The major interest is focused on the understanding of endocrine mechanisms regulating physiological and behavioural response to environmental change (light, salinity, temperature) in fish. The research is concentrated on the interrelation between pineal melatonin and neurohypophysial hormones arginine vasotocin and isotocin.
Principal methods: HPLC + SPE, RIA, Autoradiography.
