Summary

Delaware Bay horseshoe crabs are thriving, with a population larger than in the 1950s.
Key points:
• Horseshoe crabs can live up to 20 years, mature in 10 years, and have no significant fossil record.
• The Delaware Bay population survived the loss of over 1 million crabs per year for 70 years.
• The population increased to over 1 million spawning crabs in 1990, after the fertilizer industry closed in 1970.
• Despite a 50% drop in 1992, the population has been relatively stable since then.
• Regulations, including a sanctuary and harvest caps, aim to protect migratory shorebirds, not horseshoe crabs.
• Weather controls horseshoe crab spawning, affecting bird success during stopovers.
• No further management regulation changes are needed, allowing nature to resolve the local migratory bird issue.
