Fighting fish (Betta sp.) is endemic fresh water fish of Southeast Asia that has become one of Indonesias export commodities. Male fighting fish has brighter colour then the female. Mono-sexual male fighting fish population can be obtained through sex reversal method (female to male). However, male fighting fish suspected sex reversal results will likely have a low color intensity. This study aims to determine the effect of sex reversal using 17α-methyltestosterone hormone toward colour intensity of male fighting fish with XX genotype as the results of sex reversal and the original male fighting fish XY genotype. The research design consisted of 2 treatments with 3 replications. The determination of the observations grade toward the colour intensity of fighting fish is done by comparing the original colour of the fish using coloured paper Modified Toka Colour Finder (M-TCF) which were observed by 5 observers for the accuracy of the data. The results showed that there is significant effect of sex reversal using 17α-methyltestosterone hormone toward the colour intensity of the male fighting fish XX to XY males. On the whole, the mean observed colour intensity for P1 (with sex reversal) is 18.33 and P2 (without sex reversal) is 28.33, it shows that the P1 has lower brightness than P2.

Bumi Dipasena Sejahtera as part of Bumi Dipasena, which is managed by PT. Dipasena Citra Darmaja is the largest shrimp farming in Southeast Asia. Since operating in 1980, Bumi Dipasena has made production up to 200 tons/day. However, the current condition shows a decrease in total production to 30 – 40 tons/day from 16.000 operated ponds. Decreasing production is caused by declining water quality. This study aims to find out about nutrient loading and water suitability based on water quality criteria. Nutrient loading is determined from total production calculated from three different ponds. Suitability analysis was conducted by matching and scoring methods based on water quality measured at 7 sites in the inlet, outlet, and pond site. The result shows that nutrient loading has the highest value at the highest production. Water suitability analysis both of inlet and ponds include in suit marginal class (S3).
