Fish 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 کاملCoral decline threatens fish biodiversity in marine reserves.
The worldwide decline in coral cover has serious implications for the health of coral reefs. But what is the future of reef fish assemblages? Marine reserves can protect fish from exploitation, but do they protect fish biodiversity in degrading environments? The answer appears to be no, as indicated by our 8-year study in Papua New Guinea. A devastating decline in coral cover caused a parallel ...
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 کاملFish Oils in Human Health
Fish oils, rich in n-3 PUFA, give rise to an altered balance of eicosanoids involved in haemostatic regulation. Accordingly they lead to reduced platelet sensetivity to aggregating agents in vitro. Observational studies in man using cross-sectional studies, clinical studies and secondary prevention trials have shown that moderate intakes of fish oil reduces risk of death from coronary heart dis...
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 ...
