An introductory workshop of Juvenile Horseshoe Crab Rearing Programme was held on 16th October 2021 at City University of Hong Kong. Twenty secondary schools joined the rearing programme this year. The information and importance of conservation of horseshoe crab were introduced to the participants. Our school was selected as one of the participant representatives to share the prior horseshoe crab rearing experience to the newly joined schools. Young horseshoe crabs will be distributed to participating schools in December 2021.
