Abstract

This study was conducted to determine the optimal dose of propolis for male sex reversal in tilapia larvae through mixing in artificial feed. This research was carried out at the Aquaculture Technology Laboratory, Faculty of Fisheries and Marine Sciences, Sam Ratulangi University. The experimental fish was taken from Board of Freshwater Fisheries Aquaculture at Tatelu. As many as 4,000 individuals fish aging 5 days were acclimatized for 2 days in an aquarium measuring 60 x 40 x 40 cm. After the acclimatization process was terminated, the larvae density was set to 100 per aquarium. Furthermore, the fish were fed with treatment feed previously added with propolis with a dose of A (0 mL/kg of feed) as a control, B (0.9 mL/kg of feed), C (1.8 mL/kg of feed), D (2.7 mL/kg of feed) and t E (3.6 mL/kg of feed). Treatment feed was given to larvae twice a day for 28 days. The results showed that masculinization of tilapia using propolis mixed into artificial feed had a very significant effect on the percentage of male tilapia and survival. In this study treatment C (1.8 mL/kg of feed) and treatment D (2.7 mL/kg of feed) resulted in the highest percentage of male tilapia which was 81.33% and 88.00% respectively. This shows that the administration at 1.8 mL/kg in artificial feed has a very real and effective effect on masculinization.Keywords: Oreochromis niloticus, masculinization, sex reversal, propolis

Abstract

This study aimed to determine the effect stocking density on growth and determine the effect on the survival of saline tilapia. The experiment was conducted at the Aquaculture Technology Laboratory and the time of the study was from February to August 2021. The experiment was designed according to a completely randomized design (CRD) with 4 treatments and 3 replications so that there were 12 experimental units. The factors tested were differences in stocking density of tilapia with treatment A: 10 fish/20 liters, treatment B: 15 fish/20 liters, treatment C: 20 fish/20 liters, and treatment D: 25 fish/20 liters. Growth data and survival rate (%) were analyzed using analysis of variance for RAL, then LSD test (Least Significance Different) was performed. Observations of water quality include temperature, DO, pH, and salinity. The result of the analysis of variance showed that the difference in stocking density had a significant effect on growth, but on the survival rate had an insignificant effect. The results of the BNT test on growth showed that treatment A was not significantly different from treatments B and C, but treatments A, B, and C were significantly different from treatment D. The temperature range during the experimental period was between 29 0C – 30.9 0C, DO ranged from 4.07 ppm – 6.80 ppm, pH between 6.78 – 7.95, and salinity 25 ppt

Abstract

This research was conducted to examine the survival and regeneration success rate of the Brown Sandfish (Bohadchia marmorata) using the Transverse-fission method in containers placed in nature and controlled. This research was conducted  from June to July 2021, in Bahoi Village, West Likupang, North Minahasa. This research used the Transverse-fission method, in which B. marmorata was tied using a rubber band until cleavage occurred. The container used is a basket covered with a net as many as 6 units, each of which is insulated in the middle so that it becomes 12 parts. Individuals who have been tied, then observed for changes shortly after the binding is done until the individual is separated (every 1 - 2 hours), followed by observing the survival and regeneration of separate body parts (every 6 hours). The results of the study were then analyzed using SPSS 22 version with T-test.  Based on the results of the research, the survival and regeneration success rate of B. marmorata using the Transverse-fission method placed in containers in natural waters was significantly different from that of B. marmorata placed in controlled containers, where the total survival rate of B. marmorata placed in in controlled containers reached 100% while the total survival rate of B. marmorata placed in natural waters only reached 3.33%.

Abstract

This study aimed to determine the effect of different doses of EM-4 in feed on the growth and survival of tilapia. This research was conducted at the Center for Freshwater Aquaculture (BPBAT) Tatelu. The study was carried out from June to August 2021. The experimental design used was a Completely Randomized Design (CRD) with 4 treatments and each treatment had 3 replications. The treatment used was Probiotic EM-4 with different doses consisting of: A: 0 ml/kg feed, B: 15 ml/kg feed, C: 20 ml/kg feed, D: 30 ml/kg feed. The results of the study used the Analysis of Variance (ANOVA) using the SPSS application (22). Giving different doses of EM-4 in the feed gave a significantly different effect on the absolute weight growth of tilapia, but the results also showed that the administration of different doses of EM-4 in solid had no effect on absolute length growth, daily length growth rate, FCR and tilapia survival. The treatment that had an effect on the absolute weight growth of tilapia was found in the treatment with a dose of EM-4 15 mL/kg of feed with an absolute weight growth of 23.89 g.
