Untersuchung der winterlichen Vertikalkonvektion im Meer mit verankerten Profilstrommessern

The aim of the project was to investigate the process of small-scale structures as well as the temporal variability of convection processes with regard to the establishment of a climatology of the convection processes in the central Greenland Sea. In particular, the relation to environmental influences like heat exchange with the atmosphere or ice and the resulting changes of stratification has been studiedSIGLEAvailable from TIB Hannover: F93B1111+a / FIZ - Fachinformationszzentrum Karlsruhe / TIB - Technische InformationsbibliothekBundesministerium fuer Forschung und Technologie (BMFT), Bonn (Germany)DEGerman

Dokumentation und Massenbilanz des Chlorbiphenyl-Eintrags der Oder in die Suedpommersche Bucht

Under the EC sponsored research project ODER (Oder Discharge-Environmental Response) an investigation has been carried out in the coastal waters of Oder Haff, Achterwasser, Greifswalder Bodden, Oder Rinne, Arkona Basin and Bornholm Basin in order to estimate the PCB input via river Oder. For this purpose, ten sediment core samples were analysed for PCB content and composition. Sedimentological parameters such as water content, dry bulk density, grain size distribution, organic and anorganic carbon have been measured in parallel. Nine water samples have been collected in this region to determine the content of suspended particulate material and subsequently analysed for CB content and congener-specific composition. Particle free solution was analysed for CB composition and content in three of these nine samples. (orig.)Im Rahmen des von der EU gefoerderten Forschungsprojekts ODER (Oder Discharge-Environmental Response) wurden erste Untersuchungen zum Eintrag polychlorierter Biphenyle (CB) von der Oder in die Arbeitsgebiete Oder Haff, Achterwasser, Greifswalder Bodden, Oder Rinne sowie Arkona- und Bornholm-Becken durchgefuehrt. Hierzu wurden an zehn Sedimentkernen sedimentologische Parameter sowie erstmals Vertikalprofile fuer die CB-Gehalte und -Verteilung bestimmt. An insgesamt neun Wasserproben wurden der Gehalt an suspendiertem Material und organischem Kohlenstoff sowie die partikulaeren CB-Gehalte und -Verteilungen ermittelt. Fuer drei weitere Wasserproben wurden die geloesten CB-Konzentrationen und -Verteilungen analysiert.

Performance of juvenile and ongrowing common dentex (Dentex dentex, L. 1758, Sparidae) in relation to nutrition under culture

Common dentex (Dentex dentex) were reared from egg stage to marketable size in a flow-through system at ambient conditions during a three years period (1992-1994). A series of rearing experiments were conducted in order to determine biological traits important for the evaluation of this potential aquaculture candidate. In juveniles (2.5-50 g), growth rates were found to be exceptionally high compared to other aquaculture species and food conversion very efficient (FC#approx#1, based on food dry matter). Results wre attained under ambient conditions (Temperature: #approx#25 C, Salinity: 40-42 ppt). Feeding consisted of moist diets (35% H_2O) with high energy (22-24 MJ/kg) and high protein (51-53%) content. Feeding exclusively commercial dry pellets (isocaloric to the moist diet), resulted in significantly reduced growth rates, reduced food conversion efficiencies, increased mortalities due to agonistic behaviour and an increased disease susceptibility. The poor performance of test specimens fed dry diets compared to those fed self - prepared most diets was not explained by the different moisture content of the test diets (8-10% vs 35-50%). Common dentex reach marketable size (300-500 g) within 14-18 months after hatching under favourable ambient conditions (South Aegean Sea), while feeding self - prepared moist diets. This is in the range of established aquaculture species in the Mediterranean Sea. The possibility to protect common dentex against losses due to an infectious disease by oral application of different immunostimulants (#beta#-1,3/1,6 glucans; MacroGard"T"M, VitaStim"T"M) was tested in this study. Disease outbreaks are not securely prevented, but treated test groups showed lower overall mortality, while subsequent mortalities were clearly related to treatment. The study analyzes 9 morphometric characters (total length, standard length, fork length, pre- and post anal length, head length, body height, mouth opening, eye diameter) and describes their allometric development in juvenile and adult dentex (n=69-463). The occurrence of abnormalities was monitored and described during all rearing periods. Seven types of skeletal deformations and one abnormal scale development were identified. One incident of gas bubble disease, caused by a gas supersaturation of 110% is described. A swimbladder stress syndrome (SBSS) was assumed to occur during the acclimation of wild broodstock-fish to conditions in captivity.

Chlorierte Schadstoffe in Schweinswalen (Phocoena phocoena): Verteilung, Akkumulation und Metabolismus in Abhaengigkeit von der Struktur

Harbour porpoises are the most common cetaceans in the German North and Baltic Sea. Their population size has declined during the last decades. Beside the accidental catch, the depletion of food sources and the disturbance by marine traffic, organic contaminants are discussed as a possible reason for their decreasing number. Organochlorines such as chlorobiphenyls, chlorinated pesticides, dibenzodioxins and dibenzofurans are ubiquitous, anthropogenic environmental contaminants. Due to their lipophilicity and persistence they accumulate in the fatty tissues of marine mammals. These contaminants are supposed to be partly responsible for reproductive and immunological abnormalities in marine mammal populations. In the framework of the project 'Investigations on small cetaceans as a basis for a monitoring-programme', which was financed by the Federal Ministry of Science and Technology, investigations on organochlorines in harbour porpoises from the North Sea, Baltic Sea and the west coast off Greenland were carried out.
