Hi, just wondered if anyone else has had similar problems to me with their brine shrimp hatchery. I bought some eggs with a 93% hatch rate. The first batch took 3 days to hatch and wasnt a very big haul, the second lot died and the third batch that I am doing now still hasnt hatched after a day.
I know that temperature probably has a lot to do with it, and unfortunately here in the uk after having a minor heat wave recently, it is now very cold here, so as I didnt have a lamp I used a bain marie system, heating water for the glass jars to stand in, but think I may have fried the 2nd batch accidentally. I watched a tutorial last night on youtube, on how to raise a batch using a lamp as a heat and light source, and an upturned plastic bottle.
I bought a lamp today, unfortunately here in the uk, we have to use energy saving light bulbs which dont produce any heat, on a good note I managed to find an old style bulb to produce some heat and I am awaiting a result soon, hopefully.
So I have the batch I started last night, with no results as yet, and a new batch started this evening, I am finding though that the two bottle method is quite difficult to keep the pressure from the air pump level in both bottles, it fluctuates dramatically if you move anything, so I have air hoses strapped to chop sticks to keep them rigid, and a clamp to reduce the flow from one of the hoses to raise the flow in the other, both held above the top of the bottle with a peg to keep them level.
And then trying to turkey baste the shrimp out into a piece of kitchen towel without losing them?? Help??
This is so much more difficult compared to daphnia. Ahhhh!!!!
Any advice please??
