Long-term changes in the total egg production of Norwegian spring-spawning herring Clupea harengus (L.)—Implications of variations in population structure and condition factor
(Journal article; Peer reviewed, 2010-05)The reproductive potential of Norwegian spring-spawning herring (Clupea harengus) was estimated in terms of total egg production (TEP) for the period 1935–2005, using a model where spawning stock numbers (SSN)-, weight- ... -
The fate of vitellogenic follicles in experimentally monitored Atlantic cod Gadus morhua (L.): Application to stock assessment
(Journal article; Peer reviewed, 2010-05)In this paper we report on the fate of vitellogenic follicles (VF) as either alpha atretic follicles (αF) or post-ovulatory follicles (POFs) using histology and captive Atlantic cod (Gadus morhua) in three experiments. In ... -
Stereological calibration of the profile method to quickly estimate atresia levels in fish
(Journal article; Peer reviewed, 2010-05)The (physical) ‘disector method’, a frequently cited stereological technique, has so far received little attention within fish fecundity studies, although it can be used to provide unbiased, assumption-free data on levels ... -
Mechanisms regulating oocyte recruitment and skippedspawning in Northeast Arctic cod (Gadus morhua L.)
(Journal article; Peer reviewed, 2009-09)To examine mechanisms that affect fecundity, atresia and skipped spawning in Northeast Arctic cod (Gadus morhua L.), we conducted an experiment where wild-caught cod (>60 cm) kept under restricted food regimes were subjected ... -

Forensic identification of severely degraded Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss) tissues
(Journal article; Peer reviewed, 2010-11-03)Aquaculture is a globally important and rapidly growing industry. It contributes positively to the economy and sustainability of coastal communities, but it is not without regulatory challenges. These challenges are diverse, ... -
Exploration and learning of demand-feeding in Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2010-08-15)A bite–and–pull demand–feeding system was introduced to groups of cultured cod (Gadus morhua). For half of the groups trigger actuations were rewarded with food, while actuations were unrewarded in the other groups. ... -
Mortality of mackerel (Scomber scombrus L.) after pursing and slipping from a purse seine
(Journal article; Peer reviewed, 2010-10)A new method was used to study the effect of crowding and subsequent slipping from a purse seine on the mortality of Atlantic mackerel (Scomber scombrus L.). Mackerel were allowed to swim from a purse seine through a ...
