Abstract

Rice eel (Monopterus albus Zuiew), have economical value is high in Banyumas, national to international markets, but rarely is grown intensively, the seed is still dependent on the catch. Reproduction of swamp eel unlike other fish species in the presence of phase teleostei  intersex / hermafroditus and in nature only spawn once a year. This study will seek to accelerate the scale seed production with natural canvas with several techniques triggers lust and sex organ maturation eels based preparedness aspects of reproductive anatomy, hormones estradiol and testosterone profiles and the intrinsic need for hormonal regulation and the mechanism for the reproductive cycle of the eel rice. In the first year aims to determine (1) the profile of estradiol and testosterone hormonal parent during the natural reproductive cycle, (2) histologic gonadogenesis (development of the testes and ovaries) eel rice during the natural reproductive cycle was evaluated by measuring fecundity. Results: In the control group, body weight gradually decreased during the study. Unlike the control group, the treatment groups were observed every two weeks showed an increase in body weight; Results of the study, in the control group (A0), the value of female eels GSI average of the first two weeks until the fourth two weeks is 0.67 % and 1.78%. While the treatment group A1 was 1.42% - 4.28% (DM-1 s / d DM-4), for the treatment A2 GSI average value is 2.52% - 7.05%; fecundity eggs increased during induction period; calibration titer two types of hormones in the first two weeks to the fourth two weeks showed improvement when compared with the control group; histological profile of rice eel gonad after induction of ovaprim-C show that up to the fourth two weeks, gonad has reached late-stage yolk globule (advanced primary oocyte), even the most mature oocyte has reached the stage: in male eels up to the fourth two weeks has reached the stage of spermatozoa

Abstract

Pre domestication research has been done on fish catches from the Serayu river,  Banyumas, lukas fish (Puntius bramoides) and brek fish (P. orphoides) in natural ponds. The parents as pre domestication product is already successfully demonstrated the ability of adaptive in the new environment in terms of aspects of natural food, has been known to their periodically hormonal profiles, profiles of gametogenesis and spawning capabilities in the new environment (natural pond). Further research aims to determine : (1) The degree of eggs hatching of lukas, (2) survival rate of  F2 seeds and (3) the degree of mortality in the floating net on Serayu river. (4) how long it will take and how the ability of the  post spawning F1 parents to be able to spawn again. Research using survey method. Some units of floating net used for maintenance, testing spawning and growth of parents and seeds of lukas. The results : (1) The degree of eggs hatching between 51%-89%; (2) degree of viability of seeds in floating net  is 54%-92%; (3) while the mortality rate of  seeds 8%-48% and (4) the length of time it takes  male and female parents to reach the next spawning period is ± 6 months. The F1 parents spawn after 6 months on a scale of cages.
