“…To date, limited information is available concerning elemental contamination in the giant mudskipper. Few studies have been carried out to determine if the giant mudskipper is a suitable potential bioindicator species for elemental pollution in intertidal zones (Ikram et al, 2010;Buhari and Ismail, 2016;Looi et al, 2016;Ng et al, 2019). In Malaysia, Ikram et al (2010) proposed that the giant mudskipper could be used as a potential bioindicator for copper (Cu), lead (Pb), and cadmium (Cd) pollution in intertidal zones.…”

The elemental pollution in the intertidal zone of the West Coast of Peninsular Malaysia is of concern because this place is an ultimate sink of anthropogenic contaminants. In this study, the elemental concentrations (Al, Fe, Ba, Co, Cu, Cr, Mn, Ni, Pb, Zn, As, and Cd) in various tissues (muscle, gill, liver, gastrointestinal tract, and scale) of the giant mudskippers (Periophthalmodon schlosseri) from the West Coast of Peninsular Malaysia were determined by the inductively coupled plasma-mass spectrometry. The potential health risks associated with fish muscle consumption were assessed using estimated weekly intake (EWI), target hazard quotient (THQ), and target cancer risk (TR). The results showed that relatively high concentrations of Fe (1,641.91 ± 96.77 mg/kg), Ba (7.07 ± 0.05 mg/kg), Co (0.32 ± 0.00 mg/kg), Mn (36.08 ± 0.04 mg/kg), and Ni (4.43 ± 0.06 mg/kg) were found in the fish scales, suggesting the uptake waterborne elements via dermal exposure. However, all studied elements in the fish muscle were below the national and international food permissible limits. Health risk assessment through the estimation of THQ suggested that long-term exposure of As through fish consumption would cause possible non-carcinogenic risk. Also, the estimation of TR indicated that consumers are susceptible to cancer risks because of Cr and As exposure via fish consumption. Thus, for a developing country like Malaysia, it is recommended to include continuous monitoring of intertidal zones, using potential bioindicators, to assess ecosystem health status and safeguard human health. Additionally, mitigation strategies to address estuaries contamination and efforts to conserve and sustain natural resources should be established.

Immunohistochemical techniques have been used to identify Metallothionein3 (MT3) expression specifically to detect MT3 levels in the kidney. The techniques employed are highly sensitive, thus allowing the detection of the very low amount of proteins with the use of antibodies. The present study aimed at identifying the MT3 expressions and localizations in the kidney tissue of estuarine catfish Arius thalassinus from Kuala Gula using immunohistochemical methods. Primary mouse monoclonal anti-MT3 (1F11), primary antibody (1:2000), secondary antibody, and Goat anti-mouse IgG2 (1:2000) were used. MT3 bands were detected using (Santa Cruz kit USA method). Heavy metals (Cd, Pb, Zn, and Cu) were determined using aqua regia’s methods followed by analyses with AAS. The results showed high expressions of Metallothionein3 (MT3) with an increasing concentration of heavy metals. Large catfish A. thalassinus had a higher accumulation of heavy metals concentrations, therefore, exhibiting higher expressions than smaller-sized fish. The concentration of heavy metals in fishes were: Zn (284.00 ±29.7, 259.32± 23.2 and 240.90±20.3 μg/g-1 d.w), Cu (7.00±1.7, 6.90±1.3 and 5.60±1.8 μg/g-1 d.w), Pb (66.80±10.8, 35.31±6.4 and 26.02±6.9 μg/g-1 d.w) and Cd (1.32 ± 0.12, 1.19 ±0.12 and 1.20± 0.09 μg/g-1 d.w) in large, medium and small fish respectively. The results of this study suggest its suitability as a biomarker candidate for pollution assessment in the aquatic environment. The different MT3 expressions in different sized fish and different polluted places showed the potential use of MT3 as a biomonitoring biomarker for heavy metals exposure in an aquatic environment.

“…In 2009, Hg and Pb content on water has been exceeding the maximum concentration, but even under maximum level on sediment (Sofarini et al 2010). Several researchers demonstrated that the giant mudskipper fish can accumulate and regulate heavy metals (Cu, Zn, Pb, Cd, and Ni) in its tissues: scale, bone, operculum, intestine, liver, and cartilage (Buhari and Ismail 2016). In addition, the fish can accumulate heavy metals (Cu, Zn, Pb, Cd, and Ni) on their muscle, but lower than liver, intestine, and cartilage (Buhari and Ismail 2017).…”

Abstract. Hidayaturrahmah, Mabrur, Santoso HB, Sasmita R, Rahmy USA, Badruzsaufari. 2019. Short Communication: Protein profiles of Giant Mudskipper and its potential use as biomarker candidate for heavy metal contamination in Barito Estuary, Indonesia. Biodiversitas 20: 745-753. Giant mudskipper (Periphthalmodon schlosseri, Pallas 1770) is one of important biological diversity that potential as bio-indicator in environment assessment which is heavy metal contamination. These fish are susceptible to ambient environment, that effect to their physiological mechanism including protein synthesis and expression. This research aims to identify protein profiles of giant mudskipper muscle and review its potential application as a biomarker for heavy metal contamination in Barito Estuary of South Kalimantan. Total proteins were isolated from fish muscle using Tris EDTA buffer and then precipitated using Ammonium sulfate salt. The protein concentration was measured using Bradford assay and then separated based on molecular weight using the SDS-PAGE method. The result showed muscle proteins of giant mudskipper could be precipitated on optimum condition at Ammonium sulfate saturation 60-70% which protein concentration 5.106 mg.mL-1. The protein separated into 20 bands for raw and precipitated proteins which molecular weight ranging from 33 into 184 kDa. Further study is needed for protein identification based on amino acids sequence of protein bands for biomarker discovery and validation.
