A Study on The Nutritional Value of Razor Clam Solen Dactyls (Mollusca: Bivalvia) in The Ghouban Tidal Channel (Persian Gulf) By Measuring of Their Total Lipids, Carbohydrate and Protein

Abstract

This research took place to study to measure the total lipids and total protein content in a dominant razor clam of Solen dactyls. In the Gabon
tidal channel situated in the north west of the Persian Gulf, 10 specimens of Jack knife clam S. dactylus were collected randomly in autumn
2016 and spring 2017 from 4 stations. The clam is one of the most important species of the solenoid that inhabit in high and mid intertidal
sandy-muddy beach.
After sampling live specimens were transferred immediately to the laboratory and stored at -80°C until use. The total amount of protein with
Kjeldahl method, carbohydrates with AOAC methods and total lipid by soxhlet methods respectively were measured three repeats. The results
showed the amount of protein of S. Dactyls in autumn season was 17.93±1 and in spring 13.58±0.06 and results of fat in autumn season was
6.43±2.77 and in spring were 4.87±0.04 as well as in carbohydrates in autumn 3.12±0.01 that showed and in spring its 0.98±0.235. The values
of protein, fat and carbohydrate levels showed that the value of fat and protein in autumn was slightly higher than spring. Due to the presence
of gametes which are included fats. The result showed that S. dactylus is a generic clam and the gametogenic cycle began in the autumn season
and spring season.
