Electric shock treatment of Java Barb Fish (Puntius javanicus) sperm using electroporation method on sperm as transfer gen (Sperm Mediated Gen Transfer) has not been implemented in Indonesia. This study was conducted to know the effect of electric shock using gene pulser at different voltage level toward motility and viability of Java barb fish sperm. This research was conducted at Fish Breeding Laboratory, Faculty of Marine and Fisheries and LSIH of Brawijaya University-Malang in May 2017. The trial design used Complete Randomized Design with 3 different treatments and 1 control which each treatment repeated 3 times. The treatments used the Gene pulser with 3 different voltages: A (20 V), B (30 V), C (40 V). The result showed that the electric shock treatment with different voltages level affected motility and viability of Java barb fish sperm. Based on the data analysis used polynomial orthogonal, a linear-form of the relationship among the treatments in the form of equation was found (Puntius javanicus) with R2=0.9815 and equation y = -40.5x + 130.83 with R2= 0.8626. Based on the result of this research, electroporation for Java barb fish' sperm as gene transfer media should be done with voltage 20 V, pulse number 4 times and pulse length 1 ms. Keywords: electroporation, motility, Puntius javanicus, sperm, viability.

Nemacheilus is one of the genera of freshwater fish. The existence of Uceng fish (Nemacheilus fasciatus) in public waters is increasingly rare. Changes in water temperature in the maintenance medium will affect the physiological processes of fish. The purpose of this study was to analyze physiological responses (blood glucose levels, cortisol, and glycogen hormones) of Uceng Fish (N. fasciatus) which were incubated at different temperatures and find out the initial time of Uceng fish adaptation to its new environment. Total of 200 fish were collected from wild catches in the Lekso River, Blitar. Fish tissue collection was carried out to test the profile of glucose, cortisol, and glycogen. The research activities at this stage were carried out by raising the Uceng fish from nature to a cultivation container in an aquarium of size 50 x 30 x 30 cm that given the different temperatures (20°C, 24°C, 28°C and 32°C), and each aquarium is filled with 10 Uceng fish and will be kept for 14 days. ELISA method was used to quantify the parameter. The result of this study showed highest peak of cortisol levels and blood glucose levels was achieved in the treatment of 24°C on the 10th day and the lowest in the treatment temperature of 28°C on the 6th day. The highest glycogen peak was reached at 32°C on day 10 and the lowest peak was reached at 28°C on day 2. We conclude that temperature affects the physiological response (cortisol, blood glucose, and glycogen) of Uceng fish (N. fasciatus). High levels of cortisol and blood glucose indicate stressful fish. Keywords: Fish, Nemacheilus fasciatus, Physiological, Temperature, Uceng.

Successful studies about implementation of electroporation method which sperm becomes gene transfer medium for fish transgenesis have reported. Motility and viability are two major factors in successful of electroporation. The objective of the study was to determine optimal pulse length of electroporation towards the motility and viability of Koi fish sperm. The study was conducted at the Central Laboratory of Biological Sciences and Reproduction of Brawijaya University. The data analysis was conducted using completely randomized design. The electroporation method was carried out using voltage of 30 volt with pulse number of 4 times. The pulse length of the electroporation (based on treatment) was 0.5, 1 and 1.5 ms. The result showed the highest percentage of motility was 3.67% in treatment A (pulse length 0.5 ms) with coefficient correlation R2 = 0.9643 and the best percentage of viability was 79.67% in treatment A (pulse length 0.5 ms) with coefficient correlation R2 = 1. Correlation between the pulse length treatment (electroporation) toward motility and viability of Koi fish sperm, in which longer duration of pulse length treatment (electroporation) would decrease the motility and viability percentage of the fish sperm.Keywords: Electroporation, Motility, Pulse length, Sperm, Viability.
