The solubility of protein components in salmon (Oncorhynchus keta) and sturgeon (Acipenser transmontanus) caviar in distilled water, 5% (w/v) NaCl, 70% (v/v) ethanol at 65C, and 0.2% (w/v) NaOH was determined. The salt soluble proteins were the predominant fraction and constituted 84.2% of the recovered protein in salmon and 86.1% in sturgeon samples. The two most prominent protein fractions (1...

The Sox9 gene of Acipenser sturio, one of the most primitive vertebrates, was analyzed. No sex-specific differences were observed. Sturgeon Sox9 consists of three exons and two introns with completely conserved exon-intron boundaries showing high levels of homology to other vertebrate Sox9 sequences, especially in the N-terminus region containing the HMG box. We found strong evidence for negati...

Abstract Little is known about the distribution and ecology of juvenile green sturgeon throughout their range specifically within California’s Central Valley San Francisco Bay Estuary. The objective our study was to identify rearing movement patterns interaction with Delta habitats. Acoustic biotelemetry used record movements residence different regions this highly modified watershed. We docume...

Ribosomal DNA in sturgeon is informative when analyzed at the molecular level because it bears unique characteristics that are, to a certain extent, ancestral within vertebrates. In this paper, we examine the structure and the molecular evolution of the 5S ribosomal DNA (rDNA) region in 13 sturgeon species, comparing both the 5S ribosomal RNA (rRNA) genes and the non-transcribed spacer (NTS) se...
