Polyculture of Worms and Tigers

 

A Queensland Department of Agriculture and Fisheries (DAF) research project is demonstrating how shrimp (Penaeus monodon) and marine worms (polychaetes) can be grown in the same integrated system, leading to increased productivity and better waste management.

 

The two-year project, co-funded by the National Government’s Landcare Programme and DAF, is testing the concept of fully recirculating pond water from intensive shrimp ponds through sand filters stocked with polychaete to create sustainable supplies of shrimp and marine worms.

 

Agri-Science Queensland Senior Biologist Dr. Paul Palmer said, “The project has recently successfully produced its second crop of giant tiger shrimp and marine worms on a semi-commercial scale, without water discharge from the system.  ...Shrimp hatcheries use the marine worms as feed to improve the quality of their broodstock, and they are also finding particular favor in the live bait industry.  ...Presently, the shrimp farming industry uses settlement ponds to treat its wastewater, and this latest development offers improvements to this process.”
