Abstract. Hertika AMS, Supriatna, Darmawan A, Nugroho BA, Handoko AD, Qurniawatri AY, Prasetyawati RA. 2021. The hematological profile of Badher fish (Barbonymus altus) to evaluate water quality in the Badher Bank Conservation Area, Tawangrejo Village, Blitar District, East Java, Indonesia. Biodiversitas 22: 2532-2541. Badher fish (Barbonymus altus) is endemic to the Brantas River. After years presumably extinct, the Badher fish was found again in 2010 in the Brantas River, Tawangrejo Village, Binangun Sub-district, Blitar District, East Java, Indonesia. A conservation area, called a Badher Bank, was established in the location. However, human activities, such as ecotourism and agricultural waste runoff, have changed water quality and increased water pollution in the Badher Bank Conservation Area. This research objective was to observe the hematological profile of badher fish and a set of water quality parameter measurements as an environmental factor that affected fish life. Data were obtained from four research stations with three replications every two weeks from August to October 2020 at the Brantas River streamline inside the Badher Bank Conservation Area. The Canonical Correspondence Analysis (CCA) method was applied to determine the correlation between water quality and hematological profile. According to the data analysis, the water quality at Stations 1-3 in the research location was normal, and Station 4 was polluted. The analysis also showed that the low dissolved oxygen and high ammonia affected the hematological conditions of Badher fish. All water quality parameters affected the condition of leucocytes, erythrocytes, and hemoglobin in moderate concentrations. Besides that, micronuclei and hematocrit conditions were strongly influenced by ammonia, temperature, pH, and current velocity in high concentrations, while Dissolved Oxygen (DO) and Total Suspended Solid (TSS) affected low concentrations.

Effect of environmental factors on blood counts of Gambusia affinis caught at Brantas River watershed, Indonesia

“…In normal fish, the number of erythrocyte cells ranges from 1,050,000 to 3,000,000 cells/mm 3 , 13 while the number of leucocyte cells ranges from 20,000-150,000 cells/mm 3 . 71 Therefore, erythrocyte levels in Gambusia affinis caught in Blitar, Surabaya, and Mojokerto can be considered low.…”

“…The use of particular biomarkers for assessing environmental quality and the health of fish in degraded environments has proven to be useful and widely-used. 12 , 13 Fish are commonly employed to assess the quality of the aquatic environment and are recognized as bio-indicators of pollution. 14 , 15 Fish live in close proximity to their environment and are thus vulnerable to physical and chemical alterations to it, which may manifest in components of their blood.…”

Performance of Metallothionein Biomarker from <i>Sulcospira testudinaria</i> to Assess Heavy Metal Pollution in the Brantas River Watershed, Indonesia

“…Previous research found that Sulcospira testudinaria was present in the Cikeruh River [Lutfi et al, 2020], Code River [Hellen et al, 2020], Meru Betiri National Park [Suratno et al, 2020], Gunung Kidul [Isnaningsih and Listiawan, 2010], and the Brantas River [Febbyanto et al, 2015]. This species was used as a bioindicator for aquatic environmental health [Hertika et al, 2021], and was used to measure the results of efforts to reduce levels of organic matter in aquaculture wastewater [Lailiyah et al, 2021].…”

A checklist of native freshwater fish from Brantas River, East Java, Indonesia

“…These fish have long been used by the communities that live near the river as a source of animal protein (Pratama et al 2020;Valen et al 2022b), while some are used for the aquarium trade (Gani et al 2021;Ndobe et al 2022;Nurjirana et al 2022). Rivers also provide socio-economic value as they are widely used as water sources for domestic activities, tourism, agriculture, and other economic activities (Hertika et al 2021;Nurhayati et al 2021).…”
