    This research aims to determine the method of adding potassium diformate to commercial feed to increase survival and growth in gourami juvenile. The method used in this research is an experimental method using a Completely Randomized Design (CRD), consists of four treatments and four replications. The treatments used are (A) Without giving Potassium diformate (control), (B) giving potassium diformate by 0.3%, (C) giving potassium diformate by 0.5% and (D) giving potassium diformate by 0.8%. The test fish used was 300 giant gourami with a length of 4-6 cm. The containers used in this research were aquariums with a size of 40 × 30 × 40 cm3 that reared in 16 aquariums. The density of giant gourami fingerlings during the research was 10 fish per aquarium. The rearing period was 40 days. The feed given was 3% of body mass. Water quality parameters (temperature, pH and dissolved oxygen) were observed every 10 days. Other parameters are the daily growth rate, feed efficiency, the survival rate and the acidity of intestinal and stomach which were observed every 10 days. The results showed that the addition of potassium diformate by 0.3% gives the best results of daily growth rate of 1.31%, feeding efficiency of 37.18%, survival rate of 100% and decreased acidity in the intestine and stomach which helps in the process of protein absorption.

    Opis:
    The research was conducted at the Aquaculture Laboratory of the Faculty of Fisheries and Marine Science, Universitas Padjadjaran, Jatinangor. The purpose of this research is to determine the optimum temperature for the maintenance of Common carp strain Majalaya fingerlings based on resistance to temperature stress that is known through their blood profile and survival rate. Common carp strain Majalaya fingerlings originating from Ciparay, West Java. Total body length is 8-12 cm with a minimum weight of 10 g. The method used is experimental with a completely randomized design (CRD) consisting of three treatments and five replications. The fish are kept at 24 ºC (control without heater), 29 ºC and 34 ºC. Each experimental unit contains 10 fishes. The results obtained by the survival rate (SR) of Common carp strain Majalaya which were maintained at a treatment temperature of 24 ºC by 100%, the 29 ºC by 70%, the 34 ºC by only 42% remained on the 21st day. The number of erythrocytes of common carp strain Majalaya fingerlings before the treatment temperature was 2.77 × 106 cells/mm3. The average number of erythrocytes of the 24ºC treatment from 7th, 14th and 21st day were 2.82, 2.82 and 2.81 × 106 cells/mm3; the 29 ºC were 2.93, 2.68 and 2.42 × 106 cells/mm3; the 34 ºC were 3.08, 2.52 and 1.99 × 106 cells/mm3. While the number of leukocytes of common carp strain Majalaya fingerlings before the treatment temperature was 13.61 × 104 cells/mm3. The average number of leukocytes of the 24 ºC treatment from 7th, 14th and 21st day were 13.73, 13.71 and 13.88 × 104 cells/mm3; the 29 ºC were 18.40, 16.46 and 15.76 × 104 cells/mm3; the 34 ºC were 20.78, 18.46 and 16.81 × 104 cells/mm3.
