A number of laboratory studies and some field monitoring have since then been carried out. High concentrations of triorganotins have been found in the sound between Denmark and Sweden. Also, a study of the concentrations of organotins in biota from Swedish coastal waters, showed the presence of di- and tributyltins in herring and blue mussels from all studied areas. Present research is mainly oriented towards field studies. The Governments of Denmark, Norway and Sweden are in the process of regulating the use of organotins in shipbottom paints. It is not clear yet what kind of restrictions that are planned. Furthermore it is possible that a recommendation on some kind of joint action will be made by the contracting parties of the Helsinki (Baltic Sea) Convention.

Data collection in the Curieuse Marine Park in the Seychelles was instrumental in guiding government policy over the management of marine protected areas, especially those that have resilient coral ecosystems. Without such important and vital information politicians, parliamentarians, local governments and MPA managers would not be able to take the decisions which take into consideration coral reef recovery and conservation issues. This particular report seeks to bring together research and monitoring on environmental and socio-economic aspects and their relevance to management and policy approaches to education and community-based activities.

The area also receives unknown amounts of other effluents rich in organic matter and nutrients. The abundance of bacteria was measured by epifluorescent direct counts, and productivity was estimated by 3H-thymidine uptake measurements. The results showed a clear stimulation of the primary productivity as well as elevated amounts of chlorophyll a in the area receiving the effluent. Both bacterial abundances and production were an order of magnitude higher in a

The catastrophic tsunami in December 2004 affected local communities, and ways in which they utilized marine resources, while impacts on reef resources were patchy. Limited data and information on coral reef condition prior to the tsunami has highlighted the need for regular long-term coral reef monitoring to assess reef recovery from the tsunami and from ...

This publication reflects the evolution of the CORDIO programme in response to progressing threats from climate change as well as human activities. In all, the report includes 48 articles in sections covering overviews and regional summaries; reports on status, tsunami impact, biological research, fish spawning aggregations, artisanal fisheries, socioeconomics and livelihoods, and education and awareness.

Global mean temperature has risen by about 0.6 degrees C during the 20th century, greater than during any other century in the last 1000 years. Subsequently, climate change is likely to have detrimental effects on all global natural and anthropogenic systems. Climate change will have consequences for the structure and function of ecosystems and all the major global biomes. Also agricultural production and productivity will alter, and physical effects will take place on the environment affecting those that inhabit it. For example, sea level rise and climatic variations will have implications for human health, land use and coastal infrastructure. This report aims to identify the current and proposed research and assessments being undertaken by international organizations as well as the major national research groups regarding climate change and its effects on ecosystems, on agriculture (including fisheries...

Le pays a une superficie terrestre totale de 65 000 km2, si l’on y inclut les eaux continentales, et de 62 705 km2, les eaux interieures exclues. Bien que le littoral s’etende sur 1739,3 km environ, le plateau continental couvre 30 000 km2, ce qui represente une bande etroite de superficie relativement faible par rapport au plateau continental d’autres pays insulaires. Les cotes de l’ile abritent des ecosystemes tres riches, tels que des mangroves, des recifs coralliens, des herbiers marins et des marais. Ces ecosystemes cotiers offrent de precieux bienfaits aux habitants de ce pays, les populations du littoral en particulier. Ils constituent une source d’aliments et de revenus depuis des siecles, et leur exploitation s’intensifie a un rythme alarmant. Le prelevement et l’exportation d’organismes vivant dans ces ecosystemes cotiers...
