The Karoun River is major source of water for warm‌water fish culture industry in southwest of Iran. The aim of the present study was to investigate the distribution of mercury in tissues of marketable common carp and in bottom sediments of fish farms in Khouzestan province. This study was carried out on 45 fish farms that are located on the bank of the Karoun River in Khouzestan province, sout...

Carp is one of the most widely cultivated warm water fish, which has been introduced into many countries. It is essential for the manager of a carp farm to know the production costs and their evolution, showing the main inputs on which the cost reduction is worth effort. In Iran, carp farming is mainly based on common carp, silver carp, grass carp, and bighead carp, which were often reared in p...

Quantitative analysis of production through evaluation of inputs consumption quantity is of main principles in agricultural policies, which is followed by increasing in production through optimal use of resources. This study has been conducted to estimate different types of production functions in mechanized farms of broiler chicks located in Gorgan city. Cross-section survey data were gathered...

Abstract: Commonly, for being done a numerical modeling of any natural phenomenon, like as water flow pattern, need to an exquisite and modify calculated mesh. For gaining this standard calculated mesh, different calculated meshes must be analyzed sensitively. Thus, the optimum calculated mesh could be selected. At the present paper, the first, a powerful two dimensional numerical model which i...

The role of escaped farmed salmon in spreading infectious agents from aquaculture to wild salmonid populations is largely unknown. This is a case study of potential disease interaction between escaped farmed and wild fish populations. In summer 2012, significant numbers of farmed Atlantic salmon were captured in the Hardangerfjord and in a local river. Genetic analyses of 59 of the escaped salm...

The reference to ethnicity in the 2012 National Suicide Prevention Strategy for England (1) is mainly with regard to promoting mental health in Black and Minority Ethnic (BME) groups. However, there is little detailed information about any specific strategy to reduce suicide rates in BME groups. The Suicide Prevention Strategy and Action Plan for Northern Ireland has only one brief reference re...
