The present data refer to sand eel fishing in Esbjerg in May and June (the peak season for sand eel fishing) 2000. The sand eel is caught in the North Sea by trawling with fishing vessels ranging from 150 to 600 BT (brutto ton). The fishing vessels are generally old (average 25 to 30 years), but diesel engines are generally modern and well maintained. The sand eels are stored in the trunk of the fishing vessels and the fish are unloaded in the harbour without treatment.
According to the national law, Danish fishermen are reporting diesel consumption and catch size for every fishing event. The revision firm "Revision Vestkysten" is currently collecting this information and the company has served as data supplier. The data collection covers 12 fishing vessels and 76 fishing events.
Average diesel, ice and lubricant oil consumption per kg of catch have been
Diesel consumption and air emissions due to steaming to and from the harbour as well as the fishing operation are included.
Sand eel catching technology is quite uniform in Denmark. However, important factors for diesel consumption such as 1) sizes of fishing vessels, 2) distances to fishing site and 3) fishing depth varies geographically. The present dataset represents 18.3 % of sand eel caught in Esbjerg in May to June 2000, 12.2% of sand eel caught in Esbjerg on a yearly basis and about 5% of sand eel caught in Denmark. Hence, the data set is very representative to local conditions in Esbjerg whereas the representativity on a countrywide scale is unknown. Refer to wild fish for data on a industrial fish fishery on a national scale.
Diesel consumption for sand eel catching in Esbjerg in May and June has been compared with diesel consumption for industrial fish catching in Denmark all the year. The data recorded in the present datasheet are 20% lower than the national data. The differences can be explained by the high efficiency of sand eel fishery in May and June.
