    Description: Popkultur und Wissenschaft haben eines gemeinsam: Sie sind auf Dauer gestellte Zitationsmaschinen, die durch ständiges Referieren und Recyclen funktionieren. Dabei dient die Wiederverwertung und Entwicklung oftmals verschütteter Ideen anderer im Eigenen den Aktanten der Popkultur, um Aufmerksamkeit zu erregen; in der Wissenschaft hingegen wählt man sich als Aktant in die Netzwerke bisheriger Ansätze ein, um Erkenntnisse zu gewinnen. Der Band beschäftigt sich in einem ersten Teil mit grundlegenden transdisziplinären Überlegungen zu den reflexiven Zusammenhängen von Kultur(en) und Theorie(n). Die Fallstudien des zweiten Teils gehen auf konkrete Phänomene von Kulturbeobachtung wie Medienereignisse, Werbung, Mode, Musik und Theater ein. Mit Beiträgen von Jochen Bonz, Mercedes Bunz, Andreas Hepp, Silke Hohmann, Theo Hug, Christoph Jacke, Sebastian Jünger, Katrin Keller, Eva Kimminich, Joachim Knape, Birgit Richard, Siegfried J. Schmidt, Richard Shusterman, Mark Terkessidis, Angela Tillmann, Jörg van der Horst, Ralf Vollbrecht, Martin Zierold und Guido Zurstiege.

    Description: Caspian trout (Salmo trutta caspius) is one of valuable fishes of the Caspian sea for people living in the Northern coastal area of Iran. Since fish stock and natural resources protection is one the Iranian fisheries research objectives, the most activity on Caspian trout rehabilitation was focused on releasing thousands of smolts in the rivers discharge to Caspian Sea. Catch statistics of this species has declined over last decades thus this study on quality of provided brood stocks and producing fries with suitable quality can help rehabilitation and rearing of this valuable species. Several rivers were considered for providing brooders to keep genetic resources variety of sea stocks. In spawning season 25 (9 male, 16 female) and 30 (5 male, 25 female) brooders were collected from fishermen in Mazandaran rivers and Gyilan coasts provinces respectively. After propagation and larvae rearing, 11500 (10-15 g.) and 50000 (less than 10 g.) juveniles were released in Gyilan and Mazandaran rivers respectively.

    Description: Following to introduce Vannamei shrimp (Litopenaeus vannamei) into Iran aquaculture industries by fisheries organization its postlarvae were successfully reared in ponds in Bushehr and Choebdeh in Khuzestan. Due to activity of Shrimp site and importance of input and output water quality, this study was done in 11 stations including: two stations in Bahmanshir river, two station in C4 and C5 irrigation canals, six staions in active farms along C4 cannel (Yonesi, Mosavei and Salman Zadeh), and C5 cannel (Mohamadi, Khairi and Ashraf Por) and one staion in output draing were selected. Sampling were carried out from May2009 befor beginning stocking to harvest time in October 2009. Physico- chemical parameters and plankton sampled biweekly and benthic animals and heavy metals were sampled monthly. Some parameters such as pH and temperature by using portable multy parameters and others. Analyzed with standard methods. Heavy metals were measured by plarography method (797 Vamtro). Plankton and benthos samples were studied only in Bahmanshir station. According to results the maximum values for DO (11.1 ppm) PO4 (1.86 ppm) NO3 (8.4 ppm) and TSS (4992 ppm), pH (8.4) NO2 (0.18 ppm) BOD5 (9.06 ppm) were measured. In comparison to aquaculture water quality standards except for TSS in river stations others are located in allowable range. We didn’t observed any main changes in water quality from river to output drainage. The results of biotic parameters in river stations showed that diatoms were the most group of phytoplanktons. Zooplankton groups were Copepods, Rotifera and Protozoa. Tintinids and Nematoda larvae were the most abundant zooplankton. Benthic animals were included nine crustacean species and two annelid species. Isopods with 52% were the most and ant group.

    Description: An artificial Reef is a fabricated, underwater structure, typically built for promoting marine life in areas of generally featureless bottom. Creating artificial reefs began from 2000 in southern provinces in Iran. This study has surveyed about the Bushehr and Khozestan states. The objective is to determine the effectiveness of artificial reefs in attracting and enhancing the production different aquatics through increasing of fish assemblage and fishery. The performance of artificial reefs deployed off the coast of the Persian Gulf in 10 to 15m, was evaluated. The reefs comprised of seven artificial and one control (natural) statistical tests plan in three replicates. Three types of artificial reefs were used in this study. That two were designed reefs and one was not designed or used material. The experimental plan consisted (i) Reef ball (R), designed hemispherical shaped; (ii) Laneh Mahi (L), designed pyramid shaped; (iii) Used material (U); (iv) mixed (RL); (v) mixed (RU); (vi) mixed (LU); (vii) mixed (RLU); and (viii) control site (CS). Trap nets and under-water visual census surveys were adopted for seasonal sampling of fish aggregation. Results of statistical analysis using ANOVA and T-test of the mean Catch per Unit Effort (CPUE) showed significant difference (p〈0.05) in term of computing number of fish for aggregation of fishes. The study has concluded that reef deployments have influenced favorably the fish communities and fish harvests. Therefore, the artificial reefs, especially the mixed RLU, are appropriate tools for future fishing enhancement in the Persian Gulf of Iran.
