China

Freshwater Prawn Production, Correction

 

Shrimp News: There was a mistake in a recent report I posted to this site on freshwater prawn farming in China.  I assumed that the author of the article was writing about all freshwater prawn farming in China, when, in fact, he was just writing about the giant freshwater prawn, Macrobrachium rosenbergii.

 

Michael New, the world’s leading expert on prawn farming, pointed out the error:

 

“....I have determined that the author makes it clear that he is only talking about the giant river prawn M. rosenbergii and does not describe the farming of the indigenous species, the oriental river prawn M. nipponense.  I therefore have no problem with his article in World Aquaculture, except to note that his production data are three years out of date.”

 

“However, I do have an issue with the introduction that you yourself wrote on the page on freshwater prawn farming on your website, where you stated ‘China is the leading producer of farmed prawns in the world, with production approaching 150,000 metric tons a year in 2009....’  Your statement is wrong as it leads the reader to assume that the article concerns all species of freshwater prawns and that 150,000 metric tons was therefore the total production.  This is not so.  In fact, the production of M. nipponense is much greater, so the overall total is considerable.”

 

“The actual current (most recently available from FAO) data are as follows:”

 

Chinese Production and Farm-Gate Value of Freshwater Prawns in 2012

 

Giant river prawn (M. rosenbergii): 124,713 metric tons valued at $593,633,900.

 

Oriental river prawn (M. nipponense): 237,431 metric tons valued at $1,130,171,700.

 

Total freshwater prawn production: 362,144 metric tons valued at $1,723,805,500.
