The use of rock salt, solarsalt, rock salt brine and stock solution for larval culture of macrobrachium rosenbergil

Abstract

It has been well understood that, in ture, the giant freshwater prawn, Macrobrachium resenbergii De Man, attains maturity in fresh waters but breeds in brackish waters. This unusual requirement of different aquatic habitats in its life cycle confines the prawn’s artificial breeding and rearing activities in the areas close to se waters. As a result, attempts were made at Chachoengsao fisheries Station to eliminate such a limitation, and success was then achieved in 1980 by mixing rock salt, solar salt field. The studied mixtures gave the same satisfactory results on breeding and rearing of the prawn larvae as those brought about by a conventional seawater-freshwater mixture. Informations obtained from this study could also be used as a guiding model aimed at the improvement of breeding and rearing of brackish water or marine species particulary in locations far away from sea waters.
