Autor: Davidsen, JG, Knudsen, R, Power, M, Sjursen, AD, Rønning, L, Hårsaker, K, Næsje, TF, Arnekleiv, JV
Publikováno v: Aquatic Biology, Vol 26, Pp 217-227 (2017)
From 2011 to 2013, anadromous brown trout Salmo trutta (213-730 mm, total body length, LT) were collected during or shortly after their marine feeding migration at 7 different localities in central Norway. The mean volume of stomach content (%) of ma

Fouling of externally attached radio transmitters in an African river
Autor: Clinton J. Hay, Weyl Olf, Jacobs Fj, Naesje Tf, Ulvan Em
Fouling of externally attached tags is an important consideration in long term tagging studies as it may affect fish behaviour and well-being. Two externally attached radio transmitters on African tigerfish Hydrocynus vittatus were covered with short

Estuarine and coastal connectivity of an estuarine-dependent fishery species, Pomadasys commersonnii (Haemulidae)
Autor: Dames, MH, Cowley, PD, Childs, A-R, Bennett, RH, Thorstad, EB, Næsje, TF
Publikováno v: African Journal of Marine Science; Vol 39, No 1 (2017); 111-120
Understanding the level of connectivity between estuarine and coastal waters is essential for appropriate management of estuarine-associated taxa. Most studies have focused on the role of a single estuary, while limited research exists on the importa

Influence of prey abundance and abiotic factors on the long-term home-range and movement dynamics of spotted grunter Pomadasys commersonnii in an intermittently open estuary
Autor: Maree, BA, Cowley, PD, Næsje, TF, Childs, A-R, Terörde, AI, Thorstad, EB
Publikováno v: African Journal of Marine Science; Vol 38, No 2 (2016); 171-180
Long-term home-range and movement dynamics of spotted grunter Pomadasys commersonnii and the distribution of their dominant prey, the sandprawn Callichirus kraussi, were investigated in the intermittently open East Kleinemonde Estuary, South Africa.

Life-history parameters of white stumpnose Rhabdosargus globiceps (Pisces: Sparidae) in Saldanha Bay, South Africa, with evidence of stock separation
Autor: Attwood, CG, Næsje, TF, Fairhurst, L, Kerwath, SE
Publikováno v: African Journal of Marine Science; Vol 32, No 1 (2010); 23-35
White stumpnose Rhabdosargus globiceps were sampled over 24 months in Saldanha Bay on the west coast of South Africa. The species is a rudimentary hermaphrodite, with < 1% of mature fish having simultaneously developed ovaries and testes. Spawning ac
