How to hatch brine shrimp eggs...


Richard

Recommended Posts

I got hold of some brine shrimp eggs from a friend... followed the instructions and added salt and the eggs to water... however... nothing has happened so far... does it need to be outdoors under sunlight? will it hatch seeing that it is quite cold now being winter?

i have it in a pail.... so does that matter? the instructions say to use a shallow pan... but i dont see why a pail would not work... my guess is maybe the temperature and sunlight?

The most affective way that i have hatch brine shrimp is by using pure saltwater this makes sure your silcity is ok . Secondly place in a bottle or jar provide plenty of aeration . I usually just place the bottle beside my tanks but with the cooler weather possibly float in an aquarium . Usuaally they hatch within 36hrs dependant on temp . On the brine shrimp packect it should also have an expected hatch rate most i think are around 80%

Hope this helps

There are many good websites showing you how to hatch brine shrimp. Either in a shallow pan or (most effective) in a cone shaped container. search google

Here's an easy way to make hatchery

http://ng.netgate.net/~jlatham/Hatch.html

Just had some new eggs in from brine shrimp direct.

http://brineshrimpdirect.com/brineshrim ... l#hatching

I follow the instruction that came with the brine shrimp eggs

- sea-water (I use instant ocean) at 25 ppt (rock-salt+magnesiumsulfate+sodiumbicarbonate will do as well, keep pH up)

- no more that 1g/liter eggs

- 28 oC

- well aerated to keep eggs in suspension

- 24 h light ( at least light for first few hours should be enough)

I get +90% hatching after 24h

Using the correct procedures and still getting poor hatching means poor quality eggs.

Just to add my experience with brine shrimp eggs :-

I use a 2 litre milk bottle. I drilled a hole in the top of the lid (big enough to fit some air tubing down). I put cold tap water in the bottle till it comes just over the bottom part of the handle. I then put in 3 teaspoon of sea salt and one teaspoon of brine shrimp eggs. I then put this into a tank of water to cover about half of the bottle (too much and the milk bottle floats.) This water has a heater in it and water is heated to 28 degrees. (I use a one foot by 6 inch tank for this). I then put an air pump on the air tubing and put this through the hole on the top on the lid and make sure the tubing goes all the way to the bottom of the bottle. Get the air going and it will bubbly away madly. I leave it for a minimum of 24 hours. I have had some good and bad hatch rates but find this is the easiest for me. When it comes time to harvest. Turn of the air pump and leave to sit for about ten minutes. I get a container that will hold all the water from the bottle. I place a hanky over the container attaching with pegs to hold firm. Then just siphon out the brine shrimp from about 1 inch from the bottom. I usually dont take all of the water etc as once I have enough brine shrimp I just return the water and leave for another 24 hours. By this time I find there is no more hatching and I syphon it out (leaving the empty shells etc from the bottom behind). Then just use a teaspoon etc to scrape the brine shrimp off the hanky and feed out. I have also frozen any extra in case and this is still eaten with relish so must be ok (but not as good as fresh).

Maybe it is not the best way but it works for me. Hope it will help if not I have writers cramp for nothing! :lol: :lol:

My way of hatching brineshrimp.

2L glass bottle (old style beer 'flagon')

3.5 tablespoons generic non-iodised salt

1500ml tap water

0.5 teaspoon BS eggs

vigourous aeration via airline to the bottom of the bottle.

I have 2 bottles indoors (in the kitchen, near a window). I

harvest one a day and start another one, ready for use

48hrs later. This time of the year, I probably should use

3 bottles to allow a bit more time for better hatching. In

summer 2 bottles (48hrs vs 72) is fine.

One thing to remember, bad eggs wont hatch. If your eggs

have been incorrectly stored (or are non-viable for some

reason) there's nothing you can do to make them hatch.

This can be a problem when you're doing it for the first time

if you're not sure that the eggs are good.

Andrew.
