Abstract

LERPIDO, RQMIMEL R., University of the Philippines at Los Banos, March, 1986. Esterase Isozymes of the Philippine Milkfish, Chanos chanos (Forskal) (Class Osteichthyes, Family Chanidae) Raised in two Different Environments. Major Adviser: Mr. Ivan-Marcelo A. Duka

Sixty milkfish of different sizes and weights, thirty from Los Banos portion of Laguna Lake and thirty from Alabang portion, were individually examined for their cardiac and epaxial muscle esterase • isozymes. A total of seventeen bands were obtained for all the samples examined. Multiple esterase forms of one to five bands per tissue were obtained with reference to electrophoretic mobility. Isozyme 1, the fastest moving band, had an if value of 0.980 while the slowest moving band, isozyme 1 had an Rf value of 0.420. Isozymes 10 and 11, which were found common in all sample sets, were classified to be non-tissue specific esterases. Cardiac muscle esterase of milkfish from the Los Banos area were observed to be less anodal which were significantly different from the more :modal for.as exhibited by the other three tissues, grouped primarily under Zone 1. All bands exhibited varying intensities ranging front very low to very high.
