Morphological profile of L2 Anisakis typica on Indian Mackerel (Rastrelliger kanagurta) from Sedati Fish Auction, Sidoarjo-East Java, Indonesia using Scanning Electron Microscope (SEM)

Abstract

The aim of this research was to determine Anisakis species that infected Indian mackerel fish in Fish Auction Sedati, Sidoarjo-East Java, Indonesia based on morphometric observation using a binocular microscope and morphological profile using SEM. This study was done on February-March 2019 with 30 Indian mackerel (Rastrelliger kanagurta) were collected from Fish Auction Sedati, Sidoarjo and examined for Anisakis. Anisakis that collected, observed using a binocular microscope and SEM. The result showed there was 10% prevalence of Anisakis. All of Anisakis examined were classified as Anisakis type 1. Based on the body length of Anisakis, all of Anisakis that collected were assumed as Anisakis L2. The conclusion based on morphometric and morphological characteristic showed that Anisakis examined were classified as L2 stage larvae of Anisakis typica.

Intraspecific Genetic Variation of Anisakis typica in Indian Mackerel Caught from the Gulf of Thailand, Samut Songkhram Province

“…In our investigation, molecular analysis using ITS and COII revealed that 17 Anisakis samples from Indian mackerels captured in Thailand are A. typica (Diesing, 1860, Nematoda: Anisakidae), also documented in several surveillances of Indian mackerels caught in Indonesia [ 30 , 31 ]. These findings may indicate that Indian mackerels are an important intermediate host of this parasite in Southeast Asia.…”

“…In several countries of Southeast Asia such as Indonesia, Malaysia, Myanmar, and Thailand, they are an economically important marine fish [ 27 , 28 ]. In the past, the Anisakis parasite was found in Indian mackerel in some countries, including China [ 29 ], Indonesia [ 30 , 31 ], and Malaysia [ 32 ] but has never been reported in Thailand. However, our latest study detected Anisakis infections in Indian mackerel fish from the Samut Songkhram fish market [ 15 ].…”
