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

This research intended to evaluate the area suitability of  Scylla spp at Likupang II Village, North Minahasa. The research was done descriptively by observing water quality, area availability. SWOT analysis was used to determine the development strategy.   Data were collected by interview, observation and questionnaire.  Research result showed that the potential of Likupang II Village was suitable for Scylla spp culture.  SWOT analysis showed internal factors affected the development of Scylla spp culture.  The strength were location, water quality, government support; the weakness were seed availability, opportunity, government policy and treating were season and safety.   Keywords : Scylla spp, SWOT analysis, , Likupang II, area suitability

Abstract

Abstract This study aimed to determine the effect of different doses of ovaprim on spawning time, egg hatchability, and survival of  African catfish larvae (Clarias gariepinus). The research was done in the Central Local Fish Seed (BBI) Jayapura, Papua Province. Experimental design used was Randomized Complete Design. The study consisted of four treatments namely 0 ml, 0.3 ml, 0.6 ml and 0.9 ml ovaprim, each with three replications. Data collected were spawning time, egg hatchability, and survival rate of African catfish larvae. The number of containers used was as much as 12 buckets (for spawning, hatching, and observation of survival rate of larvae). The results showed that treatment with different doses of ovaprim hormones provided a significant influence on the latency time of spawning, egg hatchability and survival rate of larval. The dose of 0.3 ml ovaprim caould increase the latency time of spawning, egg hatchability and survival rate of African catfish larvae. The average latency time of hatching was 552 minutes,  spawning and  egg hatchability 84.16% and survival rate of  living larvae was 85.76%. Keywords : African catfish, Ovaprim, spawning time, egg hatchability, survival rate

Abstract

Abstract The purpose of this study was to investigate the effect of vitamin C with different doses of the long time ripe gonads, egg hatchability and larval survival of catfish (Clarias sp). This research used Complete Randomized Design (CRD) with four treatments each with three replications. The treatment in this study were different doses of vitamin C namely 0, 600, 1200 and 1800 mg / kg of feed. Data was analyzed usung analysis of variance and continued with the Smallest Real Difference test.     Parent female catfish  used was 1.5 years age with a weight of 800-900 g. Feed used was  pellets supplemented with vitamin C.  Fish was reared in four tanks measuring 2 x 1 x 1 m and fed every morning and evening ad libitum. The results of the study was the addition of vitamin C in the diet significantly influenced the speed of gonad maturation, egg hatchability and larval survival. Treatment with the addition of 1200 mg / kg of feed was the best treatment with gonadal maturation speed achieved on 39.33 days, the highest egg hatchability 83% and survival of larvae was 7.66 days.   Keywords: Clarias gariepinus, Vitamin C, gonadal development, egg hatchability, larval survival.
