      Notes on the construction of 12 cu m ferrocement tank for prawn broodstock 

      RT Tolosa - Journal of Ferrocement, 1978 - International Ferrocement Information Center
      One of the important research studies at the Aquaculture Department of SEAFDEC is the maturation of Penaeus monodon females in captivity. Equal numbers of male and female prawns are stocked in tanks. Ovarian maturation is induced using the eyestalk ablation method.

      Initial successes in obtaining gravid female prawns by ablation in wooden and concrete tanks led to the attempt at mass production of spawners. This significant in view of the high cost of procuring prawn spawners from the wild and of their seasonal spawning.

      This paper is an offshoot of such an attempt. Its aim is to develop an economical, rational and easy method of constructing ferrocement tanks suitable for Penaeus monodon maturation.
