Abstract

This study was conducted to determine the level of aquaculture production Tondano and determine the impact of the production level of the waters of Lake Tondano nutrifikasi . The data collected in this study , consisting of primary data and secondary data . Production data obtained from the questionnaire and interviews to farmers fish there , as well as data obtained from the Department of Fisheries and Village Head Office . Water sampling to determine levels of phosphate in the waters of the lake . Water sampling conducted on six (6 ) locations: Village Ranomerut , Eris Village , Village Paslaten , Leleko Village , Village and Village Paleloan Toulour . Sampling was conducted at six (6 ) points to pay attention to the position of the inlet and outlet of the waters of Lake Tondano . Tondano aquaculture production in 2014 was estimated at 1222.12 tons / year . Number KJT operated as many as 978 units . There was a decrease in aquaculture production annually over a period of 2001 - 2014. Followed by the declining number of KJT on Lake Tondano . Phosphates were donated to the waters of fish farming activities from the rest of the feed pellets . The content of orthophosphate in the waters of Lake Tondano of 0.06 mg / l means the waters of the lake are in a safe condition Tondano not pass the specified limits ( PP RI No. 82 of 2001 ) . The decline in aquaculture production decline followed Tondano phosphorus content in Lake Tondano . Another factor that is expected to also affect the amount of water hyacinth around the lake so that the phosphorus content is also on the wane. Keywords : Production, Lake Tondano, Nutrification

Abstract

The aim of the research was to find out the growth rate of the marine lobster, Panulirus versicolor, fed different types of diets.   The experiment was conducted at the Laboratory of Aquaculture Technology, Faculty of Fisheries and Marine Sciences, Sam Ratulangi University.  The experiment was set up  in 3 treatments, which were three different types of diet: treatment-A: papaya leaves, treatment-B: coconut flesh, treatment-C: skipjack-fish flesh.  Each treatment was triplicated.  The tested lobsters were collected from the marine waters of the Likupang village, North Minahasa Regency.  The tested lobsters were weighed at the beginning,  at the end of the experiment, and at the interval of 14 days during the experiment period. The data of the body weight change were statistically analysed using the analysis of the homogeneity of the 3 different linear regression coefficients, between time (X) and the body weight of the lobsters (Y) fed different types of feed, at the confidence test level a = 5% and 1%.  The results show that the body weight of the tested lobsters fed skipjack-fish flesh increased 4 grams after 30 days of the rearing period.  The body weight of the tested lobsters fed papaya leaves decreased 11 g, and the body weight of those fed coconut flesh decreased 3 g after 30 days of the rearing period.  The result of the regression analysis shows, the assumption that the 3 regression coefficients are homogenous is rejected.  In other words, there is a significant difference among the growth rates of the tested lobsters fed different type of diets.  Compared to skipjack-fish flesh, the papaya leaves and coconut flesh significantly slow down the level of the water quality degradation during experiment period.Keywords:  diets, growth, marine-lobster

Abstract

The aims of the research were to find out firstly, the growth rate of the mud crab Scylla Serrata) reared under different salinity levels and secondly, the range of the salinity where the mud crab optimally grows.   The experiment was conducted at the Laboratory of Aquaculture Technology, FPIK, UNSRAT, from April to May 2017.  The experiment was set up according to the Randomized Block Design, with 3 treatments, which were 3 different salinity levels, 10 ppt, 20 ppt and 30 ppt.  The tested level of salinity was determined based on the preliminary experiment.  Each treatment was triplicated, and each replicate represents the group of the initial weight of the tested crab, which was 80-89 grams (group-1), 70-79 grams (group-2), and 60-69 grams (group-3).  The tested mud crabs were collected from the estuarine waters of Inobonto river, which has salinity level of 12 ppt.  The tested crabs were weighed at the beginning and at the end of the experiment, and at the interval of 7 days during the experiment period.  The weight of the tested crabs data were converted into Absolute Growth Rate (AGR) and Daily Growth Rate (DGR), which in turn were statistically analyzed using Anova for Randomized Block Design, and then Least Significant Difference Test.  The results of the Least Significant Difference Test show that the absolute and daily growth rate of the tested crabs in the salinity of 10 ppt are not significantly different with those in the salinity of 20 ppt.  While the lowest absolute and daily growth rate of the tested crabs were in the salinity of 30 ppt and are significantly different with those in the salinity of 10 and 20 ppt.  Hence, in order to get a maximal production, the mud crab, Scylla serrata, should be cultured in the waters with a range of salinity between 10 and 20 ppt.Keywords: Mud crab, salinity, growth

