My angelfish are almost capable of swimming on their own, and I have brine shrimp that should hatch tonight or early tomorrow. Would it be possible for me to freeze part of the brine shrimp so I wouldn’t always need to use live brine shrimp? juggling a full-time job and a family
Once they hatch, freeze them as soon as you can.
The nutritional content they retain in their yolk sack decreases with age…
When I have extra, I can freeze BBS without any problems.
I make use of silicone miniature ice cube pans.
As long as they consume them, you should be okay because angels are pigs even as wigglers and fry.
Although most of my angels consumed practically everything right away, others require the movement of live food, thus you might need to prepare shrimp every day for a few days or even a week.
You can buy decapsulated brine shrimp eggs to give straight to the fry.
They are not hatchable but easy to use and last a long time… Seared Brine Shrimp in Capsules
I use a sieve to strain and wash all of my BBS in clean water. Sieve for Artemia Hatching
After rinsing them, I only use a small quantity of fresh water to put the BBS into a tiny pyrex basin by pouring it through the sieve while it is upside down.
I either use a turkey baster or a big syringe to inject meat into the fry cloud from there.
One day, I let the wigglers swim freely so they could consume the entire yolk sac before I fed them.
To feed the fry, I run up to 4 hatchers at once.
The majority of my daily surplus can be fed to my other fish, therefore I make large batches for freezing.
The same URL that I provided above is where I too buy my eggs.
I receive a hatch rate of 85%.
Great eggs from brine shrimp direct hatch in 24 hours or less; I give them 24 hours.
Regards, Coral. Any advice on brining shrimp would be helpful; I’ve hatched a few batches but can’t seem to obtain the desired numbers. Have not yet perfected the “system,” if that makes sense. Would you mind sharing a photo of your setup? I wouldn’t mind raising some to feed to my adult angels or breeding guppies.
To ensure that the bubbles are at the bottom of the bottle, I use rigid airline.
No airstone; too many bubbles cause the eggs to float to the bottle’s side.
They only need a tiny bit of oxygen to prevent settling.
When harvesting, I remove the air, let the shrimp and eggs settle, and then syphon [again from the bottom of the container] into the sieve using a second [special] stiff airline.
I reuse my salt water several times until it is clear that it is not clean because the sieve fits in a little Toms Dip and Pour.
Since I already have a 75 g reef setup, using that as my only source of saltwater is the easiest thing for me. Low hatch rates at e from inferior eggs, in my opinion.
You would not believe the price and quality differences if you purchased them from a local fish market (LFS).
Utilizable brine life
The set point must be at least minus 18 degrees Celsius when the shrimp is frozen. In order to stop any present bacteria from spreading, the brine temperature might be allowed to increase to minus 8 degrees Celsius in between processing sessions.
The brine has a lengthy shelf life. Since bacterial contamination is the primary cause of brine replacement, it is crucial to define acceptable levels and critical levels of brine contamination and to continuously monitor its evolution using bacteriological studies. As soon as the brine reaches the critical level, it must be replaced.
shrimp brine components for freezing
Shrimp are brine frozen in two phases. The first step is to use brine to bring shrimp’s temperature down from a positive range of minus 8 to minus 12 degrees Celsius.
In the second step, an air blast tunnel must be heated to a deep-freezing temperature of -18 degrees Celsius. The latter is a fairly quick process that, depending on the tunnel layout, can be completed in as little as 20 minutes. The energy required to decrease the product to -18 degrees Celsius is significantly less because it is already at a lower temperature than it would be if it were being frozen in the tunnel at room temperature. Additionally, it reduces the length of the second freezing phase. The brine used in the first phase is made up of water, salt, sugar, and additions.
Water: Since water is the solution’s solvent, it must be drinking and flavorless.
Salt: Ordinary sea salt is used (sodium chloride, NaCl). Salt has the ability to lower the freezing point of water by a small amount, in addition to having an impact on the product’s microbiological and organoleptic qualities (by salting) and organoleptic quality (by having a bacteriostatic effect). The freezing point of pure water is 0 degrees Celsius, and when a specific amount of salt has been diluted, this point will go to negative temperatures.
Table 2 displays the freezing point in relation to the concentration of sodium chloride as well as the thermophysical characteristics of an aqueous solution of sodium chloride. The ionic dissociation of the NaCl molecule, which releases free Na+ and Cl- ions in the water, is how salt dissolves in water. The best method to prevent this problem is to simply take density into account when making new brine. It is a typical problem to confuse the salt concentration in the water and the salt concentration in the brine.
Keeping Shrimp Eggs in Brine
You must start with healthy, properly preserved eggs before we can move forward. All brine shrimp eggs must be kept in the following manner:
- in an airtight jar;
- without dampness; and
- in a cool setting, 40 degrees Fahrenheit or lower. (Short-term storage, defined as less than three to four weeks, is best handled by refrigeration. Eggs should ideally be maintained at or below freezing for longer-term preservation.)
When you receive your eggs, we advise dividing them into portions that will be eaten within three to four weeks and storing these portions in a firmly sealed container in the refrigerator; the remaining portions should be kept in the freezer and should also be kept in a tightly sealed container. Remember that chilling might reduce metabolic activity and postpone hatching. In order to give the embryos time to adapt, we advise taking the egg out of the freezer a day before using it.
All brine shrimp eggs, whether in opened or unopened tins, must be stored in accordance with the aforementioned rules.
