This study investigated the use of a combined formula of artificial feed and fresh marine algae Gracilaria sp in a submerged cage culture system and its effect on Haliotis squamata relative growth and survival rates. The experiment was performed in Lae-Lae Island, Makassar from May to October 2016. The sample Abalone juvenile larvae were 1.5 cm in size and stocked at a density of 30 pcs/cage. The cage size was 30 cm x 15 cm x 7 cm and equipped with a 2-inch Paralone pipe. This experiment employed a completely random design (CRD) with 3 treatments and 3 replicates. The applied treatment included the combination of artificial feed and fresh marine algae Gracilaria sp. Each treatment included: A.  25% artificial feed + 75% fresh marine algae, B. 50% artificial feed + 50% fresh marine algae, C. 75% artificial feed + 25% fresh marine algae, and was given at the proportion of 20% of the abalone's weight. The results of the study indicated that the use of a combined artificial feed with fresh marine algae (Gracilaria sp.) had no significant effect on relative growth and survival rates of Haliotis squamata. Although feed treatment did not significantly affect the relative growth and survival rate, descriptively, treatment A contributed to the most optimal relative growth and the survival rate compared to treatments B and C.

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.

No well-defined changes in growth and survival rates of native brook trout (Salvelinus fontinalis) were detected during a 13-yr period when non-trout species were removed from a small Adirondack Mountain stream using fixed traps located throughout the system. The catch of non-trout species was about 124,000 weighing 2000 kg, and of trout, 13,000, weighing 500 kg. Slow growth characterized the population through this time, with mean lengths of 13.2, 17.3, and 21.3 cm at ages I+, II+, and III+, respectively. The weighted annual survival rate for ages II–V was 18%, with most deaths due to natural causes. The most striking observation was virtual cessation of movement of both trout and non-trout species after 7 yr, suggesting that the removal program had an effect on population behavior, even if it was not reflected in an improvement in trout growth.

This research aimed to determine the optimal dosage of potassium diformate addition to commercial feed in order to increase the growth and survival rate of common carp seeds. The method used in this research was experimental in a completely randomized design (CRD) consisting of five treatments and four replications. The treatments used were A (control), B with addition of potassium diformate (0.2%), C (0.3%), D (0.4%), and E (0.5%). For test fish, there were 200 of Common carp seeds with a size of 2-3 cm. The media used was 20 aquariums with a size of 40x30x40 cm3 and a stocking density of 10 individuals/aquarium. The rearing period was 35 days and the amount of feed given was 3% of the fish body weight. The parameters observed included water quality (temperature, pH, and dissolved oxygen) which were observed every 7 days for 35 days. Other parameters  monitored were daily growth rate, survival rate, feed efficiency, and the acidity level of the intestine. The results showed that 0.3% addition of potassium diformate gave the best results with a daily growth rate value of 3.21%, highest survival of 98%, efficiency of feed utilization of 64.83%, and a decrease in intestinal pH which helped the process of protein absorption in the fish body. In conclution, the addition of potassium diformate has good effect on growth and survival rates of common carp.

Abstract The aim of the study was to determine the influence of the size and form of Artemia sp. feed on the rearing indices of Atlantic sturgeon larvae. In the experiment, the nauplius sizes used were 480 µm (group AD), 430 µm (group AM), and 430 µm frozen nauplii (group AI). After three weeks of rearing, the sturgeon from group AD had the highest mean body weight of 0.131 g that was statistically significantly different from groups AM (0.071 g) and AI (0.033 g). The longest total length was noted in group AD (2.8 cm) and was statistically different from the others (P ≤ 0.05). Specific growth rate in groups AD and AM was 14.7 and 11.8% d−1, respectively, and these values differed statistically from those in group AI at 7.8% d−1. The highest survival rate was recorded in group AD at 60.6%, while the lowest was noted in group AI at 15.6%, and the differences between these two groups were statistically significant. The results of the experiment indicated that a feed of live 480 µm Artemia sp. nauplius significantly accelerated the growth rates and increased the survival rates of Atlantic sturgeon larvae.

The aim of this study was to examine the effectiveness of the commercial bacterial probiotic addition in feed on growth and survival rate of common carp. This research was conducted from July to September 2018. This study used a completely randomized design (CRD) with four treatments and three replications. The initial body length of juveniles was 5-6 cm with density 1 juvenile/litersfor 42 days. In this research, we used different dosages of commercial probiotics 0, 5, 10 and 15 ml/kg. The results showed that the administration of those probiotics in the feed had a significant effect on the relative growth rate, survival rate, efficiency of feed utilization, and protein efficiency ratio on carp juvenile. Administration of probiotics at 15 ml/kg is the best treatment for a relative growth rate 2.96%, survival rate 100%, efficiency of food utilization 72.07%, and protein efficiency ratio 12.19%. In conclusions, probiotics mixed in feed are able to increase the digestibility of feed so that it supports the growth and survival rate of common carp.
