Reactions of herring to trawling noise
(ICES CM Documents;1988/B:36, Working paper, 1988)The reaction of herring during pelagic trawl sampling has been studied by use of a high-frequency scanning sonar mounted on the headline of the trawl. The difficulties of obtaining high catch rates on shallow herring ... -
Recent developments on blue whiting trawls in Norway.
(ICES CM Documents;1979/B:24, Working paper, 1979)Two new blue whiting trawls with very large meshes in the front part have been tested with regard to towing resistance, operational qualities and catching efficiency. The results confirm that the large mesh design is quite ... -
Recent experiments with net of hexagonal meshes in purse seines.

Recommendations for the collection of multifrequency acoustic data
(ICES CM Documents;2004/R:36, Working paper, 2004)Traditionally, collection of acoustic data has been optimised for a single frequency, while requirements for the optimal combination of multifrequency data has been given less attention. Even though data manipulation can ... -
Redskapsforskjeller ved fiske etter nordøstarktisk torsk (skrei) under gytesesongen i Lofoten med spesiell fokus på snurrevad – basert på Havforskningsinstituttets database for årene 1946–2009
(Rapport fra Havforskningen;Nr. 29-2013, Working paper, 2013) -
Reduced bycatch of red king crab (Paralithodes camtschatica) in the cod gillnet fisheries in northern Norway: Fishing trials with norsel mounted gillnets
(ICES CM documents, Working paper, 2000)Bycatch of red king crab (Paralithodes camtschatica) in stationary fishing gears, q&ally gillnets, is an increasing problem to the inshore fishermen in the northern part of Norway (Finnmark county). The results are large ... -
Reduction of fish bycatch in shrimp trawl using a solid separator grid in the aft belly
(ICES CM documents;1990/B:47, Working paper, 1990)During 1989-90 a new concept to avoid bycatch of fish in shrimp trawl has been developed in Norway. The system consists of an aluminium grid, 0.6 - 1.0 m wide and 1.3 - l.5 m long, with bars spaced 19 mm. The grid is ... -
Reketrål med kort belg reduserer fangst av undermålsreker

Relation of maximum and average target strengths for the same fish
(ICES CM documents, Working paper, 1987)The relation is studied by means of tabulated measurements of the tilt angle dependence of target strength for three gadoid species. The dependence of the difference target strength on fish length is statistically ... -
Relationship between survey indices of recruitment and VPA abundance estimates for North-East Arctic cod
(PINRO-IMR Symposium, Conference object, 1995)Survey estimates of abundance of recruiting and partially recruited age groups are important elements for tuning the VPA of north-east Arctic cod, both for estimating the present state of the stock and for future ... -
Relationships between the geometric dimensions and biomass of schools
(ICES CM Documents;1990/B:41, Working paper, 1990)Acoustic measurements of the geometric dimensions and packing density of herring, sprat and saithe schools have been conducted by multi-beam sonars and echo integrator systems. Relationships between the reflected echo ... -
The relative frequency response, as derived from individually separated targets on cod, saithe and Norway pout
(ICES CM documents, Working paper, 2004)The relative frequency response is an important acoustic feature used to characterise acoustic targets. This response has been defined as the sv, volume backscattering coefficient, for a specific frequency relative to ... -
Relative selectivity in trawls, longline and gillnets on Greenland halibut
(PINRO-IMR Symposium, Conference object, 1997)Selectivity parameters for Greenland halibut (Reinhardtius hippoglossoides, Walbaum) are compared to catches reported fiom trawl, gillnets and longline in the Norwegian scientific fisheries for Greenland halibut. A trouser ... -
