TL;DR: In this paper, the authors summarize the knowledge of recent changes in cod biology and ecosystem conditions, describe the subsequent challenges for stock assessment, and highlight the key questions where answers are urgently needed to understand the present stock status and provide scientifically solid support for cod management in the Baltic Sea.

TL;DR: The eastern Baltic cod stock has recently started to recover, after two decades of severe depletion, however with unexpected side effects, the stock has not re-occupied its former wide distribution range, but remains concentrated in a limited area in the southern Baltic Sea.

TL;DR: Koster et al. as mentioned in this paper studied fish stock development in the Central Baltic Sea (1976-2000) in relation to variability in the environment and found that the variability was positively associated with fish stock growth.

TL;DR: The approach takes the single-species advice for each species in the fishery as a starting point, then attempts to resolve it into consistent catch or effort advice using fleet-disaggregated catch forecasts in combination with explicitly stated management priorities for each stock.

TL;DR: In this paper, the performance of the EU long-term management plan for cod stocks, in force since 2009, is analyzed focusing on the human and institutional factors, and a novel instrument allowing Member States to ‘buy back’ or increase fishing effort for fleet segments engaged in cod-avoidance measures.
