Electron Microscopy Study of Anterior Neuropituitary of the Sterlet Acipenser ruthenus
Journal of Evolutionary Biochemistry and Physiology, 2003Structural organization of sterlet anterior neuropituitary (ANP), a homologue of the median tubercle of Tetrapoda, was studied by method of electron microscopy. The ANP was conventionally divided in three zones in dorsoventral direction. Neurosecretory fibers (NsF) were concentrated mainly in the central and in the external zones.

This paper provides data concerning biochemical composition of milt of two sturgeon species, Siberian sturgeon bred in aquaculture facility of Inland Fisheries Institute in North Poland and sterlet (from two different populations from Danube and Odra). Milt plasma of Siberian sturgeon and sterlet, when compared to teleost fish, is characterized by much

Crown cells are considered to be typical for the Saccus vasculosus of gnathostome fishes. In Acipenser ruthenus these cells could be found on the entire floor of the diencephalon by SEM. There is one accumulation of crown cells in the frontal Recessus praeopticus, one caudal to the optic chiasma and one on the floor of the Recessus lateralis.

Aminergic nuclear areas were identified in the brain of Acipenser ruthenus using formaldehyde-induced fluorescence (FIF). One group of scattered, green fluorescent cerebrospinal-fluid (CSF)-contacting neurons is located rostral to the commissura anterior.
