This study characterized selected peripheral blood (PB) haematological parameters, liver, serum and muscle metabolic features in 3‐ and 5‐year‐old male and female giant kokopu ( Galaxias argenteus ) broodstock reared indoor at 16°C. Sex and age did not affect PB total cell count and haematocrit values. Nonetheless, higher erythrocytes in 5‐year‐old fish, elevated thrombocyte and lymphocyte counts in 3‐year‐old fish indicate ag...

We sought to determine a compatible anticoagulant for routine haematological and physiological assessments with giant kokopu ( Galaxias argenteus ), an endemic New Zealand fish. We observed that blood treated with lithium heparin (LH) rapidly coagulated and haemolysed, making it unsuitable for G. argenteus . Dipotassium ethylenediaminetetraacetic acid (K 2 EDTA) and trisodium citrate (citrate) effectively prevented blood coagu...

Polyinosinic:polycytidylic acid [poly (I:C)] was administered in vivo to Chinook salmon ( Oncorhynchus tshawytscha ) post‐smolts to determine the immune responses on haematological and cellular functional parameters, including spleen (SP), head kidney (HK) and red blood cell (RBC) cytokine expression, as well as serum metabolomics. Poly (I:C) in vivo (24 h exposure) did not affect fish haematological parameters, leucocyte phag...

Mass mortality events are routinely reported in bivalve cultivation practices worldwide with significant economic consequences for the global aquaculture industry. Major contributors of these bivalve losses are infections caused by viruses and bacteria whose molecular action mechanisms are still not fully understood. This major bottleneck for shellfish cultivation presents an opportunity for fundamental research that can gener...

From the first detection in the Eastern oysters ( Crassostrea virginica ) in 1972, herpes‐like viruses/herpesviruses have been identified in at least 20 bivalve species and have caused massive mortalities in six cultured species of bivalves. Among them, the Pacific oyster ( Crassostrea gigas ) is most threatened by massive mortalities associated with detection of Ostreid herpesvirus 1 (Os HV ‐1) and its variants. These mortali...
