GB-Lowestoft: Cefas RFQ for review of methodologies to assess loss of early life stages of fish from entrapment

NOTE: This notice was updated on 21 August 2018 for the following reason: Extension to tendering window - tender now closes on Monday 6th September 2018 at 5pmLoss of early stages of fish due to anthropogenic impacts from e.g. cooling water intakes has long been recognised as a potential issue in assessing environmental impact assessments. The main tool employed for fish loss assessment has been Equivalent Adult values (EAVs) which translate loss of eggs/juveniles into adults using usually generic information from lifetables on survival rates, natural and fishing mortalities.

These lifetables have themselves varying degrees of certainty and evidence to support them. Moreover, the use of EAVs does not consider the role each life stage might have in the local ecosystem and the impact of its removal.

For example, early stages of fish can have an important role as a food item for other organisms.
