Promising to tell you the Prawn, the whole Prawn and nothing but the Prawn…….here I shine a light on global shrimp aquaculture and downstream markets……for those looking in from outside and those inside interested in the wider outside. Food trends, intelligence, tech, regulatory, investment and some fun, way out, or even wacky, shrimp material….
About facts and myths…..’The original shrimp stock was obtained using rigorous screening of captured wild shrimp for selection of individuals naturally free of major shrimp pathogens.”
Original shrimp stock were cultured PLs and supplied by Prawnmaster to Dr Lightner at APL, Arizona in 1989 from his facility in Mexico.
They were 16,000 PL’s spawned from artificially inseminated vannamei in Mexico and passed through a proprietary natural selection program on a special diet and an extremely low survival rate.
These were declared SPF by APL (personal communications and visits) and sent to OI in Hawaii. The female Griselda became famous.
There is only one country in the world that had the stranglehold on live global shrimp movements under the UN OIE and that is the USA. A country where Pacific vannamei is not even endemic.
This has led to the manipulation of trade and the promotion of US interests in specific shrimp pathogen programs. USA is not even a shrimp producer – even though that was stated aim or the US NMFS Shrimp Consortium’s program back in the late 1980’s.
Ecuador was the first country that US targeted for its genetics program and it failed miserably. Ecuador has since gone on to develop a more sensible program – with increased resulting production – whereas USA has still zero real shrimp farming.
Number of epidemics and pandemics so far – well if you believe TSV was one, WSSV is another, IHHNV a further, Yellowhead in there and IMNV added on that is 5 between 1983 and 2003 alone. Anecdotal information here
Many others afflictions arise at regional and local levels linked to specific poor husbandry also.
