Abstract

Gonad maturity in fish is essential in fish farming because it is related to seed production. Sesame oil is one of the ingredients as a feed supplement to stimulate fish gonad maturation. The research aimed to obtain the best dose of sesame seed extract (Sesamum indicum L.) in feed to increase the gonad maturity of comet fish (Carassius auratus). This research had four treatment levels and three repetitions. The treatment levels in this study were: P0 Without giving sesame seed extract (Control), P1 Giving sesame seed extract 5 mL/kg feed, P2 giving sesame seed extract 10 mL/kg feed, P3 Giving sesame seed extract 15 mL/kg. The results of the six-week study showed that at the beginning of maintenance, they were in TKG I, in the 3rd week, they entered TKG III, and in the 6th week, P1, P2, and P3 entered TKG IV while P0 were still in TKG III. The highest gonad maturity index at each observation time occurred in treatment P2 with feed containing 10 mL/kg of sesame seed extract. In the 1st week, the highest gonad maturity index occurred at P2 at 7.80. In the 3rd week, the highest gonad maturity index occurred in P2 at 9.26%. In the 6th week, the highest gonad maturity index occurred in P2 at 11.17%. Fecundity at week 6 showed the highest result of P2 4,290. The level of gonad maturity with treatment given sesame extract was faster, with a maintenance time of 6 weeks. The results of this study illustrate that sesame extract can be used as a supplement to increase comet fish gonad maturity.

Abstract

Cyprinus rubrofuscus has high economic value as a freshwater ornamental fish, in demand in the international market. The growth of koi fish can be increased by adding probiotics to the feed. This addition can benefit fish health and water quality if given in the correct dose. This study was conducted to see the effect of different doses of probiotics in the feed on koi growth. The study was conducted from February 2023 to February 2024, with treatments administered from May 28 to July 7, 2023. The design was a Completely Randomized Design (CRD) of four treatments (PB0, PB10, PB15, PB20) with three replications. The parameters measured included growth in length, weight, specific growth rate, and survival. At the end of the study, it was found that adding probiotic doses had a significant effect (P < 0.05) on weight, length, and specific growth rate, but did not affect survival. The PB15 dose gave the best results, with a weight gain of 0.46 ± 0.66 g and a particular growth rate of 1.88 ± 0.11% per day.

Abstract

Ectoparasite infections frequently affect gourami fish during the seed (juvenile) phase. Immersion in piper betle extract can be a natural alternative treatment to reduce ectoparasitc infections by utulizing its bioactive compounds. This study aims to identify and analyze the prevalence and intensity of ectoparasite infecting juvenile gourami. The experimental design consisted of four treatments with three replications each. Treatment P1 (control), treatment P2 (piper betle extract at 150 mg/L), treatment P3 (piper betel extract at 200 mg/L), and treatment P4 (piper betle at 250 mg/L). The findings indicated that treatment P3 was the most effective in reducing the prevalence of Trichodina sp. (40%) and Dactylogyrus sp. (53%), and also achieved a survival rate of 90%. Treatment P4 was able to reduce the prevalence of Gyrodactylus sp. by 20%, as well as the Trichodina sp. (%), Gyrodactylus sp. (%), and Dactylogyrus sp. (%). However, the growth in length, absolute weight gain, and feed conversion ratio (FCR) were not significantly affected. The types of ectoparasite were found to infect juvenile gourami: Trichodina sp. (prevalence 40% and intensity 5 ind./fish), Gyrodactylus sp. (prevalence 20% and intensity 1 ind./fish), and Dactylogyrus sp. (prevalence 53% and intensity 2 ind./fish).
