Baby Halocaridina rubra

Halocaridina rubra, the Hawaiian red shrimp or volcano shrimp is a small red shrimp of the family Atyidae, with the common Hawaiian name ʻōpaeʻula (meaning "red shrimp")

Here's a list of my Blogs starting with setting up the tank introducing the Shrimps and then them growing :-
and finally the Females 'berried' i.e. carrying eggs
they carry the eggs for a few weeks then scatter them, they hatch and spend a couple of weeks hanging head down as Larvae, in the water, absorbing their yolk sack before emerging as Juveniles

I'm pleased, just thought I'd share

Another Sluice Mod.

Although the Sluice caught Gold I found it hard to set up to get the water flow right
at over 4' I found either one end or the other ended up under water so shortened the body by 1' and the flare by 6" and also made an adjustable dam to sit it in, to give the initial slope, I've not tried it yet but am hoping once set up I can just lift it out of the dam, to empty, then straight back into it and carry on, without having to mess about proping it up with flat rocks to set the water flow up again

 I'll give the 'bank holiday' traffic madness a miss and hope to head North later next week to try it out

Mennock Pass - again

I altered the tarp awning to make it easier to put up, bolt a strut to the roof rack put the pole in at the other end - free standing, same for the other two then bolt the cross braces to give a ridged structure
the tarps cut to size and joined with nut/bolts and washers, so just slips over then is fastened to the roof rack, pole tops and bottom of poles with washers and wing nuts, the door fixes over the first strut and slides to open and shut
I'd no bother setting it up by my self when I arrived

I'd built a Rocker/Box Cradle to try out, but should have tried it out at home as it needs a few tweaks ! it works but is too slow

I'd built a new Sluice as well and again this needs a big tweak ! like make it a foot shorter, it catches Gold but is hard to set up with the right water flow/ slope angle

I spent a couple of hours cutting new matts for it from the Rocker Box matts
but wished I'd brought the Flower Trough Sluice from the June expedition
which worked great and was easy to set up. Lucky though a couple of 'panners' passing by said they were coming back Sunday and would bring a spare small Sluice I could borrow for the day.
So I spent a couple of days digging pumping and riddling to 1/2" and piling it on a tarp
they arrived on Sunday and I ran it through

it certainly caught Gold right down to dust sized specks. I panned a couple of pans there but brought the rest of the concentrate back to pan at home and I've still 1/2 a bucket to do

I enjoyed the Tour and learnt alot for next time
