Effects of Artificial Shelter and Chitosan on Growth Performance of Freshwater Prawn (Macrobrachium lanchesteri de Man, 1911).
Two experiments were carried out at the Department of Fisheries, Khon Kaen University, Khon Kaen, Thailand during September 2013 to February 2014 aiming to pursue both the better growth performance and survival rate of the freshwater prawns (Macrobrachium lanchesteri) where a Completely Randomized Design (CRD) with three replications was used for each experiment. For experiment 1, different percentages of grass shelter were used, i.e. 0% (Control, T1), 25% (T2), 50% (T3) and 75% (T4). For experiment 2, different percentages of commercial chitosan were used, i.e. 0% (Control, T1), 25% (T2), 50% (T3) and 75% (T4). Both experiments were carried out at the same time and each of them was lasted for 75 days. The results showed that the added grass shelter gave significantly higher Total Weight (TW) and Survival Rate (SR) than the control treatment. However, there were no significant differences found on TW and SR among the added grass shelter treatments (T2 up to T4). Chitosan gave significantly higher TW, AW and Number of Molting (NM) than the control treatment. There were no significant differences on TW, NM and AW found amongst the chitosan treatments. The results of the experiment 1 showed that the best rate of grass shelter for the culturing of the Macrobrachium lanchesteri was at a rate of 25% (T 2) and the best rate of the chitosan was at a rate of 4% (Diet 3) for the Experiment 2.
