hand-pushed nets. In all UK shrimp fisheries, the catch is first 'riddled' to release the young of shrimps and fish. The shrimps are then traditionally boiled on board before landing. Over of C. crangon were caught in 1999, with Germany and the Netherlands taking over 80% of this total. 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 Zürich 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. Greenpeace Germany classifies the brown shrimp as an "unsustainable" choice that should be avoided. Brown shrimp have been documented to contain microplastics. As food The consumption of brown shrimp is popular in Belgium, the Netherlands, northern Germany, and Denmark. Shrimp in general are known as garnalen in Dutch. It is the basis of the dish tomate-crevettes, where the shrimp are mixed with mayonnaise and fresh parsley, and served in a hollowed-out uncooked tomato. The shrimp croquette is another Belgian speciality; the shrimp are in the interior of the battered croquette along with béchamel sauce. Freshly cooked, unpeeled brown shrimp are often served as a snack accompanying beer, typically a sour ale or Flemish red such as Rodenbach. In Lancashire, England, the peeled brown shrimps are mixed with butter and spices (including mace) to make potted shrimps, a dish traditionally eaten with bread.
