Growth and reproduction of blotched picarel (Spicara maena Linnaeus, 1758) in the central Aegean Sea, Turkey

Öz:
İzmarit balığının (Spicara maena Linnaeus, 1758) büyüme ve üreme özellikleri, Temmuz 2004 ve Haziran 2007 tarihleri arasında orta Ege Denizi’nden elde edilen bireylerle (n = 2547) tespit edilmiştir. Örneklerin; % 71,9’unu dişi, % 16,2’sını erkek ve % 11,9’unun ise eşeysel olgunluğa erişmemiş bireylerden oluştuğu tespit edilmiştir. Stoğun dişi:erkek oranı 1:0,23 olarak hesaplanmıştır. Boy-ağırlık ilişkisi tüm bireyler içinW= 0,011$L^ {3.02}$, dişiler içinW= 0,011$L^ {3.00}$, erkekler için W = 0,011$L^ {2.99}$ olarak tespit edilmiştir. Her iki cinsiyet ve tüm bireyler izometrik büyüme göstermişlerdir. Yaştaki ortalama boy temeline dayanan von Bertalanffy büyüme eşitliği parametreleri, $L _infty$ = 21,99 cm, k = 0,255 $y^ {-1}$, $t _o$ = -1,165 y ve bireyin sonsuzda ulaşabileceği ağırlık ($W _infty$) 123,35 g olarak hesaplanmıştır. İlk olgunluk boyu erkeklerde 8,1 ve dişilerde 8,5 cm’de tespit edilmiştir. Diğer taraftan ilk üreme boyunun dişilerde 11,51, erkeklerde 13,12 cm’de olduğu ve her ikisinin de 2 yaşa karşılık geldiği saptanmıştır. Yumurtlamanın Mart ve Haziran ayları arasında gerçekleştiği belirlenmiştir.

Growth and reproduction of the blotched picarel, Spicara maena (Linnaeus, 1758), were determined based on specimens (n = 2547) collected from the central Aegean Sea between July 2004 and June 2007. The samples consisted of 71.9% females, 16.2% males, and 11.9% immature individuals. The sex ratio of females to males was 1:0.23. The lengthweight relationship was W = 0.011$L^ {3.02}$, W = 0.011$L^ {3.00}$, and W = 0.011$L^ {2.99}$ for the combined sexes, females, and males, respectively. For all samples and both sexes the length-weight relationship showed isometric growth. The von Bertalanffy growth equation was fitted on the basis of mean length-at-age data, resulting in parameter values of $L _infty$ = 21.99 cm, k = 0.255 yea$r^ {-1}$, and $t _o$ = -1.165 year, and weight at infinity ($W _infty$) was calculated as 123.35 g. Length at first maturity was 8.1 cm in males and 8.5 cm in females. On the other hand, first reproduction length was 11.51 cm and 13.12 cm for females and males, respectively, both corresponding to 2 years of age. It was observed that spawning occurred between March and June.
