COUNTING FISH IN THE OCEAN; HOW RELIABLE?

NOAA has made a new cod stock assessment"

"The 2008 assessment estimated the offshore cod biomass at 17,672 metric tons. The new assessment estimates the stock at 9,494 metric tons.

Based on the new estimates and modeling, NOAA dropped the hypothetical size of the rebuild stock from 148,084 metric tons to 140,424 metric tons."

Would you believe it? They tell you how many fish there're in the sea to the last tonne. What a precision...
Not 18,000, not 17,600, but exactly 17,672. Wow!!! 
That's how fish stock assessment are assessed: THE MORE PRECISE THE LEAST RELIABLE !!!
