Morphometric changes in an elasmobranch ( Squalus acanthias ) after preservation

Length, weight, and volume of eggs, embryos, and postembryonic spiny dogfish (Squalus acanthias) up to 83 cm long were differentially affected when frozen or kept in 5% formaldehyde solutions of different salinities. Deviations from measurements in the unpreserved condition were greater with longer...

Description
Summary:Length, weight, and volume of eggs, embryos, and postembryonic spiny dogfish (Squalus acanthias) up to 83 cm long were differentially affected when frozen or kept in 5% formaldehyde solutions of different salinities. Deviations from measurements in the unpreserved condition were greater with longer periods of storage and larger fish size. Morphometric changes were similar to those for teleosts at small sizes, but less at larger sizes.
