Abstract

This research aimed to determine the optimal doses of honey addition on the sperm dilution to optimize spermatozoa motility, fertilization and hatchability of Patin Siam  eggs (Pangasius hypophthalmus).  The experimental design used was Complete Random Design (RAL).  Diluent solution consisted of a physiological NaCl 0.9% and honey.  Treatment doses of honey in aqueous diluent sperm tested as treatments were A (0 mL), B (0.2 mL), C (0.4 mL) and D (0.6 mL), each with three replications.  Observations made included spermatozoa motility, fertilization and eggs hatchability.  The research results showed that the addition of honey had a significant influence on motility,  fertilization, and eggs hatchability. This study concluded that the addition of honey in sperm diluent solution with a dose of 0.6 mL of honey in 99.4 mL of NaCl could increase the spermatozoa motility and  fertilization of Patin siam. Keywords:  honey, motility, fertilization, hatchability,  Pangasius hipophthalmus

Abstract

The purpose of this study was to determine the best culture medium for producing maggot (Hermetia illucens) and to determine the production quantity in each different medium.  This research was controlled two times a day at 09:00 a.m. and 16:00 p.m. Cultivation media were prepared from coconut pulp, tofu pulp, rice bran and restaurant wastes. Each medium was weighed as much as one kg and then placed into a culture container. The research used Completely Randomized Design consisting of 4 treatments, each with three replications. The parameters observed consisted of temperature and pH of the media  measured at 07.00 am and 17.00 pm, and maggot production measured on the last day. During the ten days of experiment, the production of maggot in the treatment using restaurant waste media was significantly different as compared to other treatments. This study found that a good medium for the production of maggot was prepared using restaurant waste. Keywords: Hermetia illucens, coconut pulp, restaurant waste

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 held on May 7th – 30th 2021 in the Aquaculture Technology Laboratory at the Faculty of Fisheries and Marine of Sam Ratulangi University with the objectives were to determine tilapia fish fillet waste flour’s substitution impact for the growth of the seed and to determine the impact of the tilapia fish fillet waste flour towards the feed’s efficiency. The research lasted for three consecutive weeks. Fish culture container was plastic container with the height of 50 cm and the width of 30 cm for the total of 18 pieces containers. Each container was flowed by 10 liters of water. Fish used had a size of 3 to 5 cm with a weight of 1 gram for each tilapia and stocked as many as 10 fish in each container. The pellets used was flour pellets of tilapia waste fillet with different compositions. Each container was labeled alphabetically: A (0%), B (10%), C (30%), D (30%), E (40%), and F (50%). Frequency of feeding was 3 times a day (08:00 AM, 12:00 AM and 04:00 PM) with a feeding dose of 10%. Water was changed every 4 days. Growth observation was conducted every week using digital scales 0,1 gram. Experimental contrivance was random contrivance exhaustive. Analysis used analysis of diversity. The observed data included relative growth and feed efficiency values. The result showed treatment E gave a better relative growth response and feed efficiency value than other treatments.

This study aimed: (1) to analyze the physical and chemical parameters of water quality of the giant travelly fish (Caranx sp) culture area in floating net cages (KJA) in Tuntung Timur Village, Bolaang Mongondow Utara Regency, and (2) to analyze the feasibility of water quality of the giant travelly fish (Caranx sp) in east Tuntung Village, North Bolaang Mongondow Regency. The  physical and chemical parameters of water at the cultivation site of Caranx sp in floating net cages were measured in situ, including temperature, salinity, brightness, dissolved oxygen and pH. Chemical physics parameters in floating net cages, namely: temperature ranges from 28.6 oC - 33.3 oC, salinity 30 - 33 0/oo, pH 7.6 - 7.9, oxygen content 3, 9 - 4.3 mg / l and water transparency of 7.4 m - 9.9 m. The giant travelly fish aquaculture in KJA in east Tuntung village is an enlargement activity, the seeds were stocked from bagan and the surrounding waters, the size of the seeds ranged from 8-12 cm, and the stocking density was 500-600 fish. Maintenance was carried out for 5-6 months and harvested at sizes 300-4000 gr/individu. The water quality surrounding KJA was ideal for fish farming activities.

Abstract

The purpose of this study were (1) to determine the morphometric characteristic of pearl oyster Pinctada margaritifera in Arakan, Mantehage Bango, and Talengen waters of North Sulawesi Province, (2) to determine the ideal location for the feasibility of pearl oyster culture. Determination of the sampling location is done by purposive sampling. The shell morphometric dimensions measured were shell length, shell height, hinge length, shell thickness and shell weight. The measured water quality were temperature, salinity, dissolved oxygen, pH, and depth. The morphometric characteristic of P. margaritifera oyster in Arakan waters have shell length (PC) ranging from 44,25 – 169,77 mm with an average of 86,50 mm, Mantehage Bango waters  have PC ranged from 38,73 – 106,09 mm with an average of 80,31 mm, and Talengen waters have PC ranged from 25,89 mm to 105,34 mm with an average of 68,97 mm. Arakan waters are dominated by medium size P. margaritifera (53,78%), it is suspected that Arakan waters have pearl oyster stocks in nature for aquaculture activities. Evaluation of the suitability of waters for pearl oyster culture P. margaritifera in Arakan waters scored 77,7% categorized as suitable (S2), the location of Mantehage Bango waters scored 80% categorized as suitable (S2) and the location of Talengen waters 68,8% categorized as conditional (S3).

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
