(probably panamensis).   Why culture pelagic copepods? Pelagic copepods are a mainstay in the diets of larval fish and invertebrates. They hold clear advantages over traditional early larval feeds (rotifers and brine shrimp nauplii) because they are much more nutritious. They also hold advantages over traditionally cultured benthic copepods because benthic copepods spend most, if not all, stages of their lives on or near some surface. Pelagic copepods spend all life stages suspended in the water column where each life stage is available to your larval fish.   Why culture Apocyclops sp.? Apocyclops seem to me to be a perfect copepod for the beginner to pelagic copepod culture. They are a good size (1st stage nauplii have been measured at 90 microns, far smaller than normal rotifers) and they are the easiest of the pelagics that I have tried. They have been successfully used to rear both shrimp and larval fish.   Mentoring Group Structure This mentoring group will be limited to around 15 participants. If you want or need to receive shipments from me then you must be located in the continental United States. (Sorry to those who don't live here, but international shipments of live animals are beyond me.) --Andy, the bucket man.

I'm willing to send you all starter cultures if you all will pay the costs of shipping and packaging.

You'll succeed so long as you try!!   Hoffs manual is pretty much the plankton "bible" much like Wittenriches book is the breeders "bible".  That said you are not bad off saying that you do not feel much more educated after reading it.  You are 100% correct in the practical experience peice.  Hoffs manual written sooo long ago is like a chilton for mechanics...  Reading for the sake of reading it a lot of times does no good, when you begin culturing you'll start to get it trust me!!   If you can, start up some rotifers as soon as possible, this will help you to get comfortable with the culture water changes and maintenance process.  it will help you to set up a good routine as well which is of the most importance when culturing.  Pelagically yours, ~J         #15 rgrking Total Posts : 712 Scores: 22 Reward points : 446 Joined: 4/8/2011 Location: Sullivan, MO, US Status: offline MBI: 305 Pnts MBI Site: Marine Aquarium Societies of North America Re:Class/mentoring group description Monday, July 25, 2011 10:19 PM (permalink) 0 I have rotifers and nanno that shipped out today.

You rock!   Like I say, these are good beginner critters. The O. marina is not much more difficult than rotifers and the Apocyclops is really forgiving except that (I always thought) they need a live food. Since I'm wrong about that last part, even better. --Andy, the bucket man.
