Abstract

The entry of foreign predatory fish into Indonesian open waters had the potential as a disease vector, predation, and damaging food webs that would have a systemic impact on the local ecosystem. In this study, we report the presence of the foreign predatory fish Jaguar cichlid Parachromis managuensis (Günther, 1867) from Central America in the Lingsar River, West Lombok Regency. This record is the first time for this species in Lombok, where previously this fish was found in Java. A description of the morphological characters of the captured specimens is provided in the discussion.

Abstract

Beardless Barb Cyclocheilichthys apogon (Valenciennes, 1842) is a species known from Southeast Asia, including Western Indonesia area (Borneo, Sumatra and Java). In Java Island, it was previously found in the mainland area. This paper provides the first record of C. apogon in the Lembung River, one of the major rivers in Madura Island, thereby extending the species distribution up to 150 km northeast from the earlier record. The specimens of C. apogon were characterized as follows: dorsal fin rays 12; anal fin rays 8–9; pectoral fin rays 17–18; lateral line scales 34–35. A description of detailed morfological characters of a specimen are provided.

Abstract

The Jaguar cichlid, Parachromis managuensis (Günther, 1867), is native to Central America, with introduc­tions reported from West Java and Central Java Provinces of Indonesia. On 7-8 January 2019, sixteen specimens of P. managuensis were collected from Karangkates, the largest hydropower reservoir in East Java Province of Indonesia. A description of the morphological characters of specimens is provided.

Abstract

Catfish (Clarias sp.) is one of the leading fishery commodities in Indonesia. Therefore, many people cultivate catfish, including the members of the Tambak Wedi Catfish Farmers Association (PPL), in Tambak Wedi, Surabaya. Located in the city of Surabaya, the limited water availability encourages catfish aquaculture to be conducted in urban aquaculture. However, pathogen infection became a challenge for PPL Tambak Wedi. The pathogen caused losses for catfish farmers in Wedi Pond. This causes the turnover of farmers to decrease and they have to close the aquaponics pond. One solution that can be done is giving biofloc. Biofloc has 3 main functions, namely improving water quality, as an additional feed ingredient for cultivated organisms and suppressing pathogens. The implementation of this activity consists of three stages, namely: (1) building an experimental pond and sites for catfish farming, (2) the extension and demonstration and (3) the application of biofloc in catfish farming. From this activity, it was found that previously members of the Tambak Wedi Catfish Farmer Association in Surabaya City, East Java, had already applied biofloc but experienced problems so that they were not continued. After this service activity, the cultivators were motivated to re-apply biofloc for their cultivation business.

Abstract

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.
