Acid phosphatase activity in pre- and post-spawning hake ( Merluccius Hubbsi)

1. 1. The specific activity of muscle acid phosphatase (B.C. 3.1.3.1.) in pre- and post-spawning hake was investigated. 2. 2. Specific activity values, 0.54 in pre-spawning hakes and 1.64 in post-spawning fish, have been obtained. 3. 3. Using a histochemical test, acid phosphatase has been localized...

Zusammenfassung:	1. 1. The specific activity of muscle acid phosphatase (B.C. 3.1.3.1.) in pre- and post-spawning hake was investigated. 2. 2. Specific activity values, 0.54 in pre-spawning hakes and 1.64 in post-spawning fish, have been obtained. 3. 3. Using a histochemical test, acid phosphatase has been localized mainly in the connective tissue. The strongest reaction has been observed in post-spawning hake. 4. 4. The increase of the lysosomal activity in the connective tissue may be related to the changes found in the muscle texture associated with spawning.
