Lune, Wyre & Furness Fisheries Advisory Committee 3rd July, 1978

This is the report from the Lune, Wyre and Furness Fisheries Advisory Committee meeting, which was held on the 3rd July, 1978. It covers information on the monitoring of radioactivity in migratory fish, fishing offences and prosecutions, the income from sale of rod and line licences, the review of discharge consent conditions, illegal netting, the Morecambe and Heysham sewerage scheme and fish counting work. It also covers the report by the area fisheries officer on river conditions and fishing for Lune, Furness, Wyre and tributaries. Also covered in the report is information on migratory fish movements, fish monitoring stations, Middleton hatchery, fish mortalities, fish diseases, biological work and stocking numbers of brown trout, rainbow trout and coarse fish by the Angling Associations. The Fisheries Advisory Committee was part of the Regional Water Authorities, in this case the North West Water Authority. This preceded the Environment Agency which came into existence in 1996.

Eden and District Fisheries Advisory Committee 3rd April, 1979

This is the report from the Eden and District Fisheries Advisory Committee meeting, which was held on the 3rd April, 1979. It includes the information on the meeting about the possible reduction of haaf netting on the Solway Estuary. Also covered is the report by the area fisheries officer on fisheries activities which comments on river conditions and fishing for salmon, sea trout and coarse fish and an update on Holmwrangle hatchery including mortalities due to water quality and gill infections in brown trout. It also looks at fish disease, research work and data of monthly salmon and migratory trout catches on rod, line, nets and fixed engines for the 1978 season. The Fisheries Advisory Committee was part of the Regional Water Authorities, in this case the North West Water Authority. This preceded the Environment Agency which came into existence in 1996.

Regional Fisheries Advisory Committee 3rd February, 1986

This is the report from the Regional Fisheries Advisory Committee meeting, which was held on the 3rd February, 1986. The report contains sections on Fishing Licence Duties 1987, the provisions of the Police and Criminal Evidence Act 1984, the Salmon Bill, and Fisheries Byelaws. The Fisheries Advisory Committee was part of the Regional Water Authorities, in this case the North West Water Authority. This preceded the Environment Agency which came into existence in 1996.

Regional Fisheries Advisory Committee 3rd November, 1986

This is the report from the Regional Fisheries Advisory Committee meeting, which was held on the 3rd November, 1986. The report contains sections on a proposed Haaf Net Limitation order, Salmon and Freshwater Fisheries in the Solway Firth, Ullswater Freshet pumping station, and Authority investigations into Acidity Problems in North West water. Also included is information on commercial salmon fishing in the River Lune and coarse fish close season in enclosed waters. The Fisheries Advisory Committee was part of the Regional Water Authorities, in this case the North West Water Authority. This preceded the Environment Agency which came into existence in 1996.

Reynolds number influence on turbulent blocking effects of a rigid plane boundary (3rd report, direct numerical simulation on wall blocking effects for anisotropic turbulence)

The Reynolds number influence on turbulent blocking effects by a rigid plane boundary is studied using direct numerical simulation (DNS). A new forcing method proposed in the second report using Townsend's "simple model eddies" for DNS was extended to generate axisymmetric anisotropic turbulence. A force field is obtained in real space by sprinkling many space-filling "simple model eddies" whose centers are randomly but uniformly distributed in space. The axes of rotation are controlled in this study to generate axisymmetric anisotropic turbulence. The method is applied to a shear-free turbulent boundary layer over a rigid plane boundary and the blocking effects for anisotropic turbulence are investigated. The results show that stationary axisymmetric anisotropic turbulence is generated using the present method. Turbulence intensities near the wall showed good agreements with the rapid distortion theory (RDT) for small t (t ≪ TL), where TL. is the eddy turnover time. The splat effect (i. e. turbulence intensities of the components parallel to the surface are amplified) occurs near the boundary and the viscous effect attenuates the splat effect at the quasi steady state at low Reynolds number as for Isotropic turbulence. Prandtl's secondary flow of the second kind does not occur for low Reynolds number flows, which qualitatively agrees with previous observetion in a mixing-box.

Aquatic ecology monitoring: water quality, fish, fish catch and parasites: monitoring no.4, 3rd-7th April 2009

The survey covered by this report was undertaken between 3rd and 7th April 2009 as a follow-up on the during construction surveys. Two pre-construction baseline surveys were undertaken in April 2000 and April 2006. During the construction phase which started in 2007, three surveys including the current one have been undertaken i.e. in September 2007, April 2008 and the present one, in April 2009. Unlike in all previous surveys in which monitoring was conducted at one transect upstream and three downstream transects, in the current survey, two transects, one upstream and the other,downstream of the BHPP were sampled with emphasis on the following aspects: 1. water quality determinants 2. biology and ecology of fishes and food webs 3. fish stock and fish catch including economic aspects of catch and 4. sanitation/vector studies (bilharzias and river blindness)
