Review & Feedback of Brine Shrimp Hatchery Dish

[Cacatuoides]

Hi brothers,

Most of you have collected your hatchery set and having fun at home....do post your comments and experience with the dish thanks!

[baranne]

Do you guys change the water every time after hatching or do you reuse the water?

I have reuse the water 3 times, including the first round....so far so good
What about the rest? having fun?

Just started the hatching process around 9pm last night and some of the eggs have already hatched within 12 hrs!

according to an article i read clealiness of the surface of the container is important.
bacteria count increases over time in unwashed containers.
this will affect the hatch rate eventually.

Good to hear that it works well

In that case i'll limit to 2 hatches then....one hatch can last for 3-4 days, so i'll probably wash the dish every week...

Any idea how long it takes for them to reach adult sizes? My marbled goby does not seems to notice the baby brine shrimp. Would need some adult sized ones for that fellow.

Simple and easy
Thanks Eman for leading this MO


wondering what's the best way to keep brineshirmp eggs huh

[Tetra Lover]

I found the brine shrimps hatched within 10hrs! My tetra fishes are veri happy with them...gobbling them up fast!

Thanks Eman for your effort in getting the shipment!

[Cacatuoides]

I'm too happy that we're enjoying the joy of feeding our fishes their favourite food at our convenience!! Saves time and the mess of the traditional bubbling method!!

I don't think the dish is able to culture adult bs that lfs are selling....they are specially produced by farms...the dish is mainly used for culturing bbs!!

[mjck]

First of all, Thanks to Eman for bringing this in for us!

Back to the Hatchery... Everything works as discussed/advertised!!! The eggs hatched within 12 hrs and the eggs shells are well separated from the BBS. Just pick up the sleve and rinse it under a tap. Harvesting BBS have never been so easy. Now my fishes are enjoying the BBS

Likes: It Works!! In fact it works great!

Dislike: The sleve may not settle into the center sometimes (it floats a little sometimes) , but no big deal considering that it works great.

Conclusion: Love It!

Eman,

Many thanks for organising the MO.

Kaganesti,

According to this:

http://saltaquarium.about.com/librar...p_Hatching.htm

in a tightly sealed container,
moisture free,
below 50 degrees F (about 10 degrees C)

Like mjck, my only beef is the sieve. It does not sit properly (tends to float up). Then you have bbs underneath it.

The article recommends SG of 1.018 for hatching. Assuming salt has a "standard" salinity (probably not true but what to do?), can anyone work out how many tablespoons or teaspoons of salt that would mean for the hatchery? I estimate the volume is about 800cc. I do not have a hygrometer and do not know how to calculate it.

Hour 14 and they are still hatching. Since you have done a couple of batches, how long till it is complete?

Also was wondering whether you've tried the hatchery with the eggs you had previously (i.e. not from BSD)? Interested to know if the hatchery improves the hatch rate?

[Cacatuoides]

I've mixed one tablespoon of marine salt with the amount of water needed for the dish....

bbs are still hatching right up to day 4 but less quantity

[tormentz]

The sieve tends to float a little as there are air bubbles trapped under it... just tilt the sieve a little to allow the air bubbles to escape and it should settle down properly.

Anyway whats the differences between the leftover eggs at the outer circles of the hatchery? Some are floating whereas some are sunken. I would assume the sunken ones are bbs shells.

And are we able to guage how much of the eggs failed to hatch properly?

[leeruisheng]

Havent collect my set but if the sieve is still floating, maybe use scotch tape and tape on the top.

Tried it but the sieve still floats a little off the bottom. Just a little too light.

Those that float are the shells after hatching. Those at the bottom have not hatch. Mine are taill hatching 16 hours after. Eman says even at Day 4.

Less at the bottom means better hatch rates. Question now is whether the eggs are good or the hatchery?

It's ok to float alitttle.. At least the bbs below can still swim out..and not trapped below.
As for hatching, i think it depends on the eggs you use. Previously i use to hatch at 12 hrs. After changing another source of bbs eggs, it takes me 16 hrs now.

I normally use up to 2 day cycle, more than that you can see alot of the dead bbs which might not be good for your fries.

Recommendation:
Instead of adding one lump amount of BBS egg once. Add substantial amount of eggs every six hours to get fresh supply of bbs..

[yaya]

The hatchery dish is separate the eggs and the BBs neatly.
Currently having apisto spawned in my 2ft tank, waiting for the fries to free swimming.

tomentz, my statement above not entirely correct. I noticed some eggs are still floating for some time when I put them in. So, while the shells after hatching float, those floating may include some unhatched eggs.

However, less at the bottom the better.
