The aim of the survey was to determine the spawning areas and period of the Thames‐Blackwater herring. The objectives of this herring survey were to establish the spawning area of the Thames‐Blackwater herring, to determine the spawning period of the Thames‐Blackwater herring and to ascertain whether there was any relationship between salinity and temperature and spawning area or spawning period.

A total of eleven survey trips were conducted during this period. The dates of each survey trip and trawl conducted are given in Table 4.1. The search pattern used to locate the spawning areas was based on the skippers experience and observations of herring movement prior to each trip, previous research (Wood, 1981), and echo sounder searches of the areas. An overview of all the trawls conducted during this study is provided in Figure 4.1. The vessel tracks and trawls for each survey trip is shown in Figure 4.2 ‐ Figure 4.12 Orsted GIS and Data Coordinator +442078115200 thwal@dongenergy.co.uk pointOfContact EPSG Geodetic Parameter Registry 2022-11-29 revision WGS 84