Can brine shrimp withstand being frozen?
Baby brine shrimp can survive being frozen. I have personally seen the resurgence of frozen newborn brine shrimp. I purchased one of those packages of frozen newborn brine shrimp feeders.
Can you freeze baby brine shrimp?
Baby brine shrimp are a great option if you’re looking for something to feed fry or other small-mouthed fish. Hikari (r) Bio-Pure (r) Baby Brine Shrimp provide your aquatic pet with nutrition you cannot replicate at home because they are gut-loaded and frozen at their highest nutritional stage.
Can fish eat frozen brine shrimp?
“It is magnificent beyond words. My seahorses literally fell over one another. At this feeding, they were thrilled to be eating shrimp that had been “frozen.” It was almost as much of a hit with them as live shrimp! Colorado C.B
Almost all fish love the fresh, frozen adult brine shrimp that are taken from hypersaline, man-made ponds. In addition to being a fantastic supply of amino acids, it also offers a natural source of exogenous enzymes to help inert meals be better absorbed, which is crucial when feeding cultured fish. Use along with our Flake Diets Plus and/or GP Diets or other premium feeds for optimum results. Product integrity and preservation are improved by the fast dewatering and on-site freezing of the product. Flat packs with a lot of nutrition are available.
Can you cook brine shrimp that have been frozen?
Most fried dishes are of great quality and can be found in a variety of basic varieties. As indicated earlier, these foods must be available when the fry hatch and must be available continuously until they can eat conventional foods. Therefore, plan ahead to make sure you have what you need. When rearing fry, aquarium clubs come in handy because they frequently have members who can assist you when you need it. If you wish to breed and grow fish, you might want to look for a local organization that can help.
- In most tanks, particularly those with live plants, infusoria spontaneously grows. There might not be enough, though, to support the complete hatching of fry. To assure having a sufficient amount, it is helpful to culture your own infusoria. There are many suggestions for developing your own culture in this infusoria page from your guide.
- Few foods can compare to the nutritional content of newly hatched brine shrimp or their attractiveness to almost all fish. To guarantee the fry have enough, if you decide to raise it yourself, you must start the culture before the eggs hatch and maintain it for a while. Another choice used by owners is frozen newborn brine shrimp or commercially prepared live brine shrimp preparation.
- Green water: As the name implies, green water is simply water that has tiny algae growth on it. It is simple to grow and offers a great first food for baby fry. Simply fill a gallon jar with aquarium water, add some algae you’ve scraped off of your tank, and shake to mix (if you have no algae, a bit of grass will suffice). After adding a few drops of fertilizer, place the jar in direct sunlight. The water should turn green and be brimming with microscopic nutrients within a few days, making it perfect for your fry. For each feeding of the fry, remove a few ounces from the jar and replace them with purified freshwater.
- Egg yolk is a nutritious food that is simple to prepare in order to feed newly hatched fry. Hard boil an egg, remove the yolk, and compress it such that only a small amount of it pokes through the gauze. It can be hung in the tank, where the fry will eat it. For the first several days, remove and replace every day.
- DIY fried food You can generally feed live-born fry or fry that are at least a week old finely ground items that you prepare yourself.

How should brined shrimp be stored?
Can live adult brine shrimp be stored? Yes! In actuality, a lot of pet shops keep live brine shrimp in the fridge. About a quart of live adult brine shrimp were added to a gallon of fresh seawater. A flat, shallow container, such as a cat litter tray, is utilized to increase surface area. Aeration is beneficial but not necessarily required.
Are brine shrimp tolerant of warm or cold water?
The water’s ideal pH range is between 7.8 and 8. The water should be approximately room temperature (range between 20degC-25degC or 68degF-79degF). Up to 5,000 mature brine shrimp can be kept in a five-gallon aquarium (Tank 21 W 5240).
Jellyfishes consuming frozen brine shrimp
The query, “What do jellyfish eat?” is frequently asked. The majority of jellyfish adore being fed either live or frozen young brine shrimp.
Why do brine shrimp die?
Students frequently advise keeping the eggs warm by placing them beneath a pillow or in the sun. Do they spawn? At this stage, you might wish to give each youngster a jar and a spoonful of rock or sea salt.
You could now wish to inform the children that placing the eggs in salt water will cause them to hatch. Since brine shrimp can hatch in solutions with salt concentrations ranging from 1% to 6%, you will find that some eggs will hatch in mixtures created using various “recipes.”
For every pint of water, each student should add approximately one tablespoon of salt. For subsequent salinity-related experiments, this standard salinity will serve as a solid starting point.
You will see that the water level has dipped a few millimeters after the 24-hour incubation period. You might wish to use this chance to have a class discussion about the idea of evaporation. “Does the water wash the salt away?” Some of the pupils might choose to place a saltwater dish next to a heater or in the sunlight. When all the water is gone, what is left?
The newborn brine shrimp may perish if the water’s salt concentration changes quickly as a result of the sudden addition of a lot of fresh water. It’s possible that you’ll need to remind the pupils to top off the evaporated water before it runs out.
Perhaps you should warn the kids against adding too many eggs. It’s ideal to use only a pinch per pint of water. A quarter teaspoon of brine shrimp eggs per quart or liter of salt water is more than sufficient for greater amounts. Simply scatter the eggs over the water.
Do they float or sink? Some educators have promoted experiments right away, encouraging the students to dip the eggs in both fresh and saline water to observe if both hatch.
