Increased Blood Glucose Level on Pelagic Fish as Response to Environmental Disturbances at East Coast Pangandaran, West Java

Abstract

Pananjung Pangandaran Nature Reserve Area is one of the tourism destinations in Indonesia, which has large biodiversity. The environmental stressors such as pollutants can reduce the biodiversity of fish. Many physiological changes occur in response to environmental disturbances. One of these responses is blood glucose levels. The objective of this study was to evaluate the quality of the waters environment through the glucose levels of pelagic fish found in the study area. This research was conducted at Pangandaran Nature Reserve. The research was carried out using observational method. The research measured environmental parameters, such as water temperature, dissolved oxygen levels, and carbon dioxide concentrations and blood glucose level of pelagic fish. Five species had high glucose level such as Lactarius lactarius (173 mg/dl), Carangoides Praeustus (105.5 mg/dl), Scomberomorus plumieri (140 mg/dl), Rastrelliger kanagurta (202 mg/dl) and Trichiurus lepturus (136.3 mg/dl). In conclusion, the study indicated that the quality of East Pangandaran Beach Region, West Java has decreased quality based on the increased blood glucose levels on pelagic fish.
