This year our small garden pond is totally blanketed with duck weed. Is
there a remedy likely to be harmless to the inhabitants? Netting it out
seems to stimulate further growth!

For an environmentally acceptable solution for larger ponds is the Grass
Carp Ctenopharyngodon idella which is a herbivore that feeds on plants and
algae (ordinary carp Cyprinus carpio will eat other pondlife).
