A professional fisherman can find some use for all the fish he pulls out of the sea;
he cannot afford to be too particular.
The proverb advises us to follow his example by taking advantage
of everything that comes our way.
It’s similar to the proverb: “All’s grist that comes to the mill.”

This was taken in Sai Kung, Hong Kong.
The fishermen and women come alongside the pier with a variety of live fish,
shrimp and crabs in plastic, aerated boxes and people call down for what they want.
Money and catches of the day are exchanged in long-handled nets.
