Abstract

Morphological characteristic of lumpfish caught in the spring of 1995 in coastal waters of the Southern Baltic Sea near Unieście and Chłopy have been outlined in this paper. In total 140 fish were used for measurements. The analysis of countable features of fish revealed that the number of fin rays was as follows: D2 10-11; A 9-11; P 18-24. Also tubercles arranged in three rows situated on body sides were counted. Characteristics of 19 morphometric features have been set out; 17 features were described with indices expressed as percentage of the standard length. Sexual dimorphism refers to the head and fin dimensions.
