Abstract

Exposing land surfaces through fossil excavation activities can increase sediment loads and toxic chemicals that are discharged into water bodies. This can have negative effects on receiving environments and their habitats. The aim of this study was to evaluate the dry body weight and physiology (whole body lipid and protein contents) of guppy fish (Poecilia reticulata) in Pucung River, a former archaeological excavation site in Sangiran, Indonesia. Little is known about their physiology in this river. Guppy fish and water were sampled from eight sites along the Pucung River, two sites (Site 1 and Site 2) were situated upstream of the archeological excavation site, one site (Site 3) was at the archeological excavation site, and five sites (Site 4 - Site 8) were situated downstream of the archeological excavation site. The distance between the two sites was 500 m. The length and total weight of captured male fish were measured. Lipid and protein contents of male fish were determined gravimetrically, and the results were conveyed as Joules. A total of 240 male individuals were captured with a length between 1.24 and 3.95 cm. The weight of male guppies varied between 13.0 and 38.2 mg. Male guppies' average lipid and protein contents ranged from 0.0509 J to 0.2635 J and 0.0842 J to 0.1648 J, respectively. The smallest weights and lipid contents among individuals were found in the excavation site (Site 3) and a site downstream (Site 4). These individuals also had the smallest protein contents, along with those from Site 5 to Site 7. Fish dry weight and lipid content were positively correlated with water pH and dissolved oxygen, and negatively correlated with biological oxygen demand. These findings showed that guppy dry weight and lipid content may be utilized to assess the impact of human activities on river health.

Abstract

Hormon steroid sintetik yang terkandung dalam pil Keluarga Berencana (KB) telah menjadi kontaminan di perairan global. Hormon etinilestradiol dan levonorgestrel memberikan dampak negatif terhadap perkembangan, perilaku dan kelangsungan hidup ikan di lingkungan perairan. Di Indonesia, perhatian terhadap potensi dampak etinilestradiol dan levonorgestrel terhadap organisme bukan target perairan masih sangat terbatas. Studi ini dilakukan untuk memahami perubahan kandungan energi dalam lemak dan protein pada ikan seribu (Poecilia reticulata) yang terpapar estrogen dan progestogen (campuran etinilestradiol dan levonorgestrel). Ikan guppy jantan dipapar dengan enam konsentrasi campuran etinilestradiol/levonorgestrel yang berbeda, yaitu 0 ng/L etinilestradiol dan levonorgestrel, 0,3 ng/L etinilestradiol dan 1,5 ng/L levonorgestrel, 3 ng/L etinilestradiol dan 15 ng/L levonorgestrel, 30 ng/L etinilestradiol dan 150 ng/L levonorgestrel, 300 ng/L etinilestradiol dan 1500 ng/L levonorgestrel, dan 3000 ng/L etinilestradiol dan 15000 ng/L levonorgestrel selama tujuh hari dan tidak diberi pakan selama percobaan. Kandungan energi diestimasi setelah perlakuan secara gravimetri. Penelitian ini menunjukkan bahwa paparan jangka pendek pil keluarga berencana yang mengandung campuran etinilestradiol dan levonorgestrel berturut-turut hingga 3000 ng/L dan 15000 ng/L tidak berbeda nyata dengan kontrol. Berdasarkan hasil penelitian ini dapat disimpulkan bahwa paparan jangka pendek pil KB tidak mempengaruhi kandungan energi pada ikan seribu.
