Abstract



In this study, it was investigated that changed catch composition
reflected on characteristics of small scale fishing gear in Gökova Bay. For
this purpose technical characteristic of fishing gears, used in cooperative
members of Akyaka, Akçapınar and Akbük, were identified. FAO standardizations
were taken into consideration when technical drawing of fishing gear. The
changes in fishing gears have been presented to be compared with the previous
studies in the same region. In total 11 different nets, 5 gillnet, 5 trammel
net and combine (gill+trammel net), were identifies in the Gökova bay. In
additon, 3 different longline called thin, middle and thick were presented. The
most important changes were found in gillnets. While three type of gillnets,
red mullet, Atlantic bonito and sardine were used before 2005, five different
gillnets, red mullet, pink dentex, yem, air species, Atlantic bonito were
identified. For trammel nets, shrimp and bilidye nettings are no longer used.
There are some differences on technical structures (hanging ratio, length,
height, etc.) of both gill and trammel nets used before and after 2005.
Possible reason for these differences in inhabiting of lessepsian and invasive
species and to begin to exploit them commercially. In such areas where catch
composition changes, similar studies will be repeated at certain times to
contribute to better management of fisheries.

Abstract



Çalışmada, değişen av kompozisyonun Gökova körfezinde kullanılan küçük
ölçekli av araçlarının özelliklerine yansıması araştırılmıştır. Bu amaçla
Akyaka, Akçapınar ve Akbük kooperatifleri üyelerince kullanılan ağların teknik
özellikleri tanımlanmıştır. Balıkçılık takımlarının teknik çizimlerinde FAO
standardizasyonu dikkate alınmıştır.  Av
araçlarındaki değişim, aynı bölgede daha önce yapılan çalışmalar ile
karşılaştırılarak ortaya konmaya çalışılmıştır. Bölgede toplam 11 (5’i galsama
5’i fanyalı ve 1 adedi de kombine) adet farklı uzatma ağı kullanılmaktadır.
Ayrıca ince, orta ve kalın olarak adlandırılan 3 farklı paragat takımı
tanıtılmıştır. En büyük değişimin galsama ağlarında olduğu tespit edilmiştir.
2005 yılı öncesi, palamut, barbunya ve sardalye galsama ağı olmak üzere üç
farklı ağ tanımlanırken, günümüzde barbunya, trança, yem, hava balığı ve
palamut galsama ağı olarak beş farklı tipte ağ tanımlanmıştır. Fanyalı uzatma
ağlarında ise karides ve bilidye ağı artık kullanılmamaktadır.  2005 yılı öncesi ve sonrasında kullanılan
sade ve fanyalı ağların hedef türlerinde ve teknik yapılarında (donam faktörü,
uzunluk, yükseklik) farklılıklar bulunmuştur. Farklılıkların muhtemel sebebi
bölgeye lesepsiyen ve istilacı türlerin yerleşmesi ve bunların ekonomik olarak
yararlanmaya başlanmasıdır. Av kompozisyonunun değiştiği bu tür alanlarda,
benzer çalışmaların belirli dönemlerde tekrarlanarak balıkçılığın daha iyi
yönetilmesine katkı sunacaktır.
