Erratum to: All fish for China?

Erratum to: AMBIO (2013) 42: 923–936 DOI 10.1007/s13280-013-0448-9

In this communication we give the following erratum for the paper “All fish for China?” Since the Engel curve is formed by plotting the quantity of fish protein intake against the income (measured as constant GPD per capita), with all prices being held constant, income is plotted on the x axis and the quantity of fish protein intake on the y axis. Thus, the correct formulae of Eqs. (1–8) as well as their coefficients of determination (pp. 928–929) are the following:

$$ D_{CH} (x) = - 3 \times 10^{ - 7} x^{2} + 0.0003x + 0.0097 \quad R^{2} = 0.9042 $$

(1’)

$$ D_{RW} (x) = 0.0159x^{0.1842} \quad R^{2} = 0.8707 $$

(2’)

$$ D_{O} (x) = - 3 \times 10^{ - 10} x^{2} + 1 \times 10^{ - 5} x + 0.0059\quad R^{2} = 0.7400 $$

(3’)

$$ D_{NA} (x) = 0.0242x^{{9 \times 10^{ - 5} }} \quad R^{2} = 0.8532 $$

(4’)

$$ D_{LAC} (x) = 0.005x^{0.2868} \quad R^{2} = 0.5295 $$

(5’)

$$ D_{E} (x) = 2 \times 10^{ - 10} x^{2} + 7 \times 10^{ - 7} x + 0.0598\quad R^{2} = 0.5873 $$

(6’)

$$ D_{AS} (x) = - 3 \times 10^{ - 8} x^{2} + 4 \times 10^{ - 5} x + 0.0543\quad R^{2} = 0.6381 $$

(7’)

$$ D_{AF} (x) = 0.029e^{0.0027x} \quad R^{2} = 0.5000 $$

As a result, the correct versions of Figs. 4 and 5 are now the following:
