Abstract

Kijing Taiwan ( Anodonta woodiana ) is found in water with muddy substrate. Kijing Taiwan lives in bottom waters and is relatively settled. Kijing Taiwan is a filter feeder organism that can filter water and is able to survive in polluted environment, so it can be used as a bio-indicator of a water body. The study was conducted in the Public Hatchery Unit (UPR) Sumber Mina Lestari. Profile hemocytes in Taiwan Kijing influenced by environment pollution inducer among others. Hemocytes were observed consisting of Total Haemocyte Count (THC) and Differential Haemocyte Count (DHC). The results show that the profile of hemocytes (THC and DHC) of Kijing Taiwan is not polluted. Results from aquaculture pond water quality measurements indicate that the indicators of the water quality i.e. temperature, pH, dissolved oxygen, and ammonia are still within normal limits. However, in TOM test, BOD and soil organic matter has exceeded the normal limits. The existence of organic matter became the medium of life for Kijing Taiwan, due to its role as a biofilter among other organic materials. Keywords: Hemocytes Profile, Kijing Taiwan, Water Quality.

Highlights

  • Public Hatchery Unit (UPR) Sumber Mina Lestari is a regional center for the cultivation of freshwater fish

  • The results show that the profile of haemocyte (THC and Differential Haemocyte Count (DHC)) of Kijing Taiwan is not polluted but there has been found hyaline cells in the stage of introduction of foreign objects; it is clear that Kijing Taiwan can be utilized as an early indicator of water pollution [2]

  • Based on the research results, Total Haemocyte Count (THC) for Kijing Taiwan taken in UPR Sumber Mina Lestari ranges from 40.33 x 104 to 90.33 x 104 cells.mL-1

Summary

Introduction

Public Hatchery Unit (UPR) Sumber Mina Lestari is a regional center for the cultivation of freshwater fish. It is located in Banjartengah, Sumbersekar Village, District Dau, Malang Regency. There are mollusks that live inside Kijing Taiwan. Farmers are still dependent on the use of various chemicals such as inorganic fertilizers and pesticides [1]. The use of inappropriate dose of chemicals often leaves residues in the environment. One living organism that meets the requirements as bio motor in aquaculture ponds of UPR Sumber Mina Lestari is the freshwater mussel or referred to as Kijing Taiwan (Anodonta woodiana)
