Recent studies of the distribution and abundance of grey seals (Halichoerus grypus) in north Norway, and their possible influence on parasitic infestations in fish
(ICES CM Documents;1991/N:2, Working paper, 1991)Distributions of grey seals Halichoerus grypus were studied during aerial and ground surveys in North Norway. Surveys were conducted from Lofoten to the Soviet border during the moult (March-April, Finnmark) and breeding ... -

Scale damage and survival of cod and haddock escaping from a demersal trawl
(ICES CM Documents;1991/B:44, Working paper, 1991)Cod (Gadus morhua L.) and haddock (Melanogrammus aeglefinus L.) escaping through the meshes of a cod-end (135 mm diamond meshes) or through a metal grid sorting device mounted in the foremost part of the cod-end, were ... -
The recovery of the Barents Sea capelin (Mallotus villosus) from a larval point of view
(ICES CM Documents;1991/H:13, Working paper, 1991)The recovery of the Barents Sea Capelin is studied with larval surveys in the period 1986-91. Very few larvae were found in 1986,1987 and 1988, but the abundance of capelin larvae increased from 1989 back to the ... -
Report of the Workshop on Identification of Fish Farm Escapees and Wild Salmon [Trondheim, 11- 13 February, 1991]

Influence of climate on recruitment and migration of fish stocks in the North Sea
(ICES CM Documents;1991/H:12, Working paper, 1991)For several decades one of the prime targets within fishery science has been to be able to understand and explain the great variability in the success of survival from egg to mature fish. One of the reasons why such effort ... -
Swimming speed of spent Norwegian spring spawning herring
(ICES CM Documents;1991/H:9, Working paper, 1991)In March 1990 spent Norwegian spring spawning herring were tagged on the spawning grounds off Karmøy in southwestern Norway. 37 of these tagged herring were recaptured approximately 40 hours later. The recapture took place ... -
Report of a joint Norwegian-Soviet acoustic survey on blue whiting, spring 1991
(ICES CM Documents;1991/H:4, Working paper, 1991)During spring 1991 the second Norwegian-Soviet joint survey on the blue whiting spawning stock was carried out. The result of a ship-to-ship calibration of the acoustic instruments allowed a 1:1 relationship between the ... -
An evaluation of survey design for estimating the food consumption by fish
(ICES CM Documents;1991/D:15, Working paper, 1991)The effect of survey design on the precision of estimates of average fish stomach contents is examined. The contribution to the total variance from within and between tow variability in stomach contents is evaluated, ... -
Assigning values of target strength and equivalent beam angle in acoustic surveys of fish
(ICES CM Documents;1991/B:34, Working paper, 1991)Contrary to popular opinion, the equivalent beam angle (~) is not determined solely by the transducer directivity. Rather, like the target strength TS, it also depends on the scattering properties of the target fish, but ... -
School geometry measurements using a sonar accuracy and an algorithm for school detection
(ICES CM Documents;1991/B:36, Working paper, 1991)The accuracy of geometric measurements of schools, using horizontal guided single-beam or multi-beam sonar, is simulated. For both types of sonars, the accuracy is dependent of horizontal beam-width and range. As multiple ... -
Report of the Working Group on Fishing Technology and Fish Behaviour [Ancona, 22- 24 April, 1991]
(ICES CM Documents;1991/B:28, Working paper, 1991) -
Monitoring changes in abundance of gadoids with varying availability to surveys
(ICES CM Documents;1991/G:76, Working paper, 1991)The use of scientific survey data for assessing abundance of commercially important fish stocks has become a managerial necessity in many regions. Errors and bias in estimates from such surveys may thus have great economic ... -
