Nematodes in mackerel

Description

Data to examine if cooling right after catching prevents nematodes (roundworms) from moving from the belly of mackerel to the fillet. A total of 150 mackerels were investigated and their length, number of nematodes in the belly, and time before counting the nematodes in the fillet were registered. The response variable is binary: presence or absence of nematodes in the fillet.
