A long abandoned driftnet with many horseshoe crabs trapped in it was seen at Kranji mudflats during a trip with the Bivalve Workshop.
It was Ivan who showed me the abandoned. Yen-ling came by to help us pull out the net and rescue the animals trapped in it. The driftnet is quite long, we pulled out about 50m of it. The rest seem to be laid across the stream and was too deep and embedded to pull out.
Mangrove horseshoe crabs (Carcinoscorpius rotundicauda) were trapped in the net. Many of them were still alive and we managed to rescue about 40 of them. Including the dead ones, I estimate there were about 80 animals trapped in the net. We had to work fast as the trip was ending so I couldn't take proper photos or keep count.
Stone crabs (Myomennipe hardwicki).
Malayan water monitor (Varanus salvator), but more likely a Banded file snake (Acrocordus granulatus). Sigh.
300 horseshoe crabs were found trapped in an abandoned net at Mandai. The Nature Society (Singapore) has a programme to track horseshoe crabs in another part of Kranji and does work on horseshoe crab populations in Singapore.
