I thought the FAO link was in here already, but even if its not, now all we need are those to be hyperlinks

The link at the top of his post takes you to the hyperlinked page. I love technology. No more paper cuts!!!

upside down bottles?

upside down bottles?

I have noticed in every phytoplankton culture I have ever seen the 2 liter bottles are always right side up... Is there merit to the idea of keeping the bottles upside down with air coming in through the bottlecap to prevent phytos or whatever from settling into the bottle? If the air is all the way at the bottom of the bottle (cap end, when upside down) it seems as though it would work.?? Any thoughts....

 

[rsman]

it works but not without problems,

if you feed air from the bottom then you have airline that will be exposed to algae, this is a bad thing, but an inverted 2l bottle with an air hole in 1 ?lobe? and an exit hole in the other works great. but then you have to keep it upright which can also be done.

 

[Atticus]

You have the right idea, but I believe you will create more problems than it is worth, as settling phyto really is not that big of an issue if you shake the bottles every once in awhile.

Bugger, you mean detritus not dirt. Hapacticoid do eat a lot of detritus, but the pelagic species don't. There are huge differences between the group. The reason why tanks normally have good population of hapacticoids is that they are benthic and almost never leave the substrate or they don't venture very far, and have benthic or semi-benthic nauplii. This on reason they are mostly worthless for culturing fish. The other is that they are nowhere near nutritious as most calanoids and cyclopoids.

I have a question on copepods. When I start raising rotifers again I think I will also try copepods, now is it possible to aclimate the copepods to a 1.014 salinity and breed them in my rotifer tank? Thanks

Hi all,

I am planning to start culturing phytoplankton and would like to know if there is a hardware store like lowes or home depot that sell the rigid tubing? Also, I read one of the article and it mentioned that the size for the rigid tubing is 1/8", is this correct?

Thanks

 

[rsman]

I wouldnt limit yourself to 1/8" tubing this isnt so much incorrect as its just too generic. 1/2" pvc is rigid heavy and can have 1/8" holes drilled into it very easily.

now where to get it, most plastic places will have it.

David,only now I see your question bumped
Yes it is possible to acclimate pods to 1.014 or 1.010.In fact many estuarine species do better at low salinities.

But you can't really co-rear them with rotifers.

Mmm, yah, not very good co-culture canidates IME.

 

[Luis A M]

Andy is right.A successful pod culture must be kept rot free
Rotifers will quickly take the culture and are very difficult to erradicate

Go to a dollar store, look among the party supplies.
Find the balloons, and select a package that has the long straws for holding the balloons.

Presto!
Rigid airline tubing!
(Probably food safe, considering that this stuff is aimed at kids. )

Ridged tubeing

Ridged tubeing

Where do I get the ridged tubeing to culture phytoplanktin?

 

[Kathy55g]

petco and petsmart have airline tubing

 

[reevs]

Hi Expert please help,
what kind method to increase the density or concentration of phyto, heard used the lugol solution is it right or any other pls?

thanks 'reevs'

 

[rutledgek]

I see that there are different strains of Rotifers. S and ss. Does anyone know what strain Brachionus plicatilis might be. It is at Sachs Systems aquaculture.
