TL;DR: Using a stochastic food-web model for a large marine ecosystem hosting a commercially important cod stock, the history of the stock is reconstructed and it is demonstrated that in hindsight the collapse could only have been avoidable by adapting fishing pressure to environmental conditions and food- web interactions.
Abstract: Worldwide a number of fish stocks have collapsed because of overfishing and climate-induced ecosystem changes. Developing ecosystem-based fisheries management (EBFM) to prevent these catastrophic events in the future requires ecological models incorporating both internal food-web dynamics and external drivers such as fishing and climate. Using a stochastic food-web model for a large marine ecosystem (i.e., the Baltic Sea) hosting a commercially important cod stock, we were able to reconstruct the history of the stock. Moreover we demonstrate that in hindsight the collapse could only have been avoidable by adapting fishing pressure to environmental conditions and food-web interactions. The modeling approach presented here represents a significant advance for EBFM, the application of which is important for sustainable resource management in the future.

TL;DR: In this paper, the authors found that recreational fishing is increasingly as important as commercial harvest to populations of popularly fished marine recreational species in the US and that the increasing importance of recreational fishing was a general trend of marine fisheries.

TL;DR: The marine fisheries sector in India has witnessed a phenomenal growth during the last five decades both quantitatively and qualitatively as mentioned in this paper, and this increase is the result of improvements in the harvesting methods, increase in the fishing effort and extension of fishing into relatively deeper regions.
Abstract: The marine fisheries sector in India has witnessed a phenomenal growth during
the last five decades both quantitatively and qualitatively. The subsistence fisheries
during the early 50’s produced about 0.5 million tonnes annually. Currently, the
total production is about 2.7 million tonnes. This increase is the result of
improvements in the harvesting methods, increase in the fishing effort and extension
of fishing into relatively deeper regions. The increased effort over time and space
is the consequence of ever-increasing demand for marine food both from external
and internal markets. This phenomenal growth also brought in imbalances in the
exploitation across the regions and among the resources. Besides, with production
levels for most of the commercially important resources showing signs of approaching
saturation levels, inter sectoral conflicts increased due to competition to exploit the
common resource. Fleet size and operations underwent quantitative and qualitative
change. Traditional boats are being increasingly motorised and the mechanised
sector operating with trawlers and gillnetters are resorting to multi-day fishing, thus
contributing to increased fishing pressure. The situation thus calls for an appraisal
of the status of the resources on a regional and all India basis, taking into consideration
the scientific database developed over a period of about half a century to enable
formulate suitable strategies of exploitation and management.

TL;DR: In this article, the authors proposed a precautionary approach to fisheries management together with the development of indicators and reference point values that trigger management actions, and their adoption within the framework of the same conventional models used to assess fish stocks could introduce another degree of complexity into existing models.

TL;DR: In this article, an age-structured model based on an Atlantic cod population that included more realistic reproductive factors was used to assess the usefulness of marine reserves to prevent overexploitation of migrating fish.
