This is the Kendal, Lancaster and Preston canal fishery produced by Lancashire River Authority in 1970. The Kendal-Lancaster-Preston canal commenced at Stainton in Westmorland and terminated on the outskirts of Preston. Fishing in the canal with rod and line was controlled by the Northern Anglers’ Association. In the early 60’s anglers, had complained about, the extremely low numbers of fish that had been caught in the canal and various opinions had been expressed concerning the alleged shortages o f fish. Since 1967, in an endeavour to meet the fish re-stocking demands of the Association, 50,000 freshwater fish of different species had been introduced by the Lancashire River Authority, but catches had not increased. In 1969 was agreed by the Northern Anglers’ Association to carry out a study of the fish populations throughout the whole length of the canal and the chemical quality of the water analysed. This report is not produced as a scientific dissertation, but rather as a means of imparting to members of the Northern Anglers’ Association the fish potential available to them in their endeavours to catch fish.

There has been a perception of increasing river channel instability in north west rivers and the River Lune in particular in recent decades. This has been attributed variously to: (a) long-term trends in precipitation-runoff regime; (b) changes in land-use such as moor-draining and sub-soil draining such that the river is more flashy than previously, and (c) a change in the magnitude-frequency relationships of flow such that high discharges are occurring with increased frequency. Resources are available in the form of rainfall and runoff records, archived information on channel planform, land use statistics and local engineering experience which have not been jointly and fully evaluated. Effective interpretation of the nature of channel change through time with respect to this resource may enhance the Environment Agency's ability to manage the river channel efficiently in the future and will aid the development of effective policy. The results of this study will for the first time, provide robust guidance with respect to long-term channel adjustment and the appropriate management options. The research provides suggestions as to how policy might be developed taking account of other pertinent factors.

All species of fish are able to propagate and maintain their numbers provided that no adverse influence occurs to change the compatible environment, the salmon is no exception. Propagation of fish by artificial means has long been a subject of discussion amongst fishery workers and views have been expressed (both favourable and unfavourable) on the merits of the various methods employed. In an attempt to discover whether artificial propagation was necessary and also to find the best methods of propagation to adopt in the various rivers, a phased programme of investigation into natural spawning efficiency and the results obtained by various methods of artificial propagation was started in the Lancashire River Board area during 1957. The object being to seek information on: (1) The survival of ova from natural spawnings to the eyed and alevin stages. (2) The population density of feeding fry (from natural spawnings) at various intervals of development. (3) The viability of green ova and eyed ova- when planted artificially. (4a) The survival to 0+ parr from implants of eyed ova unfed fry and fed fry. (4b) Populations per unit area of 0+ parr from various planting densities of eyed ova, unfed fry and fed fry. Sampling stations were selected on the Rivers Ribble, Lune and Wyre watersheds for the purpose of marking and examination of natural salmon redds.

This brief reports highlights the significance of scale readings of salmon. The reasons for colour change of scales and scale rings are briefly explained. Scale readings of salmon fry from the River Lune in the north west of England are presented. The salmon was captured in 1957/58.

This is the report from the South Lancashire Fisheries Advisory Committee meeting, which was held on the 15th October 1975. The report contains sections on planning study for the post 1981 period, reports on fisheries activities, land drainage representation on local committees, proposed new byelaws and fishing licence duties. The section on fisheries activities are reported by area fisheries officers and looks at poaching, Langcliffe and Middleton hatcheries management, number/causes of fish mortalities and biological work carried on Colne Water and Lancaster Canal. 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.
