Marine Worms Clean Up Shrimp Farm Effluent

 

Dr. Paul Palmer—a senior Queensland Government biologist with the Department of Agriculture, Fisheries and Forestry—and the Bribie Island Research Centre have received a $245,000 grant to continue their five-year project on the use of marine worms to clean up the effluent from shrimp farms.  Sand beds are stocked with a species of Moreton Bay sandworm, and the effluent from the shrimp ponds is flooded across the top of the beds.  The worms consume the nutrients and algae that get trapped in the sand beds.  The worms can also be harvested and used as a feed for shrimp broodstock.
