Automatic recording of fish heart rate on a personal computer
(ICES CM Documents;1988/B:34, Working paper, 1988)From acoustic tags operated into fish in a closed system, the heartbeat signals are sent via underwater telemetry and counted on a personal computer. The computer removes false pulses caused by noise, and calculates the ... -
Automatic species recognition, length measurement and weight determination, using the CatchMeter computer vision system
(ICES CM documents, Working paper, 2006)The collection of biological data on species composition and individual length and weight of specimen has always been an important part of fisheries research. Traditionally, the collected information has been recorded on ... -
The autumn spawning group of herring in the north-eastern North Sea
(ICES CM Documents;1966/H:26, Working paper, 1966) -
Avoidance from petroleum hydrocarbons by the cod (Gadus morhua)
(ICES CM Documents;1982/E:56, Working paper, 1982) -
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 ... -
Avoidance reactions of ultrasonic tagged cod during bottom trawling in shallow water
(ICES CM Documents;1991/B:41, Working paper, 1991)Introduction: Observations made by echo sounder (Ona 1988) have shown that cod (Gadus morhua L.) may avoid an approaching survey vessel horizontally and vertically. However, there has been a lack of information on the ... -
Await in the pelagic: herring compromising reproduction and survival within a vertically split school
(ICES CM documents, Working paper, 1998) -
Back-calculated length at age in Norwegian spring-spawning herring (Clupea harengus L.) : Estimating the common intercept or origin by tuning back-calculated length frequencies to observed ones
(ICES CM Documents;1996/D:9, Working paper, 1996)In Norwegian spring-spawning herring the common intercept of the back-calculating formula, as estimated by linear regression of the fish-scale relationship, grosssly overestimated the back-calculated length frequencie ... -
Bacterial diseases of eggs and yolk sac larvae of halibut (Hippoglossus hippoglossus L.): Characterization and experimental infection
(ICES CM Documents;1990/F:38, Working paper, 1990)Scanning electron micrographs of halibut eggs which were shown to have an epiflora dominated by a Flexibacter sp., revealed wounds colonized by large amounts of bacteria. The chorion was penetrated in most wounds, and ... -
Bad-weather calibration of split-beam echo sounder systems
(ICES CM Documents;1990/B:22, Working paper, 1990)A condition for standard-target calibration is stability of the sonar platform and target rig. This condition cannot always be met, nor need it be when the transducer has a split-beam function. Since the position of ... -
Barents Sea Ecosystem Resilience under global environmental change 2010-2013
(ICES CM Documents;2010/Q:27, Working paper, 2010) -
Barents Sea King Crab (Paralithodes camtschatica). The transplantation experiments were successfull
(ICES CM Documents;1994/K:12, Working paper, 1994)As a result of the USSR tranplantation experiments, a viable, self-reproducing poulation of king crab, (Paralithodes camtschatica), is now well established in the Barents Sea. Commercial fishing for king crab is prohibited ... -
Basic studies of Norwegian longline gear
(ICES CM Documents;1976/B:27, Working paper, 1976) -
Bath-vaccination against vibriosis
(ICES CM Documents;1981/F:47, Working paper, 1981) -
Bathymetric conformal variography of the spawning stock of Northern blue whiting
(ICES CM Documents;1996/S:46, Working paper, 1996)Bathymetric-based conformal isotropic and anisotropic variograms are defined. These are applied to the spawning stock of northern blue whiting (Micromesistius poutassou) along the slope of the continental shelf west of the ... -
Behaviour aspects of fish in relation to oil platforms in the North Sea.
(ICES CM Documents;1979/B:27, Working paper, 1979)Fish distribution around structures of the Ekofisk oil field in the central North Sea was investigated by means of gillnet fishing, longlining, jigging and echosurveying. The studies were carried out during one week in ... -
Behaviour of Atlantic salmon (Salmo salar L.) recorded by data storage tags in the NE Atlantic – implications for interception by pelagic trawls
(ICES CM documents, Working paper, 2006)In a project carried out in the Nordic Seas (Northeast Atlantic) in 2002 - 2004, 413 Atlantic salmon (Salmo salar L.) were tagged with data storage tags (DST) either logging temperature and depth (StarOddi, Milli) or ... -
Behaviour of Atlantic salmon smolts during seaward migration. I: Preliminary report on ultrasonic tracking in a Norwegian fjord system
(ICES CM Documents;1982/M:7, Working paper, 1982) -
Behaviour of Norwegian spring spawning herring in relation to underwater light
(ICES CM Documents;1988/B:24, Working paper, 1988)The Norwegian coastal purse seiners, with shallow nets, have experienced difficulties in catching the herring due to their natura! behaviour being located too deep during day time and toe scattered during night time. ... -
Behaviour of saithe penned in different densities.
(ICES CM Documents;1980/B:26, Working paper, 1980)In Norway purse seine catches of live saithe are towed to the coast and kept in net pens until the fish can be processed by the fishing industry. During penning - especially during "short-time" penning - the quality of ...
