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.

This is the report from the South and West Cumberland Fisheries Advisory Committee meeting, which was held on the 8th January, 1979. It covers information on Ravenglass Salmon Garth, South West Cumbria and opencast coal workings. The section on the report by the area fisheries officer on fishing activities includes river conditions and fishing, and an update on Holmwrangle Hatchery which includes stock numbers and fish distribution. Fish disease and biological work undertaken on fish in Ennerdale Lake are also added, as well as numbers of salmon and sea trout stripping from the River Marron for Holmwrangle Hatchery. 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.
