Abstract
This study aims to determine the effect of usingCassia alataL. leaf extract on the prevention of fungus on fish eggsPangasianodon hypophthalmusThis research was conducted at the Blangpidie Fish Seed Center. Aceh Barat Daya from July to August 2020. Statistical analysis used a completely randomized design (CRD) method with 7 treatment levels and 3 replications. The treatments were conducted by soaking the fish eggs in the leaf extract for 20 minutes. Those treatments were A (control), B (2.5 ppm), C (5 ppm), D (7.5 ppm) E (10 ppm), F (12.5 ppm), and G (15 ppm). ANOVA test results showed that the addition of leaf extractC. alatahad a significant (P <0.05) effect on hatchability and survival ofP. hypophthalmuslarvae. A concentration of 15 ppm is the best with a hatchability value of 85.33% and a concentration of 10 ppm is the most optimum for the survival value ofP. hypophthalmuslarvae, namely 92.99%.
Highlights
Pangasianodon hypophthalmus is one of the potential aquaculture commodities to be developed
As for the types of treatments tested were as follows: A=immersion without C. alata leaves extract (0 ppm); B= immersion with C.alata leaves extract at a dose of 2.5 ppm; C= immersion with C.alata leaves extract at a dose of 5 ppm; D= immersion with C.alata leaves extract dose of 7.5 ppm; E= immersion with C.alata leaves extract at a dose of 10 ppm; F= immersion with C.alata leaves extract at a dose of 12.5 ppm; G= immersion with C. alata leaves extract at a dose of 15 ppm
Based on the results of the study, it was found that the use of C. alata leaf extract could increase egg hatchability and survival of P. hypophthalmus (Table 1), where the higher the dose of extract used in the treatment will increase the hatchability of fish eggs
Summary
Pangasianodon hypophthalmus is one of the potential aquaculture commodities to be developed. Efforts to control disease in cultured fish eggs due to pathogenic infections that use chemicals or antibiotics in the long term can have negative impacts, among others, can cause bacterial and fungal resistance and can pollute the environment [3,4]. One of the natural ingredients that has the potential to inhibit the growth of pathogens in fish is the use of Cassia alata leaves. This plant is known by different names in different countries, namely as Gelenggang (Malaysia), Ketepeng Badak or Ketepeng Cina (Indonesia) and bush ringworm (Australia) and has been used as as traditional medicine to treat various diseases [5,6]
