Effective fisheries management instrumental in improving fish stock status. [PDF]

Proc Natl Acad Sci U S A, 2020
Significance This article compiles estimates of the status of fish stocks from all available scientific assessments, comprising roughly half of the world’s fish catch, and shows that, on average, fish stocks are increasing where they are assessed.

Eco-label conveys reliable information on fish stock health to seafood consumers. [PDF]

PLoS One, 2012
Concerns over fishing impacts on marine populations and ecosystems have intensified the need to improve ocean management. One increasingly popular market-based instrument for ecological stewardship is the use of certification and eco-labeling programs to

Using otoliths for fish stock discrimination: status and challenges

Acta Ichthyologica et Piscatoria, 2021
Otoliths are calcified structures and the information contained within their chemistry or shape can be used to infer life history events, migration patterns, and stock structure of a fish population.

Fish Stock Assessment for Data-Poor Fisheries, with a Case Study of Tropical Hilsa Shad (Tenualosa ilisha) in the Water of Bangladesh

Sustainability, 2021
The anadromous tropical Hilsa shad formed the largest single-species fishery in Bangladesh, making the highest contribution to the country’s total fish production (14%) and nearly 83% of the global Hilsa catch in 2018. However, increased fishing pressure

Ecology: Managing Evolving Fish Stocks [PDF]

Science, 2007
Evolutionary impact assessment is a framework for quantifying the effects of harvest-induced evolution on the utility generated by fish stocks.

The potential of video imagery from worldwide cabled observatory networks to provide information supporting fish-stock and biodiversity assessment

ICES Journal of Marine Science, 2020
Seafloor multiparametric fibre-optic-cabled video observatories are emerging tools for standardized monitoring programmes, dedicated to the production of real-time fishery-independent stock assessment data.

Assessing the Fish Stock Status in Lake Trichonis: A Hydroacoustic Approach

Water, 2020
Fish stock monitoring is an important element for the sustainable management of inland water resources. A scarcity of data and the lack of systematic monitoring for Lake Trichonis precludes an up-to-date assessment.

Regulation of fish stocks without stock–recruitment relationships: The case of small pelagic fish [PDF]

Fish and Fisheries, 2020
AbstractSmall pelagic fish lack clear stock–recruitment relationships. This is a problem because such relationships are taken to be the primary descriptors of density dependence, responsible for regulating population density. In this paper, we show that small pelagic fish species, anchovy (Engraulis spp., Engraulidae), living in a stochastic ...

Inclusion of ecosystem information in US fish stock assessments suggests progress toward ecosystem‐based fisheries management

ICES Journal of Marine Science, 2018
&NA; The appetite for ecosystem‐based fisheries management (EBFM) approaches has grown, but the perception persists that implementation is slow. Here, we synthesize progress toward implementing EBFM in the United States through one potential avenue ...

A decline in primary production in the North Sea over 25 years, associated with reductions in zooplankton abundance and fish stock recruitment

Global Change Biology, 2018
Phytoplankton primary production is at the base of the marine food web; changes in primary production have direct or indirect effects on higher trophic levels, from zooplankton organisms to marine mammals and seabirds.
