Abstract

The population decline in horseshoe crabs was increasingly revealed by various researchers in Asian countries, but there are still gaps in information regarding their population and ecological status. In data-poor situations, especially in the Banyuasin peninsula, collecting local knowledge was required because this approach was an easy, wide-scale, inexpensive, and rapid way to obtain data. This work aimed to assess the contributing local knowledge regarding the horseshoe crab's distribution, use, and threats to the existence of horseshoe crabs in the Banyuasin peninsula. Interviews using a questionnaire were conducted in five villages and one hamlet by visiting randomly selected households. The result revealed that most respondents (94%; n = 115) could correctly identify the species and shape between Carcinoscorpius rotundicauda and Tachypleus spp. Most respondents stated easily recognized C. rotundicauda by their rounded telson and smooth (without spines) whereas Tachypleus spp. was also easily recognized by their triangular telson with spines. The respondents avowed that Sembilang National Park Waters, especially Sembilang River (80%; n = 98), Cabe Island (71%; n = 87), Benawang River (56%; n = 68), and Sapi Island (52%; n = 64) were the most widespread location of horseshoe crabs. The C. rotundicauda was discovered more frequently than Tachypleus spp. in almost every distributing location around December (80%; n = 97), November (70%; n = 86), and October (57%; n = 69). The most horseshoe crabs benefit was for food (63%, n = 73). The main factors encouraged a decline in the horseshoe crab population, i.e. entangled in fishing nets (92%, n = 106). Respondents acknowledged that the Indonesian Government established the horseshoe crab as a protected animal. Fishermen's consciousness to reduce the horseshoe crab's bycatch and ensure it returned to the sea alive and safe was much needed to address the serious threat to its population decline.
