Konieczność zaprojektowania uniwersalnej odgławiarki do ryb słodkowodnych wywołała podjęcie badań morfometrycznych celem określenia optymalnego rodzaju ciecia odgławiającego. Artykuł zawiera wyniki analizy takich badań przeprowadzonych dla karasi, leszczy, płoci i pstrągów.

In Poland and abroad beheading of fresh-water fish is still done by hand. Heading machines used at present in sea fish processing are, for many reasons, useless for fresh-water fish processing. Therefore, there is a need for designing an universal heading machine for fresh-water fish. It requires matching the kind and the line of heading cut for fish of the same species, as well as for fish of various species in a wide range of length, giving high technological efficiency. This choice should be based on the data analyses of morphometric studies. The paper presents the procedure for such an analysis of measured morphometric parameters of crucian, bream, roach, and trout.
