A preliminary study on length-weigth relationships for seven elasmobranch species from North Aegean Sea,Turkey

Öz:

Kuzey Ege'de yedi Elasmobranş türünün boy-ağırlık ilişkileri. Bu çalışmada, Kuzey Ege Denizi'nden örneklenen yedi elasmobranş türünün boy-ağırlık ilişkileri incelenmiştir. $WT=a(TL)^b$ , şeklinde ifade edilen denklem her tür için hesaplanmıştır. Bu denklem, Scyliorhinus canicula için, $WT= 0.0016TL^{3.1804}$ ($r^2$ = 0.9795), Mustelus mustelus için, $WT= 0.0008TL^{3.3259}$ ($r^2$ = 0.9745), Squalus acanthias için, $WT=0.0031TL^{3.1056}$ ($r^2$ = 0.9814), Torpedo marmorata için, $WT= 0.0488TL^{2.6935}$ ($r^2$ =0.9584), Raja. clavata için, $WT= 0.0016TL^{3.2914}$ ($r^2$ = 0.9337), Dasyatispastinaca için, $WT= 0.0085TL^{2.9379}$ ($r^2$ = 0.9687) ve Raja miraletus için, $WT= 0.0001TL^{4.0173}$ ($r^2$ = 0.9251) olarak bulunmuştur. Ayrıca bu denklem her iki eşey için de hesaplanmıştır. Türlerin Min., Maks. ve Ortalama boylan ile ağırlıktan tablolar halinde sunulmuştur.

In this study, length-weight relationships of seven elasmobranch species sampled - from North Aegean Sea are examined. An equation expressed as $WT=a(TL)^b$ was calculated for each species. It was calculated as $WT= 0.0016TL^{3.1804}$ ($r^2$ = 0.9795) for Scyliorhinus canicula, $WT= 0.0008TL^{3.3259}$ ($r^2 $ =0.9745) for Mustelus mustelus, $WT=0.0031TL^{3.1056}$ ($r^2$ =0.9814) for Squalus acanthias, $WT= 0.0488TL^{2.6935}$ ($r^2$ = 0.9584) for Torpedo marmorata,$WT= 0.0016TL^{3.2914}$ ($r^2$ = 0.9337) for Raja, clavata, WT= $WT= 0.0085TL^{2.9379}$ ($r^2$ = 0.9687) for Dasyatis pastinaca, and WT= $WT= 0.0001TL^{4.0173}$ ($r^2$ = 0.9251) for Raja miraletus. In addition, this equation was determined for both sexes. Lengths and weights of species (mean, maximum and minimum) were given in tables.
