Monitoring fish communities at drifting FADs: an autonomous system for data collection in an ecosystems approach
(ICES CM documents;2009, Theme session I, Working paper, 2009)An increasing proportion of landings by tuna purse seine fishing vessels are taken around drifting Fish Aggregating Devices (FADs). Although these FADs and their use by the fishing industry to capture tropical tuna have ... -
Monitoring the Norwegian Coastal Zone Environment (MONCOZE)
(ICES CM Documents;2002/W:3, Working paper, 2002)Introduction: The Norwegian marine coastal environment is characterized by the interaction of complex and coupled physical and biochemical upper-ocean and atmospheric boundary layer processes at spatial and temporal scales ... -
More on the frequency dependence of target strength of mature herring
(ICES CM Documents;1993/B:30, Working paper, 1993)The hibernating stock of Norwegian spring-spawning herring has been acoustically surveyed in a fjord system in northern Norway in December 1992. The survey frequencies are 18, 38, 120, and 200 kHz. When the corresponding ... -
Morphological development of halibut (Hippoglossus hippoglossus) larvae with special reference to mouth development and metamorphosis
(ICES CM Documents;1987/F:18, Working paper, 1987)Halibut (Hippoglossus hippoglossus) larvae were raised from hatching to beyond metamorphosis in 11.5 m3 plastic bags with a temperature stable around 6°C. Standard length, myotome height, eye diameter and yolk sac length ... -
Mortality and injuries of haddock (Melanogrammus aeglefinus) that are caught by pelagic longline
(ICES CM documents, Working paper, 2002)By-catches of haddock (Melanogrammus aeglefinus) below legal size (44 cm total length) in the seasonal pelagic longline fisheries for haddock off the coast of Finnmark, northern Norway, are often high. The small fish are ... -
Mortality and injuries of haddock, cod and saithe escaping through codend meshes and sorting grids
(ICES CM documents, Working paper, 2002)Mortalities and injuries of the gadoids haddock (Melanogrammus aeglefinus L.), cod (Gadus morhua L.) and saithe (Pollachius virens L.) were studied after codend and grid escapement in two full scale trials in 2000 and 2001 ... -
Mortality of herring during the larval stage

Mortality of North Sea herring that is crowded and subsequently slipped from a purse seine
(ICES CM documents;2009/M:16, Working paper, 2009)Catch regulation by slipping whole or parts of the catch has traditionally been used in NE-Atlantic purse seine fisheries for pelagic species if the catches are considered too big or the quality or size of the fish is ... -
Mortality schedules in the early life history phases of juvenile flatfish: European plaice (Pleuronectes platessa) as a case study
(ICES CM documents;2009/T:10, Working paper, 2009)The estimation of natural mortality in early life history stages of fish is difficult because the appropriate data are scarce. Many flatfish, and in particular, plaice (Pleuronectes platessa) have been extensively studied ... -
Multispecies considerations
(Working paper, 1997) -
Mutual impact of wild and cultured Atlantic salmon in Norway
(ICES CM Documents;1988/Mini:5, Working paper, 1988)The development and current status of the fish farming industry, enhancernent and sea ranching of salmon in Norway are briefly described, and an account is given of the natural salmon river populations in different parts ... -

Natural and cultivated zooplankton as food for halibut (Hippoglossus hippoglossus) larvae
(ICES CM Documents;1987/F:17, Working paper, 1987)Natural zooplankton were pumped into a collector and size-fractionated. The zooplankton smaller than 350 ym were fed on a diatom dominated algal suspension cultured in 3 m deep out-door plastic bags. Halibut larvae ... -
Natural fish behaviour and catchability of groundfish
(ICES CM Documents;1994/G:14, Working paper, 1994)Imprecision in estimates of abundance and population parameters obtained from trawl surveys could be reduced if the sources of variability were understood and properly described. Fish behaviour in relation to sampling ... -
NEA saithe XSA runs with different survey tuning series
(Working paper, 2010-02)New tuning series from a combined and improved survey gives lower and more stable S. E. Log q residuals than the tuning series presently used. However, the retrospective trend is still poor and the estimates of F and SSB ... -
Near-bottom sampling with bottom and pelagic trawls
(ICES CM Documents;1987/B:15, Working paper, 1987)The Institute of Marine Research, Bergen, has carried out combined bottom trawl and acoustic surveys for cod and haddock in the Barents Sea - Svalbard area since 1981. These investigations have demonstrated clearly that ...
