Re: [Killietalk] Water incubation of annuals - Gibbs system
It has been quite a few years since I visited Howard and saw his set-up. As
I remember it, he pumped the air through a flat-bottomed Erlenmeyer flask
that had a rubber stopper on the top. The stopper had two holes through
which he inserted some rigid air stems. The one from the pump went into the
water and bubbled up. The exit one was above the water level and ran to the
first plastic bag containing peat (and eggs). In turn, the first bag was
connected to a second so that a series of bags received the humid air flow.
The bags were suspended to take advantage of the warmer air higher in the
room (Bill Gallagher uses this latter idea).
I'm sorry if this is an inadequate description. I do know that there has
been at least one, probably more, articles about Howard's system with a
diagram. Perhaps someone from BAKA can provide us with a fuller picture of
how Howard's system works.

Could you go into a bit more detail on Howard's method? I can't quite
picture the set-up. Do you mean like a sealed tank with a jar of water with
an airstone bubbling and bags of open peat hanging around? I'm assuming he
searched the bags regularly to check development. I know he raised alot of
occidentalis and this seems like an excellent method for that particular

Does anyone use the system invented by Howard Gibbs? Howard was a master
breeder who achieved incredibly short incubation times for peat spawners.
He hung bags with peat and eggs in a row. Using a sealed system, an air
pump was bubbled through a jar of water and then the air went into the bags
with peat. This system provided both oxygen and humidity to the bags. The
hatch occurred in weeks instead of months.
Howard's method is described somewhere. I'm not sure if it was in JAKA or
in a Bay Area Killifish Association newsletter.
