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

Abstract

"Gemusis" fish cultivation group is one of the aquaculture business groups that exist in Tendeki Village, Matuari District, Bitung City, North Sulawesi Province. The width of  pond owned is around 3 ha with an average production of 2 tons per year. The main problem in this group is the difficulty in obtaining superior seeds, expensive feed prices and often the fish that are kept stricken with disease, resulting in less production and even crop failure. Alternative solutions to problems in partner problems are accompanied by two approaches, namely the classical and individual approaches. The classical approach is carried out when delivering the material. An individual approach is taken at the time of practice. Lectures in class in the form of delivery of how to make tilapia seed with sex reversal methods for the maintenance of monosex, making low-quality quality feed made from local raw materials and producing maggot as natural food, as well as how to increase fish immunity by giving immunostimulants to fish feed. Demonstration and practice with techniques for making cheap feed ingredients made from local raw materials. In order for the fish cultivation activities carried out by the partners according to the activity plan, monitoring and assistance will be carried out after the lecture and practice activities. The results obtained showed the group are able to cultivate fish with monosex system, produce feed using local raw materials, maggot cultivation as a natural feed, and can treat fish diseases using mmunostimulant.

Abstract

The objective of research was to determine the concentration of honey in sperm dilution  for improving hatching rate of egg and survival of nile tilapia larvae (Oreochromis niloticus).The number of fish used was five pairs broodstock. Dilution substance was NaCl and honey.  Observations were conducted on spermatozoa motility, fertility and egg hatching rate. Experimental design used was complete randomized design. Sperm dilution substance was prepare by disolving honey  (0 mL; 0,60 mL; 0,65 mL dan 0,70 mL) in 100 mL; 99,40 mL; 99,35 mL and  99,30 mL NaCl respectively.  Each dilution was homogenized using aerator for 15 minutes. Fertilization was done 12 hours after ovulation.  Egg hatching rate was observed after ovulation. Research results showed the use of honey had significant effet on egg hatching rate, but not on larval survival.  Treatment D (0,70 mL honey in 99,30 mL NaCl) had the highest hatching rate (77.33%). Dilution ratio 1:60 was the best indicated by spermatozoa motility 96.66%, fertility 71.65, hatching rate 70% and larval survival 81.67%   Keywords : honey, egg hatching rate, larval survival, Oroechromnis niloticus

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
