Morphometric Aspects and Growth Parameters of the Wedge Clam (Donax trunculus) of the Black Sea, Turkey
Abstract
Donax trunculus, known as wedge clam, is an
Atlantic-Mediterranean bivalve colonizing in fine sand beaches of the upper
subtidal zone. Aim of this study is to determine the biometric features of
wedge clam in sandy beaches, where they live in high-density, and the
relationships between these features.
The samples were collected for between March 2014-February 2015 from an
unexploited population from Black Sea. A
total of 11045 samples were collected during this study. The shell length,
shell width, shell thickness and shell weight, total weight and meat weight
were measured. SL changes between 4.5 and 35.5 mm with an average value of 18.6
± 8.5 mm. Average TW of the total sampling group was 1.2 ± 1.1 g
(0.007-4.64). Relationships between SL and SWe, SWi and SWe, ST and SWe were
found as SWe=0.0001 SL2.9659 (R2=0.98), SWe=0.0002SWi3.3938
(R2=0.97) and SWe=0.0072ST2.6968 (R2=0.89),
respectively. Average MW of wedge clam was calculated as 0.2 ± 0.2 g
(0.001-2.74). The relationships between growth parameters were detailed by
cluster analyses (CA), correlation analyses and comparison analyses. Results of
this study have an important contribution to the present knowledge on the
morphometric aspects and the growth parameters of the wedge clam in the Black
Sea.
