Built around aquaculture knowledge
A Bangladesh-based aquaculture supply company led by founder and CEO Mostafa Asadullah Chowdhury.
The Eureka Marketing Co. is a Bangladesh-based aquaculture supply company led by founder and CEO Mostafa Asadullah Chowdhury.
Since 2001, we have supported hatcheries and fish farmers across Bangladesh by importing and distributing machinery, industrial aerators, water-testing technology, and chemical reagents — while maintaining a long-standing connection to the Halda River, South Asia's largest tidal carp breeding ground. Our work spans seedling distribution, social awareness, and national heritage projects.
The company's work spans commercial hatcheries, institutional fisheries operations, field-level technical consultation, and international collaborations, reflecting decades of hands-on experience in Bangladesh's aquaculture sector. We specialize in facilitating the import of high-quality brood fish (parent stock) for fry production in fish hatcheries.

Connecting modern technology with our country
We have maintained a coherent relationship with global aquaculture, connecting modern technology with our country. To ensure superior genetic resources and technical support, we maintain close collaboration with multiple institutions including:
- Institute of Aquaculture, Singapore
- The Freshwater Aquaculture Center of Central Luzon State University
- The Aquaculture Center of the Asian Institute of Technology
...and several other distinguished hatcheries and aquaculture institutions throughout South and Southeast Asia.
