Abstract

Parasites are a major problem on biota survival or green mussels because parasites are organisms that live in other organisms. Parasites can harm the host they live in because these organisms will absorb nutrients from the host they live on, damage tissues, and cause infection. This study aims to examine the types of ectoparasites and to determine the prevalence and intensity values of cultivated green mussels (Perna Viridis L.) in the Alue Naga reservoir, Banda Aceh. The study was conducted in July 2020, identification of parasites was carried out at the Fish Quarantine Station, Quality Control and Safety of Class 1 Fishery Products in Aceh. The research method was a survey method with a sampling technique using random sampling. Observations were made visually and using a microscope on the target organs in the shell, gills, and mantle. Furthermore, the parasites found in green mussels were identified using the Kabata book (1984). Based on the research results found 4 types of ectoparasites, namely cysts perkinsus sp. (Protozoa) on the coat, Balanus sp. (Crustacea) on the shell, Monogenea (Platyhelminthes) on the gills, Copepoda (Crustacea) on the gills, and it is known that the highest intensity value is 1.16 and the highest prevalence value is 74%. parasite barnacles (Balanus sp.), while the lowest intensity value is 1 and the prevalence value is 1% cysts perkinsus sp. The water quality values were pH 8.7, temperature 29 C, dissolved oxygen 4.8 Ppm, salinity 31 Ppt, depth 1.53 m, brightness 70 cm, and current 17 m / s. The value of water quality parameters in Alue Naga waters is still in the optimum range for the growth of green mussels.

Highlights

The presence of green mussels (Perna Viridis L.) (Bilvavia Phylum Mollusca Class) is widespread in Indonesian waters and it is abundantly found in coastal waters, reservoirs, mangroves, and river estuaries
One of the organisms that have high diversity is in the bilvavia phylum mollusks class
Green mussel (Perna viridis L.) is a type of aquatic organism that lives on the bottom substrate of the waters and attaches to a hard substrate

Summary

Introduction

The presence of green mussels (Perna Viridis L.) (Bilvavia Phylum Mollusca Class) is widespread in Indonesian waters and it is abundantly found in coastal waters, reservoirs, mangroves, and river estuaries. Many coastal communities grow green mussels as a side income in their free time [1]. This statement is supported by [2], that green mussels have potential value to be cultivated, considering the availability of green mussels in nature will having a decrease due to the increased capture. One of the organisms that have high diversity is in the bilvavia phylum mollusks class. The organisms categorized to the bivalve’s class are green mussels (Perna viridis L.). Green mussels (Perna viridis L.) are shellfish that have high economic value and it is favorite food by the public because of their high nutrients content
