“…Research and monitoring efforts have, with the exception of deepwater habitat trawl surveys (Botton and Ropes 1987;Hata and Berkson 2003), focused on these annual spawning events when the crabs are most easily accessible (e.g., Rudloe 1980;Shuster and Botton 1985;Brockmann 1990;Botton et al 1994;Smith et al 2002b). Some studies have employed conventional tagging methods to study spawning behavior and migration patterns (Rudloe 1980;Brockmann 1990;Swan 2001). The study of inshore habitat use has been limited because it is difficult to observe horseshoe crabs in these habitats.…”

This study used telemetry to determine spawning behavior and subtidal habitat use of horseshoe crabs Limulus polyphemus. We attached combined acoustic and radio transmitters to 12 gravid female horseshoe crabs at Ted Harvey Beach and 12 at North Bowers Beach (both on the western shore of Delaware Bay) over a 5‐d period before peak spawning on the new moon. Horseshoe crabs were acoustically tracked and radio‐tracked daily for 8 d during both high tides and during the incoming dominant (higher) high tide. All horseshoe crabs were relocated at least once, and 83% of females spawned from two to six times (x = 3.35, SE = 0.18). Of these females, 85% spawned on two to five consecutive nights (x = 3.31, SE = 0.59). Most (95%) females spawned on the beaches where they were initially tagged. Typically, the shoreline used by an individual for spawning ranged from 70 to 1,160 m (x = 351 m, SE = 38 m). Between spawning events, horseshoe crabs remained 50–715 m offshore (x = 299 m, SE = 57 m) from their established spawning beaches. Following the new moon, all but one (96%) moved out of range of our survey area, which extended approximately 1 km from the shoreline. Multistate mark–recapture models were used to estimate recapture probabilities and daily probabilities of spawning and departure from the vicinity of the spawning beaches. The probability of recapture by acoustic telemetry was high and estimated to be 0.95 (95% confidence interval, 0.73–0.99). Horseshoe crabs equipped with acoustic and radio transmitters have high rates of recapture, can be tracked continually, and can be relocated in both foreshore and inshore habitats.

“…The substance limulus amoebocyte lysate can be extracted from horseshoe crab blood, which turns blue due to containing copper ions and can be used to test the presence of pathogenic toxins in the human body. Limulus amoebocyte lysate is in high demand and is also expensive, so it is called "blue gold" (Mikkelsen 1988, Prior 1990, Swan 2002). In the past, horseshoe crabs were a common seaside creature in Taiwan.…”

With the rapid decline in horseshoe crab population in Taiwan, the balance between economic development and conservation has become an important issue. Based on the random utility model of horseshoe crab conservation and economic development, we evaluated public support and willingness to pay (WTP) for horseshoe crab conservation and economic development. Our results showed that the public supported (1) horseshoe crab conservation and economic development together; (2) the inclusion of conservation concepts in elementary and middle school curricula materials and the training of conservation volunteers; (3) restoring the natural habitat of horseshoe crabs and listing them as a protected animal; and (4) issuing licensing requirements for horseshoe crab harvesting to allow the coexistence of conservation and economic development; moreover, we found that (5) female residents who have participated in conservation-related activities prioritize ecological conservation over economic development.

“…With the progress in scientific research, specifically, biomedical research (Shuster, 1962), researchers explored and revealed the visual, endocrine, and physiological processes of horseshoe crabs (Berkson and Shuster, 1999;Zaldívar-Rae et al, 2009;Carmichael and Brush, 2012). Horseshoe crabs have medical importance given that they produce reagents for testing bacterial endotoxins (Levin and Bang, 1964;Cooper et al, 1971;Novitsky, 1984;Berkson and Shuster, 1999;Swan, 2002;Kreamer and Michels, 2009) and vaccines (Maloney et al, 2018). In the marine ecological community, horseshoe crabs form prey-predator relationships with many animals and play a vital role in estuarine and coastal communities (Botton, 2009).…”

This review provides the updated information and analysis of research development on horseshoe crabs over the past 30 years and raises some suggestions for future studies on horseshoe crabs. Horseshoe crab is a unique marine species and attracts many scholars in various research fields. However, to date, the development of horseshoe crab research has not been analyzed and reported from a bibliometric perspective. Bibliometric analysis is a unique tool for evaluating the development of a specific research area by analyzing relevant publications and researchers from all over the world. In this study, Web of Science, Google Scholar, and PubMed were used to collect relevant data on horseshoe crabs. VOSviewer software was used to visualize cooperation and major keywords in horseshoe crab research. From 1989 to 2019, scholars emphasized the physiological characteristics, medical value, and ecological conservation of horseshoe crabs. Some topics in this field have gradually developed because of some reasons explained in this review. Some important or recent studies have been discussed, and some potential research topics for future research have been suggested.
