Abstract The impacts of wild capture fishing on animal welfare are poorly understood. During purse seine fishing for Atlantic mackerel (Scomber scrombrus), catches are crowded to high densities to facilitate pumping onboard. This study aimed to monit

Stress to fish during harvest in wild capture fisheries is known to negatively influence subsequent survival in catches that are released. Therefore, if fisheries are to be conducted sustainably, there is a need to promote good fish welfare during th

The release of unwanted fish from purse seines whilst still in the water is termed slipping and may lead to significant mortality following release. The objective of this study was to determine the fish welfare implications of a new slipping methodol

The collection of biological data has always been an important part of scientific work in fisheries research. In most cases, records have been written down on a piece of paper and then typed into a computer, but electronic devices that automate lengt

Fourteen herring schools off northern Norway were tracked for about 1 hour each by the 95 kHz Simrad SA950 sonar onboard R/V “G.O. Sars” in May 1994. The sonar was connected to a work station that contained software for reading the echo telegrams

Fourteen herring schools swimming and actively feeding in 15-40 m depth in the Norwegian Sea were followed for about 1 h each in May 1994 using SIMRAD SA950 sidescan sonar: most of the schools were not recorded by a conventional echo-sounder because

Two new sound-recording systems were developed as part of a study on the effects of sound from seismic air guns on fish behavior. The systems were used to record sound pressure levels (SPLs) at several depths and distances from the seismic vessel dur
