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.

Harvesting and economic patterns in the artisanal Octopus mimus (Cephalopoda) fishery in a northern Chile cove

TL;DR: In this paper, the authors analyzed intra-and inter-annual harvesting and economic patterns of the cephalopod octopus mimus (pulpo) artisanal fishery at Caleta Coloso cove, Antofagasta, northern Chile, between 1991 and 1996.

The influence of troughs and crests of ripple marks on the structure of subtidal benthic assemblages around rocky reefs

TL;DR: In this paper, the authors tested the hypothesis that the small-scale topography caused by ripples in sediment would affect benthic macrofaunal assemblages and found that ripple marks were significantly wider and taller close to than far from reefs.

Mitigating killer whale depredation on demersal longline fisheries by changing fishing practices

TL;DR: In this paper, the authors identify fishing practices that could reduce odontocete depredation, with a focus on killer whales (Orcinus orca) interacting with Patagonian toothfish (Dissostichus eleginoides) longliners off the Crozet islands.

The importance of recruitment for the production dynamics of stream-dwelling brown trout (Salmo trutta)

TL;DR: The objective was to highlight the role of recruitment for production dynamics of stream brown trout (Salmo trutta) by analysis of 51 cohorts hatched in 1986 and 1999 at four sites of Rio Chaballos.

On the experimental study of the flow around a fishing net

TL;DR: The aim of a better understanding of the flow in presence of a net and a catch is to determine and to analyze the flow over a rigid cod-end in two configurations: with a closed and an open net entrance.

Biodiversity and stability in grasslands

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

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.
