TLDR
In this article, a more holistic approach incorporating interspecific interactions and physical environmental influences would contribute to greater sustainability by reducing the uncertainty in predictions and transforming the management process to reduce the influence of pressure for greater harvest holds more immediate promise.Abstract:
The global marine fish catch is approaching its upper limit. The number of overfished populations, as well as the indirect effects of fisheries on marine ecosystems, indicate that management has failed to achieve a principal goal, sustainability. This failure is primarily due to continually increasing harvest rates in response to incessant sociopolitical pressure for greater harvests and the intrinsic uncertainty in predicting the harvest that will cause population collapse. A more holistic approach incorporating interspecific interactions and physical environmental influences would contribute to greater sustainability by reducing the uncertainty in predictions. However, transforming the management process to reduce the influence of pressure for greater harvest holds more immediate promise.read more

Research needs for the management of water quality issues, particularly phosphorus and oxygen concentrations, related to salmonid cage aquaculture in Canadian freshwaters
TL;DR: In this article, the authors review the state of science of the water quality implications of cage aquaculture and identify 11 knowledge gaps that currently hamper the development of sound, science-based cage culture management instruments.

Assessing the impact of removing reserve status on the Abore Reef fish assemblage in New Caledonia
TL;DR: In this article, a statistical approach based on multivariate analysis and general linear models was proposed to test the consequences of removal of reserve status from the Abore Reef fish assemblage of the New Caledonia reef reserve, New Guinea.

Paradox of marine protected areas: suppression of fishing may cause species loss
TL;DR: It is demonstrated that establishment of an MPA can sometimes result in a considerable decline, or even extinction, of a species, and a mobile predator that migrates adaptively rather than randomly is associated with a greater reduction in prey abundance.

Scaling restoration of American lobsters: combined demographic and discounting model for an exploited species
TL;DR: The economic concept of discounting is applied to allow quantification of the scale of restor- tion needed to compensate for both the magnitude of the estimated loss of American lobsters and the time lags between loss and restoration following a major oil spill.

Cadmium--copper antagonism in seaweeds inhabiting coastal areas affected by copper mine waste disposals.
TL;DR: Overall, the work confirms that macroalgae are useful indicators of metal contamination and may be used as in situ biomonitors for labile forms of metals, like free Cu2+.

Biodiversity and stability in grasslands
David Tilman,John A. Downing +1 more
TL;DR: This article showed that primary productivity in more diverse plant communities is more resistant to, and recovers more fully from, a major drought and that each additional species lost from our grasslands had a progressively greater impact on drought resistance.

Primary production required to sustain global fisheries
Daniel Pauly,Villy Christensen +1 more
TL;DR: In this paper, the mean of reported annual world fisheries catches for 1988-1991 (94.3 million t) was split into 39 species groups, to which fractional trophic levels, ranging from 1.0 (edible algae) to 4.2 (tunas), were assigned, based on 48 published Trophic models, providing a global coverage of six major aquatic ecosystem types.
