Abstract

Oryzias hubbsi's distribution is rarely discussed, as it is believed to only occupy the western part of Java, while its conservation status is Near Threatened (NT) as of 15 October 2018 on the IUCN red list. Specimens of O. hubbsi were recorded from Bandung and Jakarta in the description, other reports for O. hubbsi are commonly from Southern Sumatra-Western Java (SWJ) ecoregion in Java. However, an unexpected discovery of the genus Oryzias in Semarang freshwater opens up opportunities for the hidden spread of O. hubbsi to Central Java, and especially to other ecoregions which is Central and East Java (CEJ). Morphological approaches with distinctive O. hubbsi characters, complemented by molecular approaches with O. hubbsi samples from the Bogor population, confirmed similarities of species between both populations. Genetic distance using p-distances between both populations was below 2%, both populations made obvious clusters with a gap of 0.5%, and differed by five nucleotide base sites only. This new distribution record of O. hubbsi can be a foundation for conservation and domestication planning efforts.

Abstract

Mudskipper is amphibious fish that inhabited sandy beaches, mudflat, and mangrove areas. This fish is euryhaline because of its tolerance to varying salinity as well as pH, temperature, conductivity, and dissolved oxygen. This study aimed to identify the taxonomy status of mudskipper in Banua Pangka Mangrove Ecotourism, Seta-Seta Beach, and Masiae River, it was expected to be additional information used as a basis for management and benefaction in taxonomic and ecological aspects. The sampling method of this study was purposive sampling. Morphological identification was carried out by observing morphometric and meristic character. The result found two mudskipper species from three sampling sites, namely Periophthalmus argentilineatus and Periophthalmodon freycineti. Water quality parameter values at three sampling locations were within the optimal range for mudskipper species according to the previous study. The temperatures ranged from 28-33 Celsius, the dissolved oxygen ranged from 2.04-6.74 mg/L, the pH ranged from 6.57-7.1, conductivity ranged from 3.47-41.2 mS/cm, and the salinity ranged from 1.7-2.58 per-mille.

Abstract

Hormonal fluctuations in livestock will affect vaginal cytology good overview on the condition of estrous until pregnancy. The purpose of this study was to determine the physiological condition of Ongole crossbred (PO) cow during estrous and determine pregnancy by the description of vaginal epithelial cells, progesterone, and estrogen hormone profiles. The materials were used 35 cows with physiological status (estrous, 5th pregnancy period, 16th pregnancy period, 22nd pregnancy period, and 60th pregnancy period). Samples of Vaginal smear were stained with Giemsa, then it was observed using a microscope, with 40 times magnification. The progesterone and estrogen were analyzed by the ELISA method. The parameters measured were the percentage of vaginal epithelial cells, such as (parabasal, intermediate, and superficial) started estrous phase until the time of pregnancy in cows (5, 16, 22, and 60 days), hormone concentration, as well as the presence or absence of leukocytes. The result showed the Ongole crossbred cow estrous phase percentage of superficial cells 56.27%±6.49 higher than 26.23%±7.98 intermediate cells, followed by parabasal cells 17.50%±4.74. While in Ongole crossbred that were 5th pregnancy period until the 60th predominantly intermediate cell 80.43%±1.31, then the superficial cells 18.09%±1.30 and 1.48%±0.04 parabasal cells. Progesterone concentration was 63.74±1.07 ng.mL-1 in estrus cows, and steadily increased 93.71±0.94 ng.mL-1 to 149.5±0.71 ng.mL-1 in pregnant cows (5-60 days). The concentration of high estrogen levels were 122.38±0.63 ng.mL-1 in the estrous phase, then decreased 81.54±0.44 ng.mL-1 in the pregnancy phase. In conclusion, the concentration of hormone showed a diagnosis of pregnancy, which done by looking at changes in vaginal epithelial cells at the Ongole crossbred cow, and the cow estrous phase showed greater superficial cells compared by pregnant cows (5-60 days). Keywords: diagnosis of pregnancy, estrous, hormone, Ongole crossbred of cow, vaginal cytology.

Abstract

The aim of this research is to know the level of MDA, motility, and viability spermatozoa of C. carpio L. in cold storage time at 4°C. This study used treatment extenders that were NaCl 0.9% as control, diluent of egg yolk with concentrate 0%, 5%, 10%, 15%, and storage in 0 h, 24 h, 48 h, 72 h, and 96 h at 4°C. The data were analyzed using ANOVA (P<0.05). The results showed that the quality (motility and viability) of spermatozoa C. carpio L. punten strain in cold storage could be maintained at 96 h. The optimum storage for motility was found in diluent of egg yolk concentrate 5% at 48 h. MDA levels of semen from C. carpio L. Punten strains after being stored at cold temperatures increased at 0 h to 24 h, then decreased after 48 h of storage and increase at 72 h - 96 h stored. Egg yolk concentration and storage time had a significant effect on MDA levels. There is a negative correlation between MDA levels and motility. There was no correlation between MDA levels and the viability of spermatozoa C. carpio L. punten strain. Keywords: C. carpio L, Egg yolk, Malondialdehyde, Motiliy, Viability

Abstract

The Minnow Trap is a simple sampling gear, efficient, easy to operate, affordable, easy to make, and has been used in research in the fisheries and aquatic ecology for more than 90 years. The brightness, color, and visual obstruction of fishing gear or fish traps affect the behavioral response of target fish, considering that each fish has a specific level of color sensitivity. The color effectiveness test of fishing gear is an important prerequisite for the use of sampling tools, and it needs to be evaluated to understand the gear performance and avoid potential sampling bias. The purpose of this study was to test the color effect of the minnow trap on diurnal fish in the Gajah Mungkur Reservoir waters. The research was carried out in Gajah Mungkur Reservoir, Wonogiri Regency, at two stations. The sampling conducted at 09.00 - 11.00 and 13.00 - 15.00 Indonesian West Time, where the initial survey is estimated to be the highest time for diurnal fish activity. The minnow trap used in this study is four colors vinyl-painted double funnel cylindrical minnow trap with a 5x5 millimeter mesh size and a conventional umbrella minnow trap used as control. The sampling results are then recorded on the datasheet and analyzed using Microsoft Excel. CPUE (Catch Per Effort Unit) of each unit is then calculated and statistically analyzed by Kruskal-Wallis test and Kolmogorov-Smirnov normality test through SPSS 25.0 software. The test result of five unit minnow traps from 40 installations and two hours of deployment time, 80 individuals were captured, consisted of seven species of freshwater fish. CPUE values ranking consecutively from the highest from silver units (1.375), black (1.25), green (1.125), red (0.9375), and control (0.3125). The Kruskal-Wallis analysis showed that all tested units do not have a significant difference. Keywords: Color, catch per unit effort, fish, minnow trap.
