Abstract

<abstract abstract-type="main" xml:lang="en" id="are12158-abs-0001"> <title>Abstract</title> <p>The suitability of inland saline water (ISW) from the Lahli‐Baniyani Fish Farm, Rohtak was investigated for the larval rearing of giant freshwater prawn (GFP), <italic>Macrobrachium rosenbergii</italic>. Six experiments were conducted. In Experiment‐I, 54% of the larvae metamorphosed to postlarvae (PL) in constituted seawater (CSW) whereas total mortality occurred at larval stages (LS)‐II and LS‐III in ISW with salinity of 12 g L<sup>−1</sup>. Larvae survived to LS‐IV in Experiment‐II, when ISW was supplemented with K<sup>+</sup>~ SW. In Experiment‐III, total hardness in ISW was reduced serially, but K<sup>+</sup> ~ SW was supplemented. The larvae did not survive beyond LS‐V. In Experiment‐IV, ISW was amended with different ratios of Mg<sup>2+</sup>/Ca<sup>2+</sup> and K<sup>+</sup> ~ SW. The larvae successfully metamorphosed to postlarvae with highest survival of 51.6% in Mg<sup>2+</sup>/Ca<sup>2+</sup> ratio of 2.5. In Experiment‐V, eight larval cycles were run with water quality used in Experiment V, where all the cycles produced PL's with a survival rate of 20–67%. In Experiment VI, the larvae were reared in Mg<sup>2+</sup>/Ca<sup>2+</sup> ratio of 2.5 and different levels of K<sup>+</sup> to optimize its requirement. The ISW amended with K<sup>+</sup> 80% ~ SW and Mg<sup>2+</sup>/Ca<sup>2+</sup> ratio of 2.5 was found to be commercially suitable for the seed production of GFP.</p> </abstract>
