Isolation and partial characterization of serum immunoglobuline in two species of sturgeons, Siberian sturgeon (Acipenser baerii) and Stellate sturgeon (Acipenser stellatus)

Marine Science and Technology Bulletin, 2018
The immunoglobulins (Igs) were isolated and purified respectively from serum of Siberian sturgeon (Acipenser baerii) and Stellate sturgeon (Acipenser stellatus) by using 50% saturated ammonium sulfate precipitation. Analysis of the purified Ig of the two

Strengthening community‐based fisheries monitoring programs with Indigenous perspectives

Conservation Biology, EarlyView.
Abstract Community‐based monitoring (CBM) programs are increasingly recognized as essential for adaptive environmental stewardship. Yet, the CBM literature often highlights successful cases and privileges evaluations by external experts over those of community members themselves.

Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

Journal of Fish Biology, EarlyView.
Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...

Longest documented coastal migrations of shortnose sturgeon

Journal of Fish Biology, EarlyView.
Abstract The shortnose sturgeon (SNS; Acipenser brevirostrum) is a United States federally endangered diadromous species. Although SNS spend much of their time in riverine habitat, inter‐river migrations have been documented in northern populations.

Molecular insights into electroreceptor ribbon synapses from differential gene expression in sturgeon lateral line organs

Journal of Anatomy, EarlyView.
The expression of various genes involved in synapse development, stability and/or function was studied in developing mechanosensory neuromasts and electrosensory ampullary organs in sterlet sturgeon. Most were shared, including Slc17a8, Slc1a3 and Nrxn3, but Cbln18 was neuromast‐restricted and Tulp1 was ampullary organ‐restricted.
