Weight-size characterization of Alitta succinea (Leuckart, 1847) distributed in the south-eastern part of the Georgian Black Sea


Author(s): Guranda Makharadze

Abstract: The most dominant specie in Epifauna composition in the south-eastern part of the Georgian Black Sea is Polychetae Alitta succinea (Leuckart, 1847). Samples were collected in three stations–Tsikhisdziri, Green Cape and Kvariati during spring and summer seasons of 2010. The aim of surveys was to identify a correlation between body size and damp weight. Totally 111 examples were used for sampling. Their sizes varied between 4.6-13.5cm and damp weight 0.31-182.5gm. The body length as an average was 7.04 cm. The variance has been 3.45cm, standard deviation was 1.86 and coefficient of variation equaled to 26% and average point of variation; The average indication of an arithmetical absolute uncertainty was 0.18; the average arithmetical relative uncertainty composed of 3% meaning that the precise calculation of average arithmetic was reasonable. The general average was 6.69 ≤μ ≤ 7.39 i.e. being in interval of 6.69 and 7.39; The average damp weight of the body equaled to 0.65gm, the correlation connection between size and weight was stable and accordingly coefficient of correlation equaled to 0.76. Regressive analyze of the body size and weight showed that increasing 1cm of size provoked in average enlarging 0.25gm of weight.
