Species selected (Ptilosarcus gurneyi)

Aquarium Needs: large sand/Mud bed (species full grown average 2 feet, collect specimens 1' or smaller)
Species needs constant water flow (filter feeder, planktonic food supply needed)
Sump system for water circulation possible breeding ground for Plankton (copepods? Tigriopus californicus)

  • Sump
  • Aquarium
  • pump
  • overflow box
  • intake circulation powerheads/circulation pump
  • growth lights for sump and aquarium (add sand to sump as well as local marco algae for copepods)
  • mechanical filtration?
Decide to house in Roberts controlled Temp room or possibly talk with Greg about housing it in the Aquarium room so I could connect in to his system which likely already has a large supply of planktonic food available circulating in the system. 

Species collection Locations Bainbridge island, Whidbey island, Alki (spoke with LFS in the area no one knew of any good locataions but Greg has said that Bainbridge was a good location to find plus read ( ) an article stating that they are often found "behind whidbey island"
Got in contact with Jon Wittouck <> to put together
 everything needed for aquarium setup

Update: Jon replied and told me we should not have any 
trouble getting everything set up raised a good question
 to check "biomass of plankton filtered out of water per day" to establish feeding needs

Species creates luminescent mucous?
Species needs large sandbed or lower stalk can becomen inflamed. sent requesting information on Sea pen needs and possible diving sites.

Basic Aquarium handling and care 
Diurnal pattern of expansion
Culture of Rotifiers recommended or artifical plankton SDMP (ESV's spray-dried marine phytoplankont), APR (Artificial Plankton - Rotifer), or "Size I" (50-100µm), Cyclop EEze if grouded up to small bits.  Feeding on a regular basis

Check other types of plankton as better food supply
Online research shows mechanical filtration better for cold water systems since the cold temperature slows metabolic rates making it difficult to establish bacteria to properly cycle tank, and local live rock not porous enough to act as a good biological filter. (Check if tropical live rock/dead rock could be used as a replacement).live rock is a good habitat for copepods as well as macro algae (join aquarium blog to ask about cycling coldwater aquariums and types of filtration)

Ambient Flow on Volume Flow Rate and
Filtering Efficiency
Department of Zoology, Duke University, Durham, North Carolina 27706
Reference:Biol.Bull.175:332-342. (December, 1988)
Flow rate: 
Small optimum 5-6 cm/s data shows optimum efficiency at 1.5 cm/s
Mediuim/large 8-9 cm/s 
data shows optimum efficiency at 1.5 cm/s for both all sizes change from 1.5 to 6.0 decrease efficiency from 42.8-29.9%
optimum food particle size 10-25 microns

Height stats: sea pen with a rachis height of 7 cm, medium sea pen 15 cm high, and large sea pen 25 cm high
