<span>Concentrations of Cd, Pb, Cu, and Zn were determined in surficial sediments from II sampling sites in Anzali wetland. Four different methods were tested to choose the most efficient procedure for determi-nation of the metals including: 1) HNO3-HCL digestion 2) HCL digestion 3) HNO3 digestion 4) Extraction with EDTA. The measurement of the metal levels was performed using atomic absorption spectroscopy. In order to interpret analytical results, several statistical methods were applied. There was statistically significant differences between the accumulation of the metals in sediments. While considerable differences could not be observed between the seasons. Different patterns could be detected at the levels of each heavy metal in the sampling sites. The sampling site eight showed the lowest similarity compared to others......</span>

<span>Determination of Formaldehyde in 5 species of Persian Gulf finfish and shellfish as an indicator of determination. In order determine the Ashelf lifeS of five finfish and shellfish species lizard fish, white pomfret, Spanish Mackerel, friglescale sardinella, green tiger shrimp meat, the amount of formaldehyde (FA) , total volatile Nitrogen (T.V.N) during cold storage were studied . A) The result indicator formaldehyde (FA) in this species. B) During storage in 0 °C - 20 °C - 40 °C the amount of Formaldehyde increase rapidly. C) The level of Formaldehyde concentration obtained in this species have been compared and discussed. D) Flucation in Formaldehyde concentration in this species does not show Name pattern. E)The largest and shortest were found to be belong to silver pomfret and lizardfish, T.V.N test in this study used as a subsidiary test......</span>

<span>The oligochaeta density and distribution in the southern coasts of the Caspian was surveyed. Sampling was carried out in the depths of 10-20-50-100 meters from to Bandar-e-Turkaman. The results indicated that oligochaeta density enhanced with the increase in depth (in the surveyed areas). The main reasons for the enhancement are the smaller sediments particles and higher density of organiv matter in deeper sea beds. The studies were carried out in three different phases and time span. Hence lots of differences in Oligocheata densities were observed in each square meter. Also their frequency varied in different seasons. The maximum was observed in autumn and the minimum in summer. Temperature is indicate as an important parameter in this survey and the average temperature in each depth is calculated......</span>

<span>To investigate the distribution of Copepodes in the southern basin of the Caspian Sea, in 1991 and 1992, 16 station along the shore and 8 stations in depths below 100 meters were set up. In all station two suborders, Viz, Calonoida and Cyclopoida, at differcnt stayes of life cycles were observed. Results show the Copepodes density decreases as the distance from shore increases, the density is also higher in the eastern and western parts than the central part of the sea. Calonoida and Nauplius density in all station were higher than Cyclopoida. While the maximum density of Nauplius occurred in the surface, the highest density, of Cyclopoida and Calonoida was observed in deeper parts......</span>

<span>61 specimens of pearl oyster (Pinctada fucata) were collected from Bandar-e-Nakhyloo in Hormozgan province and were subjected to biometrical measurements. The measurements carried out included dorsaventral and anteria-posteria measurements along with hinge length, Thickness, Muscle weight, oyster weight without shell, total body mass excluding gill, and total body mass. The maximum correlation coefficient (r=0.69) was obserued between total oyster weight and its weight without shell. In contrast, the least correlation coefficient (r=0.04) was found between thickness and muscle weight. It was revealed that the correlation between total oyster weight and hinge length follows a curvilinear pattern (r=0.34). Additionally correlation between dorsaventral measurement and total oyster weight showed a similar pattern (r=0.52). An estimate of available oyster muscle for conserving is given in the paper. Also, frequency, body weight without shell, muscle weight, dorsaventral measurements, .....</span>
