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...

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...

High population pressure in coastal areas has led to loss in many mangrove areas. Although these areas are fish nursery grounds, but there are no accurate and up-to-date data available. In this research, the catch data in the Qeshm Island marine protected area (MPA) were investigated using 11 stake nets. Totally, 81 specimens belong to 60 genera and 63 families caught, which majority of them we...

Visual cues play important roles in sea turtle foraging behavior and likely influence their interactions with fishing gear. Altering these cues may be a useful strategy to reduce the incidental catch of sea turtles in various fisheries. We examined the potential effectiveness of 3 visual cues — shark shapes placed along the length of the gill net, illumination of nets by LED lights, and nets il...

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...
