| organohalogens and metals in marine fish and mussels and some relationships to biological variables at reference localities in norway. | the main goals of this study were to define, for the norwegian coast, "high background" levels of micropollutants routinely monitored within the the oslo and paris commission joint assessment and monitoring programme, and to reassess the present norwegian reference levels used as the basis for a classification of environmental quality. the indicator organisms analysed as bulked/individual samples were cod (gadus morhua, n approximately 1170; n approximately 240 for organochlorines), dab (limanda ... | 2003 | 12604072 |
| characterization of atlantic cod spawning habitat and behavior in icelandic coastal waters. | the physical habitat used during spawning may potentially be an important factor affecting reproductive output of broadcast spawning marine fishes, particularly for species with complex, substrate-oriented mating systems and behaviors, such as atlantic cod gadus morhua. we characterized the habitat use and behavior of spawning atlantic cod at two locations off the coast of southwestern iceland during a 2-d research cruise (15-16 april 2009). we simultaneously operated two different active hydroa ... | 2012 | 23236471 |
| inferring fish escape behaviour in trawls based on catch comparison data: model development and evaluation based on data from skagerrak, denmark. | during the fishing process, fish react to a trawl with a series of behaviours that often are species and size specific. thus, a thorough understanding of fish behaviour in relation to fishing gear and a scientific understanding of the ability of different gear designs to utilize or stimulate various behavioural patterns during the catching process are essential for developing more efficient, selective, and environmentally friendly trawls. although many behavioural studies using optical and acous ... | 2014 | 24586403 |
