1 American Horseshoe Crabs in the Subtropics: Genetics, Phenotype, Populations, and Marine-Life Harvest H. JANE BROCKMANN (University of Florida, Gainesville, FL) TIFFANY BLACK (Florida Fish and Wildlife Conservation Commission, Cedar Key, FL, USA) TIM L. KING (U.S. Geological Survey, Kearneysville, WV, USA) 16 June 2015 International Workshop on the Science and Conservation of Horseshoe Crabs Sasebo-City, Nagasaki, Japan 1
2 Most horseshoe crabs are found in the subtropics or tropics Subtropics Tropics Subtropics 2
3 Most research on horseshoe crabs is from temperate regions Temperate Subtropics Tropics Subtropics Comparison with Asian species requires an understanding of subtropical and tropical Limulus. 3
4 Subtropical and tropical Limulus are genetically different from temperate populations Subtropical Tropical (King et al. 2015) Neighbor-joining phenogram depicting genetic distances among 35 collections using 13 highly variable microsatellite markers (nuclear DNA) 4

6 Study Sites Cumberland Island (CUIS) Seahorse Key (SK) Gulf of Mexico 100 miles 161 Km New Smyrna Beach (NSB) Indian River Lagoon (IRL) 6
7 Florida has at least 5 genetically distinct populations of horseshoe crabs Based on neighboring joining trees using 13 highly variable microsatellites and analyses using STRUCTURE No migration between populations Boundaries between populations are not known (in progress) From King et al Numbers indicate collection sites 7

9 Population structure of northeast From King et al Florida horseshoe crabs Indian River Lagoon Numbers indicate collection sites Based on the distinctive phenotype of the Southeast Atlantic population, they extend to New Smyrna Beach Where they overlap with the Florida East population, which is in the northern Indian River Lagoon Populations overlap, do they interbreed?

Preliminary data from GA and SK compared with data from Cape Cod, MA (Carmichael et al. 2003): Similar rates of development despite very different adult sizes Suggests that molt number is variable, i.e. different numbers of molts in different populations They may molt more often (e.g. 2x/yr?) where they are active (feeding) all year 10
11 Horseshoe crabs are active throughout the year in GA and FL East (Atlantic) East (Atlantic) Coast Coast West (Gulf) Coast Jan Dec Jan Dec Data from FIM trawl surveys by GA DNR and FL FWCC Jan Dec 11
12 Dec Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Median Number of Sightings North-Gulf North-Atlantic South-Gulf South-Atlantic Seasonality Northern Sites: no spawning in Dec and Jan, heavy spring spawning and a smaller peak in autumn Southern Sites: Spawning throughout the year with no obvious peaks From on-line database with sightings from the public 12
13 Effect of Tidal Fluctuations on Spawning Seahorse Key (SK) Gulf of Mexico Cumberland Island (CUIS) New Smyrna Beach (NSB) Indian River Lagoon (IRL) Spring Tides: High tide height CUIS: 2.5m NSB: 1m IRL: 0 (microtidal) SK: 1.3m 13
14 Effect of Tides: More spawning when actual high tides are higher Seahorse Key, FL <95 mm >125 mm From Brockmann & Johnson
15 Spawning affected by water height Seahorse Key (SK) Cumberland Island (CUIS) New Smyrna Beach (NSB) All sites are strongly affected by tidal inundation and/or wind surge. Highest spawning densities are during spring high tides. Indian River Lagoon (IRL) 15
16 Ponce Inlet at New Smyrna Beach Status of Florida populations? Alligators eat horseshoe crabs Cars driving on the beach are a serious threat to nesting Limulus Horse conchs eat horseshoe crabs 16
17 Northern Gulf Coast Status of Florida Populations Atlantic Coast Southern Gulf coast Only data available are monthly Florida FIM trawl surveys where horseshoe crabs are bycatch (only a 17 few caught per 100 trawls)
18 Indian River power plant kills Limulus Horseshoe crabs follow currents into plant intake Florida Power and Light Canaveral Plant in Indian River protects turtles and manatees Horseshoe crabs trapped by one power plant in Feb-March 2015 were deposited in a landfill (many still alive) Two Indian River power plants trapped 173,662 HSC/year in ,218 HSC/year in 1979 No data since then 18
19 1992 Population Status at SK Breeding Survey Spring ǀ Seahorse Key long-term breeding beach survey. Mean number of pairs on 1 km beach during spring tides Population is not harvested Population is stable or increasing 19
20 Harvesting horseshoe crabs in Florida Biomedical none Bait for eel and whelk hand harvest only 25 hsc/person/day annual total for FL below 9,455 limit set by ASMFC Marine-life fishery hand harvest only 100/person/day no total annual limit harvesters report with trip tickets mostly juveniles Bait harvest is for the eel fishery 20
21 Horseshoe crabs are fun to watch Florida Aquarium, Tampa Marine-life harvest Horseshoe crabs are harvested for the home aquarium trade Some specimens are used for research and education Horseshoe Crabs: Sand Stirrer, Detritus Eater. The Horseshoe Crab can be a unique specimen for any aquarium Very hardy, a good choice for beginners. An excellent reef aquarium species because it will not bother invertebrates Level of Care: Easy Small: 2-4 (1-3 yrs) Medium: 5-7 $18.99 (4-6 yrs) 21
22 Number landed per year Marine-life harvest landings = 110,879 CPUE has declined CPUE remains strong From State of Florida, Marine Fisheries Information System 18,593 55,460 juveniles harvested annually in Florida Impact of juvenile removal Release sites 22
23 Conclusions: Limulus in the Subtropics Patterns Population structure: 5 genetically distinct populations Phenotypic differences between populations: large size variation Life history: possibly variable number of instars Seasonality: active all year; north: breeding spring & fall; south: breeding at any time Factors affecting spawning: tide height and wind surge Management Population structure: distinct populations may require different management strategies Population status: unknown in most areas; probably declining in Indian River, stable in the northern Gulf population (long-term surveys needed) What is the impact of the marine-life fishery that harvests mostly juveniles? Limits are needed; controls on release needed 23

26 The Southeast Atlantic population is phenotypically different from all others 40-60% have these extra spines Juvenile from Wassaw Sound, Georgia (near Savannah, GA) 26
27 Citizen Science efforts starting: New Smyrna Beach and Indian River Breeding Surveys Tagging studies to understand movements 27
28 Status at SK Despite variation in breeding numbers, the breeding sex ratio has remained at about 60% male. The proportion of males and females that are newly molted, i.e. adult recruitment varies markedly from year to year. 28
29 Developmental rates are similar SK 29
