Abstract

The problem in Mutiara strain of North African catfish Clarias gariepinus culture is that the production of both larvae and seeds is still inhibited by the seasonal reproductive cycle where the catfish only spawn once during the spawning season.  The purposes of this study were to evaluate the effect of administration of oodev and estradiol-17ß on the maturity process and to determine the best doses in accelerating the maturion of female Mutiara strain. This study used a Completely Randomized Design with 5 treatments and 3 individual replications. The treatments were combination between dose Oodev (PMSG and Anti-Dopamine) and dose Estradiol-17ß in feed (both doses in ml/kg feed):A(0+0), B(0.5+0), C(0+0.6), D(0.5+0,6), E(1+1). The results of this study showed that the administration of Oodev and Estradiol-17ß significant affect on gonadal maturity index about 82.21% compared to control and acclerating maturation of female mutiara strain with doses the best is the treatment E (oodev 1 ml/kg feed+estradiol-17ß 1 ml/kg feed).Key words: Clarias gariepinus, dose, estradiol-17ß, maturation, oodev

Abstract

Utilization of ex-sand pit lakes for aquaculture is difficult due to low water quality and high concentrations of iron (Fe). Phytoremediation using aquatic plants has been proven to be effective in reducing Fe in waters. This study aims to determine the growth, feed conversion efficiency and survival rate of tilapia (Oreochromis niloticus) cultured with ex-sand mining water media with phytoremediation treatment. Phytoremediation treatment was carried out by Eichhornnia crassipes, Azolla pinnata, and Salvinia molesta. Fish culture experiments were carried out in plastic tarpaulin tanks for 40 days, with ad satiation feeding, three times a day using the commercial feed. The results showed that phytoremediation with aquatic plants had succeeded in reducing Fe to a level suitable for fish culture. Fish culture experiments showed an absolute length growth rate of 0.09-0.18 cm/day and an absolute weight growth rate of 0.11-0.16 g/day. The feed conversion ratio was 1.18-1.40 and the survival rate was 98.04-99.08%. The survival rate of tilapia is high, the feed conversion ratio is medium and growth is low. The high environmental temperature and the decrease in water quality due to the absence of water changes and aeration are suspected of causing the low growth of fish. Therefore, further research with water change and aeration experiments and the use of other species of fish is needed to follow up the results of this study.

Abstract

The nature of cannibalism in snakehead fish (Channa stiata) causes high mortality in snakehead fish farming. Good and proper management is needed to minimize its cannibalism. The aims of this research were intended to find out the feeding frequency and feeding rate in growth performance and survival rate of snakehead fish seed. This research was conducted with Factorial Completely Randomized Design (FCRD), which consisted of 2 factors, feeding rate and feeding frequency each with triplicates. The treatments of feeding rate were 3%, 5%, and 7% and the treatments of feeding frequency were 3 and 4 times everyday. The used feed is commercial feed PF-800. The result of this research indicated that feeding rate 7% with 4 times feeding frequency each day was the highest absolute weight and length of growth rate than the other treatments. The highest value in survival rate parameter was feeding rate 3% with 3 and 4 times/day. On the other hand, the lowest value in FCR parameter was feeding rate 5% with 3 times feeding frequency each day. Meanwhile, the highest value in protein retention parameter was feeding rate 5% with 3 times/day. The result showed that there was any interaction in absolute weight of growth rate and protein retention. The single factor in form of feeding rate gave significant results of survival value and feed conversion ratio. The result of this research showed that feed management of 7% FR with 4 times/day FF gave the best result in growth, FCR, and protein efficiency of snakehead fish. Although, it has the lowest SR value, but 7% FR with 4 times/day FF can produce the highest biomass of snakehead fish in this study reached 114,45g.

Abstract

The results of spawning in sangkuriang catfish farming do not always go according to the expected results, as many eggs died before hatcing. Therefore, it is necessary to use spawning hormones which can improve egg quality in order to increase profits in cultivation. This research was aimed to determine the difference on success performance of sangkuriang catfish using HCG, Ovaprim, and Spawnprim. This research used a randomized block design (RAK) with 3 treatments i.e P1 (HCG 500 IU/kg), P2 (Ovaprim 0,5 ml/kg), P3 (Spawnprim 0,5 ml/kg) and 3 groups of repetition i.e K1 (spawning group day-1), K2 (spawning group day-2), and K3 (spawning group day-3). The results of this research showed that using Ovaprim hormone had the highest value than other treatments like on latent time 606±17,78 minutes, egg fertilization percentage 75±2,65%, and egg hatching percentage 69,33±5,69%. Then on egg fecundity and egg diameter showed no significant effect with other treatments.

Abstract

Ikan bandeng (Chanos chanos) merupakan salah satu komoditas perairan payau yang potensial untuk dibudidayakan. Penyediaan benih dan pakan yang baik secara kualitas maupun kuantitas sangat diperlukan demi meningkatkan produksi ikan bandeng. Ampas kelapa adalah limbah pertanian yang dapat digunakan sebagai campuran bahan baku pakan ikan melalui proses penepungan. Penggunaan tepung ampas kelapa ini diharapkan dapat mengurangi penggunaan bahan baku pakan impor yang harganya mahal. Penelitian ini bertujuan untuk mengetahui jumlah penambahan ampas kelapa yang optimal pada pakan untuk pertumbuhan ikan bandeng. Penelitian dilaksanakan pada bulan Januari – Maret 2017 bertempat di Desa Purworejo Kecamatan Pasir Sakti Kabupaten Lampung Timur. Penelitian menggunakan 4 perlakuan dengan 3 kali ulanganyaitu Perlakuan A (Pelet komersil), B (Pelet komersil + tepung ampas kelapa 10%), C (Pelet komersil + tepung ampas kelapa 20%) dan D (Pelet komersil + tepung ampas kelapa 30%). Parameter yang diamati yaitu laju pertumbuhan (pertumbuhan mutlak dan harian), efisiensi pakan, identifikasi dan kelimpahan fitoplankton serta parameter pendukung yaitu kualitas air. Hasil penelitianmenunjukkan bahwa pada parameter laju pertumbuhan (pertumbuhan mutlak dan harian) serta efisiensi pakan perlakuan D berbeda nyata dengan perlakuan A, B, dan C. Akan tetapi perlakuan A, B dan C tidak berbeda nyata. Kesimpulan yang didapat bahwa penggunaan tepung ampas kelapa dengan jumlah maksimal 20% tidak memberikan pengaruh terhadap laju pertumbuhan dan efisiensi pakan pada ikan bandeng.

Abstract

Oodev hormone application has been applied to stimulate gonadal maturity so that fish fry could be available outside the spawning season. This research aimed to study the effect of Oodev hormone on the gonadal maturity of asian redtail catfish Hemibagrus nemurus (Valenciennes, 1840). This research method used a completely randomized design (CRD) with 4 doses treatments, i.e 0, 0,25, 0,50, 1,00 ml/kg. A total of 8 fish were used as replications for each treatment. The parameters measured were the gonado somatic index (GSI) and egg diameter. The results showed that the effect of Oodev hormone on GSI and egg diameter was significantly different (P<0.05). A higher Oodev hormone dose caused an increase of GSI and egg diameter size. The recommended Oodev dose for application is 1 ml/kg.
