Abstract



Although goatfishes (Mullidae Rafinesque, 1815) are among the most important commercial fishes in Turkey, no research has been found investigating the characteristics and spatial patterns of goatfish fishery. Here, we assessed the goatfish fishery of Turkey based on the microdata set of Turkish National Fishery Statistics gathered by Turkish Statistical Institute (TÜİK) between 2014 and 2017. In this context, we investigated the variation of total goatfish catch by cities. In addition, we compared the contribution of small (boat <10m) and large scale (boat >10m) fishers as well as different fishing techniques to the total goatfish catch in Turkey. Finally, an evaluation was made on the discard rates recorded in the official landing statistics. The results showed that higher red mullet (Mullus barbatus Linnaeus, 1758) catch was reported in the eastern Mediterranean, whereas surmullet (Mullus surmuletus Linnaeus, 1758) catch was significantly higher in the western Black Sea. On the other hand, fishery-independent investigations revealed that the Turkish fishery fleet mostly catches red mullet throughout the coasts of Turkey. Therefore, the separate records of red mullet and surmullet in the landing statistics likely represent the local names of red mullet rather than two different species. Large scale fishers were the main source of fishery pressure in the Mediterranean Sea, the Aegean Sea and the Black Sea. However, the majority of the catch was landed by small scale fishers in the Marmara Sea. The bottom trawl fishery landed 88, 92 and 87% of total goatfish catch in the Black Sea, the Aegean Sea and the Mediterranean Sea, respectively. Purse seiners provided the largest part of total goatfish catch (40%) in the Marmara Sea, where the bottom trawl fishery is prohibited. The overall average for the discard rate was found to be 0.47%. There were no statistically significant differences among the discard rates of two species, marine regions or fishing methods.

Türkiye’deki barbungiller balıkçılığının TÜİK mikro-veri setine dayalı olarak değerlendirilmesi

Abstract



Barbungiller (Mullidae Rafinesque, 1815), Türkiye balıkçılığının en önemli türleri arasında yer almaktadır. Buna karşın, barbungil balıkçılığının genel karakteristik özellikleri ve iller bazında değişimi üzerine geniş ölçekli bir değerlendirme ile karşılaşılmamıştır. Bu çalışma kapsamında Türkiye İstatistik Kurumu (TÜİK) tarafından 2014-2017 yılları için derlenen mikro-veri seti kullanılarak ticari balıkçılık filomuz tarafından gerçekleştirilen barbun (Mullus barbatus Linnaeus, 1758) ve tekir (Mullus surmuletus Linnaeus, 1758) avının şehirlere göre değişimi incelenmiş, küçük (tekne <10m) ve büyük ölçekli (tekne >10m) balıkçılar ile farklı balıkçılık yöntemlerinin toplam ava katkısı karşılaştırılmış ve rapor edilen ıskarta oranları değerlendirilmiştir. Çalışma sonucunda Doğu Akdeniz’de barbun, Batı Karadeniz’de ise tekir balığı avının daha fazla olduğu görülmüştür. Diğer taraftan, literatürde balıkçılıktan bağımsız olarak yapılan araştırmaların sonuçları incelendiğinde Türk balıkçılık filosunun esas olarak barbun avladığı görülmüştür. Dolayısıyla, TÜİK istatistiklerindeki barbun ve tekir kayıtlarının farklı türlerden ziyade yerel isimlendirme farklılıklarını yansıttığına dair güçlü bir şüphe oluşmuştur. Akdeniz, Ege ve Karadeniz’de barbun avının çoğu büyük ölçekli balıkçılar tarafından karşılanırken, Marmara’da küçük ölçekli balıkçıların toplam ava katkısı daha yüksektir. Toplam avın Karadeniz’de %88’i, Ege’de %92’si ve Akdeniz’de %87’si dip trolü avcılığından karşılanmaktadır. Dip trolü avcılığının yasak olduğu Marmara Denizi’nde ise, toplam barbun avının %40’ı gırgır balıkçıları tarafından rapor edilmiştir. Mikro-veri setinde rapor edilen ıskarta oranının türler, denizler ve av araçları arasındaki değişimi istatistik açıdan önemli bulunmamış olup, barbun ve tekirin toplamı için %0,47 olarak hesaplanmıştır.
