Changes with time of ammonia and urea concentrations in the blood and tissue of mudskipper fish, Periophthalmus cantonensis and Boleophthalmus pectinirostris kept in water and on land

Postprandial increases in nitrogenous excretion and urea synthesis in the giant mudskipperPeriophthalmodon schlosseri

“…The activities of arginase and urate oxidase in their livers are high enough to account for the rate of urea excretion (Gregory, 1977). Working on the mudskippers Periophthalmus modestus (as P. cantonensis) and Boleophthalmus pectinitrostris, Morii (1979) and Morii et al (1978Morii et al ( , 1979 reported that ammonia was not detoxified to urea in these mudskippers during aerial exposure. Iwata et al (1981) and Iwata (1988) also reported that urea production remained unchanged in P. modestus exposed to environmental ammonia or terrestrial conditions.…”
