About Us

SeaStock creates global marine science solutions to produce and extract compounds derived from seaweed and algae.

SeaStock products are targeted across the agriculture, cosmetic and pharmaceutical industries. We work with industries and businesses with an identified need for sustainably sourced, naturally derived raw materials.

SeaStock aims to lead in the development of production and extraction techniques of seaweed and algae-based compounds for commercial application.

Company Overview

SeaStock is the leading producer and processor of certified Asparagopsis in Western Australia for supply to global growing markets.

CSRIO researchers have found that a diet containing 0.2% Asparagopsis reduces bovine methane by 98%.

Additionally it has been found that the animal may experience more weight gain from less feed when fed Asparagopsis.

The study showed potential of a 20% growth rate enhancement during 90 day feeding period as methane generation for the animal is energy intensive.

The company has developed a unique and differentiated business model supported by the leading research team at SA-based Flinders University in order to develop cultivation and value adding IP to supply established long term off take partners domestically and internationally.
