Temperate eco-sphere? Yeah I did it....

Post by AquaticEngineer on December 28th 2011, 3:41 am

Well kinda......

I got bored today so I set up a little fish bowl I had laying around with some sand, a rock, and a bunch of algae and tigroprius californicus (tiger pods) that I collected over the summer and have been growing out since.

Tossed a couple other small unidentified intertidal shrimp in there and voila, temperate eco-sphere Very Happy

I know that the tigroprius will eat the decaying portions of the algae, the algae will uses photosynthesis to trap some of the waste in solid tissue, and I'm hoping that the shrimp will eat the tigrops and or algae at an acceptable rate. I know the algae and tigrops will be ok at room temp since they are from the splash zone, dont know how the larger shrimp will fair, but I guess we will find out Laughing

I wouldn't worry about the shrimps if they are Heptacarpus sitchensis or something similar: I've seen them in tidepools with temperatures in the mid 20's (C).

Pretty sure thats exactly what they are Smile Caught them in seagrass beds in a coastal bay. Most of them where green at the time, but have since molted and are mostly clear with some faint tiger striping. I'm hoping they color back up to the greens I caught them with now that they are in with some algae to match.

Sure thing Smile

Been up and going since the night of the 27th with no problems yet.

Is the idea that it wont require mechanical filtration?

Still running strong Smile Been up for about 2 months now.

I upgraded the size to a bigger vase with a better viewing area and I also setup several more smaller ones to experiment with different types of algae.

I had a phyto plankton bloom in my main one and in stead of doing a water change, I placed a single small Blue Mussel in ther and it filtered it all out Very Happy I decided to keep it in there to see how it does and if it could be a good long term "filter" for the shrimps waste.

These are clickable thumbnails, so if you want to see it in greater detail just click the photo.

I have some ideas for a more complicated version of the temperate eco-sphere if you want, they're probably marketable too.

4PacNW wrote:Well, here is my idea for a larger version of one of these. It is based partly on the fact that there are often much smaller species with the same or that have shared ecological roles, e.x. Oligocottus maculosus or synderi are almost structually identical to other larger sculpins, Leptasterias hexactis consumes mussels and barnacles amongst other things, as does Pisaster ochraceus. The second basis for this idea is that some species have very broad diets, an example being Fusitriton oregonensis which feeds on ascidians, urchins, bivalves, sea stars, brittle stars, chitons, abalones, and polychaetes. Thus they should be able to survive with smaller amounts of each prey available and enabling a greater diversity of organisms to be possible.

These are most of the species I had in mind for this:

Algae: Laminaria bongardiana, porphyra spp, cystoseira geminata.

Fish: Oligocottus snyderi, Anoplarchus insignis.

Mollusca: Snails: Fusitriton oregonensis, nucella ostrina, Chlorostoma funebralis, Haliotis kamtschatkana, Amphissa columbiana, Margarites pupillus, Trichotropis cancellata . Bivalves: Mytilus trossulus. Limpets: Tectura scutum, Nudibranchs: Hermissenda crassicornis, Aeolidia papillosa, Diaulula sandiegensis, Chitons: Mopalia muscosa, tonicella lineata.

Echinoderma: Strongylocentrotus droebachiensis, Leptsterias hexactis, Amphipholis pugetana, Eupentacta quinquesemita, Parastichopus californicus.

Cnidaria: Anthopleura elegantissima.

Arthropoda: Cirolana harfordi, Idotea wosnesenskii, Mysids, Paracrangon echinata,Lebbeus catalepsis, Heptacarpus brevirostris, Heptacarpus sitchensis, Spirontocaris prionota, Cancer oregonensis, Lophopanopeus bellus, , Pugettia richii, Petrolisthes eriomerus, Phyllolithodes papillosus, Pagurus beringanus, Paguristes ulreyi.

Tunicates: Styela gibbsii, Boltenia villoa. Diplosoma listerianum,

Hydroids: Obelia sp.

Sponges: Neoesperiopsis rigida, Halichondria panacea.

Worms: Halosydna brevisetosa, Nereis vexillosa, Serpula columbiana, Eudistylia vancouveri, Eudistylia insignis.

Bryozoa: Bugula californica.

These are found in rocky intertidal - shallow subtidal outercoast semi exposed habitat i.e. with moderate current.

The largest species here is Fusitriton oregonensis with reaches a maximum length of 6" but matures at just over 3". The aquarium size required for this is unclear, my guess is about a 110 gallon with good current, it depends partly of the number of individuals required to maintain a population which is unclear, perhaps at least 8. Strong lighting is important for this obviously since there is no direct food imput. The maximum temperature for this is that of the urchin, Strongylocentrotus droebachiensis, which is the most northern species, which is supposed to be 20 C. I would try for 15 C. Basically everything here has a predator to keep it in check, except adult Fusitriton and crabs however their varied diets should prevent them concentrating on and thus depleting any one species.

This is a great idea. What type of crab would you think of placing in the tank? It'd have to be a species that isn't relatively aggressive but is also relatively small. Otherwise they might reproduce and over run the tank in the absence of a larger predatory fish. I'd look forward to your progress on such a project.

My bad. Do you have any idea of when you would begin such a project?
