A study was conducted to determine the possibility of cashew (Anacardium occidentale) cloning by air-layering and influence of IBA (indol-butyric acid) on this process. It was adopted a completely randomized design with 4 treatments, 10 air layers each and 4 replications, reaching 160 air layers. The IBA levels on the treatments were, as follow: 0, 1000, 3000 and 5000 mg.kg-1. It was evaluated: survival, callus and rooting percentage, average number and length of roots. The highest survival rate (67.5%) was registered with no growth regulator and IBA at 1000 mg.kg-1, while the best rooting percentage (82%) referred to 1000 mg.kg-1. In spite of average number and length of roots, the highest results were observed with IBA at 5000 mg.kg-1. IBA concentrations had no influence on cashew air-layering formation.

The aim of this study was to determine the growth and survival rate of Ctenopoma fish seeds. This study used a completely randomized design with 3 treatments and 3 replications. The treatment in this study was a different feeding rate using natural feed of Tubifex sp  namely A (8%), B (10%), and C (12%) ). The test fish used was Ctenopoma fish seeds with an initial length of 2.40 ± 0.10 cm and an initial weight of 0.32 ± 0.05 g. Fish seeds are cultivated  for 28 days with feeding frequency twice a day. The results of research showed that the use of different feeding rate had an significantly different (P<0.05) on the specific growth  rate and absolute length growth with the best results in the treatment C. The survival rate was not significantly different between treatments (P>0.05). Key Words: Ctenopoma, feeding rate, growth, survival rate

This study aimed to determine the effect of ovaprim hormone, aromatase inhibitor and pituitary on the quality of the catfish eggs (Clarias gariepinus). Experimental Design used was Completely Randomized Design (CRD) with four treatments, each with three replications. Treatment A: ovaprim; treatment B: Aromatase inhibitors, treatment C: hypophysis and treatment D: Control. The results showed that the difference in treatment gave highly significant effect on fertilization and hatching eggs but no significant effect on the survival rate of larvae. Aromatase inhibitor hormone was the best because it provided highly significant effect on fertilization (92.66%), hatchability of eggs (95%), and surviva rate (81.33%) of fish larvae.   Keywords : Clarias gariepinus.

The semah fish (Tor douronensis) is an Indonesian endemic fish that has a long growth, which takes 4 years to grow from larvae to broodstock. This study aims know of Daphnia sp. pelet fed with effective doses to increase the growth of semah’s fish larvae. The study was conducted from March 25 to April 13, 2020 at the Instalasi Riset Plasma Nutfah, Cijeruk, Bogor, West Java. The experimental design used completely randomized design (CRD) 4 treatments and 3 replications, namely treatment A (Daphnia sp.+pelet feed 0 gr/ L), treatment B (Daphnia sp.+ pelet feed 1 gr / L), treatment C (Daphnia sp. + pelet feed 2 gr / L), treatment D (Daphnia sp. + pelet feed 3 gr / L). The larvae of 9 days in age were randomly stocked into 12 aquariums measuring 60x30x35 cm with a density of 50 fish/aquarium and fed in the form of Daphnia sp. enriched pelet feed according to the treatment of 50 ind/larvae by giving 3 times a day which is maintained for 20 days. The test parameters measured are absolute growth in length and weight, survival rate, and water quality. Based on the results of statistical analysis (Anova), the results showed that the treatment D gave the highest influence on the growth of semah’s fish larvae (P <0.05) with an absolute weight growth value of 85,3 mg, absolute length growth of 10.6 mm, and survival rate 99.33%.

Mortality of perinatal lambs and low weight at weaning cause huge liabilities to farmers. Current study describes maternal-filial behavior and evaluates the use of maternal behavior score (MBS) to estimate the behavior of ewes and lambs soon after birth, and correlate it with lamb mortality and performance during lactation. Thirty-seven Corriedale ewes were used in a completely randomized design. MBS was assessed up to 24 hours after birth, taking into consideration the distance of the ewe from the lamb at the approach of a person. Maternal behavior, placental weight, weight gain of the lambs until weaning and their survival rate were also evaluated until two hours after lambing. More than 90% of the ewes had adequate maternal behavior, with parental care, even though ewes were very sensitive to the presence of people. There was no significant correlation between MBS and maternal behavior, lamb mortality rate and live weight gain. Under these conditions, MBS was not a useful tool to estimate maternal behavior and performance of lambs.

