MS Divinagracia shares pantat hatching technique

On November 17, 2010, CPU TGP Team members led by RACG representative Prof. Hope G. Patricio and RMISG representative Engr. Aries Roda D. Romallosa revisited the pantat hatchery of MS Luel Divinagracia in Sitio Bulod II, Brgy. Pulao, Dumangas to document his unique way of hatching pantat through actual demonstration.

It all starts with choosing the ideal gravid pantat that is about to lay the eggs and the male pantat. The pituitary gland of the male pantat is removed, crushed and mixed with sodium chloride solution. The mixture is then injected to both sides of the upper dorsal fin of the gravid pantat. The newly injected females together with other males are placed in a basin with water covered with screen. The basin is then placed in an area where people usually pass by so that the male pantat will thrush around bumping the pregnant pantat. This bumping loosens the eggs making it easier to squirt them out.

This unique way of hatching was developed by MS Divinagracia after observing other hatcheries and by trial and error method when he was just starting in the business. Mr. Divinagracia is the Magsasaka Siyentista of FITS Dumangas. (Hope G. Patricio, RAC Representative, Central Philippine University)
