[ 2 ] - Evaluation of selected substrates for collection of hatchery reared black-lip pearl oyster (Pinctada margaritifera) spat

An experiment was conducted to investigate the effect of collector materials and position on Pinctada margaritifera spat attachment. Settlement on polyethylene pipes (54.6%) was significantly higher (P < 0.05) than on plastic baskets (25%). Significantly higher (P < 0.05) spat catch was recorded from the collectors which were installed on lower height of settlement tank than upper. The number o...

[ 5 ] - The Study of Food dietary Anadonta cygnea in Anzali Wetland

One of the unique and important aquatic species of Anzali wetland, Anadonta cygnea, native Anzali wetland and its rivers, and the most important two-body system of this blue system, has declined sharply in recent years due to various reasons. Is this species is considered to be smuggling and has a special sensitivity to environmental changes (biological pollution assessment).Anzali Wetland is a...

[ 6 ] - Effect of using various amounts of patin (Pangasianodon hypophthalmus) fish oil on physical and chemical properties of moisturizing hand cream

Hand cream is used for rehydrating and improving skin properties. The skin is the first point of contact with the environment. Thus having healthy skin with proper barrier properties is quite important. The beneficial effects of fish oil on skin make it a favorable ingredient to be used in hand care products. In the present study, the efficacy and stability of various hand cream formulations us...

عادات غذایی ماهی گوازیم دم رشته ­ای (Nemipterus japonicus)، در دوره زمانی 97-1396، به ­صورت فصلی در دریای عمان مورد بررسی قرار گرفت. در این تحقیق محتویات معده 210 عدد ماهی گوازیم دم رشته ­ای (91 عدد ماده و 119 عدد نر) مورد بررسی قرار گرفت. در این مطالعه برخی از شاخص ­ها مانند شاخص شدت ...

[ 9 ] - بررسی اکولوژی تغذیه و تخمین سطح غذایی گربه ماهی بزرگ (Netuma thalassina) در آب های شمال دریای عمان

مطالعه رژیم غذایی گربه ماهی بزرگ (Netuma thalassina) با بررسی ۱۹۸ عدد ماهی صید شده در آب های دریای عمان، به ­صورت فصلی انجام گرفت. در این مطالعه شاخص فراوانی وقوع شکار، شاخص شدت تغذیه، شاخص خالی بودن معده، میانگین سطح غذایی و نرخ غذای مصرفی محاسبه گردید. در مجموع ۶ رده تاکسونومیک عمده در محتویات معده این گونه ش...

[ 10 ] - Research Article: Trophic dynamics analysis and ecosystem structure for some fish species of northern Oman Sea

In the present study, a trophic structure model for some fish species of the northern Oman Sea is developed through using mass balance modeling software, Ecopath with Ecosim (EwE). In this model, we simulated 16 functional groups spread across an area of 3998.20 km2 from 2017 to 2018. Mean trophic level in the area of the present study was 3.49. Values calculated for system omnivory and connect...

[ 11 ] - Research Article: Feed comparison and feeding ecology in five sympatric teleost species of the northern Oman Sea

Investigating the relations and mechanisms of coexistence among sympatric species is essential to comprehend their ecological roles in the food webs. In the present study, the diet and trophic interactions of 5 abundant teleost species coexisting in the northern Oman Sea were examined using stomach contents analyses. The cumulative prey curves showed that the sample size of each studied species...
