Abstract

Tiger snail (Babylonia spirata L) is one of molllucs family which has a good economic value both for local and international market. This study was aimed to find out the effects of different stocking densities on the specific growth rate and survival rate of tiger snail cultured in an abandon brackish water pond. A completely randomized design was applied in this research. The treatments were A (18 tiger snail/0,15m2), B (22 tiger snail/0,15m2), C (26 tiger snail/0,15m2), D (30 tiger snail/0,15m2), E (34 tiger snail/0,15m2).  Each treatment was repicated three times.  Plastic baskets at the size of 0.15 were used as a cage for holding system. Tiger snail at initial average body weight of  8 gram approximately was used as tested animal. The study was carried out at an abandon brackish water pond Desa Tapak Kecamatan Semarang Barat, Central java Province from May – July 2007. The results show that different stocking densities affected the specific growth rate and food conversion ratio of tiger snail significantly.  Stocking density of 18 snail/0.15 m2 gave the highest specific growth rate (2.07%/day) and food conversion ratio of 1,747.

Abstract

This research aims to study the effect of cultivation media with the salinity differences on the feed usage, growth, osmotic work (TKO) and survival rate of Spotted Babylon (Babylonia spirata L.) and to find the best cultivation media with the salinity differences on the feed usage, growth, osmotic work (TKO) and survival rate of Spotted Babylon (B. spirata L.). The animals used in this study were obtained from Jepara water area with the average weight of 8,37±0,032 g/. There were 81 animals and raised in 56 days. The natural feed to give was Juwi fish with the amount of 5% of their body weight per day. The research method used in this study was a laboratory experiment with completely randomized design. The treatment use was the salinity differences of the cultivation media with salinity rate of A (27 ppt), B (31 ppt) and C (35 ppt). The results show that the salinity differences of the cultivation media significantly affected (P<0.01) on the feed usage, growth, osmotic performance, but insignificantly affected on the survival rate of Spotted Babylon (B. spirata L.) The cultivation media with the salinity rate of 31 ppt was the best salinity for the feed usage, growth, and osmotic performance of Spotted Babylon (B. spirata L.)Keywords: Spotted Babylon (Babylonia spirata L.), feed usage, salinity, domestication.

Abstract

The aimed of this research to effect probiotics influented on the growth, survival rates, production, productivity and FCR and water quality condition of Pacific white shrimp L. vannamei in pond under semi intensif system. Six of pond compartments each sized 2,000 m2 were stocked with PL-12 at the density of 15 fries/m2. Two treatmens of probiotics application in pond were tested, there were A). 0 mg/L probiotic and B).1.5 mg/L fermentation of probiotic. Each treatment was done in three replicated. On treatment probiotic applied weekly to the ponds started on the first week before shrimp stocking until harvested, while in treatment B probiotic application was mixedwith feed pelled then it was given to the cultured shrimp in the ponds. Result of the research showed that final shrimp body weight in treatment B tend to be higher compared to the treatment A. Absolut shrimp growth-rate in treatment B: 20.727 ± 0.042 g and treatment A :15.7 ± 0.016 g, Shrimp survival rate treatment A 0.432±0.0003 and treatment B : 0.79±0.0145. Production-rate of shrimp in treatment A: 203.627±0.083 kg/2000 m2 and treatment B : 504.489 kg/200 m2. Productivity of shrimp in treatment A : 0.1 kg/m2/period of plants dan perlakuan B: 0.25 kg/m2/period of plants. FCR of shrimp in treatment A 1.79±0.005 and treatment B : 1.42±0.003. Probiotics used in treatment B resulted in the enchancement of water quality condition (total organic matter, nitrat) compared to the treatment A ( 0 probiotics). This condition presumably resulted the highest shrimp production in treatment A.Keywords : production, Pacific white shrimp, probiotics.

