ABSTRACTThe research was conducted in Juli 2019 – Agustus 2019 at BBPBAP Jepara, the aim to determine the effect and get the best dose of recombinant growth hormone grouper fish (rElGH) for growth and survival of white shrimp (Penaeus merguiensis). This research was conducted using experimental methods with completely randomized design (CRD) with one factor, five levels of treatment and three replications. The treatment was used sink dose of 0 mg/L, 10 mg / L, 15 mg / L, 20 mg / L, 25 mg / L. White shrimp used was PL10 stadia with an average weight of 0.0017 g. The results showed that the added of rElGH by immersion method significantly affected (P <0.05) the growth of absolute weight, specific growth rate of PL10 white shrimp stage. Addition of recombinant growth hormone at dose of 20 mg / L gave the best results on growth of absolute weight 0.1642 g and specific growth rate of 13.47% and survival rate of 93.3%. Keywords : recombinant rElGH growth hormone, white shrimp, growth.

The purpose of this study was to determine the best dose of carbon source addition of molasses in biofloc system toward growth and survival rate of red tilapia in brackish water media. The method in this study was the experimental method of completely randomized design (CRD) with one factor, four treatments and three replications. P1:  carbon source addition by 50 ml /m3 of molasses dose, P2: carbon source addition by 100 ml /m3, of molasses dose, P3: carbon source addition by 150 ml / m3 of molasses dose, and P4: carbon source addition by 200 ml /m3 of molasses dose. The results showed that the best treatment of carbon source additionwas at the 200 ml/m3 (P4)of molasses dose. The specific growth rate was 4.25%, 132.29% of feed efficiency, feed conversion ratio (FCR)was 0.75, survival rate (SR) was 81.67%, floc volume was 4.61 ml/l. The qater quality parameters consists of temperature was arround 26-310C, DO was 4.13 to 6.83 mg/ l, pH was 7 to 7.6, 16-20 ppt of salinity and ammonia was from 0.0718 to 0.3625 mg/ l. Keywords: Molasses, Biofloc, Red Tilapia (Oreochromis sp)

Abstract

ABSTRACTThe aim of research was to find out the effect of different densities on the growth and survival rate tilapia fish (Oreochromis niloticus) brackish water using a recirculation system. The research was conducted in 35 days observation, started from March to May 2018 at UPT Teluk Papal Village, Bantan districts, Bengkalis regency, Riau Province. The test fish used are red tilapia fishs (Oreochromis niloticus) that  have a measurement of 3 – 5 cm. The method used this research is Completely Randomized Design (CRD), with 5 treatments and 3 replications each. The difference of density of dispersion at each treatment P1, P2, P3, P4 and P5 are 25, 20, 15, 10, dan 5 fishs/10 liters in brackish water with recirculation system. The fish are fed adlibitum at 08.00, 12.00, dan 16.00 WIB. The results showed density did not have effect on survival rate  (P> 0,05), but has an effect on absolute weight growth, length total and daily growth rate (P> 0,05). The value of growth and survival rate is the  best obtained from 5 fishs /10 liter stocking density treatment with an absolute weight of 6.06 grams, an absolute length of 3.71 cm, a specific growth rate of 5.97% and a 100% survival rate. Keywords: Tilapia, density, growth, survival rate, recirculation systems

The purpose of this study is to in vestigatedifferent form of container with recirculation systems. Water treatment from tarpaulin with a capacity of 80 L in air volume. Fish stock was 20 fish/tank. The research method was the experimental method with 4 treatments and 3 replications. Treatments was : P1= Circle Shape, P2 = Square Shape, P3= Leg Length and P4= Triangle Shape. The results of this study can be concluded that the different forms of container are not significant to the growth of red tilapia, but the forms of containers are significantly different for the survival of red tilapia. Growth performance of round shape, square shape, rectangular shape and triangle shape, each of which has given weight growth 9.12 g; 10.04 g; 8.95 g; and 8.49 g, then the growth of a double length of 4.30 cm; 4.56 cm; 4.13 cm; and 4.03 cm, daily growth rate of 4.29%, 4.67%, 4.43% and 4.34, feed feed 82,04%, 91,47%, 83,61% and 79,66%, and the rate of life is 85.00%, 96.66%, 90.00% and 85.00%. The measurement results of water quality are still in the optimal range in the maintenance of red tilapia, namely temperatures of 26-29.3 ° C, pH 6.3-6.8, DO 4.5-6.1 mg / L, and ammonia 0.26- 0.17 mg / L.Keywords : Oreochromis sp, recirculation system, different shape of tank survival rate

Abstract

ABSTRACTThis research was conducted in Agustus to September 2018 in the Aquatic Aquaculture Technology Laboratory of Marine Fishery University of Riau. The aims of this research was to determine the growth and survival rate of Channa striata with different feeds. This research used a size aquarium 40 x 30 x40 cm3 with a waterin hight 10 cm for 12 units. The feed used in the form of Pellet, Earthworms, Blood worm, and Tubifex sp. given with dose of 60% from the body weight of thefish. The method used in this research was the experimental method of Completely Randomized Design (CRD) using one factor with 4 treatments and 3 replications. The best treatment result is feeding with Tubifex sp which can produce absolute weight growth rate (1,48 gram), absolute length growth (3,7 cm), growth of specific length (5,45%) and survival rate (97,22%). Water quality during the research was obtained of pH 6.0-7.0, temperature 26-28 0C, DO 3,9-5,4 mg/L and ammonia 0,01-0,05 mg/L. The result of research with different feeding significantly affected the growth of Channa striata, but did not significantly affect the survival of Channa striata. Giving Tubifex sp. is the best feeding to increase the growth of Channa striata. Keywords : Tubifex sp, Channa striata, Growth and survival rate.
