The Indian prawn is a global seafood staple with a complex, high-tech production cycle.

In short: From traditional paddy fields to intensive, high-density hatcheries, the Indian prawn is a major commercial species. While it thrives in the Indo-West Pacific, its farming requires precise control over salinity, diet, and even the endocrine systems of broodstock to meet the massive global demand for this versatile crustacean.

The Indian prawn, known scientifically as Fenneropenaeus indicus, is a marine decapod that plays a significant role in global fisheries and aquaculture. Found across the Indo-West Pacific, from Africa to Australia, these shrimp spend their early developmental stages in the sea before migrating to estuaries as juveniles. They eventually return to the ocean as sub-adults, where they can reach lengths of about 22 centimeters and live at depths of up to 90 meters. Despite their commercial importance, they have faced scrutiny; in 2010, Greenpeace International added the species to its seafood red list, not because the prawn itself is threatened, but due to the high levels of bycatch—including endangered sea turtles—associated with capture fishing methods.

Cultivating the Indian prawn involves a sophisticated array of techniques, ranging from extensive traditional systems to highly mechanized intensive farming. In traditional systems, such as the 'pokkali' paddy fields in India, farmers rely on tidal cycles to bring wild seed into ponds. In contrast, intensive farming utilizes small, tightly controlled ponds with high stocking densities of 50 to 100 post-larvae per square meter, requiring daily water exchanges to maintain health. Because seed supply is a limiting factor, hatcheries have become essential. Here, managers may use eyestalk ablation—a technique where a female's eyestalk is removed to stimulate endocrine activity—to induce spawning, though this process can produce less hardy fry compared to natural methods.

The economic landscape for the Indian prawn is defined by a balance between production costs and market value. While it generally commands a lower price than the related P. monodon, its relative ease of breeding and rearing can make it a profitable venture for farmers. Production costs are influenced by the chosen scale and intensity, with seed production estimated at US$1.6 per 1,000 units and adult shrimp fetching US$4 to US$5 per kilogram. As the industry evolves, producers are increasingly looking toward value-added products, such as pickles and ready-to-cook items, to maximize returns in a competitive global market.
