Spawning season of goby

We started samplings of amphidromous gobies in March 2021.

Since the larvae usually hatch in the evening just after getting dark, we set a plankton net in the evening to collect the drifting larvae. The larvae will drift downstream to the sea, where they grow up until they return to freshwater streams and metamorphose to juveniles. Please don’t be surprised if you see us having an evening picnic on the streamside with tuna sashimi and potato chips. We are just waiting for larvae to start drifting. Our evening picnics will continue until May 2021.
