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

The research was aimed to figure out the survival rate and the regeneration rate of  the sea cucumber, Stichopus hermanii, seeds generated from the  transverse fission method.  The research was conducted in the Talengen Gulf, the District of Sangihe Islands, at the field research station of the Nusa Utara State Polytechnic.  The tested animals, Stichopus hermanii, were collected from the waters around the Talengen Gulf.  Specimens of the sea cucumber, lengthened 9 to 15cm, were transported by boat to the site of the experiment and kept in plastic mesh-cages. Fourteen individuals then were transversely tied in the middle of the body antero-posteriorly to induce fission, hence there were 28 new individuals were generated, which were composed of 14 anterior seeds and 14 posterior seeds.  The seeds then were kept in 6 plastic mesh cages, where the anterior individuals were separated from posterior ones.  The cages were placed at the bottom of the sea waters where the sea cucumber might have access to substrate and sea grasses around the cages.   The time required by the newly fissioned cucumbers to seal off the open wound, the wound recovery time, the survival rate of the seeds and the regeneration  rate of the new integument connective tissue were among the data collected during the experiment.   The regeneration rate of the new integument connective tissue was indicated by development of a protuberance at the median of the healed wound.  The results show that the survival rate of the Stichopus hermanii seeds generated from transverse fission method were 100% for 40 days post-fission.   The average time for the newly cut cucumber to seal off the open wound is 4 minutes.  The average time for the seeds either anterior or posterior individuals, to recover the wound is aroung 25-28 days.  The protruberance of the newly regeneration integument connective tissue is appeared at day 30.  There is no significant difference between anterior and posterior seeds in regenerating the protuberance of the new integument connective tissue, after 40 days post-fission.Keywords:  asexual, reproduction, transverse fission, survival rate, regeneration

Abstract

This research aimed to determine the stocking density that support the best growth and survival rate of carp cultivated in aquaponic systems, and to study the water quality of carp culture with different stocking densities in aquaponic systems. The study used 12 aquaria measuring 40x40x40 cm each (water volume of 50 liters). The experimental fish are carp (Cyprinus carpio) weighing in average of 3.5 g/individual.  The fish were cultivated with different stocking densities as treatment, including A = 4; B = 7; C = 10 and D = 13 individuals/aquarium.  The fish were fed with pellet at 5%/body weight/day with a feeding frequency of two times a day. The study was conducted for 4 weeks. Data consisting of daily growth, survival and water quality parameters (temperature, pH, dissolved oxygen, ammonia, nitrite and nitrate) were measured once a week. The data obtained were analyzed by ANOVA. The results of the study showed that the difference in stocking density had no significant effect on the growth and survival of carp.  Water quality was in a reasonable range to support the growth and survival of carp cultivated with aquaponic systems.Keywords: cultivation, carp, aquaponics, stocking density, growth
