Ekonomik etkinliğin belirlenmesi: Güney Karadeniz’deki deniz salyangozu (Rapana venosa) avcılığına (balıkçılığına) ilişkin bir çalışma

Öz

Gelişmiş ve gelişmekte olan ülkelerde balıkçı filolarının sayısal ve teknolojik kapasitesindeki kaçınılmaz artış, sınırlı doğal kaynak kapasitesinin yönetimi ve dağıtımı ile balıkçılığın ekolojik ve sosyo-ekonomik sürdürülebilirliği üzerinde önemli etkilere sahiptir. Balıkçılık yönetiminde doğru kararların verilebilmesi için bu etkilerin belirlenmesi önemlidir. Bu çalışma, Türkiye'nin Karadeniz kıyılarında bulunan deniz salyangozu avlayan balıkçıların teknik etkinliği, ölçek etkinliğini ve kapasite kullanımını değerlendirmeyi amaçlamaktadır. Çalışmada ekonomik olarak verimli ve verimsiz tekneler de karşılaştırılmıştır. 452 tekne sahibi ile yüz yüze görüşülerek elde edilen veriler çalışmanın ana verilerini oluşturmaktadır. Teknelerin bir yıllık ekonomik etkinliğini belirlemeye ilişkin veriler toplandı. Ekonomik etkinlik 0,27 ile 1 arasında değişirken, ortalama değer 0,60 olarak bulunmuştur. Tekne sahibinin yaşı, eğitim düzeyi ve balıkçı teknesinin boyunun ekonomik verimliliği olumlu yönde etkilediği sonucuna varılmıştır. Teknelerde teknik etkinlik puanları ekonomik etkinlik puanlarından daha yüksek çıkmıştır. Bu, balıkçıların teknik bilgiden ziyade, veri maliyeti düzeyinde optimum girdi kombinasyonunu seçme konusunda bilgiye ihtiyaç duyduğunu göstermektedir.

Determinants of economic efficiency: A case study of Rapa whelk (Rapana venosa) fisheries in the South Black Sea

Abstract

The inevitable increase in the numerical and technological capacity of fishing fleets in developed and developing countries has major implications for the management and distribution of limited natural resource capacity, as well as the ecological and socio-economic sustainability of fisheries. It is important to determine these effects to make the right decisions in fisheries management. This study aims to assess the fishing capacity, technical efficiency, scale efficiency, and capacity use in a specific subset of Rapa whelk fishers, those in Turkey's Black Sea. Economically efficient and inefficient boats were also compared in the study. The data obtained through face-to-face interviews with 452 boat owners constitute the main data of the study. Data were collected about the economic efficiency of the boats for one year. While economic efficiency ranged between 0.27 and 1, the average value was found to be 0.60. It was concluded that the age of the owner, the education period, and the length of the fishing boat positively affected economic efficiency (p<0.05). In the boats studied, technical efficiency scores were greater than economic efficiency scores. This suggests that rather than technical information, fishers require information on selecting the optimum input combination at the data cost level.
