...Li-Yih Lin; Pung-Pung Hwang SUMMARY Mitochondria-rich cells (MRCs) in the yolk-sac membrane of tilapia( Oreochromis mossambicus ) larvae were examined by Na + /K + -ATPase immunocytochemistry and vital staining for glycoproteins following acclimation to high (7.5–7.9 mmol l –1 ), normal (0.48–0.52...

...Kiyono Shiraishi; Junya Hiroi; Toyoji Kaneko; Manabu Matsuda; Tetsuya Hirano; Takao Mori SUMMARY To examine the functional differentiation of chloride cells in the yolk-sac membrane of tilapia ( Oreochromis mossambicus ) embryos, we developed a ‘yolk-ball’ incubation system in which the yolk sac...

...Patrick R. Wells; Alan W. Pinder ABSTRACT During development from larva to juvenile in Atlantic salmon, Salmo salar , there is a change in the anatomical potential for gas exchange among gills, body skin and yolk sac as the larvae resorb yolk, grow and develop gills. Newly hatched Atlantic salmon...

...Patrick R. Wells; Alan W. Pinder ABSTRACT During post-hatch development of Atlantic salmon ( Salmo salar L.), O 2 uptake partitioning changes from primarily cutaneous to primarily branchial. Over 80 % of post-hatch O 2 uptake was cutaneous, with the yolk sac responsible for 33 % of total O 2 uptake...
