PurposeResearch
ObjectivesThe International Bottom Trawl Survey (IBTS) is an internationally coordinated ICES programme. The survey aims to provide ICES assessment and science groups with consistent and standardised data for examining spatial and temporal changes in (a) the distribution and relative abundance of fish and fish assemblages and (b) the biological parameters of commercial fish species for stock assessment purposes.

Objectives

To determine the distribution and relative abundance of pre-recruits of the main commercial species with a view of deriving recruitment indices
To monitor changes in the stocks of commercial fish species independently of commercial fisheries data
To monitor the distribution and relative abundance of all fish species and selected invertebrates
To collect data for the determination of biological parameters for selected species
To collect hydrographical and environmental information
To determine the abundance and distribution of late herring larvae
