Ovipleistophora gen. n., a new genus for Pleistophora mirandellae-like microsporidia
(Journal article; Peer reviewed, 2002-03-11)Based on ultrastructural study and molecular analysis, a new genus, Ovipleistophora, is established for Pleistophora mirandellae-like microsporidia from roach and ruff oocytes, Unlike Pleistophora, Ovipleistophora has a ... -
Differential processing of yolk proteins during oocyte hydration in marine fishes (Labridae) that spawn benthic and pelagic eggs
(Journal article; Peer reviewed, 2002-07-18)The yolk proteins and free amino acids (FAA) were investigated during oocyte maturation in 4 species of Labridae with either benthic or pelagic eggs. Benthic eggs and oocytes of both types had a small FAA pool dominated ... -

Overvåking av forurensningsituasjonen i indre Oslofjord 2001 [Fagrådsrapport nr. 88]
(NIVA-rapport;OR-4584, Research report, 2002-10-16)Rapporten omhandler resultatene fra undersøkelser foretatt i Oslofjorden i år 2001. Dypvannsfornyelsen var meget god den kalde vinteren 2001 og dette fikk positive følger for fjordens oksygenforhold og dyreliv. Det ble ... -
Fuel and metabolic scaling during the early life stages of Atlantic cod Gadus morhua
(Journal article; Peer reviewed, 2002-11-13)The simultaneous effect of temperature (5, 7, 10 and 13degreesC) and light on the rates of oxygen consumption and ammonia excretion of larval and early juvenile Atlantic cod Gadus morhua was examined. Larvae increased their ... -

Harvesting Strategies in a Fish Stock Dominated by Low-frequency Variability: The Norwegian Spring-spawning Herring (Clupea harengus)
(Journal article; Peer reviewed, 2003)Heavy positively autocorrelated natural fluctuations in a fisheries stock level are problematic for fisheries management, and collapses in the stock dynamics are difficult to avoid. In this paper, we compare three different ... -
Catchability and the spatial distribution of fishing vessels
(Journal article; Peer reviewed, 2003)A central problem when using commercial catch per unit effort (CPUE) as an index of fish stock abundance is that fishing vessels search for concentrations of fish. For a given stock abundance, CPUE may become high if ... -

Depth-dependent target strengths of gadoids by the boundary-element method
(Journal article; Peer reviewed, 2003)The depth dependence of fish target strength has mostly eluded experimental investigation because of the need to distinguish it from depth-dependent behavioral effects, which may change the orientation distribution. The ... -
A two-dimensional geostatistic method to simulate the precision of abundance estimates
(Journal article; Peer reviewed, 2003)In this paper, we outline a geostatistic method to simulate the relative precision (coefficient of variation, CV) of total abundance estimates of one species in a predetermined, stratified area when it is appropriate to ... -

Using mixed models to combine smooth size-selection and catch-comparison curves over hauls
(Journal article; Peer reviewed, 2003)Parametric size-selection curves are often combined over hauls to estimate a mean selection curve using a mixed model in which between-haul variation in selection is treated as a random effect. This paper shows how ... -
Characterization of strains of Vibrio splendidus and V. tapetis isolated from corkwing wrasse Symphodus melops suffering vibriosis
(Journal article; Peer reviewed, 2003-01-22)Two vibrio bacteria pathogenic to the corkwing wrasse Symphodus melops were isolated. Vibriosis-inducing strain LP1 was isolated as the dominanting bacterium in kidney samples of dead and moribund wrasse from a population ... -
Dose and dose-rate dependency in the mortality response of Calanus finmarchicus embryos exposed to ultraviolet radiation
(Journal article; Peer reviewed, 2003-02-04)In previous work, we reported that embryos of Calanus finmarchicus exposed to artificial ultraviolet-B (UV-B) radiation exhibited high wavelength-dependent mortality. The strongest effects occurred under exposures to ...
