“…In rainbow trout, kept at 15" C, Gaudet et al (1975) and Racicot et al (1975) found average LDH activities of 1155 and 861 U 1 respectively. Even data reported from different species of fish are in the same order of magnitude (Grigo, 1975;Marquez, 1976).…”

Activities of lactate dehydrogenase, hydroxy butyric dehydrogenase, glutamic oxalacetic transaminase, glutamic pyruvic transaminase, glutamate dehydrogenasc, creatinine kinase, alkaline phosphatase, and leucine amino peptidase were determined in the sera of rainbow trout. The animals had previously been adapted to temperatures of 3.5, 6, 8, 10, 12.5, 15, 17, 19, 21.5 and 23" C . Most of the enzyme activity increased with the rise in temperature. The activity of alkaline phosphatase decreased in the range 6-19' C , while the changes in the glutamate dehydrogenase activity took a complex course. The results Are compared with the findings of other authors.

“…However, interpretation of results was limited by lack of reference values. In the only published study of normal plasma enzyme values in Pacific herring (Marquez 1976), analysis of electrolytes and other nonenzyme chemistries was not included. Marquez (1976) captured 5 to 12 Pacific herring by angling, held the fish for 12 h, and then drew blood to analyze for plasma enzymes at 30°C.…”

Viral hemorrhagic septicemia virus, Ichthyophonus hoferi, and other causes of morbidity in Pacific herring Clupea pallasi spawning in Prince William Sound, Alaska, USA

et al. 1998

Pacific herring Clupea pallasi populations in Prince William Sound, Alaska, USA, declined from an estimated 9.8 x 10(7) kg in 1992 to 1.5 x 10(7) kg in 1994. To determine the role of disease in population decline, 233 Pacific herring from Prince William Sound were subjected to complete necropsy during April 1994. The North American strain of viral hemorrhagic septicemia virus (VHSV) was isolated from 11 of 233 fish (4.7%). VHSV was significantly related to myocardial mineralization, hepatocellular necrosis, submucosal gastritis, and meningoencephalitis. Ichthyophonus hoferi infected 62 of 212 (29%) fish. I. hoferi infections were associated with severe, disseminated, granulomatous inflammation and with increased levels of plasma creatine phosphokinase (CPK) and aspartate aminotransferase (AST). I. hoferi prevalence in 1994 was more than double that of most previous years (1989 to 1993). Plasma chemistry values significantly greater (p < 0.01) in males than females included albumin, total protein, cholesterol, chloride, glucose, and potassium; only alkaline phosphatase was significantly greater in females. Hypoalbuminemia was relatively common in postspawning females; other risk factors included VHSV and moderate or severe focal skin reddening. Pacific herring had more than 10 species of parasites, but they were not associated with significant lesions. Two of the parasites have not previously been described: a renal intraductal myxosporean (11% prevalence) and an intestinal coccidian (91% prevalence). Transmission electron microscopy of a solitary mesenteric lesion revealed viral particles consistent with lymphocystis virus. No fish had viral erythrocytic necrosis (VEN). Prevalence of external gross lesions and major parasites was not related to fish age, and fish that were year-lings at the time of the 1989 'Exxon Valdez' oil spill (1988 year class) had no evidence of increased disease prevalence.

“…Both the natural and artificial reproduction of fish belong to factors seriously affecting internal milieu of the organism (Marquez 1976;Hlavová 1989;Lusk 1995a, 1995b;Hochachka and Mommsen 1995;Lus ková 1997a;Svoboda et al 2000).…”

The aim of this study was to assess the biochemical profile of tench blood plasma during preand postspawning period under the conditions of hormonally-induced artificial reproduction. A total of 59 females and 27 males were examined during the postspawning period of 1999 and 52 females and 25 males were examined during the prespawning period of 2000, as well as 48 females after reproduction. Biochemical indices determined in blood plasma were as follows: cortisol, glucose, total protein (TP), triacylglycerols (Tcg), cholesterol (Chol), transaminases (ALT and AST), creatine kinase (CK), alkaline phosphatase (ALP) and electrolytes (Na). In females in the pre-spawning period, higher values of TP (P < 0.05) and Tcg (P < 0.01) were found compared to males. Immediately after reproduction, males had higher TP (P < 0.01) and Chol (P < 0.01) than females. No significant sex-related differences were found in other indices under study. Higher values of glucose (P < 0.01), Tcg (P < 0.01), Chol (P < 0.05), AST (P < 0.01) and ALP (P < 0.01) were found for females after reproduction in June compared to values found in April, i.e. two months prior to reproduction. Differing water temperature (10.3 °C in April; 22 °C in June) associated with metabolic rate also played an important role. Induction of ovulation by GnRH synthetic analogue and carp pituitary was not successful in all females. However, between the spawned and unspawned female fish, differences were found in glucose concentration (P < 0.01) but non-significant differences were recorded for other biochemical indices. The blood plasma biochemical profile enabled to assess the state of internal milieu of broodstock during the reproduction period.
