Solen dactylus inhabits on sandy–muddy beaches which is distributed throughout the coast of the northern Persian Gulf. The aim of this study is investigate effect of different habitats on proximate composition of S. dactylus. For this purpose, 20 oyster were collected from Bandar Abbas and Sirik city. 16 different types of amino acids were identified. The highest levels of essential and non-essential amino acids were lysine and glutamine in Sirik, arginine and glutamine in Bandar Abbas. Also, 30 different types of fatty acids were identified. The most and least saturated fatty acids abundant identified were palmitic acid and henicosilicic acid in Sirik samples, palmitic acid and pentadecylic acid in Bandar Abbas samples. Regarding monounsaturated fatty acids, the most and least fatty acids abundant were cis-oleic acid and gadolinic acid in samples collected from Sirik, cis-oleic acid and cis-10-pentadecylic acid in Bandar Abbas samples. Docosahexaenoic and eicosapentaenoic acid were identified as the highest and lowest polyunsaturated fatty acids in the samples collected in Sirik, docosahexaenoic acid and tert-linoleic acid were identified as the highest and lowest polyunsaturated fatty acids in the samples collected in Bandar Abbas. The results showed that the moisture, protein and ash content in samples collected from soil (medium sand classified) in the Sirik region were significantly higher than those in the samples collected from soil (fine sand classified) in Bandar Abbas (P<0.5). Based on the results obtained, S. dactylus is a good source of amino acids and fatty acids.

Fairy Shrimps (Anostraca) have a great importance as live food in aquatic animals larviculture. They are important for enhancing growth rate and survival rate in various aquatic animals specially, sturgeon, salmonidae, Astacus leptodactylus. Fatty acid profile of fairy shrimps Chirocephalus skorikowi and Streptocephalus torvicornis from Aigher Goli and Ghom Tappeh pools of East Azerbaijan, Iran were determined using GC technique. The results showed that they had a large amount of EPA, DHA, Σ n-3 HUFA Linolenic acid and Linoleic acid, as though their highest amounts in various pools were; 9.85, 1.05, 10.30, 12.73 and 5.75 percent respectively, that had a great value comparing with Artemia. These animals contain of 11-50 %protein, highly unsaturated fatty acid specialties such as high amounts of EPA and DHA, carotenid complexes and as a live food enable to provide nutritious needs of growth stages of various aquatic animals (specially in sensitive larval stages) and improve their life spans and meat quality.
