Hatchling Trough

  • We are currently upgrading MFK. thanks! -neo
I've already collected the eggs (took about an hour to pull everything they've attached them to and manually remove them a small group at a time). They're sitting in a plastic shoebox tub on top of the main tank and i just change the water every couple of days.

once they hatch out, they'll be put in the ~5' long troughs. I'll likely add them all to a single trough at first to ease feeding. Then as they grow out i'll be transferring them to the other 3 troughs. Likely separated by color type. once they grow in all of their legs, they're ready for a new home.

The troughs will be fed via water pump from the main tank. They'll sit stagnant most of the day, the pump will turn on for an hour or two twice a day to push the old water out and introduce fresh water from the main tank. The reason for this is that they eat freshly hatched brine shrimp, so you need time for them to chow down. They also dont like a lot of current.

the overflow pipes will be wrapped in sponge/filterfloss to keep the larvae from getting sucked out, or being crushed by water pressure.

The ultimate reason for the rain gutters is automation. i wont have to manually change the water on 2 dozen shoe box tubs everyday. in fact, the water quality will be better because they'll get flushed with freshly filtered water a couple times a day instead of once.
 
Progress! Need to run the drain line down to the water level (ish), and configure my return pump and piping. oh, and add some silicone for anti slip on some stuff and seals on other things.

Getting close to completion. Need to seal up a few things, adjust the leveling on it, and add sponge to the overflow pipes to keep the hatchlings in the troughs.

The project is looking good, very innovative idea.
 
looks good. When I was in to Australian crayfish I saw a lot of hobbyist breeders use rain gutter like this to rear young. Seemed to work well.
