Özet
Su ürünleri avcılığında kullanılan sepetlerin şekli ve ağız konumunun av verimi ve tür kompozisyonu üzerindeki etkisini ele alan bu çalışmada, kare ve silindirik şekilli sepetlerde üstten ve yandan olmak üzere iki ayrı yöne açılan giriş denenmiştir. Dört sepetlik iki set ile ayrı ayrı yapılan paralel denemeler sonucunda 2 yengeç ve 13 balık türünden oluşan toplam 1412 birey yakalanmıştır. Araştırma süresince en çok 293 birey Labridae ailesi üyeleri avlanırken bunu sırasıyla 160 birey ile Blenniidae ailesi üyeleri ve 148 birey ile Eriphia verrucosa izlemiştir. Avlanan su ürünleri içerisinde yöre halkı tarafından besin olarak tüketilen türlerin oranı yaklaşık %70 civarındadır. Elde edilen sonuçlara göre uygun şekilde tasarlanmış sepetlerin Karadeniz'de pavurya (Eriphia verrucosa), izmarit balığı (Spicara maena), kayabalığı (Gobius spp.), isparoz (Diplodus annularis) ve eşkine (Sciaena umbra) avcılığında kullanılabileceği söylenebilir.
In this study, the effects of pot shape and position of entrance on fishing efficiency and species compositions is discussed by square and cylindrical shaped pots with two different entrance positions were tried. 1412 individuals from two crabs and 13 fish species were caught in parallel trials, by performed two pot sets. 293 individuals were caught by members of the Labridae family. During the research while the largest number of catch with 293 individuals consist from members of the Labridae family, this was followed by the Eriphia verrucosa with 148 individuals and Blenniidae family members with 160 individuals respectively. The proportion of species consumed as food by the local consumer is around 70% of total catch. According to results of research it can be said that; These fishing pots can be used to trapping in Black Sea coasts for crab and some fish like warty crab, pickerel (Spicara maena), gobies (Gobius spp.), annular seabream (Diplodus annularis) and brown meagre (Sciaena umbra).
