The Natural Calcium and Phosporus Content in Two Fishbone of Commercial Species from Enggano Waters

Abstract Calcium and phosphorus are important elements needed for the growth and development of the body both in humans and other living things. The bones of Tiger Grouper Fish ( Epinephelus fuscoguttatus ) and Lencam Fish ( Lethrinus lentjan ) have a fairly high content of calcium and phosphorus. The purpose of this study was to determine the calcium and phosphorus content in the bones of Tiger Grouper Fish and Lencam Fish. This research was carried out in September-November 2023 with direct sampling of collectors in Banjarsari Village, Enggano Island. The calcium content test was performed using an Atomic Absorption Spectrophotometer (AAS) and the phosphorus content test was performed using a UV-Vis spectrophotometer. The results of this study showed that the calcium content in the bones of Tiger Grouper was 8.84% and for Lencam Fish was 7.97%, and the phosphorus content produced in both samples was 1.4% for Tiger Grouper Fish of 1.4% and 1.43% for Lencam Fish. Based on the results of the study, the calcium content in Tiger Grouper is greater than that of Lencam, while the phosphorus content in Tiger Grouper is smaller than Lencam Fish.
