Effects of Drying on the Biochemical Composition of <i>atherina boyeri</i>from the Tunisian Coast

The effects of solar and experimental drying on the protein concentration and total fatty acid (TFA) content of the muscles of atherina boyeri (sand smelt) were studied. The percentage of protein was 18.3% for fresh fish and 14.2% for sun-dried fish, while TFA content was 4.9 g/100g and 0.5 g/100g. After the drying experiment, the percentage of protein was 23% and the fatty acid (FA) content was 2.8 g/100g. The results show that natural or experimental drying favors saturated fatty acids. The n-3 polyunsaturated fatty acids (PUFAs) are less sensitive to heat than the n-6 PUFAs. From a nutritional point of view, it seems that the drying conditions, where parameters are T = 50℃, moisture = 30% and air speed = 2 m/s, would be the most beneficial for the preservation of sand smelt.

Reproduction of <i>atherina lagunae</i>from the Tunis North Lake

引用

Journal of Water Resource and Protection 2012年第9期4卷 779-782页

In this study, the reproduction of the sand smelt, atherina lagunae, from the Tunis North Lake is investigated. The smallest mature female was 39 mm total length (TL). Fifty percent of the females were mature at 58 mm (TL). The yearly and monthly average gonadosomatic indexes (GSI) are presented. The average value of GSI for the 12-month period was respectively 3.02%, 2.57% and 2.8% for females, males and both sexes. The GSI began to increase in March (2.37% for females and 2.12% for males). The maximum GSI was recorded in May, 11.29% for females and 10.03% for males. The highest values were recorded between March and July, indicating the reproduction period of atherina lagunae in the Tunis North Lake. Similar GSI values were recorded in sand smelt males from brackish lagoons of southern France.

Determination of P, Ca, Zn, Cd and Pb concentrations in muscle, gills, liver, gonads and skeletons of two natural populations of atherina lagunae in North Tunis Lake, Tunisia

引用

Journal of Water Resource and Protection 2011年第6期3卷 421-428页

作者： N. Ayed E. Faure J-P. Quignard M. Trabelsi 不详

In this study, zinc (Zn), cadmium (Cd), lead (Pb), phosphorus (P) and calcium (Ca) concentrations in mus-cles, gills, liver, gonads and skeletons of two natural populations of sand smelt atherina lagunae (Teleostean, Atherinidae) normal and deformed, as well as bioaccumulation of these elements from the water and the sediment in the North Tunis Lake were investigated. The analysis of Ca was performed with flame atomic absorption spectrometry. The average concentrations of Ca in the different tissues analyzed show higher val-ues in healthy atherines except in gonads where the average concentration of Ca in deformed atherines sig-nificantly exceeds that in normal atherines (p atherina lagunae in North Tunis Lake were very high compared to other studies in other lagoons. The highest concentrations were found in deformed atherines. The differences are significant for all tissues studied (p atherina lagunae. The potential rate of Cd was below the detection limit in the different organs analyzed, in water and sediment.
