    Abstract

    Ketam nipah (genus Scylla spp.) merupakan sejenis krustasea yang penting dari segi pengkomersilan. Namun, salah satu halangan utama untuk perkembangan akuakultur ketam Scylla adalah kekurangan bekalan anak benih yang ditetaskan dalam pusat hatceri penetasan disebabkan isu-isu utama iaitu penyakit disebabkan bakteria dan kadar kematian yang tinggi. Pada masa kini, antibiotik digunakan secara meluas dalam penternakan larva ketam nipah untuk mempertingkatkan kelangsungan hidup dan bekalan yang berterusan. Walau bagaimanapun, penggunaan antibiotik untuk jangka panjang menimbulkan pelbagai risiko, termasuk pembangunan rintangan bakteria terhadap antibiotik, tahap kebisaan, dan pengesanan bahan kimia dihadkan dalam daging binatang yang diternak. Tujuan kajian ini adalah untuk menggunakan tiga jenis probiotik, iaitu Bacillus pelbagai jenis, Lactobacillus casei (Shirota), dan Lactobacillus plantarum, pada kepekatan yang berbeza untuk menentukan prestasi kultur di larva Scylla paramamosain. Mud crabs (Scylla spp.) are commercially important crustaceans. One of the major obstacles to the growth of Scylla aquaculture is the low supply of hatchery produced seed due to bacterial diseases and high rates of mortalities. Currently, antibiotics are used extensively in Scylla larval culture to improve survival, but its use poses numerous risks including the development of resistance in bacteria to antibiotics, higher levels of virulence, and detection of restricted chemicals in the flesh of farmed animals. The aim of this study was to determine the culture performance of Scylla paramamosain larvae with the use of three different types of probiotics, namely a multispecies Bacillus, Lactobacillus casei (Shirota), and Lactobacillus plantarum, at various concentrations.
