Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi jenis pakan dan hormon estradiol_17β terhadap lama waktu matang, fertilisasi, daya tetas dan sintasan larva ikan lele dumbo (Clarias gariepinus). Metode yang digunakan pada penelitian ini adalah model eksperimental dengan menggunakan Rancangan Acak Lengkap (RAL) dengan 2 faktor perlakuan yang dikombinasikan, dimana faktor pakan terdiri dari 3 jenis pakan yaitu pakan Profish, pakan KRA dan Pakan Profish + pakan KRA. Sedangkan faktor hormon estradiol_17β terdiri dari 3 dosis hormon estradiol_17β yaitu dosis hormon estradiol_17β 0, 250 dan 500 μg/kg berat tubuh ikan, sehingga terdapat 9 kombinasi perlakuan dan masing masing perlakuan diulang 3 kali. Jumlah keseluruhan satuan percobaan adalah 27 satuan percobaan. Penelitian ini dilaksanakan di Balai Budidaya Air Tawar Tatelu, Penelitian ini menggunakan induk lele dumbo betina dengan berat 600 – 700 g/kg sebanyak 27 ekor. Penyuntikan hormon estradiol_17β pada induk ikan dengan perlakuan perbedaan dosis hormon estradiol_17β sesuai dengan disis yang telah ditentukan. induk ikan dipelihara dalam 9 bak beton berukuran 3 x 1,5 x 1,5 meter , masing-masing bak diisi 3 ekor ikan dan diberi makan sesuai dengan jenis pakan perlakuan. Setiap 2 minggu dicek kematangan gonadnya. Lama waktu matang dihitung dari penyuntikan sampai ikan matang gonad. Setelah ikan matang gonad dilakukan pemijahan buatan dengan menyuntikan ovaprim, kemudian induk ikan lele distripping telurnya dan dicampur dengan sperma yang telah disiapkan dari ikan jantan. Selanjutnya pembuahan diamati setelah 6 jam setelah sperma dan telur dicampur. Penetasan dilakukan dengan mengambil 200 telur yang telah berbuah dan di inkubasi selama 2 hari. Telur yang menetas dihitung. Larva hasil penetasan diambil 100 ekor dari masing masing perlakuan. Larva tersebut dipelihara di loyang selama 14 hari dan diberi makan. Larva yang mati dihitung. Data hasil penelitian dianalisis dengan JMP (SAS Institute). Data yang dianalisis adalah data lama waktu matang gonad (hari), pembuahan telur (%) , daya tetas telur (%), dan sintasan hidup larva. Dari hasil yang diperoleh adalah : Perlakuan yang terbaik adalah pemberian jenis pakan KRA dan penyuntikan hormon estradiol_17β dengan dosis 250 μg/kg berat tubuh ikan dengan hasil lama waktu matang gonad 21,67 hari, pembuahan telur 92%, daya tetas telur 87,33% dan sintasan larva 91,67%. Dari penelitian ini disarankan perlu dilakukan penelitian lanjutan dengan melihat hal yang lebih spesifik dan menganalisis mengenai kebutuhan asam amino serta asam lemak esensial serta kadar estradiol_17β dalam darah bagi suksesnya reproduksi ikan lele dumbo.Kata Kunci : Kualitas telur, Clarias gariepinus, Profish, pakan KRA, estradiol_17β

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.
