Initial salinity tolerance and ion-osmotic parameters in juvenile Russian Sturgeon, Acipenser gueldenstaedtii, Brandt, 1833
The salinity tolerance, hematological and hydromineral regulation capabilities of juvenile Russian sturgeon (Acipenser gueldenstaedtii) were investigated in different ages and sizes in freshwater (FW: 0.05) but differed in experimental media (p < 0.05). Signifi cant differences were observed between the levels of plasma ion concentrations in different media (p < 0.01). Plasma Na+, K+ and Ca+2...
متن کاملFormation and structure of egg envelopes in Russian sturgeon Acipenser gueldenstaedtii (Acipenseriformes: Acipenseridae).
The covering of the eggs in Russian sturgeon Acipenser gueldenstaedtii consists of three envelopes (the vitelline envelope, chorion and extrachorion) and is equipped with multiple micropyles. The most proximal to the oocyte is the vitelline envelope that consists of four layers of filamentous and trabecular material. The structural components of this envelope are synthesized by the oocyte (prim...
متن کاملInitial salinity tolerance and ion-osmotic parameters in juvenile Russian Sturgeon, Acipenser gueldenstaedtii, Brandt, 1833
The salinity tolerance, hematological and hydromineral regulation capabilities of juvenile Russian sturgeon (Acipenser gueldenstaedtii) were investigated in different ages and sizes in freshwater (FW: <0.5‰), estuary water (EW: 9.5‰) and Caspian Sea water (CSW: 12.5‰). The fish were directly transferred from FW to EW and CSW. The possible repercussions of ion-osmoregulatory processes on some ...
متن کاملAnatomical, hormonal and histological descriptions of captive Russian sturgeon (Acipenser gueldenstaedtii) with intersex gonads.
Sturgeons are known throughout the world as the source of black caviar. Their declining populations in their native habitats, mainly the Caspian Sea, due to over-fishing for meat and caviar production, destruction of their spawning grounds and water pollution, have led to their introduction into aquaculture in areas with suitable conditions, including Israel. Recently, we noticed an unusual phe...
متن کاملTranscription of Insulin-like Growth Factor Receptor in Russian Sturgeon (Acipenser gueldenstaedtii) Ovary during Oogenesis
In the present study, we examined the insulin-like growth factor receptor 1(IGF-1R) transcription using real-time PCR at different stages of oocytes of Russian sturgeon (Acipenser gueldenstaedtii) at age 8-9 years and weight 25 kg that were grown under aquaculture conditions. Compare to the pre-vitellogenesis stage, the transcription of IGF-1R increased at the vitellogenesis stages (yellow, gra...
