Shrimp fry is a term that is often encountered in the world of shrimp cultivation. What exactly is shrimp fry? Find out the full explanation through this article!
What is Shrimp Fry?
Shrimp fry refers to shrimp ‘seeds’, a common term used for shrimp in the post larva life stage. In shrimp cultivation, farmers usually obtain shrimp fry before starting their cultivation. The fry is stocked or spread in the pond to grow into adult shrimp, ready for harvest.
Origin of the Term ‘Shrimp Fry’
The term shrimp fry originates from the Anglo-French language in the early 14th century, which means “young fish”. In Old French, frier or frontier means to spawn in the sand. Now, the specific term ‘fry’ is used to distinguish between the seed of shrimp and other animals.
Shrimp Fry Facts
After understanding what shrimp fry is, here are some facts about shrimp fry you might not know.
1. Produced in hatcheries
Shrimp fry is hatched in a business unit called a hatchery. Hatcheries play a crucial role for the shrimp cultivation industry.
Shrimp fry in the hatchery originate from shrimp broodstock, capable of producing 100,000-250,000 eggs at once. However, only about 40% of these eggs reach the post larvae stage.
2. Physical appearance of fry

If you haven’t seen a shrimp fry in real life, you might not know what it looks like. Shrimp fry has an antennae and tail. It has a straight and transparent body with shiny eyes.
3. The quality is reflected through certification
High quality shrimp fry is needed for a successful shrimp cultivation. The quality of the fry can be seen from whether or not it has the Specific Pathogen Free (SPF) and Specific Pathogen Resistant (SPR) certification.
Fry with SPF specification is free of pathogens (especially viruses), which might cause diseases. Non-SPF fry pose the risk of catching or carrying diseases during cultivation.
On the other hand, SPR shrimp fry is resistant towards specific pathogens. Not all SPF shrimp fry has SPR certification, but SPR fry does not need SPF certification.
4. Fry should pass the stress test
Quality shrimp fry must undergo stress testing to determine their survival rate. Stress testing is conducted using freshwater or 100 ppm formaldehyde for 30 minutes. Healthy shrimp fry will pass with a survival rate of over 95%.
Conclusion
Shrimp fry is a term for shrimp seeds. They are produced by hatcheries to be bought by shrimp farmers and used in their shrimp farming activities. Quality shrimp fry must have SPF and SPR certification and pass stress testing.
If you're looking to start a business as a shrimp farmer, make sure that besides using quality shrimp fry, you also monitor the development of your pond conditions throughout your cultivation cycle.
