Abstract
.The results of ANOVA showed that the highest rate of lipid per liter in salinity of 45 g / l and the amount was 98.74%, but there was not significant difference with other treatments. Among all the fatty acids measured, Myristic acid has the highest values in all 4 treatments, however, showed the highest ...

.The results of ANOVA showed that the highest rate of lipid per liter in salinity of 45 g / l and the amount was 98.74%, but there was not significant difference with other treatments. Among all the fatty acids measured, Myristic acid has the highest values in all 4 treatments, however, showed the highest value in treatment 4 (salinity of 45 g / L), total saturated fatty acids and also total monounsaturated fatty acids(MUFA) showed not significant difference between treatments(p>0.05). total polyunsaturated fatty acids(PUFA) and also total omega-6 fatty acids had the highest valus in treatment 4 (salinity of 45 g / L), but total omega-3 fatty acids had highest valus in treatment 3(salinity of 30g/l). Also in the case of Protein, The highest valus of protein was observed in treatment 2 With the amount of 60.21% and following that, the treatment 1 with the amount of 51.71% and treatment 3 with amount of 49.29% were placed respectively in degrees the second and third. The lowest valus of protein was observed in treatment 4 with amount of 47.71%. The findings of this research showed that Spirulina microalgae could be grow successfully in high salinity waters without major impact on their fatty acids.

Goat fishes are marine fish that live in shallow water and they have distributed through the Persian Gulf and Oman Sea. They have useful unsaturated fatty acids. There are many document about classification and ecological study but we didn`t find any paper on fatty acid profile. In this research goat fishes catched from Mahshahr fishery port in two seasons autumn and spring by local fisherman by gillnet. Thirty fishes were chosen accidently and kept them in ice and transferring to the laboratory. The amount of their fatty acids was measured with GC_FDI instrument and two important indices (IT and IA) were calculated. The results were compared by one way Variance analysis and a test called (Tocky and Doncken). Differences between two season (spring and autumn)'s fatty acids were significant. And the amount of unsaturated fatty acids in autumn was more than spring.
