Langcliffe hatchery investigations 1982 [on River Ribble near Settle]

Langcliffe hatchery investigations looks at fish mortalities for salmon (fry), sea trout, brown trout and rainbow trout, and explores the River Ribble's water supply.

Electrofishing survey of the River Calder and its tributaries - April 1978.

An electrofishing survey was undertaken in the period April 24th - 28th as part of the detailed biological study of the Calder Catchment being carried out by this department in early 1978. The sites to be fished were selected to indicate broadly the fishing status of the major sections of the main river and its larger tributaries and by no means intended to describe the fishing status of the whole catchment in detail. The results on the distributions of fish species are discussed, in general, in relation to the major polluting influences on the catchment. The results of the second survey are given and discussed separately in Appendix I.

Statistiques de la pêche collective en Lagune Ebrié (1978-1979)

A first treatment of the statistical data of 1978 and 1979 on the collective fishing showed a decrease of total catches in the Ebrié Lagoon. The same diminution was found in the amount of smoked-fish collected in two different places of the lagoon. This fall is due to a smaller effort in the lagoon of the purse-seines in the Abidjan area and a decrease of the catches per unit of effort.

Biological Analysis of Two Management Options for the Atlantic Menhaden Fishery

Biological implications of two managment options (the closed corridor and the recommended shortened season (Option 7) options) for the Atlantic menhaden, Brevoortia tyrannus, fishery are reported based on purse-seine landings and port sampling data from 1970 to 1984 and captain's daily fishing reports from 1978 to 1982. Large catches of age-O menhaden raise concern for growth overfishing. Area-specific yield-per-recruit analyses are used to investigate the biological consequences of these management options. The closed corridor option indicates coastwide gains in yield-per-recruit ranging from 0.3 to 7.2% depending on changes in fishing activity with most areas showing gains. The shortened fishing season indicates coastwide gains in yield per recruit ranging from O. 4 to 10.2% depending onf ishing year with most geographic areas showing gains. The shortened fishing season option offers the greatest gains when large numbers ofy oung menhaden would be caught late in the fishing year, while gains from the closed corridor option depend on how the fishing fleet responds to that management plan. The shortened season offers greater potential coastwide gains to the fishery, but also may result in greater losses to the North Carolina fall fishery. The analytical approach is applicable to the management of other coastal migratory fish stocks that fall under the Atlantic States Marine Fisheries Commission or other interstate management groups.

South & West Cumberland Fisheries Advisory Committee 9th January, 1978

This is the report from the South and West Cumberland Fisheries Advisory Committee meeting, which was held on the 9th January, 1978. It covers information on water resource development for West Cumbria which includes details on the River Derwent and Ennerdale schemes, fisheries income and expenditure, licence duties, Eskett Quarries and radioactive discharge in relation to fishery interests. It also looks at the report by the area fisheries officer on river conditions and fishing, Holmwrangle Hatchery and stocking. Included in this report is a note on survey work carried out on Braystones Tarn, resources and the collection of fish for hatcheries. 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 & District Fisheries Advisory Committee 10th January, 1978

This is the report from the Eden and District Fisheries Advisory Committee meeting, which was held on the 10th January, 1978. It covers information of fisheries income and expenditure, licence duties, regional water resources study, salmon fishing, radioactive discharge in relation to fishery interests and a brief mention about the possibilities of opening Castle Carrock reservoir for public angling. It also includes the report by the area fisheries officer on river conditions and fishing, Holmwrangle Hatchery and stocking. Included in this report is a note on the survey work carried out on the Upper Eden and Eamont regarding brown trout, the collection of fish for hatcheries, Redd counting and the transfer of coarse fish. 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.

South Lancashire Fisheries Advisory Committee 11th January, 1978

This is the report from the South Lancashire Fisheries Advisory Committee meeting, which was held on the 11th January, 1978. It covers information of fisheries income and expenditure, licence duties, regional water resources study, Worthington reservoirs regarding fishery regulations and radioactive discharge in relation to fishery interests. It also includes the report by the area fisheries officer on river conditions and fishing for salmon, sea trout, brown trout and coarse fish, numbers of migratory fish movements at Waddow Weir, Winckley Hall and Locks Weir, and Langcliffe Hatchery. Included in this report is also a brief note on fish disease in salmon in the Ribble and Hodder, and the improvement of Stock Beck after the pollution incident. 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.

Lune Wyre & Furness Fisheries Advisory Committee 16th January, 1978

This is the report from the Lune, Wyre and Furness Fisheries Advisory Committee meeting, which was held on the 16th January, 1978. It covers information on fisheries income and expenditure, licence duties, regional water resources study, fish stocks in the River Leven, Skerton fishery and radioactive discharge in relation to fishery interests. It also includes investigations for future water supplies to South West Cumbria and the report by the area fisheries officer on river conditions and fishing for salmon, sea trout, and coarse fish, numbers of fish movements at Haverthwaite, Broadraine and Forge Weir fish monitoring station. Included in this report is also work at Middleton Hatchery, a brief note on fish disease in migratory fish in the Lune and Kent, and net catch figures for the year for the Rivers Lune, Kent, Leven and Duddon. 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.
