The Impact of Abbey Mill Pit on the Migratory Pathways of Glass Eels
The impact of the weirs on the migratory pathways of glass eels and juvenile eels at the tidal limits of the Avon. Abbey Mill Pit and Stanchard Pit 2025.
Mark and Capture Study 2024 Glass Eel Season on Severn
A mark and recapture exercise to estimate population size and exploitation rate was carried out using the same methodology as used in 2020, 2022 and in 2023.
Glass Eel Tidal Population Severn Estuary 2024
To develop a fishery independent methodology to measure pre fishing glass eel recruitment in the Severn Estuary.
To validate some of the existing EDF data set that the mean glass eel densities glass eels per from the Open Water pelagic surveys in February/March 2012, February/March 2013 and April 2013.
Mark and Capture Study 2023 Glass Eel Season on Severn
Mark release recapture trials were again conducted to determine the exploitation rate of glass eel by handheld dip nets in the Severn Estuary in the spring of 2023.
Glass Eel Tidal Population Severn Estuary 2023
Our survey was done over a period between February 15th and 3rd March 23 investigating variability in eel abundance between the two years and within a recruitment season.
2022 Glass Eel Restocking Report.
Restocking of the River Severn.
Mark and Capture Study 2022 Glass Eel Season on River Severn.
An analysis of recruitment, exploitation and escapement targets.
A Trial to Estimate Glass Eel Exploitation in the River Severn – 2020
Three trials were conducted to establish the exploitation rate of glass eel by a fishery on the River Severn that uses a traditional hand dip net method; between March 25th and April 8th; between April 22nd and May 13th and between May 4th and May 13th.
Investigation of failure of migrating juveniles to cross Tewkesbury weir.
Juvenile eels (Anguilla Anguilla) were observed ascending the weir at Tewkesbury on the River Severn. A closer investigation of the movement of these juveniles revealed that the migration was largely unsuccessful due a number of obstacles.
There is evidence as early as 1850 of systems in place to control flooding and improve drainage on the River Severn.
The Impact of Weirs at the Tidal Limits of the Severn and Avon on the Migratory Pathways
The weirs at Tewkesbury represent the first significant barrier on the Severn and Avon for glass eels and juveniles. Some practical observations. 2025.
Estimation of glass eel (Anguilla anguilla L.) exploitation in the Severn Estuary.
Mark release recapture trials were conducted to determine the exploitation rate of glass eel by handheld dip nets in the Severn Estuary in the spring of 2020. This paper has now been peer reviewed and published in the Journal of Fisheries Management and Ecology (Wiley).
Estimation of glass eel recuitment on the River Wye
The study was undertaken on spring tides over a period from March 26th to May 12th 2021. The site chosen was at the lowest point of the glass eel fishery on the River Wye at Brockweir, 10 kilometres inland from confluence of where the River Wye joins the Severn estuary.
Investigation of failure of glass eels to migrate through tidal defence barrier on the River Frome
A simple trial at a tidal flap gate showed that glass eel passage was notpossible during the tidal phase of active glass eel migration.
An experimental study of the swimming velocity of glass
eels
A quantitative assessment of maximum swimming velocities of late season pigmented glass eels was undertaken to investigate the probability of glass
eels being able to undertake upstream migrations through flap/door type flood defence mechanism.
Primary Barriers to Glass Eel Migration
The Red Barn Dyke Glass Eel Fishery – Applicability Review
The proper management of a species within a national system of river basin districts requires validated data for the effectiveness of any fishery that could affect the recruitment.
