Abstract

Feed is the main source of nutrients to support vannamei shrimp growth. The high cost of feed in operational costs due to the high raw material price of fish meal, limited availability, while the demand is high. Therefore it is necessary to find alternative materials that are low in price, have a high enough protein content and abundant availability such as golden snail flour. The purpose of this study was to analyze the effect of different proportion of fish meal and mashed snail (Pomacea canaliculata) as the main feedstock for the growth of shrimp vannamei (Litopenaeus vannamei). The experimental design used in this study was Completely Randomized Design (RAL) consisting of 5 treatments, namely A (57.18% use of fish meal in feed), B (42.89% use of fish meal, 14.30% mashed flour), C (28.59% fish meal usage, 28.59% mashed snail), D (Use of 14.30% fish meal, 42.89% mashed snail), and E (Use 57.18% golden snail flours). This study shows that the addition of mashed snail flour in the feed can increase the growth of absolute weight, the daily weight of vannamei shrimp, and can decrease the value of FCR.

Abstract

Eel is one of the fisheries commodity that have not been rearing widelyin Indonesia. Constraint that occured in rearing eel is slow growth. A way to accelerate eel growth isfeeding with enrichment by using an amino acids. An amino acids can be used directly by eel for cell growth and the formation of body tissue. An amino acid that is used from the stingrays are not utilized by people  because it has no economic value to production activities. This research was aimed to study the growth rate of eel whichis fed with enrichment of an amino acids derived from stingray extract. The method in this research used completely randomized design (CRD) with 3 treatments and 3 replications. The measure of eel that usedare 26-28 cm, the average weight is 28 grams and an amino acids dosage that used are 0 ml, 0.5 ml and 1 ml. It use FR 3% which is given at night to support the characteristic of eel that is nocturnal (active at night). The analyze result from the parameters that have been observed, there is not a significant effect (P> 0.05) and the fed with enrichment by using an amino acids with the dosage used hasn't been able to be utilized as fish feed mixture to increase growth rate.

Abstract

Aeromonas salmonicida merupakan bakteri penyebab penyakit furunculosis dan carp erytrodermatitis. Saat ini sudah dikembangkan vaksin inaktif A. salmonicida dengan formalin yang memiliki imunogenisitas yang cukup tinggi. Vaksin inaktif dengan metode lain perlu dilakukan, salah satunya inaktivasi dengan pemanasan (heat killed). Tujuan dari penelitian ini untuk mengetahui imunogenisitas heat killed vaksin A. salmonicida pada ikan mas (Cyprinus carpio). Penelitian telah dilaksanakan pada bulan Oktober sampai Desember 2012, di Laboratorium Budidaya Perikanan, Fakultas Pertanian, Universitas Lampung. Penelitian ini dilakukan dengan membandingkan antara pemberian vaksin dan tanpa pemberian vaksin. Bakteri A. salmonicida diinaktifasi dengan pemanasan pada suhu 100ºC selama 1 jam. Uji viabilitas dilakukan pada media GSP (Glutamat Starch Pseudomonas) untuk memastikan bakteri sudah inaktif. Konsentrasi vaksin diukur dengan spektofotometer ( =625 nm) dan dibandingkan dengan standar Mc Farland. Vaksinasi dilakukan dua tahap secara injeksi intraperitoneal, vaksinasi I dilakukan dengan konsentrasi 107 sel/ikan dengan volume 0,1 ml/ikan. Vaksinasi II dilakukan 8 hari setelahnya dengan konsentrasi yang sama. Pengambilan darah untuk pengamatan hematologi dilakukan sebelum vaksin, 7 hari setelah vaksinasi I, 7 hari setelah vaksinasi II. Ikan yang divaksinasi menunjukan adanya peningkatan imunogenisitas yang ditandai dengan peningkatan nilai titer antibodi, total leukosit, dan korelasi negatif antara total leukosit dengan hematokrit.

Abstract

The feed given to cobia’s juvennile (Rachycentron canadum) still uses expensive factory-made feed to be the basis of this research. This aims of this research to examine the effect of feed formula with different protein levels on optimal growth cobia. This research method  used a completely randomized design (CRD) with three treatments and three replications. The treatment in this study were different protein level commercial feed (as control/46%), and formula feed (protein P1 46% and P2 protein 48%). The parameters tested included absolute weight, daily growth rate, feed conversion ratio, protein retention, and survival rate. The data obtained were analyzed by analysis of variance and continued with the duncan test with a 95% confidence interval. The results showed that the growth of absolute weight and daily growth rates generated from each treatment were significantly different (p <0.05), K (80.30 ± 11.20c g and 1.78 ± 0.25c g/day), P1 (21.87 ± 1.95a g and 0.49 ± 0.05a g/day), P2 (37.43 ± 3.29b g and 0.83 ± 0.07b g/day).
