Observations on Body Surface Area and Aspect Ratio in Various Species of the Order Syngnathiformes

Abstract

Swimming ability in fish is directly related to body shape, manifesting in various values for swimming speed and body surface area. The constant value used in calculating body surface area derived from length or weight measurements differs between pelagic and benthic species. Furthermore, the aspect ratio is closely related to the feeding pattern, as well as being connected to the swimming speed which is effective in executing escape movements from existing predators in their natural environments. This study presents body surface area and aspect ratio values for nine Syngnathiformes species caught off Turkish coasts. It aims to provide a comparative scientific contribution for members of this order.

Syngnathiformes ordosu türlerinde Vücut yüzey alanı ve Aspect ratio ait bazı tespitler

Öz

Balıklarda yüzme yeteneği vücut şekliyle doğrudan ilişkili olup yüzme hızında ve vücut yüzey alanının belirlenmesinde farklı değerlerle ifade edilmektedir. Vücudun yüzey alanı hesaplanmasında boy yada ağırlığa bağlı sonuçlarla ortaya konarak elde edilen sabit değerin pelajik ve bentik türlere göre farklı olduğu bilinmektedir. Bununla birlikte en-boy oranı besin tüketim şekliyle yakından ilişkili olduğu kadar doğal ortamlarında mevcut avcılarından kaçma hareketini gerçekleştirmede etkin olan yüzme hızıyla da bağlantılıdır. Bu çalışmada Türkiye kıyılarından yakalanan Syngnathiformes ordosuna ait dokuz türe ait bireyde vücut yüzey alanı ve aspact ratio değerlerine ait sonuçlar elde edilmiştir. Bu sonuçlar ordo üyeleri için karşılaştırma niteliğindedir.
