Brine shrimp is a great protein-rich supplement for nearly all species of fresh and saltwater fish alike. Most local fish stores will sell brine shrimp nauplii (baby brine shrimp) or their small brown eggs. Although purchasing from your local fish store sounds more hassle-free, baby brine shrimp will not be able to fill up larger fish such as goldfish or cichlids. Pet store brine shrimp is marketed to smaller carnivorous fish like Siamese fighting fish or Tetras.
Feeding live foods to fish has many benefits. Pet stores do not usually stock live brine shrimp, with the closest brine shrimp size suitable for a larger fish being frozen or freeze-dried.
In this article, we will provide you with everything you need to know when it comes to growing out brine shrimp and feeding it to your larger fish.
What Are Brine Shrimp?
Brine shrimp are minuscule crustaceans at an average maximum size of 15 mm. The name can be misleading, as brine shrimp are not shrimp, but belong to the same family. They readily eat algae particles in the water. Interestingly, brine shrimp breathe through their legs and swim upside down. Female brine shrimp can produce offspring without the presence of a male. Brine shrimp take a particular liking to water high in salt content and naturally occur in salt-rich waters like salt lakes and the ocean.
To get brine shrimp to reproduce and be healthy for your fish, replicating their natural habitat will ensure they are growing and reproducing to the best of their ability.
Advantages of Brine Shrimp for Fish
Brine Shrimp Guaranteed Analysis
The overall GA is determined by what the brine shrimp were fed and how stress-free their grow-out conditions were.
To summarise, brine shrimp are high in natural proteins, high in fat, and provide a decent amount of fiber for most species of fish.
Brine Shrimp Maturation Conditions
If you provide the brine shrimp with appropriate maturing conditions, you can expect to have your brine shrimp reach adulthood.
Brine shrimp are not able to grow in water lacking salinity, you will need to have a constant supply of saltwater for your brine shrimp.
Setting Up the Container or Aquarium
How Long Do Brine Shrimp Take to Develop?
Brine shrimp will take approximately 3 weeks to fully develop into their adult state. The growth rate can be increased or decreased depending on the hatch rate, conditions, and appropriate food intake.
How to Hatch Brine Shrimp
Hatching these fascinating creatures is simple. The shrimp eggs are called cysts and usually have an incubation period of 24 hours. The cysts will take longer to hatch if the temperature is on the lower side. An option to promote faster hatching time, you can add in a heater if the room temperature is naturally low.
The Brine Shrimp Hatchery & Harvesting
A hatchery is a place for the eggs to incubate until the brine shrimp hatch and should be moved to the grow-out container or aquarium.
When the hatching is complete, turn off the air pump once the empty brown shells are floating. The live brine shrimp will appear to be tiny orange vibrating nauplii that will sit at the top of the waterline.
Catch the nauplii with an aquarium net and rinse them over the sink with a jug filled with fresh saltwater. Do not keep the shrimp out of the water for more than 5 seconds.
Proceed to place the nauplii in the fully set up grow-out container or aquarium.
How to Grow Out Brine Shrimp
Food Source for Brine Shrimp
In the wild, brine shrimp will consume microscopic algae particles found in the water. This may not be found in your household tap water and needs to be substituted by artificial means. Brine shrimp are only able to consume foods of particle sizes. Regular fish foods will not do the trick.
Keep the water clean by doing cautious water changes with a pantyhose over the entrance to the siphon. Adjusting the air stone to provide good surface movement will prevent the brine shrimp from suffocation.
Keep a thermometer in the grow-out set up to monitor the temperature. It is also a good idea to measure the salinity in the water using
Although a lengthy process, hatching and growing out brine shrimp for fish food has many advantages and benefits. Carnivorous fish can have a constant supply of protein-rich live foods. Overall, hatching and growing your brine shrimp saves you money in the long run. We hope this article has provided you with all the information you require to successfully start hatching your brine shrimp!
