is used to feed fish and crustacean larvae in the aquaculture industry. It is well established that the type of microalgae may influence rotifer production. This experiment was conducted to determine the effect of five different locally available microalgae species at Fisheries Research Institute (FRI), Kampung Pulau Sayak, Kedah, Malaysia on the instantaneous growth rate (μ) of rotifer. sp., sp., sp., sp., and sp. were used as feed at different algae densities (0.1, 0.3, 0.7 and 1.5 × 10 cells/ml) and culture volumes (20, 70 and 210 ml). At algae densities ranging from 0.3 to 1.5 × 10 cells/ml, an average μ value of more than 0.90 per day were recorded for all algae species. However, at density of 0.1 × 10 cells/ml, only sp. resulted in the significantly highest μ value compared with others ( < 0.05). In terms of volume, smaller culture volume of sp. (20 ml) showed significantly higher μ compared with higher volume (70 and 210 ml cultures).
在水产养殖业中用于喂养鱼类和甲壳类幼虫。众所周知，微藻的种类可能会影响轮虫的产量。本实验旨在确定马来西亚吉打州瓜拉槟榔村渔业研究所（FRI）的五种当地可得微藻物种对轮虫瞬时生长率（μ）的影响。 sp.、 sp.、 sp.、 sp.和 sp.在不同藻类密度（0.1、0.3、0.7和1.5×10个细胞/毫升）和培养体积（20、70和210毫升）下用作饲料。在藻类密度为0.3至1.5×10个细胞/毫升的范围内，所有藻类物种的平均μ值均记录为每天超过0.90。然而，在密度为0.1×10个细胞/毫升时，与其他物种相比，只有 sp.导致了显著最高的μ值（<0.05）。在培养体积方面， sp.较小的培养体积（20毫升）显示出比更大体积（70和210毫升培养物）显著更高的μ值。
