Allometric growth and development of organs in ballan wrasse (Labrus bergylta Ascanius, 1767) larvae in relation to different live prey diets and growth rates
Kjørsvik, Elin; Gagnat, Maren Ranheim; Bardal, Tora; Wold, Per-Arvid; Øie, Gunvor (Journal article; Peer reviewed, 2016)Small fish larvae grow allometrically, but little is known about how this growth pattern may be affected by different growth rates and early diet quality. The present study investigates how different growth rates, caused ... -

Microbial characterization and influence on copepod (Acartia tonsa) nauplii and egg production in water treatment systems with and without membrane filtration
Phan Hung, Anh (Master thesis, 2014)Acartia tonsa is a pelagic calanoid copepod with a diverse distribution, a wide tolerance of temperature and salinities, has short generation time, can produce resting eggs, and has been considered as an excellent feed for ... -
The digestive system of ballan wrasse (Labrus bergylta), a marine agastric carnivorous teleost
Flaten, Steinar (Master thesis, 2021)The knowledge of the digestive system of teleosts is limited, especially when considering the huge variation in morphology. There are particularly few studies of the digestive system of agastric (stomachless) teleosts such ...
