LENGTH-WEIGHT RELATIONSHIPS OF FISH SPECIES IN MARMARA LAKE, WEST ANATOLIA, TURKEY
2015, 73 (1) p. 30-32
Abstract
The study reports length–weight relationships (LWRs) for 13 (Atherina boyeri, Cobitis fahirae, Alburnus battalgilae, Cyprinus carpio, Carassius gibelio, Ladigesocypris mermere, Pseudorasbora parva, Petroleuciscus smyrnaeus, Rhodeus amarus, Vimba vimba, Sander lucioperca, Gambusia affinis, Knipowitschia mermere) fish species of 6 families in Marmara Lake, which is an alluvial set lake in west Anatolia, Turkey. Fish specimens were caught between March 2012 and February 2013 with trammel nets and gillnets. The length–weight relationship was calculated using the expression: log (W) = log (a) + b log (L). Parameters of LWR are computed as “a” ranging from 0.0053 to 0.0385, “b” from 2.346 to 3.429, and “r2” from 0.814 to 0.994. Growth type were determined to be isometric, positive allometric and negative allometric for 4, 4 and 5 species respectively. In addition, the present study includes first records of LWR for two endemic and two native species in freshwater of Turkey. The results would be useful for the protection of the presence of endemic species and sustainable fisheries in the lake.
