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

Optimum Salinity

GIMacro II prawn larvae is able to grow well at a salinity of 8-15 ppt. This condition can be improved by improving the methods of adaptation to changes in salinity prawn larvae production activities, by determining the pattern of changes in salinity are right. Salinity media through osmotic pressure affect the physiological activity, where the cells in body organs prawns should be in liquid media with ionic composition and concentration of the same with the environment. Having obtained the optimum salinity on larval rearing prawns GIMacro II in different salinity media is expected to produce a population of prawns GIMacro II with superior durability specific to environmental conditions, which can then be directed to improve the utilization of marine resources to the salinity of the best. This research aims were to study the growth and survival of larvae prawns GIMacro II reared on media of different salinities. The study used completely randomized design with three treatments and three replications. The treatments were larval rearing prawns GIMacro II at different salinities (10 ppt, 12 ppt, and 14 ppt). The results showed that the culture of prawn larvae GIMacro II at different salinity affect significantly on growth and survival of larvae prawns GIMacro II.  The highest development of GIMacro II prawn larvae obtained from 12 ppt salinity treatment (7.13 ± 0.03%) and the highest survival rate was obtained also from 12 ppt salinity treatment (67.67 ± 4.51%)

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.
