INTRODUCTION

The problem.—The improper handling of bañgos fry while in storage prior to stocking them in ponds has often resulted in tremendous mortality, due to overcrowding, unsuitable media used, and possibly other undetermined factors. Present prac¬tices of handling bañgos fry can be further improved through the study of these causative factors, especially in storage.

During recent years the bañgos fry catch has been fluctuat¬ing erratically so that sometimes severe shortages of fry sup¬ply have occurred, to the detriment of the bañgos fishpond industry. With the rapid increase in acreage of fishponds being developed throughout the Philippines coupled with the increasing application of improved technique in fishpond culture and man¬agement, there will be a consequent increase in demand for bañgos fry for stocking purposes. While opening of new fry fishing grounds might be necessary to cope with the ever-in¬creasing demand of bangos fry for stocking, the proper handling of bañgos fry catch from fry grounds would be a proper step in the maximum utilization and conservation of the bañgos fry fishery.
