Ghost shrimp are popular prey for various fish species, including larger fish, as well as crabs, some species of birds, and other aquatic predators. Additionally, some land animals like raccoons and turtles may also feed on ghost shrimp when they venture into shallower waters.
The answer depends on the type of shrimp, all penaeid shrimps spawning takes place in the ocean, usually a female produces from 500,000 to 1,000,000 eggs and can spawn many times, it is thought that brown and pink shrimp spawn in October and November, however in some areas spawning occurs during the late winter and early spring.The exact spawning time seems to be in condition with water temperature. White shrimp typically spawn in May and June with some as late as August.Please see related link below!
Yes, it is possible to artificially incubate freshwater shrimp eggs. The eggs can be collected and transferred to a separate container with controlled water parameters such as temperature, pH, and salinity. The eggs will then hatch within a specific time frame under these controlled conditions, allowing for successful incubation.
Brine shrimp are used as food for small fish. I don't know what's in most kits, but I do know how to hatch shrimp from eggs. Add a tablespoon of sea salt, aquarium salt or rock salt to a litre of water (4 tablespoons/gallon) and mix well till all the salt dissolves. Pour some of the salt mixture into an empty, well washed soft drink bottle. It should be about 3/4 full. Depending on how many nauplii (baby shrimp) you need, add up to one level teaspoon full of eggs. Drop an airstone into the bottle and plug it into the most powerful air pump you have. Turn it on. The eggs must not settle or they will not hatch. Make sure they are tumbling constantly. After about 24-48 hours, turn off the airstone and put the bottle in the dark. Egg shells and eggs that did not hatch will either float to the bottom or sink now that the current is gone. These must not be collected if possible as they will clog up fry that eat them. About two hours after putting the bottle in the dark, shine a torch at one side of the bottle about halfway up (keeping the rest as dark as possible). The shrimp will be attracted to the light and will form a clump. Use a length of airline to siphon them out into a small container. Strain them through pantyhose and then rinse briefly in tank water (not chlorine which will kill them instantly) to remove the salt. They can now be fed to your fry. Note that they will only live for about fifteen minutes in freshwater; you should only collect as many as your fry can eat in five to ten minutes as they usually lose interest once the nauplii are dead. If you want the nauplii to survive more than about 24 hours you have to feed them. You can buy brine shrimp food at most pet stores that sell the eggs. They grow extremely quickly and will not be a suitable size for newly hatched fry after about a day. It is therefore usual to hatch only as many as your fry will eat in about a day, so most fish breeders that use baby brine shrimp as a first food have several soft drink bottle hatcheries going at once. It is usual to start hatching brine shrimp when the fry hatch so by the time they become free swimming and are able to eat, the nauplii are ready to harvest. If you choose you can grow on some of the baby shrimp for a breeding colony. Once hatched they like still water and do not need filtration. Use a bare gallon jar and continue feeding them. Change the water about 50% per week. If well looked after the shrimp will breed but will not supply eggs in suitable quantity to feed fry, unless they are used as a supplement to the diet of a small number of fry. Once the fry are larger I recommend switching to vinegar eels or microworm as the live food. These foods should not be used alone but in conjunction with crushed high quality flakes. Both are easy to culture. Microworms can be grown in a mix of oats, water and yeast. Vinegar eels grow in apple cider vinegar. Both are tiny and suitable for fry at about 5mm of length. They are much cheaper foods than continually buying brine shrimp eggs as by this stage the fry will be going through a lot of baby brine shrimp.

Sea Monkeys were a popular children's past time toy during the 1960's. The "Sea Monkeys" are actually a kind of small brine shrimp that came to life once awaken by water.
