Opis:
The major goal of this study is to determine the bioaccumulation of heavy metals in the tissues and bones of Red Hybrid Tilapia (Oreochromis niloticus) and Mackerel (Rastrelliger kanagurta) taken from two distinct sites in Terengganu state, Malaysia, namely Kijal and Paka. Zinc (Zn), copper (Cu), nickel (Ni), and lead (Pb)were the metals examined. Soil analysis also was carried out for the same elements. The tissues and bones of the fishes were separated before further analysis was made. Drying process technique was used to determine the moisture content for all samples at 80°C for 24 hours. Water content ranged between 70 & 77%. Triplicate samples were evaluated by using Atomic Absorption Spectrophotometer (AAS) to find out heavy metals concentration. Oven and Teflon beakers were used to fully digest all solid samples at 120oC for 3 hours. Highest readings of Zn, Ni and Pb were found in the fish bone for the samples collected from both mentioned locations. However, different pattern was noticed for Cu where higher values were found in the tissues for the same samples. Values of Pb in the tissues were higher than the acceptable value in edible fish by Food and Agriculture Organization (FAO); 1 ppm and Malaysian Food Act (MFR) & World Health Organization (WHO); 2 ppm, whereas values of Cu, Zn were in the acceptable range set by the same organizations. No values recommended for Ni by MFR. In general heavy metals in the bones and tissues from both locations can be sorted in descending order as follows; Pb>Zn>Cu>Ni. Soil samples collected from both locations showed different pattern where high concentration was found for Zn followed by Pb then Cu and Ni. Moreover analysis for soil samples collected from Paka River showed higher content for all elements compared to Kijal. More investigation is needed to clarify whether this contamination is solely from industry or due to geology of the area.

Opis:
This research aims to know the level of freshness of mackerel (Rastrelliger kanagurta (Cuvier, 1816)) contained in Rancaekek market, Resik market, and Tanjungsari market. Methods of the research was survey methods and the level of freshness of the sample using organoleptic test. The samples were observed organoleptically including the appearance of the eyes, gill appearance, mucus appearance, meat condition, aroma, and texture. Based on observations on the freshness of mackerel from the parameters of eye appearance, gill appearance, mucus condition, meat condition, aroma, and texture, it can be concluded that the fish marketed by Rancaekek market scored 7.1, which means that it is in the fresh category, fish marketed in the Resik market got a score of 7.4, which means it is in the fresh category, and the fish marketed by the Tanjungsari market gets a score of 6.9, which means that it is within the fresh limit.
