Plankton as a natural feed is thought to be a factor that affects the growth of hoven’s carp fry. Plankton abundance can be increased by the addition of organic fertilizers containing nutrients (nitrate and phosphate). Nutrients abundance can be increased by addition of fermented banana hump’s This research aimed to determine the use of fermented banana’s hump to increase the availability of natural feed nursery and the growth of hoven’s carp fry. The method of this research used a completely randomized design with four treatments and three replications, i.e: P1 (control), P2 (5,0 ppm), P3 (7,5 ppm), and P4 (10,0 ppm) addition of fermented banana’s hump. The measured parameters were nitrate, phosphate, plankton abundance, growth and water quality. The results showed the dose of addition of banana weed fertilizer had an effect (P< 0.05) on the abundance of natural feed and the growth of hoven’s carp fry. Results of water quality measurement showed the parameters of temperature ranged from 25 to 27 °C, pH ranged from 6,23 to 7,53, DO ranged from 3,40 to 11,36 and ammonia from 0 to 0,001 mg/l. The recomended dosage of fermented banana’s hump was 10 ppm for 1 l of water media.

Leucaena leaves is a potential ingredient for raw material feed of catfish. The aim of this study is to evaluate the effects of dietary fermented leucaena leaf on digestibility and hematological parameters of catfish. Four treatments and 3 replicates, namely: A (reference feed 70% + leucaena leaves meal 30%), B (reference feed 70%+fermented leucaena leaves meal with A. niger 30%), C (reference feed 70%+fermented leucaena leaves meal with R. oligosporus 30%), and feed D (reference feed 70%+fermented leucaena leaves meal with S. cerevisiae 30%) were used in this study. The juvenile catfish (initial weight was 5,45±0,16 g) are randomly distributed into eighteen tanks with 40 fish per aquarium. Each diet is randomly assigned to the triplicate aquarium and fed to fish three times a day up to satiation for 4 weeks. The results showed that fermented leucaena leaves treatments were significantly higher (P<0.05) than that control in final weight and feed conversion rasio. Nutrients digestibility and final weight were significantly highest (P<0.05) in fermented leucaena leaves with A. niger compared to the other treatment. The value of protein digestibility was significantly highest (P<0.05) in fermented leucaena leaves with A. niger (76,04%), followed by fermented leucaena leaves S. cerevisiae with (69,71%), fermented leucaena leaves meal with R. oligosporus (68,24%), and control (65,18). Leucaena leaves had no effect on physiological processes in catfish, as shown by hematological parameter values that were within the normal range.

THE EFFECTS OF AMETHYST Datura metel (LINN, 1753) LEAVES EXTRACT AS AN ANESTHETIC AGENT ON HAEMATOLOGICAL CONDITION OF TILAPIA Oreochromis niloticus (LINN,1758) FRY Revita Syefti Palmi; Indra Gumay Yudha; Wardiyanto Wardiyanto

Anesthetic method is an important component to support the activities of transporting live fish from one place to another for a long period of time. Cost efficiency and effectiveness of anesthetic ingredients that not cause residues in fish are factors to beconsidered as an anesthetic. Aim of this research is to study the effect of subletal concentration of amethyst leaf extract on the hematological conditions of tilapia fry after transporting on wet transportation systems. The research procedure was through the amethyst leaf extract toxicity test series (LC50-96 hours) to determine its sublethal concentration by 20% (0,297 ml/l), 30% (0,445 ml/l) and 40% (0,594 ml/l) of the LC50 value. The measured parameters are clinical symptoms, period of fainting and conscious recovery, hematological analysis, survival rate, and water quality. The results showed the concentration of amethyst leaf extract had an effect (P<0,05) on the period of fainting and the hematological component after transportation simulation. Results of water quality measurement showed the parameters of pH at 6 and ammonia 0,04 mg/l are not at the optimum value when fish transportation occur. The recommended concentration of amethyst leaf extract for use as an anesthetic agent is 0,445 ml/l

THE STIMULATION OF GONAD MATURITY OF ASIAN REDTAIL CATFISH Hemibagrus nemurus (Valenciennes, 1840) THROUGH INDUCTION OF OOCYTE DEVELOPER (Oodev) HORMONE Devika Kharisma Putri; Tarsim Tarsim; Deny Sapto Chondro Utomo; Indra Gumay Yudha

Oodev hormone application has been applied to stimulate gonadal maturity so that fish fry could be available outside the spawning season. This research aimed to study the effect of Oodev hormone on the gonadal maturity of asian redtail catfish Hemibagrus nemurus (Valenciennes, 1840). This research method used a completely randomized design (CRD) with 4 doses treatments, i.e 0, 0,25, 0,50, 1,00 ml/kg. A total of 8 fish were used as replications for each treatment. The parameters measured were the gonado somatic index (GSI) and egg diameter. The results showed that the effect of Oodev hormone on GSI and egg diameter was significantly different (P<0.05). A higher Oodev hormone dose caused an increase of GSI and egg diameter size. The recommended Oodev dose for application is 1 ml/kg.

Avicennia alba is a mangrove plant that often ued by coastal society as a traditional medecine, it is potential to be dveloped as the sources of pharmaceutical. The aim of the research is to examine the effect of Avicennia alba leaves extract various concentrations to Vibrio harveyi infection on vaname shrimp. The addition of the extract is thought to be used as an antibacterial so that it can give effect to the attack of V. harveyi in vaname shrimp. Vaname shrimps (total of 120 shrimps) with a weight of 10±2g/ind were injected intramuscularly with V. harveyi bacteria in 107 CFU/ml density. After the occurrences of clinical symptoms, the shrimps were immersed into A. alba leaves extract with concentration 0 ppm, 150 ppm, 250 ppm, and 350 ppm for 21 days. The results showed that the addition leaves extract can increase shrimp’s survival rate as much as 46.67% and increase the shrimp’s ability to prevent (RPS) V. harveyi infection untill of 70±15%. The mean time of death (MTD) was 106±18.33 hours, it caused there ar active compounds contained such as saponin, tannin, and steroid be suspected antibacterial so that they can protect shrimp from the effect of Vibrio infection damage. Giving a concentration of 250 ppm Avicennia alba leaves extract can treat vaname shrimp which was attacked by V. harveyi better than other treatments.

Eel (Anguilla bicolor) is an Indonesian freshwater commodity that has high economic value but has slow growth. One method to accelerate eel growth is through feeding with the enrichment of essential fatty acids. The aim of this research is to know the increase of growth rate of eel fish fed with the enrichment of essential fatty acids with fish oil and corn oil. The study used 3 treatments and 3 replications ie A (0% corn oil + 0% fish oil), B (1.5% corn oil + 1.5% fish oil), and C (3% corn oil + 3% fish oil). Parameters observed included specific growth rate, total feed consumption, feed efficiency, fat retention, and survival rate. The supporting parameter is water quality. The data obtained were analyzed by analysis of variance and continued by fisher test with 95% confidence interval. The results showed that there was a significant effect (P <0.05) on the growth rate of eel fish fed with the enrichment of essential fatty acids with fish oil and corn oil. Treatment C (3% corn oil + 3% fish oil) is the optimum dose because it has the best growth performance and best feed efficiency that is specific growth rate (4.67%), total feed consumption (262,9 g), feed efficiency (61% ), fat retention (2.805%), and survival rate (80%).
