Abstract

The cantang grouper is a hybrid of the tiger grouper and the cantang grouper. The canting grouper has qualities that make it desirable for further development, including rapid growth, disease resistance, and environmental tolerance. This research aims to determine the embryological process and the hatching rate (HR) results. This research was carried out from September 1 to December 30, 2023, at Balai Perikanan Budidaya Air Payau (BPAP) Situbondo. The method used in this research is a descriptive method obtained from primary data and secondary data. The quality of larvae from the hybridization of tiger grouper fish (Epinephelus fuscogutattus) and kertang grouper fish (Epinephelus lanceolatus) was obtained through embryology and hatching rate observations. This research concludes that rearing hybridized canting grouper larvae includes several processes: egg development, egg harvesting, preparation of rearing tanks, egg stocking, hatching rate, observation of larvae, feeding management, water quality management, and disease management. The Hatching Rate (HR) percentage obtained was 82%, which is classified as high quality according to SNI standards.

Abstract

Tilapia, also known as Oreochromis niloticus, is an important commodity in Indonesia that contributes to national food security, economic sustainability and community welfare. The aim of this research is to determine techniques for rearing tilapia cultivation using an aquaponic system. The aquaponics system uses water from fish farming ponds which is channeled through pipes for cultivating plants. This research uses an observation and active participation methodology, namely going directly to the field during tilapia (Oreochromis niloticus) rearing activities using an aquaponic system at OPO Q Farm Cacaban, Magelang City. The research results show that the aquaponics system is an effective method for cultivating tilapia. The process includes preparing the tilapia cultivation container, lettuce plant container, sowing the lettuce plants, stocking the fish, filling the lettuce seeds into the netpot container, providing food, and checking the water quality. The aquaponics system produced a high FCR of 1.06 tilapia, a survival rate of 99%, and a lettuce yield of 47.5 kg. The water quality of the aquaponic system is considered ideal, with temperatures ranging from 23-26°C, pH 6.5-7.5, DO 5.74-6.76 mg/L, and Ammonia 0 ppm. Lettuce plants effectively absorb food and fish metabolic waste, thereby ensuring that the water quality in the aquaponic tilapia cultivation medium is maintained.
