Abstract



The dataset of the
study consists of total length, fork length, head girth, maximum girth and
weight measurements of 136 bluefish. The relationship between the total length
and fork length of the product was TL=1.1348×FL-0.8184; the relationship between the
total length and weight was W=0.0103×L2.97. The relationships
between the total length and head girth and between the total length and
maximum girth of the sample were linear: the relationship of the total length
and head girth was Ggill=0.5092×TL-0.0874;
the relationship of the total length and maximum girth was Gmax=0.5989×TL-0.8540. The statistical relationship between length
and girth was used to obtain a theoretical gillnet selectivity equation for the
species. In conclusion, a relationship of S(l)=Φ[(C-Ggill)/0.4952]×[1-Φ((C-Gmax)/0.4255)] was
determined between the stretched size of the mesh used in bluefish fishing and
the catch rate. Using this equation, and considering the legal length and
length at first maturity, the minimum mesh size of the gillnet for sustainable
fishery was determined.

Abstract



Çalışmanın veri setini, 136 adet lüfer balığı üzerinde yapılan; total
boy, çatal boy, operkulum çevresi, vücut çevresi ve ağırlık ölçümleri
oluşturmaktadır. Türün total boyu ile çatal boyu arasında TL=1,1348×FL-0,8184, total boyu ile
ağırlığı arasında ise W=0,0103×L2,97 şeklinde bir
ilişki olduğu tespit edilmiştir. Örnekleme ait total boy-operkulum çevresi ve
total boy-vücut çevresi arasında ise sırası ile Ggill=0,5092×TL-0,0874 ve Gmax=0,5989×TL-0,8540 şeklinde doğrusal
bir ilişkinin olduğu hesaplanmıştır. Boy ile çevre arasında kurulan
istatistiksel ilişkiler kullanılarak, türe ait kuramsal uzatma ağı seçicilik
denklemi elde edilmiştir. Sonuç olarak, türün avcılığında kullanılabilecek ağın
tam göz boyu ile yakalanma oranları arasında S(l)=Φ[(C-Ggill)/0,4952]×[1-Φ((C-Gmax)/0,4255)] şeklinde bir
ilişkinin olduğu tespit edilmiştir. Elde edilen bu denklemden faydalanılarak,
türün yasal ve ilk üreme boyları dikkate alınarak, sürdürülebilir bir avcılık için
kullanılacak sade uzatma ağının minimum tam göz boyunun ne olması gerektiği
belirlenmiştir.
