Changes in hormone profiles in relation to ultrasound-determined testis maturation during a reproductive cycle in Atlantic salmon (Salmo salar)
Hoque, Md. Enamul (Master thesis, 2016)At present, fully mature males are identified by checking for running milt by palpitation during gamete production of Atlantic salmon (Salmo salar). Ultrasound (US) technology could provide a cheap and fast method to monitor ... -
Development of non-invasive methods using ultrasound technology in monitoring of Atlantic salmon (Salmo salar) production and reproduction
Næve, Ingun (Doktoravhandlinger ved NTNU;2020:51, Doctoral thesis, 2020)In production of Atlantic salmon (Salmo salar) broodfish, handlings for lice and disease management, gradings and checks for progression of sexual maturation, are inevitable. These handlings cause stress responses and can ... -
Reproductive biology of lumpfish (Cyclopterus lumpus): a key to successful selective breeding
Puvanendran, Velmurugu; Burgerhout, Erik; Hansen, Øyvind J; Tveiten, Helge; Kjørsvik, Elin; Mlingi, Frank Thomas; Tomkiewic, Jonna; Mommens, Maren; Hageskal, Rikard; Iversen, Nina (Nofima rapportserie;20/2022, Research report, 2022)A detailed description of lumpfish reproductive biology has been described in terms of gonadal development using histological analysis and physiology using sex steroid development. This knowledge of basic reproductive ... -
Reproductive performance of lumpfish (Cyclopterus lumpus, L. 1758) females: Effects of integrated photoperiod and temperature manipulations on sexual maturation and spawning
Mlingi, Frank Thomas; Burgerhout, Erik; Mommens, Maren; Tveiten, Helge; Tomkiewicz, Jonna; Kjørsvik, Elin; Puvanendran, Velmurugu (Journal article; Peer reviewed, 2024)A successful control of sexual maturation is crucial for year-round production of lumpfish juveniles destined as cleaner fish in Atlantic salmon aquaculture. This study investigated the combined effects of photoperiod and ... -
Ultrasonic imaging as a means of monitoring gonadal development in lumpfish (Cyclopterus lumpus)
Mlingi, Frank Thomas; Puvanendran, Velmurugu; Burgerhout, Erik; Tveiten, Helge; Tomkiewicz, Jonna; Kjørsvik, Elin; Mommens, Maren (Peer reviewed; Journal article, 2023)The commercial farming of juvenile lumpfish requires monitoring of gonadal development to achieve synchronized production. Conventional methods such as gonadosomatic index (GSI), sex hormone analyses, gonadal histology, ... -
Ultrasound as a non-invasive tool for monitoring reproductive physiology in female Atlantic salmon (Salmo salar)
Næve, Ingun; Mommens, Maren; Arukwe, Augustine; Kjørsvik, Elin (Journal article; Peer reviewed, 2018)Aiming to explore ultrasound technology as a noninvasive method for maturation monitoring, we compared ultrasound observations and measurements in female Atlantic salmon (Salmo salar) during the last year before ovulation ... -
Ultrasound as a noninvasive tool for monitoring reproductive physiology in male Atlantic salmon (Salmo salar)
Næve, Ingun; Mommens, Maren; Arukwe, Augustine; Virtanen, Jonni; Hoque, Md Enamul; Kjørsvik, Elin (Journal article; Peer reviewed, 2019)We examined the potential for ultrasound as a noninvasive tool for maturation monitoring in Atlantic salmon (Salmo salar) males. Ultrasound examination and measurements were compared to common practices for maturation ...
