White spot syndrime virus (WSSV) is a highly contagious disease in shrimp culture and causing 100% death within 3-10 days of clinical symptoms. WSSV can infect shrimp in post larvae stage (PL) to a size of 40 g. This study was aimed to determine the effect of different salinity against WSSV infection level in post larvae vannamei shrimp (Litopenaeus vannamei). In this study PL 40 size of vannamei shrimp infected with WSSV in virus concentration 20 μg.mL-1 in three different salinity is 5 ppt, 15 ppt, 25 ppt for 4 hours using the soaking method then maintened for 7 days post-infection and then infection level and water quality observed. Data analysis used simple linear regression and F test with a confidence level 95% (P <0.05). The results indicate changes in behavior between healthy and infected shrimp in three levels (mild, moderate, severe). The highest total mild infection in salinity treatment of 25 ppt by 30%, the highest total medium infection at salinity treatment 25 ppt by 37%, the highest total severe infection at salinity treatment 5 ppt by 57%. Shrimp that have mild level of infection are increasing in concominant higher salinity, while the severe infection level has decreases with increasing salinity. Keywords: Infection Level, Litopenaeus vannamei, Post Larvae, Salinity, WSSV

Spermatozoa are male gametes that have an advantage in acting as gene transfer media (SMGT), because in transferring genetic material, sperm uses relatively natural vectors. This study was conducted to know sperm quality of Koi after short electroporation with different voltages using Gene Pulser. The study was conducted using a complete randomized design (RAL) with three (3) replications and five (5) treatments, namely: 10 V.cm-1, 20 V.cm-1, 30 V.cm-1, 40 V.cm-1, and 1 control. Electroporation was done with square wave, 1 ms duration of electroporation, 4 times of electroporation shocks with 0.1 s duration. The results showed that electroporation with different voltage levels significantly affected the motility and viability of sperm. Based on orthogonal polynomial analysis, it was known that the treatment affected motility and viability of sperm with a linear equation y = -0.9x + 5, 4 R² = 0.920 and r = 0.96 for motility and y = -11.26x + 91.61 R² = 0.823 and r = 0.91 for viability, meaning that the higher the level of electroporation the lower the viability and sperm motility produced. From the results of this study, it can be suggested that the electroporation of Koi sperm as a gene transfer medium should be performed at a voltage of 10 V.cm-1. Keywords: electroporation, Koi, sperm quality, transgenesis.

Seaweeds have an inherent capacity to absorb heavy metals from marine water. This intrinsic ability allows these organisms to accumulate much amount of heavy metals over time. This study conducted at Kupang Village, Jabon Sub-District, Sidoarjo District, where almost 40% of the area consists of Gracilaria sp. ponds cultured. The purpose of this study was to analyze the Pb heavy metals concentration in water culture and its concentration in holdfast and thallus of Gracilaria sp. In this research, determination of samples in each pond was taken on day 0 (before planting), 20 days (Initial Production) and on day 40th (Post/Harvest). The aquatic parameters include salinity, temperature, acidity (pH), and dissolved oxygen (DO). Quantitative determination of heavy metals on sample using Atomic Absorption Spectrophotometry (AAS). Determinations of heavy metal accumulation in organism using Bioconcentratin factor (BCF) and Translocation factor was used to calculate the Pb heavy metal translocation process from the base to the tip of Gracilaria sp. The results of the study showed the highest Pb concentration found in the second sampling age 20 days, in pond 1 with 7.61 ± 0.18 mg.kg-1, and pond 2 was 5.35 ± 0.09 mg.kg-1. This concentration has not exceeded the threshold value that might have an effect if more than 8.6 mg.kg-1. The highest Pb level at the holdfast of Gracilaria sp. found at age 0 days before planting, which is 3.38 ± 0.23 mg.kg-1 and decreases to post-harvest (age of 40 days) which is 0.84 ± 0.00 mg.kg-1. The Transaction Factor (TF) of Pb heavy metal value from holdfast to thallus is 1,015 thus Gracilaria sp. absorbs heavy metals in high concentrations at the beginning of planting and is able to release it again before harvest time. Keywords: Bioaccumulation, Gracillaria sp., Heavy Metal, Histological, Red Algae.

Study aims to analyze the genotoxic potential of glyphosate-based herbicide on common carp (Cyprinus carpio L) using Micronucleus and hematological assay. The concentration of Glyphosate-based herbicide in this study was 0 ppm, 1.35 ppm, 1.8 ppm, 2.4 ppm, 3.2 ppm, 4.2 ppm, 6.5 ppm, and 8.7 ppm. Administration of herbicide base on modification of published methods with 96 hours of exposure. This research result has shown that the average number of micronuclei was increased simultaneously with increasing the concentration of herbicide exposure. There are also other types of cell nucleus abnormalities, namely: blebbed, lobed, notched, and binuclear. In the treatment of 0 ppm of herbicide shown blebbed nuclei are 8 ‰, lobed nuclei are 6.6 ‰, notched nuclei are 10 ‰, binuclei is 4 ‰. From the research results, it can be concluded that the LC50-96 hours exposure of the herbicide isopropylamine glyphosate in carp (Cyprinus carpio L.) was obtained at a concentration of 8.57 ppm. Based on the evaluation on hematology, it was found that there was a decrease in the number of erythrocytes, hematocrit, and hemoglobin of fish blood, whereas the number of leukocytes, micronuclei, and other abnormal micronuclei showed an increase along with the increase in the dose of exposure to the herbicide isopropylamine glyphosate, which indicates a genotoxic effect.

In general, the process of naming several species of fish including species from the genus Mystacoleucus is still carried out based on morphological characters, which are often found in almost the same morphological characters in different fish species. Therefore, it is necessary to apply a more accurate identification method, which is a DNA-based identification method called DNA barcoding. The purpose of this study was to identify the species of the genus Mystacoleucus on the Sengguruh Dam molecularly based on the Cytochrome Oxidase C Subunit I (COI) gene. A caudal fin was taken on the test fish and preserved in 95% ethanol solution for molecular identification. The results of the identification showed that the sample belonged to the Mystacoleucus marginatus species with Identity values between 99-100% and E-value 0.0. The data obtained showed that from the calculation of genetic distance presented in the form of data matrix and phylogenetic tree reconstruction, there were 2 species that had a far genetic distance from the M. marginatus sample from the Sengguruh Dam namely M. atridorsalis with the furthest genetic distance of 0.1932-0.2595 and M. lepturus with genetic distance between 0.1117-0.1193. However, there are one species that has the closest distance, M. padangensis with genetic distance between 0.0019-0.0038 and identity values up to 99%.Keywords: DNA barcode, Molecular identification, Mystacoleucus, Phylogenetic COI.
