China is also a significant importer and processor of other red shrimp species, including Argentine red shrimp, for both its domestic market and re-export.

3. Habitat and Biology

Red shrimp species inhabit specific marine environments, with their biology and behavior closely tied to oceanographic conditions.

• Argentine Red Shrimp (Pleoticus muelleri): This species is a bottom-dweller (demersal) found in the Southwest Atlantic Ocean, primarily in the coastal waters of Argentina’s Patagonia region. Its distribution is concentrated in key areas like the San Jorge Gulf. The species has a relatively short reproduction cycle, fully reproducing in 12 to 16 months, which contributes to the resilience of its stocks.

• Chinese Red Shrimp (Solenocera melantho): This species is predominantly found in the East China Sea and the Yellow Sea. It is a key resource in these ecosystems, with its main catching season occurring from August to October, following a fishing ban from early May to the end of July.

4. Scientific and Commercial Names

The nomenclature for red shrimp can vary by species and region.

• Argentine Red Shrimp:

  • Scientific Name: Pleoticus muelleri.

  • Commercial Names: Most commonly known as Argentine red shrimp or Patagonian shrimp in international trade. It is also referred to by its Spanish name, “langostino patagónico”.

• Chinese Red Shrimp:

  • Scientific Name: Solenocera melantho.

  • Commercial Names: Marketed as red shrimp or pink shrimp.

5. Wild Catch Development History

The wild-catch fisheries for red shrimp have experienced significant evolution and growth.

The Argentine red shrimp fishery has developed from a smaller, regional operation into a major global industry. In the mid-1990s, the fishery faced challenges from overfishing and an oversized fishing effort, which led to the implementation of specific management tools to protect the stock. Advances in harvesting techniques, processing, and management have since helped grow sector landings dramatically, allowing for expansion into new markets like China and the United States. The fishery has also embarked on sustainability journeys, with Fishery Improvement Projects (FIPs) launched for both the inshore and offshore fleets, aiming for Marine Stewardship Council (MSC) certification.

6. Core Catch Regions

The catch of red shrimp is highly concentrated in specific, productive marine regions.

• Argentine Red Shrimp: The core catching regions are concentrated in the Patagonian waters of Argentina, particularly the San Jorge Gulf. The fishery is managed in two main components: an inshore fleet operating seasonally along the coast of Chubut province, and an offshore fleet operating in federal waters.

• Chinese Red Shrimp: The core catch region for Solenocera melantho is primarily around Zhoushan city in Zhejiang province, within the East China Sea and Yellow Sea.

7. Nutritional Value

Red shrimp are a nutritious and healthy seafood choice, rich in essential nutrients.

They are an excellent source of high-quality protein and are low in calories and fat. A standard 84g (3 oz) serving provides 15g of protein, contributing significantly to daily protein requirements. Shrimp are one of the best food sources of iodine, important for thyroid function, and provide other minerals like iron. They also contain omega-3 fatty acids, which support heart and brain health.

8. Main Product Types

Red shrimp are processed into several forms to meet diverse market demands.

• Frozen Shrimp: This is a primary product form, particularly for Argentine red shrimp, which is often frozen at sea (FOS) to preserve quality. Frozen Chinese red shrimp is also a major export product.

• Head-On and Headless Shell-On: These formats are popular for retail and foodservice, with head-on varieties often marketed as a premium product for their visual appeal and flavor potential.

• Peeled and Deveined (P&D): A convenient, value-added format that is widely used in food service and retail.

• Value-Added Products: This category includes cooked shrimp, marinated products, and shrimp included in ready-to-eat meals.

9. Global Market and Trade

The global market for red shrimp is dynamic and has shown substantial growth.

• Key Markets: Argentine red shrimp exports have traditionally gone to Spain, but have seen explosive growth in China and the United States over the past decade. U.S. imports, for example, grew from around 200 MT in 2011 to 4,500 MT in 2016. Chinese red shrimp are exported to most EU countries, the Middle East, North Africa, Japan, and Korea.

• Market Dynamics: The overall shrimp industry is navigating shifting trade dynamics, with a focus on sustainability and innovation. Global demand for Argentine red shrimp has been increasing steadily, driving up landings and prices. The vast and growing Chinese market, with its rising per capita seafood consumption, is a critical destination for shrimp from around the world.

10. Catch Technology

Red shrimp are primarily caught using targeted trawling methods.
