Culturing polychaetes w/out fresh, unfiltered seawater

Tue Jun 29 13:08:18 EST 1999

I've not tried to keep Pectinaria happy in the lab, but for spionids 
and other deposit feeders I've found that mixing finely ground 
tetramin flakes with sediment will suffice as food.  Another 
alternative is flake baby food (a mixed cereal) mixed with sediment. 
Pectinaria is a head-down deposit feeder, so you don't want to leave 
all the food stranded on the surface.  I recommend using either type 
of commmercial food sparingly.  If your facilities allow, culturing 
microalgae or diatoms and mixing them with sediment would probably be 
best.  Bob Whitlach published a paper in 1974 on food-resource 
partitioning in Pectinaria (Biol. Bull 147(1):227-235 ) which might 
be useful.  

Good Luck,
