alanmin4304 Posted October 7, 2006 Report Share Posted October 7, 2006 How much salt per litre of water do people use to hatch brine shrimp and do you add anything else (my last lot didn't hatch too well) Quote Link to comment Share on other sites More sharing options...
Loopy Posted October 7, 2006 Report Share Posted October 7, 2006 We have a little blue scoop which we found somewhere. I can't remember where it came from or what it was for but we worked out it held about 1 tablespoon of rock salt. So when we start a new batch of shrimp we just measure out the litre of water and 1 scoop of salt. Our most successful shrimp hatches are when we follow the instructions exactly as mentioned on the card that comes with the san fransisco bay shrimp. i have played around with a couple of different methods of hatching shrimp and so far i still have to swear by the coke bottle. Where would us fish keepers be without coke bottles??? Quote Link to comment Share on other sites More sharing options...
BrineShrimp Guy Posted October 7, 2006 Report Share Posted October 7, 2006 Try this link, it will tell you just how much salt there is in natural sea water. http://en.wikipedia.org/wiki/Sea_water When hatching brineshrimp, I use normal sea water. Water collected out of Tauranga can be in the range 1024-1.030 have the temp between 26-28 (prefer 28) and they will hatch within 18-24 hours depending on brand. I use exclusivley SFB. Note: do not use iodised salt to hatch BS, they won't hatch well at all. BSG Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted October 7, 2006 Author Report Share Posted October 7, 2006 I don't have a coke bottle or blue scoop. Can you tell me how many grams/litre they suggest on your instruction card and do you add baking soda or anything? Many thanks Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted October 7, 2006 Author Report Share Posted October 7, 2006 Am I correct in assuming 1.030 = 1.030kg/litre? Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted October 7, 2006 Author Report Share Posted October 7, 2006 Sorry 1.030kg/10litre Quote Link to comment Share on other sites More sharing options...
Devon Posted October 7, 2006 Report Share Posted October 7, 2006 For mine. I use 1 table spoon per litre and then half a teaspoon of baking soda. Quote Link to comment Share on other sites More sharing options...
Alan Posted October 7, 2006 Report Share Posted October 7, 2006 1.030 is the SG of the sea water Alan. I don't know what that ratio works out to cause I get mine from the Ohiwa harbour. Try doing google on Brine Shrimp Direct, they have a good information section in that. For just hatching them no additions are neccessary, but to raise them up, more salts are required.

Devon Posted October 8, 2006 Report Share Posted October 8, 2006 So any salt water will be fine? Doesnt it matter if its cloudy? Quote Link to comment Share on other sites More sharing options...
Discusguru Posted October 8, 2006 Report Share Posted October 8, 2006 Hi Alan, i use 50grams of rock salt per ltr of water. Try hatching it in a coke bottle as i showed you with the litter nipple(hope you still have it) fix to the cover of the bottle. Ron Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted October 8, 2006 Author Report Share Posted October 8, 2006 Thanks Ron, I have just finished making it up--- Will set up the system tomorrow now I know the mix Quote Link to comment Share on other sites More sharing options...
BrineShrimp Guy Posted October 8, 2006 Report Share Posted October 8, 2006 I have never used rock salt for BS, I have always used natural sea water, but if you use anywhere between 35-50g rock salt per litre you should be fine. You may also have to add bicard to bring the PH up to near 8.0 to improve your hatch rate if it is down. BSG Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted October 8, 2006 Author Report Share Posted October 8, 2006 Thanks all-----I will set up Ronnies wee machine today and try the mix suggested----keep you posted Quote Link to comment Share on other sites More sharing options...
JoandWilly Posted October 8, 2006 Report Share Posted October 8, 2006 I use 2 table spoons of sallt for a litre of water, and i use water out of the african tank so water is always around 8ish and then one tea spoon of eggs, and let them sit for about 36 hours, was finding wasnt getting a good hatch rate after 24 hours.

BrineShrimp Guy Posted October 8, 2006 Report Share Posted October 8, 2006 JoandWilly what brand of cysts are you using? 36 hours indicates a low yeild brand or low temp for the most part. Other facters affect hatching, but these seem to be the ones that affect hatching the greatest. BSG Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted October 15, 2006 Author Report Share Posted October 15, 2006 Ronnies wee idea works a treat with a heater in it---happy as. Quote Link to comment Share on other sites More sharing options...

JoandWilly Posted October 15, 2006 Report Share Posted October 15, 2006 Yeah mines low temp i think, i sit them in a tank which is only around 25-26, using the brand that comes in the blue tins. Quote Link to comment Share on other sites More sharing options...
shiuh Posted October 15, 2006 Report Share Posted October 15, 2006 i set mine up in the one of the kitchen cabinet and install a couple of bulbs in there to set the temperature right. works out really well, shell on top bbs on the bottom. just dont tell the mrs.

alextret Posted November 25, 2006 Report Share Posted November 25, 2006 How do they manage to prevent salt water from mixing with fresh water and still allow brine shrimp out? I could not figure out from looking at the pictures. Unless shrimps can walk over a dry area (which they can't), it appears to contravene the second law of thermodynamics.

jim r Posted November 25, 2006 Report Share Posted November 25, 2006 freshwater sits on top of saltwater (like the fiords in the South Island) I assume they just swim from one to the other. Quote Link to comment Share on other sites More sharing options...
