In this study, it was aimed to analyses some growth parameters of the invasive Diadema setosum (Leske, 1778) from Iskenderun Bay. For this reason, a total of 117 samples were collected in September 2021 from rocky shores coast of Iskenderun. The test diameter in D. setosum was varied between 24.32 and 81.1 mm with an average of 51.8±1.18 mm in length. The total weight was changed between 27.14 and 185.11 g, and the average total weight was 84.64±2.77 g. The length-weight relationship of D. setosum was W = 0.7917*L1.1773. The value of regression co-efficient (R2) estimated for the species was 0.71. Gonadosomatic indexes (GSI) was determined as 3.4±0.04%, 8.91±0.09%, and 7.50±0.14%, in GSI1, GSI2, and GSI3, respectively. This study is the first detailed study on the length-weight relationships (LWRs), length-weight frequency and gonadosomatic indexes of the invasive sea urchin (D. setosum) from İskenderun Bay, Northeastern Mediterranean.
This study is a part of PhD thesis of the first author, which was carried out under the supervision of second author. Thanks to the Scientific & Technological Research Council of Turkey (TUBITAK-2211/C National PhD Scholarship Program for Priority Areas) and Council of Higher Education for 100/2000 PhD scholarship program for support.
Bu çalışmada, İskenderun Körfezi kıyılarındaki istilacı Diadema setosum türünün (Leske, 1778) bazı biyolojik parametrelerinin incelenmesi amaçlanmıştır. Bu nedenle, Eylül 2021'de İskenderun'un kayalık sahil kıyılarından toplam 117 örnek toplanmıştır. D. setosum türünün testa (kabuk) çapı 24.32 ile 81.1 mm arasında ve ortalama 51.8±1.18 mm olduğu belirlenmiştir. Örneklerin toplam ağırlığı 27.14 ile 185.11 g arasında değişmiş olup, ortalama 84.64±2.77 g hesaplanmıştır. D. setosum türünün boy-ağırlık ilişkisi W = 0.7917*L1.1773 şeklinde bulunmuştur. Tür için tahmin edilen regresyon katsayısı (R2) değeri 0,71'dir. Denizkestanesi türünün farklı gonadosomatik indeks değerleri (GSİ) GSI1, GSI2 ve GSI3 sırasıyla %3.4±0.04, %8.91±0.09 ve %7.50±0.14 olarak belirlenmiştir. Bu çalışma, İskenderun Körfezi'nde dağılım gösteren istilacı denizkestanesinin (D. setosum) boy-ağırlık ilişkisi (LWR), boy-ağırlık frekansı ve farklı gonadosomatik indeks değerlerini kapsayan ilk detaylı çalışmadır
