This study was conducted to determine regional variation in growth characteristics and age structure of Squalius cephalus (Linnaeus, 1758) in the Southern Caspian Sea basin from April to June 2011. A total of 958 specimens from 3 areas including: Golestan (area 1), Mazandaran (area 2) and Guilan(area 3) were collected. In southern Caspian basin, the total length and weight of specimens ranged 22.00-30.00 cm and 138.62-347.70 g, respectively.The ages ranged from 0+ to 5+ years for males and from 0+ to 6+ years for females in all sampling areas. Parameters of von Bertalanffy growth function were different between males and females of each area and between the same sexes of different areas. The largest L∞ was found in the area 3 for female (L∞=38.97 cm).According to b values obtained, both sexes (except males of station 1) show a positive allometric growth. The highest values of condition factor were observed for males in early June. The result indicates that higher value of growth rate was for females.

Abstract Recently use of some nutritive additive such as plant extracts increased in aquaculture. Hydroalcoholic extract of Plantago ovata (POE) supplemented to fish food at four different levels (0, 0.1, 0.5 and 1 percent) and some growth parameters, Hepatosomatic index and Spleen of Oncorhynchus mykiss were investigated. This herb has antibacterial properties. 360 juvenile Oncorhynchus mykiss (30±5.23) randomly divided in twelve groups (four treatments and three replicates). All groups fed with experimental diet for 60 days. Bioassay conducted one and sixty days after applying treatment, and growth parameters were investigated. Finally Liver and Spleen of fishes weighed and results compared between treatments. Results showed that almost all growth parameters were increased in groups fed with 0.5 and 1 percent supplemented food with POE compare to the control group (P0.05). It can be concluded that POE can stimulate growth of rainbow trout and it has not negative effective on the Liver of juveniles even it has some good effects on the efficiency of spleen.

Abstract The purpose of this project was to study the effect of intraocular pressure (IOP) stress on the cross section of the optic nerve. Specifications for the dimensional model based on a digital image of a person's eyes to the inner radius of the eye: 12 mm, sclera thickness mm 0.8 and cross section optic nerve: a circle of radius of 1.75 mm was done by the intraocular pressure to 15 mm Hg or 2 Kpa was considered.Using this model considers stress as a side effect placed on the optic nerve in an arbitrary and disparate examination. Within the two different kinds of models, both the sclera and the nerve are considered the properties of each from theanalysis softwareis incorporated. Utilizing software with element solid 95 for the analysis can create a whole model grid analysis, and the model is intended to be an isotropic model.The model results showed the effects of intraocular pressure and stress levels in the central area of the sclera. The surrounding area around the nerve is greater and the surrounding area of the nerve level is lower than the range. The damages created the eyes as a result of the upward pressure first started from the surrounding area of the eye and eventually, the function of the nerve is destroyed and because these areas are very sensitive, to have knowledge of the change in tension is very important for us. Even slight pressure can cause applied tension to the optic nerve, leading to nerve damage that becomes irreparable.

Despite the application of Marsh frog Rana (Pelophylax) ridibunda in research, there is little information about the biology of different populations of this frog, especially in southern Iran Provinces. The first aim of this study was to investigate differences in biometric characteristics especially between male and female from different populations of species in Fars province. The second aim was the histological study on the male and female gonads which can help to explore some reproductive strategies of the frog in this region (Fars Province). This study will determine whether at the time of spawning, the gonads(testies and ovaries) are completely depleted from egg and sperm. In addition to this, the possibility of guessing the ability of the marsh frogs to spawn more than once during the reproductive season will be investigated. For this purpose 120 samples (87 females and 33 annuly males) from different population areas (Ghadamgah, Mehkoyeh, Kohmareh Sorkhi and Pol Berenjie) were collected. Samples were fixed in formaldehyde and transferred to the laboratory. Morphometric measurements were made and samples labeled. For histological study of gonads, adult pairs in amplexuses situation were collected from the natural breeding sites. One-way analysis of variance (ANOVA) showed that the samples from four population sites were significantly different (P

Abstract The Saffron plant (Crocus sativus), a native plant from Iran and especially of Khorasan region, has a specific place for people's diet. According to several studies about effects of Saffron and because there are no specific studies on the effects of Saffron on the development of Drosophila melanogaster as an animal model, this subject is being evaluated in the current study. A total of 5 pairs of 3-days-old wild Drosophila melanogaster were transferred to every culture plate containing different concentrations of Saffron in order to intercross and oviposition and were brought out after 8 hrs. sampling of larvae were performed in the seven steps at intervals of twelve hours and in each step, Morphometrical changes in the length and width of the larvae, were studied. The obtained data were evaluated statistically using SAS software, The variance between groups were evaluated by the test of One way ANOVA, and the mean of data were compared using Ttukey test with minimum significance level of p in high concentrations, has inverse effect on the biology of this insect.

Zoning and implementation of strict program for each zone must be done to procurement of management goals in protected areas. In order to evaluate the ecological potential of Kuh-e Gorm, non-hunting area (83410 ha) in Fars province, possibility of its conversion to a protected area and land management, zoning has been performed using GIS software. Thus, to pursue this purposes, nocturnal and daily surveys were done to identify vegetation communities and animal species. Ecological and socio-economic resources were initially surveyed and mapped (1:100.000). Overlaying of different maps, created final map of environmental units (with 625 environmental units). Table of environmental units was completed and positional data were analyzed, then area was zoned for mentioned purposes. The result show that 7 zones are possible in the area as follows: 10.74% of the area is suitable for restricted nature reserve, safe area zone 31.86% for protected area zone, 2.40% for restricted use zone, 46.88% for extensive use zone, 4.11% for rehabilitation zone, 0.61% for special use zone and 3.40% for buffer zone. In total 42% of allocated zones are suitable for conservational proposes. Some animal species such as Capra aegagrus, Lutra lutra, Dryomys nitedula, Aquila chrysaetos, Falco tinnunculus, varanus griseus and Testudo graeca are important in term of conservational value.
