Abstract

Milkfish (Chanos chanos) is included as a fish with high economic value. Milkfish is often cultivated and developed by the community because of its relatively fast growth. The composition of milkfish food certainly affects the growth and development of fish so that fish farming can be carried out properly. Therefore, a literature review related to the composition of the stomach of milkfish is important. The study was conducted by searching, reviewing, and collecting appropriate library data regarding the composition of the stomach contents of milkfish (Chanos chanos) in Indonesia. Research related to the composition of the stomach contents of milkfish totaled 19 articles. The highest frequency of article publications in 2019 (5 articles). The composition of the stomach contents of milkfish consists of zooplankton, phytoplankton, detritus, and plant fragments. The type of food most consumed by milkfish is phytoplankton from the Chlorophyta and Cyanophyta groups.

Abstract

Mercury (Hg) belongs to a group of heavy metals that can pollute the environment. Pollution caused by mercury in the environment will cause bioaccumulation in aquatic biota, which then impacts human health. Mercury, especially in the form of methyl mercury, can be harmful to the central nervous system, causing sensory impairment and even permanent paralysis. Mercury pollution comes from various mining activities, industry, agriculture, household waste, and mercury mining itself. Accumulation of mercury in excess of quality standards can be dangerous and cause many negative impacts. This study examines pollution caused by mercury in Indonesian waters. The results showed that the objects most polluted by mercury are water, sediment, and aquatic biota. The highest percentage of pollution is found in rivers (39%), and the lowest in lakes and reservoirs (3%).
