The other day Prawnmaster put up a post response on LI that the pursuit of RAS larviculture was currently a commercially flawed approach – vannamei larviculture being flow through Galveston – unless the output seed price makes it all worthwhile.
High PL price notwithstanding will hamper growth – unless that price is able to be passed on.
…and why technically make your life harder, with relatively small requirements – due to the density (numbers/litre) – shrimp larviculture facilities are placed conveniently next to high quality seawater sources.
In maturation RAS works extremely well.
In larviculture commercially no-one yet has broken through really in RAS because not really necessary.
Prawnmaster noted that there were probably 5-6 people in Europe who are pursuing RAS in larviculture.
Imagine my surprise when one, whom I considered an advanced player from middle Europe, sent this “anyone who have a reliable RAS hatchery is bullshitting. At least at this moment. It’s true, that is what I am working on, but I am long way from getting right…”
Is it possible that the imported larviculture technology (Galveston/Ecuador) is not correct for inland vannamei RAS?
Actually took Prawmaster back to larviculture in Taiwan – for monodon but also developed at same time.
The Taiwanese larviculture practice of doing Zero water exchange until PL2…
Modified Europe technology.
