfishing.

Perhaps no other snapper species has generated as much controversy surrounding its management than red snapper. Because of its high demand by both commercial and recreational fishermen, it has undergone intense fishing pressure for years and is one of the most tightly regulated fisheries in the United States. South Atlantic stocks of red snapper are overfished and experiencing overfishing. The decline in the Atlantic population is thought to have occurred since the 1950s with continued pressure in following decades. The 2008 stock assessment indicated that overfishing was occurring at 14 times the sustainable level. Based on this information, the entire snapper fishery was shut down in the beginning of 2010. Recent considerations to shut down large areas off of Florida and Georgia’s coasts to all snapper and grouper fishing was negated due to updated stock assessment data that indicated the stock was in slightly better shape than previously thought. It is expected, however, that the fishery will remain closed for several more years and a full recovery won’t be for several decades.

Since implementing a catch share program in 2007 the commercial Gulf red snapper fishery has seen a 40 percent increase in the total allowable catch. In fact, overfishing of red snapper in the Gulf ended in 2009. While still classified as overfished, the stock appears to be rebuilding faster than anticipated; even with the better than expected news, the stock is not expected to be fully recovered until 2032.

Several factors have contributed to the complexity associated with red snapper management:

Shrimp Trawl Bycatch
Historically, the unintended bycatch of juvenile red snapper in shrimp trawls contributed to a significant portion of snapper mortality. Over the past several years though, the domestic shrimp fleet has been significantly reduced due to fuel prices, competition with imports, and hurricanes. As a result, juvenile mortality levels have decreased, contributing to faster than expected rebuilding efforts. In addition, improved designs in Bycatch Reduction Devices (BRDs) in shrimp nets is thought to have contributed to recovery efforts.
Discard Mortality
Because of strict regulations such as closed seasons and size and bag limits, many red snapper are released by fishermen. Unfortunately, a significant percentage of these released fish (approximately 40% of released recreational fish and up to 90% of released commercial fish) do not survive, which further hinders management efforts to rebuild the fishery. Recent regulations requiring the use of circle hooks, dehooking devices, and venting tool have helped to reduce release mortality of released fish.
Management Mandates
In 2006 the Magnuson-Stevens Conservation and Management Act set new guidelines to end overfishing and rebuild U.S. fish stocks. The re-authorization directed managers to act quickly to implement regulations to reduce mortality and end overfishing of affected stocks. As a result, managers were forced to implement more stern actions to rebuild red snapper stocks. Public Perception
Despite red snapper populations being considered overfished, many fishermen report catching more than ever before. Part of the issue has to do with the life history of red snapper. Red snapper are thought to live at least 50 years, and larger fish do not always mean older fish. Despite recent increases in overall numbers of red snapper, the age structure of the population remains truncated and there are not enough older fish to successfully repopulate the stock. Adding to the frustration of fishermen is that the ongoing snapper regulations have occurred during tough economic times, thus affecting their ability to earn a living from snapper fishing.

Snapshot of marine economic impacts in and around Collier County

Economic impacts measure the level of economic activity in a given area. They may be viewed in terms of: (1) business output (or sales volume), (2) value added (or gross regional or domestic product), (3) business taxes, (4) personal income (including wages) or (5) jobs. Any of these measures can be an indicator of economic well-being (source: Economic Development Research Group, 1997). Below is a snapshot of the marine recreational and commercial industries and activities in Collier County (and surrounding areas) and their economic consequences and impacts.

Recreational Saltwater Fishing Activities

• In 2010, 26,275 recreational saltwater fishing licenses were purchased in Collier County resulting in over $ 4.7 million dollars in sales. In addition over 2,000 special endorsements such as snook and lobster permits and tarpon tags were purchased with an estimated value of  over $21,300.  (source: Florida Fish and Wildlife Conservation Commission – FWC).
• Charter captains in Collier County purchased 221 fishing licenses for either the captain or vessel in groups of 4 or less, 6 or less, 10 or less or 11 or more passengers resulting in over $60,130 in sales (source: FWC).
•  Fishermen and divers who use southwest Florida’s artificial reefs sites spend over $253 million in the region annually. (source: Florida Sea Grant)
• Expenditures on artificial reef-related activities in Southwest Florida generated almost $227million in economic outputs that supported over 2,500 full- and parttime jobs.
• In southwest Florida (Manatee, Sarasota, Charlotte, Desoto, Lee and Collier counties) recreational fishing activities resulted in $1.3 billion in sales and supported 14,530 jobs in 2007 (source: FWC and NOAA Marine Fisheries)  
•  In the 2010/2011 fiscal year, over 1.2 million individuals bought a saltwater recreational fishing license including more than 860,000 Florida residents and 394,000 non-residents. Total revenue for all marine recreational fishing license sales was over $25 million. (source:FWC)
• Recreational fishing resulted in over $5 billion in economic impacts and supported approximately 50,000 jobs during 2009 (source: FWC).

Commercial  Fishing Activities

• 171 commercial fishermen held saltwater products licenses in Collier County during 2008/09. There were 20 wholesale dealers, and 93 retail dealers over the same period (source: FWC).
• Over 1.5 million pounds of  seafood products were landed by commercial fishermen in  Collier County in 2010. Of this amount, 608,000 pounds were stone crab claws worth an estimated $5.5 million in dockside value (source: FWC)
• San Carlos Island shrimp harvesting and processing resulted in $54.9 million in economic impact for Lee County and supported 1,555 jobs in 1998 (source: Florida Sea Grant).
• In Florida commercial fishing and seafood production resulted in $12.9 billion in sales and support-ed 64,744 jobs during 2009 (source: NOAA Fisheries of the US).

 

Boating Activities
