Testing for a temperature effect on an early catch record

In conjunction with early climate records, catch records from pre-industrial fisheries are a potentially valuable source of information about the effect of climate on fisheries. This paper describes a test for a temperature effect on an 18th century catch record of Icelandic cod. The results of the test, which is based on a model that incorporates both internal population dynamics and a potential temperature effect, support the existence of a temperature effect.
