Our story
A manufacturer, not a trading company
SIGMA Aquaculture was founded in 2015 as a major brand of SIGMA INDUSTRIES CO.,LTD, committed to aquaculture equipment processing and manufacturing.
Our plant covers around 5,000 square meters and runs two core production lines: welding of PVC fish tanks and HDPE film production. Because tanks and liners come off our own lines, we control quality, lead time and price at the source.
Our engineers bring more than 15 years of experience in the aquaculture industry, especially with tilapia and shrimp — so every tank we ship is backed by people who understand fish farming, not just fabrication.
