    Description: In February 1996 "A Strategy for the Management of Salmon in England and Wales" was launched by the then National Rivers Authority. The strategy concentrates on four main objectives for the management of salmon fisheries in England and Wales. These are primarily aimed at securing the well being of the stock but in doing so will strive to improve catches and any associated economic returns to the fisheries: (i) Optimise the number of salmon returning to homewater fisheries. (ii) Maintain and improve the fitness and diversity of salmon stocks. , (iii) Optimise the total economic value of surplus stocks. (iv) Ensure necessary costs are met by beneficiaries. These four objectives will be addressed through local Salmon Action Plans (SAPs) which will be produced for each of the principle salmon rivers in England and Wales by the year 2001. Each plan will review the status of the stock and the fisheries on a particular river, seek to identify the main factors limiting performance, draw up and cost a list of options to address these, and, consult 0with local interest groups. This report is the draft version of the Salmon Action Plan for the River Lune.

    The River Lune strategic stock assessment survey 1991 with particular reference to salmonids (2021)

    Description: In the past stock assessment surveys were generally reactive in response to a particular problem e.g. a pollution incident and as such were limited in the information they provided. A programme of strategic stock assessment would be more beneficial, providing up to date information on the status and composition of the stock. On a national level this could reveal trends in population dynamics and enable comparisons to be made between key rivers and between regions. The Stock Assessment Task Group (1991) has recommended annual strategic surveys for juvenile salmonids and triennial strategic surveys for coarse fish and non-migratory salmonids. The aim of this pilot study was to gain information on species distribution and their relative abundance within the River Lune catchment, and to compare the findings with the surveys carried out between 1981-1985. This would provide valuable information on the current status of the stock and provide an indication of the resources required to conduct such strategic surveys on other river catchments in the North West Region of the National Rivers Authority.

    The juvenile salmonid populations of the River Lune catchment, 1981 to 1985 (2021)

    Description: The aim of this study was to assess the status of the juvenile salmonid populations of the River Lune and its tributaries. There was special emphasis on juvenile salmon stocks in view of the implementation of a net limitation order in 1980. The number of licensed instruments were reduced as follows: (1) Drift, hang or whammel nets - from 12 to 10 (2) Draft or seine nets - from 3 to 1 (3) Heave or haaf nets - from 4 6 to 2 6 For the purpose of this report, the River Lune system has been divided into 13 subcatchments and these are examined with a view to detecting any trends in the data such as subcatchment productivity, partitioning between salmon and trout nursery streams, and whether the restrictions on salmon fishing had any discernible effects on juvenile salmon productivity. The effect of flow and instream obstructions on salmonid densities are also investigated as these have been shown to be important factors affecting abundance. Throughout the study period a programme of enhancement stocking took place primarily with salmon ova and fry. The possible impact of this on the results of the surveys has been assessed. The distribution and abundance of juvenile salmon was found to be relatively consistent in each of the 13 subcatchments studied over the 1981-1985 period.

    Description: The River Lune was at one time one of the best salmon fisheries in England and Wales with very high catches to both rods and netsmen. During the 1960's, the stock was decimated by the disease Ulcerative Dermal Necrosis which caused a dramatic reduction in catches. Catches have not recovered to pre-disease levels. The target egg deposition rate for the River Lune system which should produce the maximum number of surplus fish returning to the system has been determined at 13.8 million eggs. This will require 4,779 adult salmon to survive to successfully spawn. Under current rates of exploitation, the target egg deposition will occur at a declared rod catch of 1,974 salmon and a net catch of 2,627 salmon. Two automatic fish counters are in operation on the river system. Data from these suggest that, within the measures of compliance, the river has met it's target egg deposition for the last 3 years.

    Description: This study takes a preliminary step towards investigating the reports of poor rod catches of coarse fish in the River Lune. These poor catches and concern over the possible loss of coarse fish from the Lower Lune is investigated, using creel census data from 1991. Historical data is used where available for comparative studies. The conclusion that this report comes to is that there is a problem with the recruitment of coarse fish within the population. Dace, roach and bream all show good growth rates but only poor if any recruitment. Historical investigations suggest that roach and bream may never have successfully recruited without artificial induced conditions. The situation with dace is of more concern as populations in other rivers in Northern England are also in decline, whilst historically they were naturally recruiting.

    Description: This report summarises the findings of a series of electric-fishing surveys carried out at four sites on the River Ribble from September 1997 to September 1998. The aims of these surveys were to assess the impact on juvenile salmonids of a pollution incident involving Synthetic Pyrethrin (SP) that occurred near High Birkwith I (SD 802 767) in September 1997.One of these sites was 2.65km upstream of the pollution whilst the remaining three were at varying distances downstream. Data was collected during surveys of the River Ribble in 1992, 97 and 98. The 1997 and 1998 surveys were carried out specifically to monitor for any possible effects of the SP discharge.Data are shown as grades derived from the National Fisheries Classification scheme (NFC). Results are given for the four salmonid life stages; 0+ trout, 〉0+ trout, 0+ salmon, 〉0+ salmon and also Total Salmonids.

    Description: The stock assessment task group report (1991) mentions that fish counters could play a key role in providing data on the size of the adult stock, and in particular the migratory salmonid stock. This report assesses the performance of the 'logie' fish counter at Forge Weir on the River Lune. Using video surveillance, a total of 1137 hours time lapse and 15 hours real time were used for validation purposes. This report looks at materials and methods, counting accuracy, sizing ability and environmental conditions, performance across the electrode array and salmonid swimming speed.
