Space Fish: ISS Aquatic Habitat Delivered By HTV-3 68

astroengine writes "Yes, it's the moment we've all (secretly) been waiting for: Fish In Space! But before you go getting too excited and start asking the big questions — like: if there's a bubble in a microgravity aquarium, what happens if the fish falls into it? Let's ponder that for a minute... — it's worth pointing out that the fish aren't actually in space right now (their habitat has just been delivered to the space station by the unmanned Japanese H-II Transfer Vehicle 'Kounotori 3') and this fishy experiment isn't just to see how fish enjoy swimming upside down, there's some serious science behind it."

    Not that new...this experiment is derived from one flown on the Shuttle a few times already. This is mostly an extension of the previous research. What I am really interested in is the egg-to-egg possibility--the system is designed to support up to three generations of fish, so they will be able to observe whether zero-gravity causes intergenerational changes (eg., whether the children of those born in zero-g are as fit as those born of one-g fish, or as one-g fish themselves). This is a significant challenge for any possibility of space colonization, so experimentation in it is quite welcome.

    In particular, goldfish [] and newts flew on STS-65 (1994). Not sure if complete life-cycle experiments have been done before. Some quick searching turns up this speculation [] (Google Books preview) as of 2003 that fish will soon become the first vertebrate to live a complete life cycle in space.
