Citizen science frontiers horseshoe crab population regain at their spawning beach in East Peninsular Malaysia.

摘要: Abstract Carcinoscorpius rotundicauda and Tachypleus gigas may co-exist share common spawning grounds elsewhere but at Balok (East Coast of Peninsular Malaysia), C. is an understudied species. Neglected as research candidate because inaccessible grounds, smaller size less commercial value than T. also, difficulty to attain from the wild has made population status remaining unidentified Balok. This standpoint drove present attempt anthropic activities like structure placement mining are point-source for runoffs that load sediments into River. While erosion-accretion events have altered River width, shore in Beach were transitioned between medium-fine fine sand years 2012 2016. Eventually by year 2016, depositing 5117 eggs 91 nests 200 1000 m range along this corridor facing South China Sea. From yield, released 2880 56 during Southwest monsoon, 1254 19 Northeast monsoon 983 16 Inter-monsoon seasons. Though female opted lay their shallow burrows lower shorelines, absence erosion substantial silt clay (>20%) deposition facilitates embryogenesis with brief periods temperature salinity shocks day-time falling tides. encourages emerge increasing abundance carry out bi-monthly Beach. In short, restoration initiatives systematic boat docking, proper disposal nets waste and, periodic fish-catching operations effectively led fisher citizen scientist. successful community joint-cooperation proves citizen-led caretaking degraded beaches offers marine life protection practical coastal area management especially areas where other oviparous animals such turtles crocodiles harboured.
