Abstract

Most of the species migrating to the Mediterranean Sea as a result of the Lessepsian migration have been forming a sustainable population. In this study, population composition, growth, and fisheries of Nemipterus randalli Russell, 1986, an Indo-Pacific fish and live in Antalya Gulf, North-East Mediterranean Sea, were analyzed. The monthly samples were collected (N = 1715) by using experimental bottom trawl. The fish size ranges between 3.9 and 23.8 cm in total length, 0.73 and 171.78 g in weight, males are larger than females, and the length-weight relation was estimated as W = 0.0173 × TL 2.8584. The male and female ratio was calculated as 1:1.402, females are predominant in the population. The average condition factor fluctuated seasonally and ranged between 1.089 and 1.346. Five age groups were identified in the population; Von Bertalanffy Growth Equation was estimated as Lt = 32.56 [1-e -0.20 (t+1.75)]. The size, sex, and age composition show that it established a sustainable population in Antalya Gulf, grows well, reproduce and to be an item of bottom trawl fisheries, and sold in small percentages.

Antalya Körfezi (Türkiye, Akdeniz) Nemipterus randalli Russell, 1986 Poulasyonunun Kompozisyonu, Büyümesi ve Balıkçılığı

Abstract

Lessepsiyen göçü sonucu Akdeniz'e göç eden türlerin çoğu sürdürülebilir bir populasyon oluşturmaktadır. Bu çalışmada, Kuzey-Doğu Akdeniz'in Antalya Körfezi'nde yaşayan ve Hint-Pasifik balıklarından Nemipterus randalli' Russell, 1986 popülasyon kompozisyonu, büyümesi ve balıkçılığı incelenmiştir. İncelenen örnekler (n = 1715) dip trolü ile, aylık olarak toplanmıştır. Yakalanan balıkların boyları (TL); 3,9-23,8 cm, Ağırlıkları ise (TW); 0,73-171,78 g arasında değişmektedir. Erkeklerin, dişilerden daha büyük olduğu görülmüştür. Boy-ağırlık ilişkisi W = 0,0173 × TL 2,8584 olarak hesaplanmıştır. 1: 1,402, dişiler oransal olarak popülasyonda daha baskındır. Ortalama kondiyon faktörü mevsimsel olarak 1,089-1,346 arasında dalgalanma göstermiştir. Popülasyonda beş yaş grubu tespit edilmiştir. Von Bertalanffy Büyüme Eşitliği Lt = 32,56 [1-e -0,20 (t+1,75)] olarak hesaplanmıştır. Büyüklük, cinsiyet ve yaş kompozisyonlarına bakıldığında türün Antalya Körfezi'nde sürdürülebilir bir popülasyon oluşturduğu, iyi büyüdüğü ve ürediği; düşük oranlarda dip trol balıkçılığı tarafından avlandığı ve pazarlandığı görülmektedir.
