FECUNDITY, FERTILIZATION RATE, HATCHING RATE, AND SURVIVAL RATE OF CATFISH (CLARIAS. SP) WITH HATCHERY SEMI -ARTIFICIAL METHOD

aquaculture

Catfish (Known Indonesian name as Ikan lele) has latin name Clarias, sp, it is one of fresh water fisheries in Indonesian is often a commodity fish that have develovement lots of cultivation, and is in great demand by the Indonesian people as fish protein requirement. Based on data from the Central Bureau of Statistics of the Ministry of Maritime Affairs and Fisheries, catfish production on the island of Java experienced a significant increase in 2017 in direct proportion to the increase in public interest. This Field Work Practice will be held in July - August 2022 at the FPIK Teaching Factory, Dipenogor University, Central Java. It was carried out using the observation method, namely making observations, conducting interviews, collecting observational data, and complementing it with literature studies. The purpose of this Field Work Practice (PKL) is to know hatchery techniques, know the survival rate, fish fertilization rate, and hatching rate as a result of catfish hatchery. The results obtained from the fish hatchery process are that catfish have a survival rate of 95%, fertilization rate of 98%, and hatching rate of 86%. Observation of the hatchery process is very important in the scope of aquaculture.