ABSTRACT According to Indonesian Standard Quality, the optimal seed production of orange spotted grouper (Epinephelus coioides) has been unsuccessful due to the problems occurred during larval rearing period. Efforts on mass rearing of larvae has been carried out in this study to optimize the natural feeding (rotifer). The purpose of this research was to obtain the information about an appropriate duration time for natural feeding (rotifer) to produce higher survival rate. The treatment for providing rotifers on larvae (days after hatching/DAH) i.e., (A) 20 days, (B) 25 days, (C) 30 days, and (D) 35 days. Rotifers were enriched with DHA Selco. Experiment used fiber tanks with 1 m3 capacity with a completely randomized design (CRD) and three replicates. The larvae was reared to achieve the juvenile phase (D-45). The best results from 1 m3 tanks were then reared using concrete tanks of 6 m3 and 10 m3 capacities. The results showed that feeding of rotifers up to 25 DAH larvae on fiber tanks (1 m3) produced the hughest survival rate (7.63 %). Meanwhile, the mass reared in 6 m3 and 10 m3 concrete tanks produced  survival rate of 4.9±3,54% and 8.8±2.26%, respectively. The homogenous size was relatively high (80%) and the seed abnormality was relatively low (0.4%).   Keywords: rotifers, feeding time, Orange Spotted  grouper larvae, Epinephelus coioides

This research was carried out on March to August, 2018, and the experiment on April to June, 2018 at the Fishery Laboratory, Djuanda University Bogor. The objective of research is to know and analyze the survival rate and feed conversion ratio of Giant Gouramy that cultured on biofloc media and different protein levels. The experimental design that used is completely randomized design   with 2 treatments   and 6 replications.  The treatments are  treatment A (feeding of protein level  of 17% + mollase addition  with C,/N  ratio 12) and treatment B (feeding of protein  level  of  30%  without  mollase)  Fish that used is Giant Gouramy fry with length 5-7 cm that maintained cylinder container of diameter 1 m and height 1 m. The results of research that the artificial feeding of protein level of 17% + mollase addition with C/N ratio 12 gives the survival rate which is better, but the feed conversion ratio is bad. The average of the highest survival rate of Giant Gouramy is 89% (treatment A) and the low feed conversion ratio is 1.6 (treatment B). Water  quality during the research are temperature  of  23,6-30,0 °C, dissolved oxygen of 6.4- 8.8 mg/l and  pH of 6,3-8,8.Key words: Giant Gouramy, biofloc, feed conversion ratio, protein level.

The aim of this research is determine of the optimal stocking density for survival rate and growth of tilapia in round container with water current combined with venturi aeration system. Place of research in the Aquaculture Laboratory, Building 4 Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. The research method used is experimentally with using the Completely Randomized Design (CRD) method which consists of three treatments, there are 15 fish, 22 fish, 30 fish, with five replications. Using water of 15 L per container. The fish used are 3-5 cm tilapia fingerlings. Fish were maintained for 40 days. The feed given is 5% from biomass which is adjusted every 10 days. The parameters observed were survival rate (SR) and observed everyday, daily grow rate (DGR), feed conversion ratio (FCR) and feed efficiency were observed every 10 days. The result was significantly different from the analysis of variance (ANOVA) with the F test at 95% confidence intervals and then using Duncan test to compare the rates between treatments. The results showed that the best treatment was stocking density of 15 fish / 15 L in round container with current combined with venturi aeration system with survival rate of 78.67 ±10.95%, daily grow rate of 3.68 ± 0.12%, feed conversion ratio of 1.19 ± 0.13 and feed efficiency of 85.01 ± 8.97%.
