Tutorial: Decapsulated Brine Shrimp

[cradleofify]

when you put in your bleach does it tend to overflow with bubbles?

i use white king bleach, should i be using clorox?

[saltlakebrineshrimp]

@cradleofify It sure can....this happens with dirty egg.



[kingcrimson234]

can you eat the dry brine shrimp eggs?

[saltlakebrineshrimp]

@kingcrimson234 I guess you could...I wouldn't however. :)

[JUNAID187]

how long can you keep the decapsulated shells ?

[saltlakebrineshrimp]

@JUNAID187 If you dehydrate the embryos, they will last for years.

[lfclikewalfc]

dp they need de chlorinated water?

Hi!

I just tried this yesterday. Now, i wonder, I used those eggs that i couldnt hatch which is i think 0 % hatch rate. I decap 1 teaspoon and then tried to hatch. Today after 24 hours, i havent seen and nauplii swimming around(which should be seen after 15 hours?). The question is, if you have bad eggs or 0% hatch rate, is it always 0 % hatch rate even if you decap it? if yes, is it still wise to feed those unhatched decap eggs to your fry(i mean, protein, etc)?

[saltlakebrineshrimp]

@christagoh Good questions. If eggs have a 0% hatch-rate then they will not hatch. Decapsulating brine shrimp with low hatch-rates (10%-25%) dissolve ALL shells and make it possible to have 10%-25% alive and swimming while the remaining 75%-90% stay in their embryo (basically dead). These unhatched embryos however are still great for your fish, and very digestible (with out shells). Their energy content is also higher than hatched brine shrimp as they do now expend energy to break the shell.

[christagoh]

@saltlakebrineshrimp Hi! Thanks for the reply! I glad to know that i can still used those 0% hatch-rate eggs. But I stil have some question about it. If the embryos are still alive(or I mean still can be feed to my fry), why cant they hatch? I read about feeding fish with decap BS egg, and just like you said , its better than the hatched egg since their energy hasnt been used. But if the eggs doesnt hatch, does it mean that it doesnt have much energy on it since they cant break the cysts?

[JeanMarx1982]

hello friend I have a question I need a light source for the Artemia hatches?

[saltlakebrineshrimp]

@JeanMarx1982 yes...a light source is needed for optimum hatch rate.

[qaibettaroom]

great informations, thanks!!!!!

[MarcusLKF001]

where does the shell go? 0.o

[denisesfeathers]

Hi I am looking to grow brine shrimp. I have full grown fish and my firemouths will not eat the hatchings. But I think they may eat adult ones as they like feeder guppy fry. I have tried to raise them but they die on me. What do I feed them and how often and can I keep them in the one leader bottle.

[saltlakebrineshrimp]

@denisesfeathers It is best to feed the freshly hatched brien shrimp 24 to 36 hours after harvest. Growing brien shrimp to adulthood is very difficult as they will die in the hatching cone. You would need at lest two large tanks,

and then transfer the brine shrimp into the other salt water tank once a week, clean the tank they were just in, make a new saline solution and continue with the transfer once a week, feeding spirulina powder or bakers yeast. It is possible, but very time consuming.

[azizborashed]

what do you feed the shrimp

[saltlakebrineshrimp]

@azizborashed Spirulina Powder and bakers yeast

[kluwkidd]

I have never done this before, but what would be the easiest way to seperate the egg shells from the decapsulated brine shrimp after rinsing it out? I speculate that even after you have seperated the two, they are still in the coffee filter when you filtered the bleach solution out.

[saltlakebrineshrimp]

@kluwkidd: Thanks for your question. When you Decap brine shrimp it actually chemically removes the chorion or shell so they are "shell-free." This makes it so you do not need to separate anything. You may feed the decap directly to your fish (after rinsing of course) or continue to hatch the decap in your hatching container...then you can feed everything in the hatching container to your fish without any worries of introducing shells. I hope this helps.

[chrisaquarium]

Ok, this is a decent try at a video - however - the coffee filter takes WAY too long to rinse! By the time you're rinsed, your decap brine is dead! Need a better filter...poor choice.

[saltlakebrineshrimp]

I agree. A coffee filter takes longer than a brine shrimp net. However if you are unable to find a brine shrimp net, a coffee filter will work just fine. I have used it serveral times and never once had problems with the eggs cooking or artemia dying. But I do agree that a brine shrimp net is by far superior. Thanks for your comment.

