Ann: Clean Seas Q3 Sales Revenue increases 24% over prior year, page-5

CSS is no different to any other business that has to invest in working capital to grow especially in early stages, the only difference is that it takes up to 2 years to 'buy' their inventory.
The biomass has been growing a lot faster than sales in recent periods reflecting not only the 18 month-2 years to grow fish but also for the anticipated sales uplift.
As noted in the commentary CSS has the flexibility to change it's investment in biomass, ie they don't need to keep investing cash at such a high level to continue their strategy, especially with their Sensory Fresh frozen range.
Personally i would prefer them to continue on their 'aggressive' strategy using debt than wait an extra year or two to get to the same point.

On another note i think they are now being conservative with the sales estimate.
