Blue tilapia (Oreochromis aureus) has known as euryhaline species refers to wide range of salinity tolerance. The pure population or hybrid with other strain of tilapia can be a good candidate in marginal coastal land use. Tilapia is the most important aquaculture species in Indonesia. Refers to FAO 2010, Indonesia is the third biggest of tilapia production after China and Egypt. One of the main problems in aquaculture is their feed as the major cost in fish farming. Various techniques had carried out to reduce of feed cost such as improving fish quality, sex reversal and feed management. This research aimed to determine of compensatory growth in tilapia as one technique in feed management. Fry obtained from natural spawning in freshwater pond. Acclimatization in 20 ppt made in aquarium for 4 days after one month reared in hapas. Fish reared in 2 m x 1 m hapas with five treatments and three replications. This research had conducted at brackish water pond in Yogyakarta. The treatments is A: one day fasting and six days feeding (1/6), B: 2/5, C: 3/4, D: 4/3 and E is control. Results showed that the biggest of average weight gain is treatment of E (68.36 g) followed by A (66.38 g), B (62.44 g), C (43.56 g), and D (27.30 g) respectively. One-way ANOVAs analysis with 95% of interval confidences continued with Tukey’s Pairwaise comparison showed that nothing significant different between E, A, and B. The biggest of daily growth rate and specific growth rate is E (0.75 g/day and 4.68 %bw/day) followed by A (0.73 g/day and 4.65 %bw/day); B (0.69 g/day and 4.58 %bw/day); C (0.48 g/day and 4.18% bw/day) and D (0.29 g/day and 3.65% bw/day) respectively. Survival rate of A is 73.00% followed by E. 72.00%, C. 71.00%, D. 69.69%, and B. 67.00% respectively. Feed conversion ratio of D is 0.83 followed by C (0.87), B (0.98), A (1.16), and E (1.41). Food efficiency ratio of D is 127.06% followed by C (118.75%), B (106.09%), A (88.87%), and E (73.38%). These results indicate that fasting of one day and two days has no significant effect on fish growth. Treatment A and B is the better treatment for fish culture refers to the better value of FCR, FER, and total weight gain.

ABSTRACT The »early-androgen« syndrome in the rat – i. e. anovulatory ovaries in adult females after a single injection of testosterone propionate (TP) within a week of birth – may not become apparent until some time after the attainment of sexual maturity. Large doses (50 or 100 μg) of TP were effective earlier than lower doses (5 or 10 μg). Rats which received 5 μg TP were ovulating at 10 weeks of age, mated but were infertile at 13 weeks of age, and were anovulatory at 21 weeks. In rats between 10 and 13 weeks old there was a marked fall in the number of corpora lutea in the ovaries of animals which had been given 5 μg TP. Hemi-spaying was followed by compensatory growth of the remaining ovary which consisted of corpora lutea in ovulating, and of follicles in anovulatory rats; little or no compensatory weight increase occurred in animals which seemed to be in the transition stage from the ovulatory to the anovulatory condition.
