Estimation of Exploitable Sprat (Sprattus sprattus, Linnaeus, 1758) Biomass along Black Sea Coasts of Turkey (Samsun Region): This Paper is Dedicated to the Memory of Sedat GÖNENER

Abstract

In this study, exploitable stock biomass of sprat (Sprattus sprattus, Linnaeus, 1758) distributed along Samsun shelf area (SSA) was estimated for the period 2014 January – May. “Swept Area” method was used in the study. Catch per unit area (CPUA) and stock biomass of sprat in the SSA in size 2508.395 km2 were estimated for deeper and shallower waters than 40 meters which were accepted as the midpoint. Accordingly, CPUA values were determined as; 40018.76 ± 10852.61 kg/km2 in shallower area than 40 meters, 27758.77 ± 4.242.07 kg/km2 in deeper area than 40 meters and 33602 ± 6017.46 kg/km2 for SSA. The exploitable stock size of sprat was estimated as 84287 ± 15094 tons in SSA. Average length values of sampled sprats were 7.08 ± 0.02 and it was determined that 7-7.4 cm is the densest size group in the distribution of length-frequency. The other hand, length frequency distribution with respect to depth, densest size groups as follows; 7 – 7.4 cm for shallower waters than 40 meters, 6.5 – 6.9 cm for deeper waters than 40 meters.

Thanks

This paper is dedicated to the memory of Sedat Gönener (gone but never forgotten) who supervised the master thesis that is the basis of this work. We also kindly thank to Cemal MALKOÇ and “Malkoçoğlu Fisheries Comp.” for providing generous contributes to the study.
