Introduction
In October 2025, researchers and industry experts visited key shrimp-producing regions of India, including Gujarat and Andhra Pradesh, to assess the ongoing revival of black tiger shrimp (Penaeus monodon) farming. After years of dominance by Pacific white shrimp (Litopenaeus vannamei), the black tiger sector in India has shown renewed dynamism as producers adopt specific pathogen-free (SPF) genetics and invest in breeding infrastructure. This article summarizes the observations and developments gathered from field visits, industry discussions, and market data.
Two Pillars of Broodstock and Post-Larvae Supply
India’s re-emergence in P. monodon farming is currently supported by two main supply models for broodstock and post-larvae (PL):
Unima’s Open Partnership Model
Unima supplies P. monodon broodstock from Madagascar through its subsidiary Aquacultura de la Mahajamba, authorized for export to India. Unima works with around 13 partner hatcheries along India’s East Coast. Its post-larvae are distributed widely under the Unibio brand, giving farmers across both coasts access to SPF P. monodon genetic lines.
Vaishnavi Aquatech’s Integrated Closed Model
Vaishnavi Aquatech, based in Surat, Gujarat, imports Parent Post-Larvae (PPL) from Moana Technologies (Hawaii) to its own Broodstock Multiplication Center (BMC) in Bharuch. There the PPL are reared to adult broodstock and then used to supply the company’s own hatcheries. This integrated model allows control of both broodstock and PL distribution for its hatcheries in Andhra Pradesh and Gujarat.
Alternative sources — such as the government-run Rajiv Gandhi Centre for Aquaculture (RGCA) and potential future imports from Thailand’s genetics suppliers — have yet to make significant commercial impact. As a result, most of India’s P. monodon supply currently depends on Unima and Vaishnavi Aquatech.
Understanding the Broodstock Multiplication Center (BMC)
In the Indian context, a BMC does not multiply broodstock through breeding cycles; rather, it receives Parent Post-Larvae (PPL) from overseas partners and raises them into broodstock. These broodstock are then distributed to hatcheries, which use them to produce PL for farmers. Having a BMC within India simplifies logistics, as shipping PPL is less demanding than transporting live adult broodstock.
Vaishnavi Aquatech’s BMC in Gujarat is one of the largest facilities of its kind in Asia. It features advanced water treatment, staged grow-out sections, and capability to rear tens of thousands of breeders for distribution ahead of the stocking season.
Genetic Performance and Market Supply
Two distinct sources of SPF P. monodon genetics are now active in India:
- Unima/Unibio genetics are regarded as more robust with slightly higher survivability.
- Vaishnavi Aquatech’s genetics tend to grow faster, reaching market sizes sooner under typical stocking densities.
Farmers selecting between the two often choose based on production strategy — either faster cycles for premium sizes or higher survival for reliable yields.
In 2025, India’s P. monodon PL market totaled roughly 2.7–2.8 billion PL, with Unima/Unibio and partners holding around 70 % market share, while Vaishnavi Aquatech contributed the remainder
Farming Practices and Production Trends
Black tiger shrimp grow more slowly than Pacific white shrimp but are easier to raise to larger sizes — a factor that appeals to producers targeting premium markets. Traditional farming cycles involve stocking ponds at lower densities and harvesting large shrimp within 120–180 days, depending on genetic line and strategy.
In Andhra Pradesh and Gujarat, farms are experimenting with hybrid strategies that combine partial harvests at intermediate sizes and full harvests at larger counts. As farmers gain experience with P. monodon genetics, production practices continue to evolve.
Exports and Market Development
Export data from 2021 to 2025 show that India’s P. monodon shipments initially trailed earlier years due to delayed stocking cycles but rebounded strongly from mid-2025 onward. Major destinations now include China, the EU, and the U.S., with China emerging as a key and fast-growing market.
India’s exporters aim to diversify beyond tariff-constrained U.S. markets, with the European Union and Asian destinations playing increasingly important roles. Producers recognize that meeting specific size preferences and certification standards — such as ASC for EU retail — will be key to broader market acceptance.
The Future of India’s Black Tiger Sector
India’s black tiger shrimp sector is still developing. Production remains concentrated in states like Gujarat and Andhra Pradesh, where farming practices, water conditions, and logistics are favorable. With modest production volumes relative to vannamei, the species currently represents a niche but highly valued product.
Stakeholders have mixed expectations for the pace of growth. Some foresee moderate expansion over the next 3–5 years, while others believe structural improvements in genetics, logistics, and market access could accelerate revival. Strategic coordination across the value chain — from broodstock supply and hatcheries to exporters and market promotion — will be critical for scaling India’s P. monodon output sustainably.
Conclusion
India’s black tiger shrimp revival is characterized by renewed investment in SPF genetics, expanded breeding infrastructure, and evolving farming techniques. Although still behind Pacific white shrimp in overall volumes, the black tiger segment is gaining momentum and positioning itself for growth in premium export markets. Continued innovation and market development remain essential for the species to realize its full potential in global trade
