“Is It Shrimp Brick or Shrimp Poop? A Guide to Deciphering the Difference”

While shrimp paste is a delicacy fit for consumption, shrimp roe is not meant to be eaten. It's no wonder that this distinction has left many home cooks bewildered.

Many people are unsure about the best way to peel and prepare shrimp to fully enjoy its intestines and roe. Therefore, it’s essential to first understand the anatomy of this crustacean.

Let’s delve deeper into the world of shrimp intestines and roe through the insightful post shared by Ms. Nguyet.


The shrimp used in the post is of medium quality, with approximately 20 shrimps per kg, priced at 150,000 VND/kg.

First, let’s enhance our knowledge about shrimp. Scientifically, shrimp roe, similar to crab roe, houses the reproductive cells. In shrimp, the roe is concentrated in the head region. In males, it comprises the entire system for producing sperm to ensure the continuation of the species. For females, the roe is their ovaries. During the breeding season, mature eggs descend into the female shrimp’s abdomen/apron, where they are fertilized and protected for a period before being released into the external water environment to hatch.

Now, let’s talk about shrimp intestines. Similar to the shrimp roe, the intestines are also located in the head region, tucked inside a tiny sac-like stomach directly connected to the digestive tract (as indicated by the black line on the shrimp’s back, extending towards the tail).

Similar to wild and farmed fish, the stomach of wild river shrimp is usually small, and their intestines are barely noticeable. However, the intestines of farmed shrimp are more visible, appearing as a dark-colored mass in the head region. When cooked, this mass hardens and can be easily spotted inside the tiny stomach sac, resembling the tip of a small chopstick.

Unlike the intestines, shrimp roe boasts a vibrant yellow or orange color and a rich, fatty flavor. The deeper the green color of the shrimp’s shell, the more attractive the color of its roe. As with durian, some people find the smell of shrimp roe pleasant, while others find it unappealing.

Ms. Nguyet, a resident of Vĩnh Long in the Mekong Delta region, also known for its abundant shrimp supply, particularly in areas with brackish water like Bến Tre, Cà Mau, and Kiên Giang, shared her expertise on the subject. She added, “I’m an expert at grilling and peeling shrimp for others, especially at parties. I take pride in skillfully peeling shrimp, ensuring the roe remains intact and the meat untouched.”

Remember to properly peel and prepare shrimp before enjoying steamed or grilled dishes to get the most out of your culinary experience!

Frequently asked questions

Shrimp brick, also known as urates, is a combination of minerals, pigments, and nitrogenous waste. It is a normal part of a shrimp’s digestive process and is usually passed out along with fecal matter. However, when shrimp are stressed or their environment is not optimal, they may expel these urates separately, forming small, hard, brick-like pellets.

Shrimp poop, or feces, is the undigested remains of what the shrimp has eaten. It is usually brown or green in color and has a softer, more paste-like consistency compared to shrimp brick. Shrimp poop is often expelled in small pellets or strings and may be found stuck to the shrimp’s body or floating in the water.

There are several reasons why shrimp may expel shrimp brick. Stress is a common factor, which can be caused by poor water quality, overhandling, or aggressive tank mates. Additionally, a buildup of toxins in the shrimp’s system or an imbalance in their diet can also lead to the formation and expulsion of urates.

The key differences are in their appearance and texture. Shrimp brick is harder, drier, and more compact, resembling small bricks or pellets. It is often white, cream, or light yellow in color. On the other hand, shrimp poop is softer, moister, and may have a more irregular shape. It is typically brown or green, depending on the shrimp’s diet.

Finding a significant amount of shrimp brick in your tank may indicate that your shrimp are stressed or that there are issues with water quality. Check your water parameters and ensure that the environment is optimal for your shrimp, including proper temperature, pH, and ammonia/nitrite levels. Also, review your shrimp’s diet to ensure they are getting a balanced and varied nutrition.
