Suckermouth Catfish (<i>Pterygoplichthys pardalis</i>) In Wajo Regency, South Sulawesi Province: The Heavy Metal Content of Lead (Pb), Mercury (Hg) and Arsenic (As)

Abstract

Suckermouth catfish (Pterygoplichthys pardalis) is a type of foreign fish (South America) which is prohibited from entering Indonesia because it can endanger ecosystems and the aquatic environment by its invasive nature. The existence of janitor fish threatens the sustainability of the endemic fish of Tempe Lake in Wajo Regency. Until now, there has been no study regarding the quality and food safety for the use of suckermouth catfish in the regency. This study aims to analyzed the heavy metal content of lead (Pb), mercury (Hg) and arsenic (As) of janitor fish in Wajo Regency. Samples of janitor fish were taken from three districts in Wajo Regency used a purpossive sampling technique. Analysis of Pb, Hg and As metals on meat, scales/skin, and bones/fins of suckermouth catfish, refers to SNI 2354.5: 2011, SNI 2354.6-2016 and SNI 01-4866-1998. The results show that suckermouth catfish from the three districts are not contains Pb but contains Hg and As which do not exceed the requirements for metal contamination content limits based on SNI 2729: 2013 concerning requirements for quality and safety of fresh fish

Analysis of nutritional content and heavy metals of suckermouth catfish (Pterygoplichthys pardalis) in Lake Sidenreng, South Sulawesi, Indonesia

“…The results of previous research conducted in Lake Tempe also proved that the content of heavy metals (As, Pb and Hg) found in the meat, scales and bones of suckermouth catfish did not exceed the metal content threshold required in SNI 2729:2013 (Amir et al 2020). However, unlike the heavy metal content in P. pardalis found in the Ciliwung River, the concentration of these metals is quite high in P. pardalis meat exceeding the threshold set by the Indonesian Food and Drug Supervisory Agency (BPOM) and the Indonesian National Standard (SNI) (Elfidasari et al 2020b).…”

Extraction and Characterisation of Suckermouth Catfish Collagen

“…It is a common conception that suckermouth catfish are contaminated with heavy metals and other contaminants due to their presence in normally polluted rivers and lakes (45). According to a study in Indonesia, Plecostomus species in the Ciliwung River in Jakarta contain up to 57 metals in their flesh, including three types of heavy metals: lead (Pb), mercury (Hg), and cadmium (Cd), with concentrations exceeding the maximum recommended levels for human consumption (46).…”

Karakteristik mutu abon ikan sapu-sapu (Pterygoplichthys pardalis) dari Perairan Danau Tempe, Sulawesi Selatan

“…Keamanan ikan sapusapu sebagai bahan pangan terkait dengan kemampuannya mengakumulasi logam berat. Hal tersebut dilaporkan oleh (Ernawati, 2014;Aksari et al, 2015;Ismi et al, 2019) bahwa ikan sapu-sapu di Sungai Ciliwung mengandung logam berat dalam jumlah melebihi batas aman yang dipersyaratkan SNI 7690.1-2013 mengenai abon ikan sedangkan ikan sapu-sapu di Danau Tempe mengandung logam berat jenis Hg, Pb, dan Cd pada tingkat yang aman bagi kesehatan (Amir et al, 2020;Kasmiati et al, 2022). Ikan sapusapu juga memiliki kandungan protein yang cukup tinggi yaitu 15,20%, dan kandungan lemak, serat kasar, air, dan abu berturut-turut adalah 6,27%; 2,14%; 67,19%; dan 4,74% (Hasnidar et al, 2021).…”

“…Pengambilan sampel ikan sapu-sapu mengacu pada Kasmiati et al (2022) dengan metode purposive sampling, yaitu peneliti menentukan sendiri lokasi pengambilan sampel berdasarkan beberapa pertimbangan tertentu yang bertujuan agar data yang diproleh lebih representative. Lokasi sampling sesuai dengan penelitian Amir et al (2020), yaitu di Kecamatan Tanasitolo Kabupaten Wajo. Kadar logam berat ikan sapu-sapu di lokasi tersebut lebih rendah dari ambang batas yang dipersyaratkan oleh SNI 7690.1-2013 sehingga dikategorikan aman diolah untuk dikonsumsi.…”
