Sampling fish larvae with large pumps; quantitative and qualitative comparisons with traditional gear. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
(Flødevigen rapportserie, Conference object, 1984)Different types of submersible pump systems, ranging in capacity from 3 to 60 m^3/min, have been tested during the period 1977-83 to collect fish eggs and larvae from discrete depths in the Lofoten area. Comparisons ... -
Sampling gear selectivity and its effect on estimates of mean length at age
(PINRO-IMR Symposium, Conference object, 1997)Using data fiom the Norwegian bottorn trawl surveys in the Barents Sea in February ( 1989- 1996), the International O-group surveys in the Barents Sea (1 985-1 996) and previously estimaied selectivity for the standard ... -

Sampling herring in the Norwegian Sea by pelagic trawl
(ICES CM Documents;1997/W:21, Working paper, 1997)When the stock of Norwegian spring-spawning herring is distributed in the Norwegian Sea in summertime, pelagic trawl sampling may be rather challenging because of substantial variation in vertical distribution (from ... -
Sampling of Atlantic salmon using the Norwegian Quality cut (NQC) vs. Whole fillet; differences in contaminant and nutrient contents
(Peer reviewed; Journal article, 2023)Risk- benefit assessments of seafood require high-quality food composition data. In accordance with EU regulations, Atlantic salmon (Salmo salar) has conventionally been sampled using the Norwegian Quality Cut (NQC), a ... -

Sampling planktonic salmon lice in Norwegian fjords
(Journal article; Peer reviewed, 2019)Risk of mortality of wild salmon caused by salmon lice is used as an index for managing aquaculture production in Norway and is based on monitoring of lice attached to wild salmonids and modelled concentrations of lice ... -
Sampling protocol for the determination of nutrients and contaminants in fish and other seafood – The EAF-Nansen Programme
(Peer reviewed; Journal article, 2020)Seafood plays a central role in global food and nutrition security. However, there is a lack of data on the concentration of nutrients and contaminants in fish and other seafood, especially in low- and middle-income ... -
The sampling volume of trawl and acoustics: estimating availability probabilities from observations of tracked individual fish
(Journal article; Peer reviewed, 2009-03-10)The effective sampling volume of trawl and acoustics is an important parameter in fish abundance estimation surveys. This paper presents a method to compute the probability of a fish being available to the bottom trawl and ... -
Sandbanks, sandwaves and megaripples on Spitsbergenbanken, Barents Sea
(Journal article; Peer reviewed, 2019)Recently acquired multibeam echosounder data from the shallowest part (26–53 m depth) of Spitsbergenbanken in the western Barents Sea reveal a variety of bedforms, including megaripples, sandwaves and sandbanks. The bedforms ... -
Sarcotretes scopeli, a lernaeid copepod new to Norway
(Journal article; Peer reviewed, 1971-09-10)Sarcotretes scopeli, parasitic on Benthosema glaciale, is recorded for the first time in Norway. 3.6% of the catch from the Bergen area and 1.9% from Sognefjorden was infested. The parasite seems to retard the growth and ... -

Sårbare fiskeressurser i Skagerrak
(Rapport fra Forskningsstasjonen Flødevigen;1993 nr 1, Working paper, 1993-04-23)This report describes distribution of economically important fish and shellfish and their eggs and larvae in Skagerrak and gives a short discussion on possible exposure to negative man made environmental conditions. -
Scale Character and Growth Rate - A study on small fat herring from North Norway
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1959)From the mean values it can be seen that herring of the "Southern-type" in both years have the same growth rate as those of the "Northern-type". The conclusion must be, therefore, that the correlation, "N-type" - slow ... -
