Abstract

Tridacna sp. is one of the protected heritage in Indonesia, because its population has declined dramatically. Tridacna sp. is the largest type of shellfish in water. Like a clam, Tridacna sp. can be used as a bioindicator of the aquatic environment because it can accumulate more heavy metals than other aquatic organisms due to its nature as a filter feeder. This study aims to determine the health condition of Tridacna sp. in the waters of Obi Island with a histopathological analysis approach. The histopathological analysis aims to see the level of tissue damage due to the accumulation of heavy metals. Observation of water quality was also observed in this study. Water quality parameters observed in-situ are temperature, brightness, salinity, pH, and dissolved oxygen. While the water quality parameters observed ex-situ are nitrate, orthophosphate, ammonia, iron (Fe), and nickel (Ni). Observations show that the water temperature is at 27.99 ℃. Water brightness is at 13 m. Salinity is at 32.13 mg / l. The acidity of the waters is 8.64. Ammonia is at 0.4 mg / L. Nitrate is at 0.009 mg / L. Orthopedics are at 0.016 mg / L. Dissolved oxygen waters are at 3.77 mg / L. The iron (Fe) level of water is at 0.6 mg / L. The level of nickel (Ni) waters is at 0.06 mg / L. This study shows the health condition of Tridacna sp. the histological approach shows that the condition of the network has changed. Symptoms of this change indicate the condition of the Tridacna sp. degeneration and cell necrosis. This change is thought to be influenced by heavy metals. Heavy metal content in liquids exceeds the quality standard threshold.Keywords:  Tridacna sp.; Heavy metal; Water quality; histopathological.

Abstract

This study aims to determine the content of nickel (Ni) and iron (Fe) as well as histopathological analysis of marine fish in Obi Island waters as a bioindicator of pollution. Besides, water quality conditions were carried out in-situ and ex-situ observations. The parameters observed were temperature, brightness, salinity, pH, dissolved oxygen, nitrate, orthophosphate, ammonia, iron (Fe), and nickel (Ni). The results showed the temperature range between 26.48 ℃ to 27.99 ℃ below the quality standard or low temperature. The brightness of the relationship between 12 m and 13 m is under quality standards. The salinity range between 31.01 ppt to 32.13 ppt below the quality standard. The pH range is from 8.6 to 8.7 in high or alkaline conditions. Ammonia range between 0.4 mg / L to 0.7 mg / L exceeds the quality standard. The range of nitrate between 0.009 mg / L to 0.012 mg / L exceeds the quality standard. The range of phosphate between 0.016 mg / L to 0.019 mg / L exceeds the quality standard. The DO range between 3.68 mg / L to 3.77 mg / L lower than the quality standard. The metal range of 0.6 mg / L to 0.9 mg / L exceeds the quality standard. The range of Ni metal between 0.06 mg / L to 0.09 mg / L exceeds the quality standard. Histopathological analysis showed that the liver had a hemorrhage, degeneration of blood vessels, vacuolate degeneration, necrosis, or cell death. The muscles experience edema, degeneration of muscle fibers, atrophy of muscle bundles, vacuolar degeneration of muscle Bundles, hemorrhage, infiltration of lymphocytes, and necrosis. The intestine experience infiltration of lymphocytes, melanomacrophages, and necrosis. While P. tayenus fish ovaries showed necrosis structure oocytes. This research can be a reference for warning of heavy metal pollution in Obi Island waters, binding to the nature of heavy metals that can accumulate in fish tissue.Keywords: Water quality; Heavy Metal; Pollution; Histopathological; Obi Island.
