Targeted fisheries on these spawning aggregations is conducted during that period and contributes significantly to the overall fishing mortality of the stock and especially to the reduction in numbers of adult fish that can successfully reproduce.

'spawning stock biomass' means an estimate of the mass of the fish of a particular stock that reproduces at a defined time, including both males and females and fish that reproduce viviparously;

(3a) Union policy and legislation in relation to bluefin tuna should be consistent with Directive 2008/56/EC of the European Parliament and of the Council of 17 June 2008 establishing a framework for community action in the field of marine environmental policy (Marine Strategy Framework Directive) and Commission Decision 2010/477/EU of 1 September 2010 on criteria and methodological standards on good environmental status of marine waters, which require Member States to take action to ensure that, by 2020, at the latest, the spawning stock biomass of all populations of commercially exploited fish, including bluefin tuna, is at or above th ...[+++]e spawning stock biomass associated with maximum sustainable yield.

Wild Atlantic breeding stock salmon are being intercepted by driftnet fishermen as the salmon try to make their way to their natural habitat rivers.

The main effect of mortality on the target species is a reduction in the average age and size of fish in the stock, and hence a reduction in the overall stock biomass, particularly the spawning stock biomass.

In the vicinity of certain sources (e.g. effluents of water treatment plants) and in the most contaminated areas this exposure is causally linked with effects on reproductive organs, which could have implications for fish populations.
