Closed Systems for Polychaete Production


Francisco Javier Tobías Jiménez ( reports: Wild polychaetes (marine worms) are used in shrimp hatcheries to supply broodstock with HUFAs (highly unsaturated fatty acids) that increase the quality of shrimp eggs and embryos.  Wild polychaetes, however, pose a disease threat and are not always of a consistent quality.  The best option is to have polychaete rearing systems integrated into your broodstock production facility.


In Spain, for 20 years, I have worked on the development of closed systems to farm the marine worm Lumbrineris impatiens (Atlantic and Mediterranean populations), and more recently I have worked on Marphysa sanguinea from South Korea, growing both species at very high densities.


My team can supply consulting services to help you develop your own in-house, polychaete-rearing system with local or exotic worm species.  We provide project assessment, designs, information on funding and help with your research activities.  Some parts of your program would be developed at our laboratory in Spain and managed remotely from Spain in a continuous process of information exchange.
