Abstract

The examination on variations of morphological characters among 35 specimens of Calloselasma rhodostoma (Kuhl, 1824) from four different populations in Indonesia has been completed in this study. Univariate and multivariate analyzes allowed us to recognize the clustering of four populations through morphological diagnosis. The results of the average body size (Total Length) showed that the largest male is from Kangean Island (579.33 mm), while the largest female is from Java (841.07 mm). Comparison of meristic analysis represented three clusters from Principal Component Analysis (PCA) which is considered to be independent population. Here we also described three types of cephalic scalation variation that called small accessories scales and their distribution in Indonesia.  Keywords: C. rhodostoma, Indonesia, Meristic, Morphometry, Viperidae.

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.

Abstract

The potential for genotoxicity of pesticides is currently one of the world's concerns. Chlorpyrifos is the organophosphate active ingredient with the largest sales, but the potential for genotoxicity in amphibians is still not widely known. The purpose of this study was to assess the genotoxicity effect of a commercial chlorpyrifos formulation Dursban 200EC in F. limnocharis tadpole erythrocyte (Anura: Dicroglossidae) under acute and chronic exposure using by micronucleus assay. Acute and chronic toxicity tests consisted of negative control, positive control, and 0.4, 0.8, and 1 µg.L-1 of chlorpyrifos with three replications. A toxicity test was carried out on ten tadpoles (Gosner 25) from artificial reproductions in each treatment. The results showed that the formulation of Dursban 200EC in low concentrations (0.4 µg l-1) had the potential to induce DNA damage in erythrocytes of F. limnocharis tadpoles, and there was a positive correlation between chlorpyrifos concentrations and an increase in the frequency of MN. Erythrocytes exposed to chlorpyrifos in both acute and chronic treatment had significantly different MN frequencies between negative and positive controls, 0.4, 0.8, and 1 µg.L-1 (p<0.01). Meanwhile, positive controls were not significantly different from 1 µg.L-1 ( p>0.05). However, the increase in the frequency of MN in chronic treatment was almost twice as high.
