Similar results were reported in Engraulis ringens (Cisneros, 2007), Sardinops melanostictus (Murayama et al., 1994), Salvelinus leucomaenis
(Kagawa et al., 1981), Mugil cephalus (Tamaru et al., 1991), Acheilognathus rhombea (Shimizu et al., 1985), and Oreochromis mossambicus (Cornish, 1998), where oocytes development was mediated by increasing 17[beta]-estradiol during vitellogenesis stage.
Sockeye salmon (Oncorhynchus nerka), brown trout (Salmo trutta) and Japanese trout (Salvelinus leucomaenis
) showed inhibition of digging and swimming behavior against the flow in water slightly acidic (5.8-6.4) compared to neutral pH (6.8-7.1) (IKUTA et al., 2003).
Visiting Russian scientists collected some adult specimens from the hatchery to compare skull morphology with that of the bull trout's close kin, the white-spotted char (Salvelinus leucomaenis
initiated more aggressive acts than S.
Makhnyr and Perlov (1988) reported that spotted seals along the Sakhalin Coast ate pink salmon, Oncorhynchus gorbuscha, found in 83% of the stomachs sampled (n=17), kundzha, Salvelinus leucomaenis
in 33%, redfin, Leuciscus brandti in 33%, Myoxocephalus sp.
