The eye-popping sums raised by land-based aquaculture producers on public markets in the past year is likely to lure even more onto the market, particularly with investors piling into projects that have little to no production, market watchers told IntraFish.

A slew of land-based companies -- six in all -- have taken to the public markets in the past six months alone. In addition, listings for Per Grieg-backed land-based salmon farmer Proximar and land-based sole and turbot farmer Stolt Sea Farm are underway, while other groups, such as US project AquaCon, have said they will pursue IPOs as well.
