Sustained profitability in shrimp aquaculture begins with the careful selection and stocking of robust, genetically sound postlarvae (PL). The performance of each crop is largely determined by the genetic foundation, health status, and overall quality of the seed introduced to the pond. With the continued evolution of the shrimp-farming sector, producers now benefit from a wider range of options—genetically improved lines, advanced hatchery and maturation systems, and increasingly sophisticated quality assurance tools.
Modern breeding programs have produced genetic lines that combine rapid growth with enhanced resilience and tolerance to key pathogens. Reputable breeding companies have invested for decades to develop improved lines applying increasingly sophisticated genetic technologies. Broodstock production system technologies are critically important in assuring subsequent hatchery performance. Nevertheless, maintaining genetic integrity throughout the production chain remains a fundamental challenge for ensuring farmer confidence and long-term industry stability. New tools have been developed to differentiate between stocks for better assurance that the farmer is getting the genetic lines requested and to enable identification of operators attempting to shortcut the process by combining F2 stocks of questionable origins.
Hatchery operators today have access to improved biosecurity protocols, refined water quality management, better feed formulations, and high-quality nauplii sources. The introduction of standardized, technology-supported assessments—ranging from morphometric screening to health diagnostics—has further strengthened the decision-making process for PL procurement and stocking.
As Dr. M.S. Swaminathan, widely recognized as the father of India’s Green Revolution, emphasized, “Quality seed is the first step towards a good harvest.” This guiding principle remains equally valid in aquaculture. Although seed costs represent a relatively small share of total production expenses, their influence on survivability, growth performance, and profitability is profound. Investing in the consistent supply and verification of high-quality, genetically improved PL is therefore essential for both economic and environmental resilience in shrimp farming.
