title: Effect of maturation on activities of various proteases and protease inhibitors in the muscle of Ayu (Plecoglossus altivelis).
abstract: 1. Increases in activities of muscle muticatalytic proteinase, modori-inducing proteinase (latent trypsin-like proteinase), cathepsin B and L-like proteases and cathepsin D were observed more markedly for male fish than female fish, in the spawning stage. 2. Decreases in inhibitory activities of muscle serine and cysteine protease inhibitors were observed more markedly for male fish than female fish in the spawning stage.
