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

Traditional ponds in Pasuruan City are dominated by milkfish (Chanos chanos). Milkfish take food from the top layer of the seabed in the form of phytoplankton and zooplankton. This study aims to determine the abundance, diversity and dominance of plankton and water quality in traditional milkfish ponds in Pasuruan City. Sampling locations were selected based on the distance of the pond from the sea. Station 1 (near the sea), station 2 (1–3 km from the sea), and station 3 (furthest from the sea). The results showed the availability of natural food for milkfish in the form of phytoplankton and zooplankton. Phytoplankton was found more than zooplankton. The most common phytoplankton division was Bacillariophyta and the least was Euglenozoa with diversity index ranging from 1.64–1.82 and dominance index ranging from 0.24–0.31. The most common zooplankton phylum is Arthropoda and the least is Molluscs with diversity index ranging from 0–1.83 and dominance index ranging from 0.21–1.00. The measurement results of pond water quality parameters such as pH (8.51–9.02), temperature (30.1–32.5°C), brightness (25.5–29.6 cm), DO (3.7–5.7 ppm) and salinity (32.5–33.7 ppt) are still in accordance with the optimal standards of milkfish farming.

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.
