Lune, Wyre & Furness Fisheries Advisory Committee 17th January, 1977.

This is the report from the Lune, Wyre and Furness Fisheries Advisory Committee meeting, which was held on the 17th January, 1977. The report contains sections on angling information on the River Lune, fisheries activities, fish stocking, eel fishing in estuarial waters, and Infectious Pancreatic Necrosis which highlights its prevention on imports of salmonid fish and ova. The section on fisheries activities includes salmon and sea trout propagation in Middleton hatchery; fishing conditions/monitoring; and a proposed fish counter in the River Wyre. 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 12th January 1977.

This is the report from the South Lancashire Fisheries Advisory Committee meeting, which was held on the 12th January 1977. The report contains sections on fish mortalities at Henthorn on the 10th July, 1976, fisheries activities, fish stocking, eel fishing on estuarial waters, and infectious Pancreatic Necrosis highlighting its prevention on imports of salmonid fish and ova. The section on fish mortalities looks at fish deaths on the River Ribble caused by a discharge from Clitheroe Sewage Works. The report on fisheries activities includes information on artificial propagation and numbers of fish passing through Waddow Weir, Winckley Hall and Locks Weir between January to November 1976. 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 11th January, 1977.

This is the report from the Eden and District Fisheries Advisory Committee meeting, which was held on the 11th January, 1977. The report contains sections on netting on the Solway Firth, fisheries activities, fish stocking, eel fishing on estuarial waters, and infectious Pancreatic Necrosis. The section on fisheries activities includes general information on the River Eden and Esk; fish transfers; predators; disease; fish mortalities; restocking; and information of Holmwrangle hatchery. The section on Infectious Pancreatic Necrosis looks at this fish disease highlighting its prevention on imports of salmonid fish and ova. 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 & West Cumberland Fisheries Advisory Committee 10th January, 1977.

This is the report from the South and West Cumberland Fisheries Advisory Committee meeting, which was held on the 10th January, 1977. The report contains information on water resources development in West Cumbria, Branthwaite Weir regarding the construction of a fish pass, fisheries activities, fish stocking, eel fishing on estuarial waters, and infectious Pancreatic Necrosis which highlights its prevention on imports of salmonid fish and ova. The section on fisheries activities includes general information on the River Derwent; diseases; fish mortalities; Holmwrangle hatchery and land drainage works. 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.

Fisheries survey of the River Taw 1977

This is the Fisheries survey of the River Taw 1977 report produced by South West Water Authority in 1978. The upper reaches of the River Taw were severely polluted in October 1975 and there was widespread fish mortality. A survey was carried out to assess the recovery of salmonid stocks in the affected areas. Salmon showed a rapid recovery and trout have also recovered well. Both species have been assisted by widespread stocking. Several other species were present. Salmonid and total fish biomass was high. Further stocking of salmon is not recommended and it is also suggested that stocking with trout should be discontinued.

Climatic factors associated with phytoplankton community succession during and after the 1977 drought for the San Francisco Bay-Delta Estuary [abstract]

Principal coordinates analysis and multiple regression analysis were used to determine the environmental factors associated with the decline in phytoplankton production during and after the 1977 drought for the San Francisco Bay-Delta Estuary. Physical, chemical and biological data were collected semimonthly or monthly during the spring-summer between 1973 and 1982 from 15 sampling sites located throughout the Bay-Delta. A decline in phytoplankton community diversity and density during the 1977 drought and subsequent years (1978 through 1981) was described using principal coordinates analysis. The best multiple regression which described the changes in phytoplankton community succession contained the variables water temperature, wind velocity and ortho-phosphate concentration. Together these variables accounted for 61 percent of the variation in the phytoplankton community among years described by principal coordinates analysis. An increase in water temperature, wind velocity and ortho-phosphate concentration within the Bay-Delta, beginning in June 1976 and continuing through 1981, was demonstrated using weighted moving averages. From the strong association between phytoplankton community succession and climatic variables it was hypothesized that the decline in phytoplankton production during and after the 1977 drought was associated with climatic changes within the northeast Pacific.

Uganda Freshwater Fisheries Research Organization Annual Report 1977

Following the collapse of the East African Community on 30th June, 1977 Ugandan fisheries research employees who were stationed in Kenya and Tanzania were recalled by the Uganda Government. The return of these officers strengthened the staff position of the Department. Formally the Headquarters of the East African Freshwater Fisheries Research Organization (EAFFRO), the institution was re-named the Uganda Freshwater Fisheries Research Organization (UFFRO) and the Uganda Government took up the full responsibility for running and maintaining the Department. The Annual report presents activities and achievements during the reporting period 1977.
