Özet
Su ürünleri avciliginda kullanilan sepetlerin sekli ve agiz konumunun av verimi ve tür kompozisyonu üzerindeki etkisini ele alan bu çalismada, kare ve silindirik sekilli sepetlerde üstten ve yandan olmak üzere iki ayri yöne açilan giris denenmistir. Dört sepetlik iki set ile ayri ayri yapilan paralel denemeler sonucunda 2 yengeç ve 13 balik türünden olusan toplam 1412 birey yakalanmistir. Arastirma süresince en çok 293 birey Labridae ailesi üyeleri avlanirken bunu sirasiyla 160 birey ile Blenniidae ailesi üyeleri ve 148 birey ile Eriphia verrucosa izlemistir. Avlanan su ürünleri içerisinde yöre halki tarafindan besin olarak tüketilen türlerin orani yaklasik %70 civarindadir. Elde edilen sonuçlara göre uygun sekilde tasarlanmis sepetlerin Karadeniz’de pavurya (E. verrucosa), izmarit baligi (Spicara maena), kayabaligi (Gobius spp.), ispari (Diplodus annularis) ve eskine (Sciaena umbra) avciliginda kullanilabilecegi 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 from two different entrance position were tried. 1412 individuals of 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 (E. verrucosa), pickerel (Spicara maena), gobies (Gobius spp.), annular seabream (Diplodus annularis) and brown meagre (Sciaena umbra).
