Abstract

Abstrak Ikan merupakan salah satu biota perairan yang digunakan sebagai bioindikator karena sangat peka terhadap perubahan lingkungan perairan. Kondisi perairan yang tidak mendukung dapat menyebabkan stress pada ikan yang salah satunya ditandai oleh perubahan kadar glukosa darah ikan. Tujuan penelitian ini adalah untuk menganalisis hubungan kualitas perairan Sungai Brantas dengan kadar gula darah ikan gambusia (Gambusia affinis). Penelitian dilaksanakan pada sepuluh lokasi sampling di sepanjang aliran Sungai Brantas meliputi DAS Brantas wilayah Batu, Malang, Kediri (2 lokasi), Jombang, Blitar, Tulungagung (2 lokasi), Surabaya dan Mojokerto. Masing-masing lokasi (stasiun) terdiri dari 3 sub stasiun. Parameter yang diukur sebanyak enam parameter kualitas air (in-situ dan ex-situ) dan mengambil sampel Ikan Gambusia untuk diukur kadar gula darahnya. Hasil penelitian menunjukkan bahwa kadar gula darah tertinggi dan melampaui batas normal ditemukan pada sampel Ikan Gambusia yang ditangkap di wilayah Mojokerto. Kondisi ini berkaitan erat dengan rendahnya kadar DO dan tingginya konsentrasi BOD, ammonia, dan fenol di lokasi tersebut. Abstract Fish is one of the aquatic biota that is used as a bioindicator because of its sensitivity to changes in the aquatic environment. Unfavorable water conditions can cause stress in the fish which is characterized by changes in fish blood glucose levels. The purpose of this study was to analyze the relationship between the water quality of the Brantas River and the blood glucose of gambusia fish (Gambusia affinis). The study was conducted at ten sampling locations along the Brantas River by measuring six water quality parameters (in-situ and ex-situ) and taking samples of gambusia fish to measure blood glucose levels. The results showed that the highest blood glucose levels and beyond the normal limit were found in samples of gambusia fish caught in the Mojokerto region. This condition is significantly related to the low levels of DO and high concentrations of BOD, ammonia, and phenol in the location.
