Abstract

Desa Pandau Jaya telah memiliki unit Pembenihan Ikan Alaskobar Farm yang bergerak di bidang pembenihan ikan lele. Unit pembenihan ikan Alaskobar menerapkan pemijahan alami ikan lele sangkuriang untuk memperoleh benih. Persoalan yang dihadapi oleh unit usaha Alaskobar Farm ini adalah kurangnya jumlah produksi benih yang dhasilkan, sehingga pendapatan dari hasil usaha budidaya masih minim. Tujuan kegiatan pengabdian kepada masyarakat yang dilakukan adalah 1) Memberikan ilmu dan teknologi tentang pemijahan semi buatan dan pemijahan buatan pada unit pembenihan ikan Alaskobar Farm Desa Pandau Jaya untuk meningkatkan benih ikan lele yang dihasilkan. 2) Meningkatkan penghasilan anggota unit pembenihan ikan Alaskobar Farm dan membuka lapangan kerja 3) Terciptanya agen informasi dan keterampilan tentang pembenihan ikan lele dengan teknik pemijahan semi buatan dan pemijahan buatan di Desa Pandau Jaya sehingga dapat menyebarluaskan kepada masyarakat lain. Anggota Unit Pembenihan Ikan Alaskobar Farm memiliki antusias yang tinggi terhadap teknologi pembenihan secara buatan yang diberikan. Hal ini terlihat dari hasil evaluasi perubahan pengetahuan dimana rata-rata peserta dapat meyerap materi yang diberikan dengan predikat terbanyak sangat baik (nilai A). Hasil evaluasi keterampilan yang dilakukan terhadap Unit Pembenihan Ikan Alaskobar Farm tentang teknologi pembenihan ikan lele melalui pemijahan buatan menunjukkan bahwa peserta kegiatan telah dapat mempraktekkan langsung.

Abstract

ABSTRACT The effect of three protein levels of commercial diet on the growth performance, gonad maturation and fecundity of first maturity of Indonesian leaffish (Pritolepis grooti) was conducted in 54 liters recirculation aquaria system for 10 months rearing period. Eight-week-old artificial spawned  Indonesian  leaffish katung (Pristolepis grooti Bleeker)) fry with an average weight (SD) of 0.560(0.116) g were fed  5% BW three times a day with commercial diets 18, 28 and 38% Protein.  Fish fed on 38%  protein diet showed better growth and feed conversion ratio than those fed on 28 and 18% diets. Males matured earlier than females: the firstmature males were recorded when they were 5 months old, whereas the females matured after 6 month rearing period. The mean percentage of mature female fish rose with increasing feed protein level. It was also found that the percentage of mature fish rose with the increasing fish age and size. More than 70% males matured at the age of 6 months in all diet. After 10 months rearing period, the percentage of matured female fed on 38% protein was 100% while those fed on 16% protein was 25%. Smallest size at spawning of males and females was 8.5 cm (23 g) and 13 cm (65 g), respectively, and dietary protein levels influenced the size of fish at first maturity. It was found that  the protein level significantly effected the gonado somatic index (GSI). Fecundity increased with increasing dietary protein level. The relative fecundity (eggs /g or cm female) was higher at the higher  dietary protein level.   Keywords : Dietary Protein; Growth; Gonad Maturation; Fecundity; Indonesian leaffish Pristolepis grooti

Abstract

ABSTRACT The Indonesian Leaffish,  Pristolepis grooti   is one of  endangered  species found in  some river   system in Indonesia. The demanded and good culture candidate species  for which  the development of larval raring techniques are needed for large scale. A study was conducted to assess the effects  of different type of feeds   on growth and survival rate of the larva for  35 days rearing period. The experiment was designed on completely randomized design (CRD) with 4 treatments, each with 3 replications. Four different feeds were tested, viz. AR (Artemia nauplii), TB  (tubificid worms),  WF (Water Flea, Daphnia and Moina) and BE (Boiled chicken egg yolk). Induced bred larvae (10-day old) were reared in 20 liters glass aquarium with a recirculation water system  During the experimental period the larvae were fed to satiation three times a day.  The water quality variables such as temperature, dissolved oxygen (DO), pH, free ammonia, were found within acceptable limit of larval rearing. The larvae fed tubificid worms had significantly highest (P<0.05) growth (percent length gain (423.3±37.3), percent weight gain (13905.5±567.6), specific growth rate (14.1±0.1) and survival (63.3±16.1) followed by Artemia nauplii and  water Flea  and  boiled chickedn egg yolk. Therefore, tubificid worms may be suggested for feeding Indonesian leaffish larvae up to stockable size. Keywords: Pristolepis grootii, feed type, growth and survival, larval rearing
