Acoustic sampling volume for cod
(ICES CM Documents;1989/B:5, Working paper, 1989)This is expressed through the effective equivalent beam angle * for cod as represented by measurements of the tilt angle dependence of target strength. The functional form of * is approximated for each of several behaviour ... -

Calibration reflector
(ICES CM Documents;1989/B:4, Working paper, 1989)Calibration of scientific echo sounders and integrators entails, inter alia, measurement of the dynamic range. This can be done by repeating on-axis measurements of echoes from each of two different standard targets. ... -
Bergen Echo Integrator: An Introduction
(ICES CM Documents;1989/B:9, Working paper, 1989)The design of a new echo integrator system is outlined. The B.E.I. is based on preprocessed data from the new SIMRAD EK500 scientific acoustic measurement system. Raw data are displayed and interpreted on a graphics ... -
Trends in growth and reproductive parameters of Barents Sea harp seals
(Working paper, 1993)Data from reproductive organs of Barents Sea harp seals Phoca groenlandica with corresponding age determinations have been analysed in combined samples collected during three periods: 1963-1972, 1976-1985 and 1990-1993. A ... -
Summary of 1991 aerial and visual surveys to estimate harp seal production in the Greenland Sea
(Working paper, 1993) -
Updated simulations of development in stock size and pup production for harp seals in the Greenland Sea 1946-1993, and corresponding catch and stock projections.
(Working paper, 1993)Applying the same model as in Ulltang (1989a, b), the development in stock size and pup production of the Greenland Sea hatp seal population is simulated for the period 1946-1993, assuming a pup production of 50000 in 1991 ... -
Update of mark-recapture estimates of harp seal pup production in the Greenland Sea
(Working paper, 1993) -
Summary of methods for measuring fish target strength
(ICES CM Documents;1988/B:4, Working paper, 1988)Methods for measuring fish target strength are intercompared. The consistency of results obtained on the same or related species by different methods is noted. -
Report of the Arctic Fisheries Working Group [Copenhagen, 14 -24 September, 1987]

Estimates of stock size of northeast Arctic cod and haddock, "Sebastes mentella" and "Sebastes marinus" from survey data, winter 1988
(ICES CM Documents;1988/G:43, Working paper, 1988)An acoustic survey and a bottom trawl survey for cod and haddock were carried out in the Barents Sea during the winter 1988. The fish still had the westerly distribution established in the previous year, but the echo ... -

Avoidance reactions of herring to a survey vessel, studied by scanning sonar
(ICES CM Documents;1988/H:46, Working paper, 1988)The behavioural response of a shallow herring layer to a steaming vessel has been studied by the use of a high-resolution scanning sonar technique. When the vessel was completely darkened, no significant reaction important ... -
Stimulated growth and safeguarding of the ICES oceanographic data bank
(ICES CM Documents;1988/C:16, Working paper, 1988)During a number of years there has been a consent to build up and increase the ICES oceanographic data base to the benefit of the member countries. In parallel to this there has been an increasing demand for ICES to ... -
Report on an acoustic survey for mackerel in the North Sea, Skagerrak and Kattegat in July - August 1987
(ICES CM Documents;1988/H:40, Working paper, 1988)An acoustic survey in the North Sea, Skagerrak and Kattegat was carried out in July-August 1987 by vessels from Denmark and Norway. This paper gives the distribution and the abundance estimates for mackerel. -
LENKA - A nation-wide analysis of the suitability of the Norwegian coast and watercourses for aquaculture. A coastal zone management program
(ICES CM Documents;1988/F:11, Working paper, 1988)A coastal zone management program called LENKA was started in 1987 and is to be terminated in 1989. The aim is to make an efficient and standardized tool for coastal zone planning, which, pertaining to law, is the ... -
