BIVALVES IN NORTH ACEH WATERS: A NUTRITIONAL EVALUATION BASED ON SPECIES AND ENVIRONMENTAL CHARACTERISTICS

Abstract

Bivalvia, commonly known as shellfish, represents a diverse group of marine organisms found abundantly in Indonesian waters. The marine bivalves, including those inhabiting brackish waters and estuaries, are estimated to comprise around 8,000 species belonging to 4 subclasses and 99 families with 1,100 genera. These shellfish species exhibit versatility, being capable of thriving in various water types, encompassing freshwater, estuarine, and marine environments. Owing to their palatable taste, ease of cultivation, and high nutritional value, shellfish have garnered significant attention and serve as a crucial biological resource with substantial economic importance. Rich in nutrients such as protein, fat, carbohydrates, vitamins, and minerals, shellfish have become a favored dietary option for many, while their byproducts, such as shells, find application in the production of lime, decorations, and as a calcium source. The nutritional content of shellfish is influenced by various factors, including habitat, species, sex, age, diet, temperature, and season, leading to significant variations in composition among different locations and environmental conditions. Consequently, it becomes essential to analyze the nutritional content of shellfish to ascertain their quality in specific regions. Although various species of shellfish have been consumed by communities in the Aceh waters, scientific reports on the proximate composition of bivalves in North Aceh have been lacking. This study, therefore, aims to address this knowledge gap by investigating the relative arrangement of bivalves in North Aceh waters based on species variations and differences in environmental characteristics. The findings from this study will contribute valuable insights into the nutritional profile of bivalves in the region, aiding in their sustainable management and potential utilization as alternative sources of omega-3, omega-6, omega-9, vitamins A and D, and essential minerals.
