Histological analysis of ovarium development of Hampala macrolepidota Kuhl & Van Haselt, 1823 from Jatigede Reservoir, West Java

This research was conducted from May to September 2018 at the Biotechnology Laboratory, Faculty of Fisheries and Marine Sciences, University of Padjadjaran. Fish samples were taken from Jatigede Reservoir, Sumedang, West Java. The hampala fish consisted of female hampala barb with gonadal maturity level (GML) IV, GML V, and GML VI. Ovarian histological preparations were made at the Animal Microtechnical Laboratory, Faculty of Mathematics and Natural Sciences, Universitas Padjadjaran. This research aimed to determine the stages of ovarian development of hampala barb, and determine the types of spawning. The hampala barb in the Jatigede Reservoir had five stages of oocyte development, namely chromatin nucleolus stage, perinucleolus stage, cortical alveolus stage, vitellogenesis, and oocyte maturation with multi-spawner group synchronous type of ovarian development.
