Another interesting effect that can be seen from this result is
that prices increase for the period 2001 to 2007,but since then,
prices have been decreasing . This can be explained by the effect of
the economic crisis on the consumption of a luxury product.
Finally,it can be seen that the port where the red shrimps have
been commercialized also affects their price . Prices vary also by
port, compared to Torredembarra,prices at Port de la Selva are 37% higher (Fig. 5).
