| Title : | VARIABILITY OF LENGTH WEIGHT RELATIONSHIP AND CONDITION FACTOR OF THE EUROPEAN EEL (Anguilla anguilla L.) – CASE STUDY FROM THE LAKE SKADAR (MONTENEGRO) |
| Abstract : | The results presented contribute to the knowledge about the length-weight relationships (LWR) of the European eel (Anguilla anguilla). When using the results presented in this study, it should borne in mind that the samples were taken during the year and the number of fish examined was relatively large. LWRs parameters are calculated for the two different length classis and found significant. In the present study, bigger specimens (45 cm) of European eel have value of growth coefficient b = 3.25. This value is significantly higher than the b = 3 showing that weight of this fish increases more than cube of its length (positive growth coeffient). The lesser specimens (<45 cm) of European eel have value of growth coefficient b = 2.54, and this value is significantly smaler than the b = 3. The relationship between total length (TL) and weight (W) was described by the equation: The values of condition factor (CF) were ranged from 0.13-0.25 (average 17.0-18.5) and smalest were found in the December. Analysis of the total sample, of any species, cannot show by what rule the population grows, if infrapopulation variability is present, because the studied value will depend on the number of individual subgroups. The estimations of LWRs shall be helpful in future works on by catch of fish species in Skadar Lake in Montenegro and Albania. |
