INTERACTIVE EFFECTS OF DIET PROTEIN AND WATER SALINITY ON GROWTH AND SURVIVAL OF WHITE LEG SHRIMP (LITOPENAEUS VANNAMEI BOONE 1931)

This study was conducted in the Shrimp Reseach Center of Bushehr in winter 2005. We treated reared White Leg Shrimp (Litopenaeus vannamei Boone 1931) with five diets containing 20%, 25% ,30%, 35% and 40% protein levels and three salinity levels 15-17ppt, 27-30ppt, and 40-45ppt. We focused on growth, survival, food conversion ratio, hemolymph osmolality, hemolymph protein and corpse protein content. We applied 15 treatments each with three replicates in 45 tanks with 300 liter capacity. Shrimps average weight was about 2 grams at the start and reared after 60 days of culture. Shrimp biomass growth in 15-17 salinity was higher than other salinities showing statistically significant difference with those grew in 40-45ppt salinity (P>0.05). No statistically significant difference was found between growth of the shrimp in 15-17ppt and in 27-30ppt water. Survival in 15-17ppt salinity was 97.03, lower than other salinities, while those in 24-30ppt and 40-45ppt salinities had the highest survival 99.33%. The highest growth was seen in diet number 5 with 40 percent protein content which showed a meaningful difference to that of other diets (P<0.05). No statistically significant differences were found between diets in terms of production costs and survival rates

Assessment of Heavy Metals Concentration of Fish (Liza abu) in Karoon River, Khouzestan Province

This study investigates the presence of heavy metals such as copper, iron, zinc, mercury, lead, cadmium and manganes in muscle, liver and gill of fish (L.abu) in the Karoon River, in Khuzestan province. Samples were collected in winter 2010. After the biometric data of 72 specimens were recorded the samples of muscle, liver and gill were analysed. Sample preparation and analysis was done according to MOPPAM method. The concentrations of heavy metals in the dry digested samples of tissues were measured using Atomic Absorption Spectrophotometer (AAS). The results of this study showed that the average concentrations of heavy metals were negligible and at maximum value in muscle and giil tissues, respectively. Iron concentration was showed to be higher than those of zinc, lead, manganese, cadmium, copper and mercury in different organs of fish (Liza abu). (

Quran and Hadith position in Mathnawi Maanavi

Rumi has been a scholar and mystic poet and has had an irrefragable relationship with Quran and Prophetic Hadiths. That is why Mathnawi is a book that interprets and describes Quran and some Islamic educations -the Hadiths -in the form of poem, allegory, logic and mysticism. The eternality mystery of Mathnawi is that it has adopted from Quran in many cases, and thanks to this benefit from Quran and Hadith, it has reached immortality. The aim of this research is to investigate the mystic views of Rumi about Quran and Hadith and reflecting them in MathnawiMaanavi. The research methodology is an analytical and descriptive method and this is a library research. The information gathering tool is not-taking. Having read the related books, magazines and theses, the researchertried to collect credible information