Abstract

The aim of the experiment was to find out the survival rate of the sea cucumber (Stichopus hermanni) seeds generated from transverse-fission method, and cultured in the waters of Talengen gulf, Sangihe Islands Region.  Twenty five specimens of sea cucumber were collected around the waters of Talengen gulf and Pananuareng bay, the Region of Sangihe Islands.  The specimens were transported by boat to the field-research area of Nusa Utara Polytechnic, as the site of the experiment.  The specimens were kept individually in 25 plastic mesh cages, where each cage measured 40cmx40cmx40cm.    The individual body length of the specimens was measured  and then  was transversely  cut at the middle of the body antero-posteriorly.  The procedure was conducted underwater to prevent  expelling of the visceral organs.  25 individuals were applied transverse-fission,  hence 50 new individuals were generated, which were composed of 25 Anterior individuals (A) and 25 Posterior-individuals (P).   After transverse fission,  the Anterior- individuals (A) and Posterior-individuals (P), generated from the same individual were put back to their previous cage.  The new individuals were cautiously controlled, and at the interval of 6 hours observation on the sealing process of the open wound and the regenerating process were carried out. The result showed that the survival rate of the sea cucumbers generated from transverse-fission method, was as high as 70.83%.  The Posterior-individuals (P) had higher survival rate (75.66%) than Anterior-individuals (66%).   The result also showed that A and P individuals generated from larger individuals had lower survival rate than those from smaller individuals.   Small individuals sizing 6-14cm had highest survival rate, which was 100%, while larger individuals sizing 14-22cm and 22-30cm had lower survival rate which were 85.5%  and  27% respectively.     The sealing of the open wounded took averagely 4 days, while the process of the regeneration took around 4 weeks. Keywords: sea-cucumber, fission, survival-rate

Abstract

The research is aimed to assess the carrying capacity of the Tutud Lake waters,  to ensure a sustainable aquacutural production.  The carrying capacity of the Tutud lake was assessed using the method developed by Beveridge (2004), where several parameters of water quality, aquacultural production, and the physical condition of the lake physic  such as, the dimensions of the Lake, flushing rate, total phosphate [P], total aquacultural production per year and Food Conversion Ratio (FCR), were required in the assessment. Collected data were, then, analyzed using the procedures of calculation, which were combined with the several assumptions and modeling based on the previous research (Beveridge, 2004).  Water sample  for phosphate [P] analysis were collected four times with an interval of 7 days, and undertaken at four different positions which  representing the overall water condition of the lake.  Ammonia, Nitrite and Nitrate content of the waters were measured twice with an interval of 1 month.  Daily fluctuation measurements were undertaken for DO, pH and temperature.  Aquacultural protocols and production data were collected using questionnaire and by direct observation at the farm. The result shows that the average phosphate [P] content of the waters of Tutud lake is as high as 1,068 mg/L, which surpasses the maximum recommended value for waters used for aquacultural production.  DO is at the range of 2,2 – 5,0 mg/L, while temperature ranges from 25,3oC to 29oC, and  pH value varies between 6,38 and 7,89.  Average Nitrite content, 0,004mg/L, and Nitrate content,  4,51mg/L, of the waters of  Tutud Lake are at the safe level for aquaculture.  On the contrary, Ammonia content, 0,34mg/L, and H2S content, 0,681mg/L, of the Lake are at the insecure level for aquaculture animals.  Total aquacultural production per year in Tutud Lake , around 22,5 tons of fish per year, is also surpasses the carrying capacity of the waters of the Tutud  Lake which is only as high as 21,48tonnes.  Hence, the total production for the coming year must be reduced as many as 1,02 tones.Keywords: carrying capacity, water quality, production, Lake Tutud, TombatuABSTRAKPenelitian ini bertujuan untuk mengetahui kapasitas produksi optimal untuk menunjang aktivitas akuakultur yang berkelanjutan di danau Tutud dengan menggunakan parameter fosfor.

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
