Where Do Argentine Red Shrimp Come From?

Argentine red shrimp are native to the southwestern Atlantic Ocean along the coasts of Argentina, Brazil, and Uruguay. Their scientific name is Pleoticus muelleri. They inhabit the cold, nutrient-rich waters of the Patagonian Shelf and the Argentine Sea.

Commercial fisheries first started harvesting these shrimp in the 1980s off the coast of Mar del Plata, Argentina. Since then, the fishery and export market has boomed. The majority of the global supply now comes from Argentina.

How to Identify Argentine Red Shrimp

It’s easy to recognize Argentine red shrimp by their distinctive crimson hue Their shells appear more red than pink and are often described as translucent. When cooked, the flesh takes on a lighter pinkish color

They have 10 legs like all shrimp, with front claws that are smooth rather than spiny. Adult shrimp reach around 4-6 inches long on average when fully mature. Their bodies are straight with a tapered abdomen.

Unique Biology and Lifecycle

Argentine red shrimp have an interesting lifecycle that sets them apart from many other shrimp species:

• They live up to 4 years, which is unusually long for a shrimp.

• Females grow much larger than males and can reach sizes over 8 inches

• The larvae go through a complex metamorphosis process including nauplius, protozoea, mysis, and postlarvae stages.

• Shrimp become sexually mature and able to reproduce around 2 years old. The females brood fertilized eggs until ready to hatch.

• Juveniles will molt and grow into adults once reaching ideal conditions of water temperature and salinity.

Eating Habits and Ecosystem Role

In the wild, Argentine red shrimp are omnivorous bottom feeders. Their diet consists of phytoplankton, zooplankton, mollusks, and other small invertebrates.

These shrimp play an integral role in the marine food web. They feed on plankton and detritus near the ocean floor, recycling nutrients back into the ecosystem. At the same time, they serve as a key food source for larger predators like fish, squid, marine mammals, and seabirds.

Commercial fishermen use bottom trawlers to harvest Argentine red shrimp. The shrimp are caught year-round, with peak season from November to June. Most shrimp are frozen onboard the fishing vessels.

The two main products are head-on shell-on (HOSO) and peeled/deveined. Popular peeling styles include easy-peel, cocktail, and butterfly. Shrimp sizes range from 31-40 per pound up to 16-20 per pound.

The United States imports around 20 million pounds of Argentine red shrimp annually, making it the largest international market. Domestically, you can find fresh and frozen options at specialty seafood markets or large supermarket chains. Prices range from $10-$20 per pound.
