failed egg transfers ???

[ctenophors rule]

Hello

Is it possible to salvage a failed egg transfer?

As far as I remember (and please correct me if I am wrong, that is why I am posting) The exact point of fertilization is uknown, but it is believed to be before the egg trasfer. I also understand that the male provides the larvae with neccesary trace elements and nutrients to grow while en vitro. is it possible to supply this life giving solution out side of the males body? have the water paramaters of the egg pouch been analysed? has this been done before successfuly?

thanks guys!

I've never heard of anything like that being done in the 8 years I've been reading on seahorses.
If it is being done, I would suspect it would occur in a laboratory, not in a hobbyist's home.

thats not entirely out of the realm of possibilities at this point.

I believe that the male's pouch has been described as having placenta like qualities to it, which would mean that it at least transfers oxygen and takes away wastes much like the male clownfish does when it fans its eggs (except the horse does it internally.) I also thought that it was known that the male fertilizes the eggs after they are in the pouch, so his is a true pregnancy. I've got a pounding headache, though, so I may be off on that, but it is what I recall.

I agree with the male fertilizing the eggs once they are put into his pouch. I have observed many egg transfers and the male does a shaking motion after the transfer which I believe may be where he fertilizes the eggs. I wouldn't worry though, they will attempt another transfer.. sometimes it just takes a little practice

no longer considered to be the case. the male fertilises the water just before the egg transfer.

yes the male controls many variables within the brood pouch. from salinity, to prolactin, oxygen, trace element concentrations, etc.

Interesting... I haven't seen this documented anywhere.. could you please provide where you obtained this information? I would be very interested in reading the article

that would be it i believe. I have been looking for some of the scientific journals regaurding the subject, but their aren't on gale, and i need the library to access jstor

if anyone can access them, can you post the link

BTW. seahorse eggs have been reared to ten days post hatch (after which i assume they were humanely euthanised) outside of the males pouch. (J.R.Linton & B.L.Soloff.)

This is some interesting reading...thank you for the link
