The UK lands an annual average of 1000 tonnes of brown shrimp, but the catch is highly variable between 1500 and 500 tonnes. In the Lancashire fishery for brown shrimp it has been shown that landings in any year are related to the annual catch, average annual air temperature (inverse) and total rainfall in the previous year. That has enabled a good prediction of annual landings one year in advance. Moreover, for the port of Lytham, the abundance of shrimp (annual catch per unit effort) was found to be closely correlated with the mean annual Zurich sunspot number for the period 1965-1975. Given that sunspot numbers are predictable, this provides another tool for the prediction of annual shrimp catch. Sunspot cycle No. 23 (1997-2008) is a good example of the correlation between UK annual brown shrimp catch and mean annual sunspot number.
