Changes in hemostatic parameters in fish following rapid decompression.

E Casillas, S E Miller, L S Smith

    Undersea Biomedical Research
    |December 1, 1975
    PubMed
    Summary

    Rapid decompression activates the blood coagulation system in coho salmon. This stress response, observed in both mild and severe dives, may lead to consumption coagulopathy in fish.

    Area of Science:

    • Marine Biology
    • Comparative Physiology
    • Fish Physiology

    Background:

    • The hemostatic system is crucial for maintaining blood integrity.
    • Decompression stress in fish can impact physiological processes.
    • Understanding fish blood coagulation is vital for fisheries management and aquaculture.

    Purpose of the Study:

    • To investigate the effects of rapid decompression on the blood coagulation system of coho salmon (Oncorhynchus kisutch).
    • To compare the responses of adult and fingerling salmon to simulated dives.
    • To assess the potential for decompression-induced coagulopathy in fish.

    Main Methods:

    • Simulated dives to 100-fsw and 200-fsw were performed on adult and fingerling coho salmon.
    • Blood samples were collected via dorsal aorta cannula or severed caudal peduncle.
    • Analysis included total plasma protein, fibrinogen concentration, prothrombin time (PT), and partial thromboplastin time (PTT).

    Main Results:

    • Mild decompression (100-fsw) caused fluctuating fibrinogen levels, increased partial thromboplastin times (PTT), and varied prothrombin times (PT) depending on age.
    • Severe decompression (200-fsw) accelerated these hemostatic changes.
    • Both adult and fingerling salmon exhibited activated coagulation systems post-decompression.

    Conclusions:

    • Rapid decompression significantly activates the hemostatic mechanism in coho salmon.
    • The observed changes suggest a potential for consumption coagulopathy in fish, possibly at a higher rate than in mammals.
    • These findings highlight the physiological stress associated with decompression in fish.