Abstract

ABSTRAKKualitas pakan yang baik selain dari kandungan protein, juga berasal dari kandungan mineral yang terdapat di dalamnya. Penambahan madu dalam pakan buatan mampu memberikan kadar mineral yang dibutuhkan tubuh untuk pertumbuhan. Madu mengandung mineral-mineral yang berfungsi untuk pembentukan sel, pengatur kadar air dalam tubuh dan mengandung antioksidan yang dapat berfungsi untuk ketahanan tubuh. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan madu pada pakan buatan terhadap laju pertumbuhan relatif, efisiensi pemanfaatan pakan dan kelulushidupan ikan bandeng (Chanos chanos). Ikan uji yang digunakan dalam penelitian ini adalah ikan bandeng (C. chanos) ukuran nener dengan rata-rata bobot awal sebesar 0.8 – 1.2g dengan jumlah padat tebar 25 ekor/wadah. Frekuensi pemberian pakan dilakukan 3 kali sehari pada pukul 07.00 WIB, 12.00 WIB dan 17.00 WIB sebesar 5% dari bobot biomassa. Penelitian ini dilakukan dengan metode eksperimental menggunakan rancangan acak lengkap (RAL), 4 perlakuan dan 3 kali pengulangan. Perlakuan dalam penelitian ini adalah penambahan madu dengan dosis yang berbeda pada pakan buatan, antara lain: A (0 ml/kg pakan); B (125 ml/kg pakan); C (250 ml/kg pakan) dan D (375 ml/kg pakan). Hasil penelitian menunjukkan bahwa penambahan madu pada pakan buatan memberikan pengaruh nyata (P<0,05) terhadap pertumbuhan bobot mutlak (W), laju pertumbuhan relatif (RGR), efisiensi pemanfaatan pakan (EPP) dan protein efesiensi rasio (PER) serta tidak berpengaruh nyata (P>0,05) terhadap Survival Rate (SR). Perlakuan D (375ml/kg pakan) merupakan perlakuan terbaik yang memberikan nilai tertinggi pada W (249,53±2,75g); RGR (24,55±0,17%/hari); EPP (47,36±0,50%), dan PER (1,81±0,08%). Kualitas air pada media pemeliharaan yang meliputi suhu, DO, pH, amonia dan salinitas tergolong pada kisaran yang sesuai untuk budidaya ikan bandeng (C. chanos). Kata kunci:Pakan; Madu; Ikan Bandeng; Dosis ABSTRACTThe quality of the feed is good aside from the content of protein as well as from mineral contained therein. Addition of honey in artificial fish feed could gave some minerals which needed for growing up. Honey contains minerals that served for the establishment of a regulator, cell water content in the body and contains antioxidants that could served for the resilience of the body. This research aims to know the effect of the addition of honey in the feeding -made against relative growth rate, efficiency of feed utilization and the survival rate of milkfish (Chanos chanos). The fish used in this research is the milkfish (C. chanos) in size with an average weight of 0.8 – 1.2 g to the amount of dense stocking 25-ind /cages. Frequency of feeding was done in 3 times a day at 7:00 PM GMT, 12:00 PM GMT and 17:00 PM GMT amounting to 5% of the weight of biomass. This research was conducted with the experimental method using random design complete (RAL), with the 4 treatments and repetition as much as 3 times. The treatments in this study is the addition of honey with different doses in artificial feed such as  A (0 ml/kg of feed); B (125 ml/kg of feed); C (250 ml/kg of feed) and D (375 ml/kg of feed). The results showed that the addition of honey in artificial feed has significant (P < 0.05) in absolutally weight (W), relative growth rate (RGR), efficiency of feed utilization (EPP) and protein effeciency ratio (PER) and has no significant (P > 0.05) for survival rate (SR).  The treatment D is the best once which has gave the highest value on the W (249,53 ± 2,75 g); RGR (24,55 ± 0,17 %/day); EPP (47,36±0,50%), and PER (1.81±0.08%). Water quality maintenance of media such as temperature, DO, pH, salinity and ammonia have in range that is suitable for the cultivation of milkfish (C. chanos). Keywords: Feed, Honey, Milkfish, Doses
