“…Assessment of selected peripheral blood haematological parameters and metabolite profiling of liver, muscle and serum samples were performed in 3‐year‐old male and female G. argenteus that had been cultured at 12°C and 16°C. Similar to previous findings by Valdebenito et al (2011) in G. maculatus , erythrocytes, thrombocytes, lymphocytes, monocytes and neutrophils were observed in G. argenteus blood (Lulijwa, Alfaro, Venter, et al, 2021; Lulijwa, Alfaro, Young, et al, 2021).…”

“…Selected haematology and physiological analyses have been conducted with inanga ( Galaxias maculatus ) (Urbina & Glover, 2012; Urbina et al, 2013; Valdebenito et al, 2011), but not G. argenteus . Although G. argenteus is economically important to New Zealand (Wylie et al, 2016), literature on haematology and metabolism remains sparse (Lulijwa, Alfaro, Venter, et al, 2021).…”

This study assessed the selected peripheral blood haematological parameters and metabolite profiles linked to liver, serum and muscle samples in 3‐year‐old male (weight = 131.19 ± 29.24 g; total length = 21.33 ± 1.20 cm; n = 5) and female (122.96 ± 27.04 g; total length = 21.09 ± 1.09 cm; n = 5) giant kokopu (Galaxias argenteus) broodstock cultured at 12°C and 16°C. Temperature and sex did not influence haematocrit values or counts of total blood cells, erythrocytes and leucocytes. However, fish reared at 16°C had higher thrombocyte counts, whereas those kept at 12°C exhibited the highest proportion of lymphocytes. At the metabolic level, sex was the main factor that influenced metabolite levels across tissues, with particularly higher amino acid metabolites in liver of females. Changes linked to the interaction between temperature and sex showed significant differences in fatty acid profiles of liver, and in amino acids in muscle and serum samples. Males kept at 16°C exhibited decreased levels of myristic acid and nonadecanoic acid linked to homeoviscous adaptation. In females, levels for energy metabolites including tyrosine and aspartic acid (in muscle), and alanine (in serum) were disturbed at 16°C. The study provides insights into preliminary haematological and metabolic effects associated with sex and temperature in galaxiids.

“…Nonetheless, observed haematocrit values were within the 20–35% range for wild acclimatized G. maculatus and most teleosts (Clark et al ., 1979; Urbina & Glover, 2012). Erythrocyte, thrombocytes, lymphocytes, monocytes and unquantifiable neutrophils were observed in this species as was reported in G. maculatus (Valdebenito et al ., 2011). Nonetheless, there were effects of age on the erythrocyte profile, age and sex on thrombocyte counts, whereas lymphocytes were only influenced by age.…”

“…This can be partly obtained via haemato‐biochemical profiling (Etim et al ., 2014; Sayed et al ., 2020). Selected cellular parameters of postlarvae and adult common jollytail or inanga ( Galaxias maculatus ) and targeted physiological assessments following stress challenges have been characterized (Urbina et al ., 2013; Urbina & Glover, 2012; Valdebenito et al ., 2011). Nonetheless, data on G. argenteus haematology and metabolomics remain limited.…”

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 age-specific cellular regulation. Higher thrombocyte counts in female fish suggest sex-specific regulation. At a metabolic level, liver abundance for long chain saturated fatty acids (FAs) was higher in males, whereas females had elevated levels of polyunsaturated FAs. Essential and non-essential amino acids (AAs) in liver and serum were also elevated in females compared to males. These findings suggest differential allocation of FAs and AAs to reflect requirements for gonadal, development and provisioning. Similarly, age significantly resulted in higher liver and serum abundances of some non-essential AAs in 3-year-olds compared to 5-year-old fish, suggesting higher metabolism in younger fish. Overall, results enhance our understanding of sex-and age-based differences in fish haematology, muscle, liver, and serum metabolite profiles in healthy G. argenteus. Future studies should carefully consider potential age-and sex-specific differences in metabolic responses.
