Abstract

North Aceh Regency - Lhokseumawe is an area that has several industries around its coast. These industries will directly or indirectly produce waste such as heavy metals. Heavy metals are dangerous materials that are toxic and difficult to decompose. This research aims to analyze the heavy metal content in the gills of mackerel ( Rastrelliger sp.) and its morphometric variations in the waters of North Aceh - Lhokseumawe. This research was conducted in March - July 2024 where the method used was an exploratory survey by determining observation locations using the purposive sampling method. The results of the research showed that the heavy metal content in the gills of mackerel ( Rastrelliger sp.) had heavy metal values of Pb and Cd (< 0.07 ppm and < 0.03 ppm). The results of the research show that the value of heavy metals is still below the food quality standard threshold and has no impact on fish respiratory organs (gills) based on SNI 7387 of 2009. The highest morphometric variation of mackerel based on observation location was measured at station 1. Based on sex, the highest measured morphometric value was found at type of female mackerel fish. Furthermore, morphometric measurements based on spatial/measured space showed the highest morphometric values found in the waters of North Aceh
