Abstract

The development of vaname shrimp (Litopenaeus vannamei) culture will affect the increasing need of live food organisms for shrimp larvae, especially Artemia sp. In shrimp hatchery, biotechnical constraints of culture of Artemia sp. and dependence on imported cysts is a limiting factor for success. Perhaps, the use of Oithona sp. is an alternative live food for L. vannamei larvae which has the potential to be combined with Artemia sp. The aim of this study was to examine the effect of a combination of live foods, Artemia sp. and Oithona sp. on the survival rate of L. vannamei shrimp larvae and to determine the percentage of live food combinations that provide the best survival rate of L. vannamei shrimp larvae. The method used was an experiment carried out at the Coastal Area Development Laboratory, Jepara. The experimental design used CRD with 5 treatments and 4 replications. Those treatments were a combination of live food, Artemia sp. and Oithona sp. with the percentage ratio of each treatment A. 100%: 0%; B. 75%: 25%; C. 50%: 50%; D. 25%: 75%; and E. 0%: 100%. The results showed that the combination of live foods of Artemia sp. and Oithona sp. had a significant effect (p<.05) on the survival rate of the L. vannamei  shrimp larvae and the percentage of the combination of natural foods, Artemia sp. ranged of 50 -100% and Oithona sp ranged of 0% - 50% had given the survival rates of L. vannamei larvae (N-5/6 to PL-10)  ranged of 41.71-43.00%.

Abstract

The optimum condition of culture media and feed diets which fit the necessities of Oithona similis life (ecophysiological) is very important for it to grow and develop in its maximum. The enrichment of O. similis feed can be done by adding fermented organic feed. Providing organic feed with optimum protein content is necessary to support the growth process and reproduction of O. similis. Osmoregulation process of water organism which is influenced by media salinity is related to bioenergetics process as the effort to use feed energy for the growth. This research aimed to examine the effect of different organic feed protein content and to determine the optimum point which may result in the best growth and egg production of O. similis in the optimum condition of culture media. The study used an experimental method with a completely random design consisting of 4 treatments and 4 repetitions each, i.e. O. similis culture with A. 25%; B. 30%; C. 35%; and D. 40% organic feed protein content. The results showed that the difference of protein content in organic feed affects the growth and production of O. similis eggs. The optimum point of protein content in the fermented organic feed is on protein content B, i.e. 30%, which resulted in the best growth performance (70.44 ± 0.43 ind.mL-1 total density, 0.213 ± 0.001.day-1 population growth rate, and 27.38 ± 0.48 eggs.ind-1 egg production.

Abstract

Pengembangan budidaya ikan lele, Clarias gariepinus sering terjadi kendala dengan biaya pakan yang terlalu tinggi (60-70% dari biaya produksi). Barangkali, penggunaan bahan baku lokal seperti pemanfaatan tepung telur ayam yang nilai nutrisinya tinggi, mudah didapat, dan murah harganya merupakan salah satu solusinya. Tujuan penelitian ini adalah untuk mengkaji dan mengetahui pengaruh penambahan tepung telur ayam afkir dalam pakan buatan yang berprobiotik terhadap efisiensi pemanfaatan pakan, pertumbuhan dan kelulushidupan ikan lele dumbo (C. gariepinus). Penelitian ini menggunakan metode eksperimental dengan rancangan acak lengkap (RAL) yang menggunakan  4 perlakuan dan masing-masing 3 kali kali ulangan. Perlakuan itu adalah pakan yang tanpa menggunakan tepung telur ayam afkir (Perlakuan A), pakan yang menggunakan tepung telur afkir masing-masing sebanyak 15%, 30%, dan 45% sebagai Perlakuan B, C, dan D. Ikan uji  bibit lele dumbo (C. gariepinus) yang ditebar mempunyai bobot rerata 2.04±0.05 g dengan kepadatan 1 ekor/L yang dipelihara selama 42 hari. Variabel data yang diukur meliputi Tingkat Konsumsi Pakan (TKP), Efisiensi Pemanfaatan Pakan (EPP), Feed Convertion Ratio (FCR), Protein Efficiency Ratio (PER), Relative Growth Rate (RGR), dan Survival Rate (SR). Hasil penelitian ditunjukkan bahwa penggunaan tepung telur ayam afkir pada pakan buatan memberikan pengaruh yang nyata (p < 0.05) terhadap TKP, EPP, FCR, PER, dan RGR, tetapi tidak berpengaruh nyata (P≥0,05) terhadap SR. Perlakuan dengan penambahan tepung telur ayam afkir sebanyak 30% (Perlakuan C) memberikan nilai terbaik untuik TKP sebesar 146,87%, EPP sebesar 88,77%, PER sebesar 2,61% dan RGR sebesar 7,65%/hari dari perlakuan lainnya. Monitoring nilai kualitas air pada media pemeliharaan telah menunjukkan bahwa pada kisaran yang layak untuk pemeliharaan ikan uji. Catfish cultivation development, Clarias gariepinus often occur constraints with the high cost of feed  (60-70% of the production cost). Perhaps, the use of local raw materials such as the utilization of rejected chicken egg with high nutritional value, easy to obtain, and cheap price is one of the solution. The purpose of this research was to know the effect of addition of rejected chicken egg  powder inprobiotized artificial feed on the efficiency of feed utilization, growth and survival rate of catfish, C. gariepinus. This study was used an experimental method with completely randomized design (RAL) by using 4 treatments and each of them 3 replications. The treatments were feed without use of rejected chicken egg powder  (Treatment A), feed using 15%, 30%, and 45% of powder  meals of rejected chicken egg  as treatment B, C, and D, respectively. Catfish, C. gariepinus seeds were stocked with a mean weight of 2.04 ± 0.05 g with a density of 1 tail / L and cultured  for 42 days. The data variables measured were  Total of Feed Consumption (TFC), Feed Utilization Efficiency (FUE), Feed Conversion Ratio (FCR), Protein Efficiency Ratio (PER), Relative Growth Rate (RGR), and Survival Rate (SR). The results showed that the use of chicken egg starch in artificial feed gave a real effect (p <0.05) on TFC, FUE, FCR, PER, and RGR, but no significant effect (P≥0,05) on SR. Treatment with the addition of 30% chicken meal (Treatment C) had the best value for TFC at 146.87%, the FUE of 88.77%, the PER of 2.61%  and the RGR of 7.65% / day than of the another treatments. Monitoring of  water quality values on maintenance media has shown that at a reasonable range for the maintenance of catfish culture.
