A Bayesian network for investigating the decline in fish catch in Switzerland
Catches of brown trout have decreased about 50% in many rivers and streams in Switzerland in the past 15 years. Additionally, the health status of numerous brown trout populations has been assessed to be impaired. In order to evaluate the causes for these phenomena, a nationwide interdisciplinary project named “Fischnetz” was launched in 1999. Twelve hypotheses for the fish population declines ...
متن کاملFish harder; catch more?
Perhaps the most fundamental insight from fishery science is that ecosystems impose important and predictable constraints on food production from the sea. The familiar hump-shaped growth curve implies that the growth rate and carrying capacity of a species limit its production: Once stocks are depleted, further increasing fishing pressure will only lead to decreases in catch. This logic underpi...
متن کاملIntrinsic vulnerability in the global fish catch
We have identified the marine fish taxa that are most vulnerable to exploitation, by compiling an index of intrinsic vulnerability based on life history traits. Since 1950, the global fish catch has been increasingly dominated by species with low intrinsic vulnerability, indicated by a decline in mean vulnerability of the taxa in the catches. This decline is strongest in catches of coral reef f...
متن کاملFirst Catch Your Fish: Designing a “Low Energy Fish” Label
This paper explores the application of information design principles to label design for fish packaging, identifying energy implications for the product. This stage of the project has consisted of: A review and distillation of the relevant literature on information and label design; environmental and labelling standards; and literature on consumer reaction to the design and information content ...
متن کاملSurprising decline of cardiovascular mortality in Switzerland: 1951-1976.
In Switzerland the age-standardised death rate for 'all diseases of the circulatory system' decreased by 22% in males and by 43% in females between 1951 and 1976, which represented a third and nearly a half respectively of the decrease in all deaths. Mortality was reduced by 13% in males and by 40% in females for non-rheumatic heart disease and hypertension, and by 36% and 47% respectively for ...
