| The necessity to move from a traditional fishery management to an ecosystem approach is now acknowledged. Indicators are required to support the development of this approach. For example, community indicators have been proposed to assess the impact of fishing. We tested here the applicability of one such community indicator, the abundance-biomass comparison (ABC method), as a measure of the impact of bottom trawling (years of sampling: 2001 and 2003) on the benthic invertebrates-typically starfishes, crabs, squat lobsters, shrimps and large hard-shelled molluscs-of "Grande Vasiere", a major French fishing zone, in the Bay of Biscay. The ABC method is generally used as an impact indicator for different types of physical, biological and anthropogenic... |

| Since 1994, Mediterranean research organisations have carried out yearly standardized bottom trawl surveys along the coasts of the Mediterranean Sea from Gibraltar to the Aegean Sea (Medits surveys). A dynamic indicator-based approach to the assessment of multi-stock fisheries has been applied to the data series obtained from these surveys by an international working group involving all the scientific teams contributing to the data collection process. The application was done according to the 13 GFCM geographical sub-areas sampled by the Medits surveys. While reference points for a lot of fished populations and community indicators are seldom available, reference directions are well established for some indicators, giving guidelines for fishery management.... |

| Marine biota are redistributing at a rapid pace in response to climate change and shifting seascapes. While changes in fish populations and community structure threaten the sustainability of fisheries, our capacity to adapt by tracking and projecting marine species remains a challenge due to data discontinuities in biological observations, lack of data availability, and mismatch between data and real species distributions. To assess the extent of this challenge, we review the global status and accessibility of ongoing scientific bottom trawl surveys. In total, we gathered metadata for 283,925 samples from 95 surveys conducted regularly from 2001 to 2019. We identified that 59% of the metadata collected are not publicly available, highlighting that the... |
