Lüfer Balığı’nın (Pomatomus saltatrix L., 1766) Av Kompozisyonu, Gonadosomatik İndeks ve Kondisyon Faktörü
Öz
Bu çalışmada, Eylül 2012 ile Ağustos 2013 tarihleri
arasında Marmara Denizi ve Karadeniz’de ticari balıkçılar tarafından
yakalanan lüfer balıklarının av kompozisyonu, cinsiyet oranı, gonadosomatik
indeks ve kondisyon faktörü incelenmiştir. Çalışmada 353 dişi (%52,53) ve 319
erkek (%47,47) olmak üzere toplam 672 adet lüfer balığı örneklenmiştir. Örneklenen
lüfer balıklarının 12,9 ile 26,3 cm arasında dağılım gösterdiği ve 15-18 cm boy
aralığında yoğunluk gösterdiği tespit edilmiştir. Boy-ağırlık ilişkisi dişi
balıklar için W = 0,0102L2,983 (r=0,977),
erkekler
için W= 0,0105L2,974 (r=0,976)
ve tüm bireyler için W
= 0,0104L2,978 (r=0,977)
şeklinde
hesaplanmıştır. Balığın
içinde bulunduğu koşullara göre şeklini gösteren üssel “b” değeri, dişi, erkek
ve genel olarak 3’den küçük bulunmuş, bütün eşeylerde büyümenin negatif
allometrik olduğu tespit edilmiştir. GSİ değerlerinin
aylık değişimleri incelendiğinde, lüfer balığının üremesi Mayıs ile Ağustos ayları
arasında gerçekleştiği belirlenmiştir. Ortalama Kondisyon faktörü dişiler için
0,976±0,0139, erkekler için 0,971±0,0137 ve tüm bireyler için ise 0,973±0,0136
olarak hesaplanmıştır.
Bu çalışmada elde edilen lüfer
bireylerinin %65,5’inin ülkemizdeki ticari su
ürünleri avcılığının düzenlenmesi
hakkındaki tebliğde belirlenen asgari avlanabilir boy olan 18
cm’nin altında olduğu tespit edilmiştir.

Catch composition, Gonadosomatic Index and Condition Factor of Bluefish (Pomatomus saltatrix L., 1766)
Öz
In this study, catch composition, sex ratio,
gonadosomatic index and condition factor of bluefish caught by commercial
fishers in the Sea of Marmara and the Black Sea, between September 2012 and
August 2013, were investigated. A total of 672 bluefish individuals consisting
of 353 females (52.53%) and 319 males (47.47%) were sampled throughout the
study. The total length of bluefish samples varied from 12.9 cm to 26.3 cm and it
was determined that individuals between the length range of 15-18 cm dominated
the catch composition. The length-weight relationships for females, males, and
for overall individuals were calculated as W = 0.0102TL2.983 (r =
0.977), W = 0.0105TL2.974 (r = 0.976) and W = 0.0104TL2.978
(r = 0.977), respectively. The value of exponential coefficient b, that
indicates the body shape of fish depending on where it lives, was found less
than 3 for females, males, and overall individuals, therefore a negative
allometric growth was determined for both sexes and overall individuals. According
to monthly variations in the mean GSI values, it was determined that the
reproduction period of bluefish was determined to be between May and August.
The mean condition factor was calculated as 0.976 ± 0.0139 for females, 0.971 ±
0.0137 for males and 0.973 ± 0.0136 for overall individuals, respectively.
It was
determined that 65.5% of the bluefish samples examined in this study were below
the minimum landing size of 18 cm, which was specified in the communiqué on the
regulation of commercial fisheries in Turkey.
