The residue of 17a-methyltestosterone (MT) in fish has been a concern related to food and the environment safety. This study aimed to determine sex ratio of Nile tilapia treated by MT immersion at 36 °C water temperature, and measure the level of testosterone in fish body. Three hundreds of ten-day-old post hatched larvae was immersed in one liter of water containing 2 mg MT, at 26 °C and 36 °C. Immersion was performed for 2 and 4 hours. The results showed that immersion at 36 °C and increasing immersion time increased male percentage. Higher male percentage was obtained in treatment 4 hours immersion at 36 °C (92.5% male) and the effective treatmen 4 hours immersion at room temperature. By ELISA method, testosterone level in MT treated fish decreased sharply to 88.2% at one month after immersion, and being the same as control without MT immersion. Thus, masculization in tilapia could be performed by MT immersion at 36 °C water temperature for 4 hours, and it is most likely that no MT residual in fish after one month post immersion. Keywords: Nile tilapia, sex reversal, temperature, 17a-methyltestosterone

Ex-tin mining lakes are commonly used by many people in Bangka Island for fish farming activities. The water logs of post mining lakes have been used for fish farming activities. We hypothesized possibly environmental pollution related to the water quality. This paper aimed to evaluate fish farming activities by the local communities using the waterlogs of post mining lakes. The evaluation was based on heavy metals extent in the water using survey method with purposive sampling in order to determine which extin mining lakes would be feasible for aquaculture activities. The data of the content of heavy metals and water qualities were analyzed using the method of Pollution Index (PI). According to the age of mining lakes, the five ex-tin mining lakes which has been observed. The results showed one new aged, two middle aged, and one old age; meets the quality standard eligibility for fish farming activities, while the middle aged was low polluted. The age of ex-tin mining lakes not affected nor the extent of the pollution levels or water qualities.Keywords : ex-tin mining, lakes, aquaculture, water qualities, pollution index, fish

Two life stages of fish were sampled to examine the fish biodiversity and the ecological role of Segara Anakan lagoon (SAL). The fish were observed in during 2004 – 2014 while the larvae were sampled twice monthly during the full moon and dark periods in daylight hours only over 11 month periods (Novembre 2005 to Septembre 2006) at 10 sites located at SAL, Cilacap. Each trip two samples of the high tide and low ebb periods were taken from each station. The mature fish were sampled at Klaces and Karanganyar. The fish were also collected from fisherman. At least 90 genera of 48 family (65 mature fish and 64 larvae) were recorded at SAL. Gobbidae (range between 67.3 – 72.9 %) and Engraullidae (16.7 – 19.3 %) are the two most abundant larvae captured. Of the fish, at least 40 genera belongs to 16 families are of resident species that inhabit SAL for whole their life cycles. In other hand, 50 genera belongs to 31 families use SAL as temporary habitat (migratory). This finding suggests the important ecological role of SAL for fish.Keywords : segara anakan lagoon, biodiversity, ekological role
