Pavlov, V. Kostin, I. Nechaev, V. Yankovskaya, N. Shindavina, V. Nikandrov, E. Moiseeva, Ya. Kondratenko] In three phenotypic forms (parrs, trout form, and kumzha form) of fish-farm Black Sea trout (age 1+) and wild Black Sea trout (age 1+ and 2+), Salmo trutta labrax, inhabiting the basin of the Mzymta River, the content of monoamines (dopamine, noradrenalin, and serotonin) and of their metabolites (3,4-dihydroxyindolacetic acid, 3-methoxy-4-hydroxyphenyl glycol, and 5-hydroxyindolacetic acid) was investigated in brain regions (forebrain, optic tectum, brainstem, hypothalamus, and hypophysis) and the level of cortisol, thyroxin, triiodothyronine, growth hormone, and adrenocorticotropic hormone was investigated in blood. Data on length and weight of fish body and maturation stage of gonads are indicated. The hormonal level differs in the fish of different phenotypic forms. It is the highest in specimens of the kumzha form which completed parr-smolt transformation. Among wild fish, numerous mature females at age 1+ were found which indicated the presence of a dwarf form of the Black Sea trout in the Caucasus in the Mzymta River.