[chrisaquarium]

@saltlakebrineshrimp The best thing I've found to rinse the eggs through is a rotifer seive. You can get them online. Its only worth while if you do this A LOT. Google Rotifer Seive. Its basically just a reusable fine seive.

[saltlakebrineshrimp]

@chrisaquarium THanks for the information. I too use a different type of filter...however I wanted this video to be able to show people what to buy at their local wal-mart. But thanks for your post.

[St33lCrush3r]

hi, do you have to add any dechlorinator into the tap water?

[saltlakebrineshrimp]

@St33lCrush3r: I have never added any dechlorinator into my tap water...however I am sure that all tap water is different. There is available a Chlorine Water Tester (bascially test strips)...If you are worried I would recomment using these to get the correct balance.

[youstubeblows]

Vinegar is a better rinse when dealing with Bleach.

[honeybees1]

How is it that the bleach doesn't burn and kill the eggs?get that in your eyes and your screwed I would think the same for eggs.

[saltlakebrineshrimp]

@honeybees1...You are correct, in that if you leave the eggs in the bleach too long you will have "non-hatching" decapsulated brine shrimp. This would basically "hard boil" the egg. Again it is very important to watch the coloration change so you only take off the chorion, and not cook the egg. We decapsulate brine shrimp in our industry all the time. Infact our company produces non-hatching decap at the rate of 500-600 lbs per day. You just need to be careful when using chemicals.

[jeenagail]

hi i have everything ready now, i just wanted to know if i can feed this to my saltwater fish and corals? just a bit nervous.. thanks

[HuntersHuntDickTwo]

Brine shrimp aren't salt water.

[saltlakebrineshrimp]

Brine Shrimp ARE salt water creatures. They are harvested from the Great Salt Lake, Utah. Depending on the year the salinity fluctuates...but a good average is about 10% salinity in the GSL.

Remember to thoroughly rinse the bleach from the eggs if you are doing the decap method before introducing to your tank.

[jeenagail]

hi again! can you freeze the rest of the baby brine shrimp that is was not eaten into the fridge and feed it again after a few days?

[saltlakebrineshrimp]

Totally. If you have Decapsulated brine shrimp you will want to store it in a saturated brine solution and keep in the fridge.

If you have already hatched the brine shrimp it is best to rinse in fresh water (as salt water does not freeze well) and then freeze the amount you would like to feed to your fish in ice cube trays. Each cube would be one feeding. This works really well. As the ice melts in the tank the fish continue to eat!!!

[tks068]

hi , just a curious question, wont bleach kill those fish and the brineshrimp in the process ?

[saltlakebrineshrimp]

Thanks for your question. Always rinse the bleach off..."until there is no more bleach smell" with the coffee filter or brine shrimp net (shown in video). If you leave the brine shrimp in the bleach solution too long it will "cook" the eggs and therefore they will become a non-hatching product. I hope this helps.

[thatfishbreeder]

I would try this but are you sure you have to use that much bleach?? That's quite alot.

[saltlakebrineshrimp]

There are many factors for the amount of bleach used and time left in the solution...you mostly must find what works for you. The concentration of Sodium Hypo in the Bleach (i.e. is it 4% or 25%?). If stronger you could dilute it. What is the stocking density? (i.e. less egg = less bleach). The cysts corion (shell)...is this from a harvest year where the shell is thick or the thin? (as no two harvests years are the same.) I showed what works best for me. I hope this helps. Good Luck!

[TheAquaSpecialist]

Why would u want to decap them?

[saltlakebrineshrimp]

There are several reasons...the biggest is perhaps that if you had a lower hatchout rate with a poor separation, decapsulating them would eliminate the cysts and increase your hatchout. Your fish would also be able to consume even the unhatched brine shrimp without worries of cysts lodging in their digestive tracts. Also if you didnt want to spend 24 hours waiting to hatch the BSE, you could do this in 10 mins and feed directly to themjust rinse the Sodium Hypo off! :)

[TheAquaSpecialist]

Oh wow!

I will try this.

Can I sill feed them to fry?

[saltlakebrineshrimp]

Fry love decap...if you feed the decap(without hatching them) the size of the embryo is about 230um versus 430um for a nauplii (baby brine shrimp). Decap also carries higher nutritional value as the BBS have not or will not use as much energy to burst the corion (shell). The only negative of not hatching decap is they are not alive and moving which could be problematic for predators that enjoy the chase. Let me know how they like it!!!
