  1. EFFECT OF CRUDE EXTRACT SAMBILOTO (Andrographis sp) LEAVES IN CONTROLLING REPRODUCTION OF FEMALES SALINE TILAPIA (Oreochromis niloticus) OLEH • MOHD. SYAICHUDIN,S.IK, M.Si • SUHARDI ATMOKO BS, S.Si • ABDUL GAFUR, S.Pi It presented in Asian Pacific Aquaculture 2016 at 26-29 April 2016 in Grand City Surabaya CENTER FOR BRACKISH WATER AQUACULTURE DEVELOPMENT TAKALAR– SOUTH SULAWESI - INDONESIA

  2. INTRODUCTION • The classic problem of the saline tilapia farming are maturity before adulthood and mating behavior. • This behavior is often inhibits growth and reduce the productivity of aquaculture. • This condition is spurring the development of a variety of techniques to control the reproduction of tilapia in aquaculture.

  3. One of the materials is herbal extracts, beside safe for human also cheap. • By controlling the reproduction of tilapia aquaculture, is expected that we can obtain better growth, • We think that the fish will divert more energy to growth rather than reproductive behavior.

  4. An alternative method for controlling reproduction, is the use of herbs as alternative for proper substitution of chemicals such as bitter (Andrograhissp). • The active compound andrographolida cause infertility through the mechanism of inhibition of the production of progesterone play a role in the maturation of the gonads. copy females

  5. OBJECTIVE This research will examine the role of the crude extract of bitter (Andrograhissp) in the control of gonadal maturation saline tilapia females

  6. METHODOLOGY

  7. Formula for Absolute Length Growth (Lm) of fish (Efendie, 1979) Lm  =   Wt - Wo Where : Lo  =   initial length (cm) Lt   =   final length (cm) Formula for Absolute Weight Growth (Wm) of fish (Efendie, 1979) Wm  =   Wt - Wo Where : Wo  =   initial weight (g) Wt   =   final weight (g)

  8. RESULT AND DISCUSSION It appears that the bitter can suppress gonad maturity level in saline tilapia females up to 18.75% compared to the controls below (without addition of sambiloto)

  9. It appears that all females saline tilapia on control tank had gonad maturity level up to 100% compared to the treatment tank (with addition of sambiloto)

  10. The diffrence 18.75 %

  11. The absolute length growth of control 6.05 cm while the treatment of sambiloto 6.88 cm, it seen that sambiloto treatment is slighly higher 0.83 cm. • While the absolute weight growth on the using bitter that is 161.56 g compared with controls that is 142.03 g, it is also look slightly higher 19.53 g. • The level of gonadal maturity on control reaches 100%, while on bitter treatment 81.25%. • It is proved that the extract of bitter in this activity could inhibit gonadal maturation in the saline tilapia females around 18.75%.

  12. Data for Fish Growth

  13. Phytoestrogen compound is believed that have the ability as the sex hormones, and can block estrogen biosynthesis by acting as aromatase inhibitors and estrogen receptor antagonists in gonadal germ cells. • Therefore, this material is considered potentially useful in encouraging sex reversal or delay gonadal maturation in fish, especially in the control of reproduction of tilapia in aquaculture so that productivity will increase.

  14. CONCLUSION

  15. SUGESTION
