Enhancement of Ovarian Development in Striped Catfish (Pangasianodon Hypophthalmus) Through Supplementation of Katuk Extract (Sauropus Androgenus), Turmeric Powder (Curcuma Longa), and Vitamin C

Abstract

The growth and development of ovary in teleost fish will determine the quality of larvae.  This research was designed to accelerate gonad growth of catfish fed ration supplemented with katuk extract (0.6 g/kg), turmeric powder (4.8 g/kg), and vitamin C (599 mg/kg). The experiment was arranged in a completely randomized design with 8 treatments: CON (Control), SA (Katuk extract), TU (Turmeric powder), VC (vitamin C), SATU (Katuk extract and Turmeric powder), SAVC (Katuk extract and vitamin C), TUVC (Turmeric powder and vitamin C), and COM (Katuk extract, Turmeric powder, and vitamin C). The treatmenst were given for 2 months. Parameters measured were body weight, gonad weight, gonado-somatic index, ovary histology, and oocyte diameter. The results showed that supplementations of katuk extract, turmeric powder, and vitamin C produce higher GSI and gonad weights. Oocytes in catfish supplemented with katuk extract, turmeric powder, and vitramin C reached endogenous vitellogenesis phase while in control catfish a number of oocytes were in previtellogenesis phase. Oocytes diameters of endogenous vitellogenesis phase in COMB catfish (603.60±99.09 µm) were higher than those in control catfish (412.60±39.76 µm). Supplementation of catfish with katuk extract, turmeric powder, and vitamin C can accelerate oocytes growth and development and improved quality.
