Length-weight and length-length relationships of Red Scorpionfish (Scorpaena scrofa L. 1758) from Aegean Sea (Turkey)

Abstract

In this study, the length-weight and length-length relationships were investigated for S. scrofa from İzmir Bay, Aegean Sea. All fish sample lengths and weights were recorded to the nearest 0.01 cm and to 0.01 g. The measured total length values for females, males and combined sexes were 16-30.2 cm; 17.7-28 cm and 16-30.2 cm respectively. The weight values for females, males and combined sexes were 73.20-441 g; 89.80-378 g and 73.20-441 g respectively. According to t test results, there were no statistically significant differences for S. scrofa species (P˃0.05); therefore, female and male samples were evaluated together. The length-weight relationship equations as y=0.016x^2.993(r²=0.914) for all specimens. The ‘b’ value of  LWR was not significantly different from 3.0 and their growth type was isometric. Total length-standard length relationship equations were determined as y=1.287x+0.112 (r²=0.97). This study is helpful in providing information about length-weight and length-length relationships and the current study can be useful to compare stocks of the species in the different habitats.

Ege Denizi’nden (Türkiye) Lipsoz (Scorpaena scrofa L. 1758)’un Boy-Ağırlık ve Boy-Boy İlişkisi

Abstract

Bu çalışmada, Ege Denizi İzmir Körfezi’nden S. scrofa’nın Boy-Ağırlık ve Boy-Boy ilişkisi incelenmiştir. Tüm örneklerin boyları ve ağırlıkları 0.01cm ve 0.01 g hassasiyetle ölçülmüştür. Dişi, erkek ve tüm bireylerde ölçülen total boy değerleri sırasıyla 16-30.2 cm; 17.7-28 cm ve16-30.2 cm’dir. Ağırlık değerleri ise 73.20-441 g; 89.80-378 g and 73.20-441 g’dır. S. scrofa  türü için, t-test sonuçlarına göre önemli bir farklılık olmadığından dişi ve erkek örnekler birlikte değerlendirilmiştir. Tüm bireyler için boy-ağırlık ilişki denklemi y=0.016x^2.993(r²=0.914) olarak hesaplanmıştır. Boy-Ağırlık ilişkisinin ‘b’ değeri, 3’den önemli derecede farklı değildir, ve türün büyümesi izometriktir. Total boy standart boy ilişki denklemi y=1.287x+0.112 (r²=0.97) olarak belirlenmiştir. Bu çalışma, boy-ağırlık ve boy-boy ilişkileri hakkında bilgi sağlamada faydalıdır ve mevcut çalışma, türlerin farklı habitatlardaki stoklarını karşılaştırmak için kullanışlı olabilir.
