Condition Index, Meat Yield and Biochemical Composition of Mediterranean Mussel (Mytilus Galloprovincialis Lamarck, 1819) from Canakkale Strait, Turkey

Abstract

The present study was performed in Çanakkale Strait from September 2012 to August 2013. Biochemical composition (protein, total lipid, moisture, and ash), condition index, and meat yield of Mediterranean mussel, Mytilus galloprovincialis in the net systems hung out the open sea cage units monthly. The mean condition index and meat yield of M. galloprovincialis were found 8.12±0.48 and 16.07±0.70%, respectively. A positive correlation was found between condition index and protein, carbohydrate, and meat yield whereas a negative correlation was seen between condition index and weight, length, lipid, moisture, and ash. In terms of seasons, condition index and protein values were high in autumn, lipid values in summer, and carbohydrate values in spring.

An Assessment of the Cultivation Potential and Suitability for Human Consumption of Mediterranean Mussels (Mytilus galloprovincialis Lamarck, 1819) from the Yalova Coast of the Marmara Sea

“…In this study, Koru and Deveboynu stations were found to have lower MY and CI compared to Çınarcık and Kapaklı stations. Environmental parameters, size, and reproductive period are directly related to CI, MY, and SCI (Acarli et al, 2015;Vural et al, 2015;Acarlı et al, 2018;Kızılkaya et al, 2019;Biandolino et al, 2020;Yıldız et al, 2021). In this study, differences were found between stations (p<0.05).…”

“…In this study, the lowest MY was observed at Koru station (21.54±4.01%), and the highest at Çınarcık station (24.51±2.96%). Yıldız et al (2021) found that the MY and CI of M. galloprovincialis (83.69 mm in length) in the Çanakkale Strait was 17.79% and 9.33 in April, respectively. Lök et al (2011) was determined that MY and CI of M. galloprovincialis was 27.05% and 11.53 (51.22 mm in length) in the Sinop-Içliman (Black Sea), and 22.63% and 10.47 (62.56 mm in length) in Edincikaltı (Marmara), 18.26% and 9.93 (50.44 mm in length) in Mersin Bay (Aegean Sea), respectively.…”

Annual gametogenic phenology of oyster, Magallana bilineata (Röding, 1798) collected from the west coast of Moheshkhali Island, Cox's Bazar, Bangladesh

“…It is also applied as a measure of the apparent health and commercial quality of bivalves [ 21 , 43 ]. The monitoring of CI to assess growth in oysters has been widely documented [ 44 , 45 ]. As a physiological index, CI is highly influenced by gonadal development and the age of the oyster.…”

Morphometrics, Growth and Condition of the Invasive Bivalve Rangia cuneata during Colonisation of the Oder Estuary (North-Western Poland)

“…The condition index (CI) is commonly used to assess the health and quality of bivalves [24][25][26], and was calculated according to the following equation: CI = Tissue dry weight/Shell dry weight × 100…”
