Chemical Analysis of Several Export Fish Species
- This research is concerned with chemical analysis of several export fish species. Some physicochemical properties, spoilage indicators and trace elements in several export fish (Bombay duck, Gold spotted grenadier anchovy. Butter catfish, Tilapia, Cirrhinus mrigal and Labeo rohita) were determined according to season. Fish is one of the main parts of our diet, as it includes nutritional elements such as protein, fat, ash, water, amino acids , several vitamins and minerals in sufficient amounts for healthy living. Freshwater fish (Butter catfish, Tilapia, Cirrhinus mriga and Labeo rohita) were collected from the Ayeyarwady Region, and marine water fish (Bombay duck and Gold spotted grenadier anchovy) were collected from Rakhine State. In the Bombay duck, Gold spotted grenadier anchovy. Butter catfish and Tilapia species, crude protein and fat content were found to be higher in the hot season than those in the other two seasons. The water content of these fish was higher in the rainy season than in the other two seasons. Spoilage indicators (TVB-N, TMA-N and NH3) were found to be higher in the hot season than in the rainy and cold seasons. Histamine, one of the biogenic amines for chemical hazards, was measured using the spectrophotometric method and found to be in the range of 0.05ppm to 31.44ppm in the hot season, 0.012ppm to 30.98 ppm in the rainy season and 0.007ppm to 15.35ppm in the cold season. Concentrations of histamine in seawater fish (Bombay duck and Gold spotted grenadier anchovy) were observed to be higher than those in freshwater fish (Tilapia and Butter catfish) in all seasons. Concentrations of trace elements in these fish were determined using Atomic Absorption Spectroscopy. The concentrations were as follows: Cu (0.15-2.34ppm), Pb (0.18-0.81ppm), Zn (1.04-9.13ppm), Cd (ND-0.57ppm), As (13.32-18.69ppm) and Fe (1.68-20.79ppm) in the hot season, Cu (0.13-1.08 ppm), Pb (0.8D-1.42 ppm), Zn (1.02-7.08ppm), Cd (ND-0.37ppm), As (10.15-18.71ppm) and Fe (1.35-19.19ppm) in the rainy season, and Cu (0.11-1.01ppm), Pb (0.25-1.01ppm), Zn (0.81-5.82ppm), Cd (ND 0.41ppm), Fe (0.55-19.01ppm), As (7.9-17.13ppm) in the cold season.
