AbstractSturgeons belong to an ancient group of the extant actinopterygian fishes. Accordingly, the study of their brain connections is important to understand brain evolution in the line leading to teleosts. We examined the topography and connections of the various telencephalic regions of the Siberian sturgeon (Acipenser baeri).

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

In this paper we investigate by means of immunohistochemistry, the tissue distribution of constitutive cytochrome P4501A (CYPIA), from hatching until 30 days posthatching in developing Siberian sturgeon, Acipenser baeri. For this purpose, a polyclonal (BN-1) antiserum developed against a conservative sequence of piscine CYP1A and a monoclonal (C10-7 ...

Genistein (G) is a xenoestrogen from soy present in fish diet. In vivo, a 50-fold difference in sensitivity to genistein on vitellogenin (VTG) synthesis was found when comparing trout and sturgeon. This difference was not linked to the estrogen receptor affinity nor to the sensitivity of induction of the VTG pathway. The study was performed to check if

AbstractGalanin is a 29‐amino acid peptide widely distributed in the central nervous system of vertebrates. The organization of galaninergic systems is well known in teleosts, the most advanced actinopterygians, but no data are available on primitive bony fish.

Alimentation artificielle de l'esturgeon Acipenser baeri
1979Depuis le mois de mai 1976, un lot d'esturgeons sibériens Acipenser baeri a été acclimaté en France, d'une part à la station de l'Inra de Donzacq (Landes), d'autre part à la station expérimentale en eau réchauffée du Ctgref, à la centrale d'Ambès (Gironde).

Acute toxicity of ammonia to Siberian sturgeon Acipenser baeri
1991Median lethal concentrations (LC50) of ammonia were determined for Siberian sturgeon (A.baeri) in static tests. The respective 24 h NH3 LC50 for different weight groups - 60 mg, 10 to 270 g and 450 g - were 1 mg/l, 1,7 mg/l and 2,5 mg/l. Sturgeon are more resistant than rainbow trout (Oncorhynchus mykiss).

Ovarian development and cycles in cultured Siberian sturgeon, Acipenser baeri
1998Les esturgeons ne présentent pas de dimorphisme sexuel et ont des durées de cycles ovariens supérieures à 1 an. En pratiquant des biopsies sur des animaux marqués, nous avons identifié le sexe et suivi le développement ovarien d'une cohorte d'esturgeons sibériens mis 5 ans en élevage, de 8,5 à 12,5 ans. Le sex-ratio dans la population ne diffère pas du
