Non-commercial fish species of shrimp trawls were studied monthly from October 2005 to September 2006 in Mahshahr creeks (Darvish, Doragh, Bihad, Ghazaleh, Ghanam, Zangi and Patil). The trawl nets had a cod-end mesh size of 24mm. Total catch was 6431 individuals weighing 55.5kg, and included 14 species of non-commercial fish species belonging to 14 families. The caught shrimp species were from ...
The term 'Workers' Councils' can perhaps stand as a catchall title for an unpremeditated, quasi-spontaneous, 'groundup' organisational form reproduced over many periods and across many countries by groups of workers previously unaware of such a structure or of its historical precedents. Its highest form the Soviet, its 'lowest' the simple workplace representatives' committee, this formation rec...
the gobies are non-commercial fishes in the iranian waters of the caspian sea for which population dynamics and stock status are poorly known. in this survey, we tried to define species diversity and catch per unit effort (cpue) of gobiidae by using beach seine nets in salmanshahr, the southern caspian sea. from march 2011 to april 2012, 224 specimens representing 4 gobiid species, belonging to...
This article analyses the development of competitive party politics in post-communist East Central Europe from a comparative perspective. The central concerns are party system stabilisation and change in Hungary, Poland, the Czech Republic and Slovakia, and implications for comparative theory. Starting from Lipset and Rokkan’s ‘cleavage model’, the article assesses the relevance of their key va...
The objective of the present study was to determine the effects of fish aggregation device (FAD) deployment on biodiversity, catch composition and length frequency distribution in the Qeshm Island handline fishery. Two FADs were deployed in the Qeshm Island. Four biodiversity indices including Margalef, Shannon-Weaver, Simpson and Pielou and also catch composition and length frequency distribut...
Broomrapes are obligate root parasitic weeds and major constraint to many dicotyledoncrops especially in Mediterranean agricultural lands. Due to the fact that no single controlmeasure is able to control broomrapes in the field satisfactorily, integrated management isrecommended in general. The use of of trap crops or catch crops is an important strategy forcontrolling the weeds; and allelopath...
The present study analysed the relationship between catch amounts of the Clupeidae species and monthly average weather temperature, rainfall, wave high and water depth in the southwestern of Caspian Sea. The data from two maritime consecutive years gathered by means of industrial fishing vessel were used in the data analysis. The results showed that the correlation between monthly average water...
Hydrodynamically confined flow device technology is a young research area with high practical application potential in surface processing, assay development, and in various areas of single cell research. Several variants have been developed, and most recently, theoretical and conceptual studies, as well as fully developed automated systems, were presented. In this article we review concepts, fa...
