Description: This study was determined some important extracted materials, Such as : Alginates of sodium & calcium and alginic acid in three species of brown seaweeds (Sargassum illicifolium , Cystoseira indica and Nizimuddinia zanardinii) during in different season in 1387 in coastal erea of Sistan and Baluochestan Provience. At First seaweeds sample were colected from sea beach and transferd to lab, so washed in fresh water and dried in the sun.

Description: In this project, the nutritional effects of Sargassum illicifolium Chabahar bay-Oman Sea, on growth and survival rates of whiteleg shrimp (Litopenaeus vannamei) were studied. The seaweed collected from 6 coastal area, rinsed, dried, powdered and measured the nutritional values in laboratory for surveying statistically. According to the high nutritional value of Tis coastal seaweed, this variate seaweed powder, replaced with protein resources (fish meal and Soy and Wheat) of whiteleg shrimp feed which was formulated by Havorash feed factory of Boshehr in four treatments (A: as control without any replacement) B: with 5%, C: 10 % and D: 15% seaweed replacement, each with three replicates in order to obtain isonitrogenus 33% CP., and Isocaloric (13% fat and 15% carbohydrate) feed. The weighed milled ingredients were carefully mixed using a laboratory food mixer. The mixtures were primed with 30% hot water to yield a suitable pulp. Wet diets were made into 2 mm pellet size and dried at 40 °C in a drying cabinet and maintained in standard condition which was used according to daily need shrimp, calculated by each 10 days biometry. Water stability and absorbtion capacity of the pellets in sea water were measured and compared statistically. Juvenile shrimps (Initial body weight =3 g) brought from Jask hatchery, acclimazed for one week in Chabahar hatchery condition and feeding daily 3-5% body weight. Abiotical parameters and weight and length biometrics were measured two days and 10 days, respectively. After 45 days and final biometry, FCR, CF, SGR, caracas analysis, muscle colourimetery with HPLC were done, tasted with pp Plot for determining the parametric data and statistically differences using one – way ANOVA, Duncan test of SPSS software. The Tis coastal seaweed with 9.8% CP, 2% lipid and 23% carbohydrate had higher nutritional value compared to the other gathered seaweed. Also amino acid and fatty acid profiles, vitamins and minerals were measured in all seaweed samples each, with three replications. As result, the water stability of D feed treatment in seawater (98%) and C (97%) had statistical differences with A and B (95% stability) (P〈0.05). Water absorption capacity of feeds after one hour immersion in seawater showed significance difference between D (110%) and three others, C(100%), B(85% and control(80%) (P〈0.05). Shrimp growth data, after the end of experiment revealed that seaweed feed treatments had no any differences with control group significantly. However, the absolute growth rate datas of D treatment were higher than others and the lower weight and lenght were measured in control group shrimp. FCR had difference between seaweed treatments and control statistically. There are no any differences between caracas lipid treatments (P〉0.05) but Cholestrol content of, showed differences between all, significantly (P〈0.05) which was the highest (121.68±12.12) in D and the lowest in A (147.92±11.02). Feed treatment D and C performed colour changes pink partial orang and pink in shrimp muscle with no any difference compared to white and none colour in shrimp were fed B and A feed treatments . It seems this colour changing can be playing a major role in market acceptability.

Description: Breeding has moved beyond the point of simply propagating random stock. Genetic potential can be improved by establishing and crossing genetically defined strains, crossing species and manipulating gametes. Some of these activities require cryopreservation of semen. Cryopreserved sperm could also be a means of exchange of genetic material between locations and populations when transportation of live fish is restricted. In this study we had a survey on rainbow trout sperm quality in Genetic and Breeding Center for Coldwatwr Fishes, Shahid Motahari, Yasouj. Then Cryopreservation trials on rainbow trout (Oncorhynchus mykiss) sperm were carried out using six basic extenders. Egg batches of 25 g were inseminated with semen frozen in five 0.5-ml straws. Thowing temperature of cryopreserved sperm also was tested. In anather trial we investigate different cryoprotectant. The result showd that the best period for sperm collection in this center was from Novamber to January. The best extender based on sperm motility parameters were extender 2 and 1 with 57.2 and 56.9% fertilisatin rates, respectively. So this two extender were used in the further experiments. The best thowing temperathre was 25°C in 30s. Testing different cryoprotectant, adding 10% methanol to extender 1 gave the highest fertilization rate (64.6%) among cryoprotectant that used with this extender. In the other extender (2) adding 5% DMSO and mixture of 5% DMSO and 1% glycerol gave the highest fertilization rates (64.8% and 67.0%, respectively). In conclusion using extender 1 and 2 with mentioned cryoprotectant and thowing rate of 25°C in 30 s was recammended for rainbow trout sperm cryopreservation.

Description: A sharp decline in natural population of Caspian brown trout lead to implementing of restocking program in Iran. Along the stock recovery program, the artificial production of this species has been attracted too much attention in recent years. The objective of the study is to assess the effects of protein and energy levels of diet on fish performance, growth efficiency of Caspian brown trout in order to develop a proper diet for production of this species. Six experimental diets were formulated by replacing casein as a pure protein source with fat as an energy source in the diets according to a 3×2 factorial design. The diet was assigned to 18 tanks with 50 fish each, with three replicated for each diet. The experiment was conducted for 8-weeks with Caspian brown trout with an initial body weight of around 7 g. Caspian brown trout demonstrated a better FCR and a larger SGR at lower protein levels (45 and 50%) in comparison to high protein level (55%; P〈0.05). Protein efficiency ratio improved by a decrease in protein content of the diet (P〈0.05), but energy content of diets does not affect any growth related parameter such as FCR, SGR and PER. There was also no interaction between protein and energy levels in the growth related parameters, suggesting the effect of protein on the growth parameters in Caspian brown trout did not depend on energy levels of diet. In conclusion diet containing 50% protein can support the maximum growth. High dietary energy level of the diet dose in cooperate in protein sparing effect.
