Judul: Diversity of Helminth Parasites in Mackerel Tuna (Euthynnus affinis Cantor, 1849) from Banten Waters, Indonesia
Abstrak: Ikan tongkol (Euthynnus affinis) merupakan salah satu ikan target yang ditangkap oleh nelayan di Selat Sunda dan termasuk dalam 10 besar komoditas unggulan yang ditangkap di Teluk Banten. Salah satu ancaman terhadap populasi ikan tongkol di perairan tersebut adalah adanya infeksi oleh parasit. Penelitian ini bertujuan menganalisis keragaman jenis cacing parasitik pada ikan tongkol dari Perairan Banten dan menduga korelasi jumlah cacing parasitik terhadap kondisi biologis ikan sebagai inang dan lingkungannya. Ikan tongkol didapatkan dari PPN Karangantu dan PPI Muara Angke. Ikan kemudian dibedah dan beberapa organ diperiksa untuk menemukan parasitnya. Parasit yang ditemukan dipreparasi dengan metode pewarnaan dan diidentifikasi. Cacing parasitik yang ditemukan berbeda pada kedua lokasi. Taksa yang ditemukan pada penelitian ini adalah Nematoda, Monogenea, Acanthocephala, dan Digenea. Parasit dengan prevalensi, intensitas, dan kelimpahan tertinggi dari Selat Sunda adalah Neorhadinorhynchus sp. dan pada Teluk Banten Hexostoma euthynni. Keberadaan cacing parasitik di kedua lokasi tidak berkorelasi terhadap faktor kondisi, panjang total, bobot total ikan, maupun suhu permukaan laut dan klorofil-a., Mackerel tuna (Euthynnus affinis) is one of the target fishes caught in Sunda Strait and one of the top ten fishery commodity in Banten Bay. One of the threats on mackerel tuna’s population in Banten waters is helminth parasite infections. This study aims to know the diversity of helminth parasites infecting mackerel tunas in Banten waters and determine the correlation between helminth parasites with biological condition of the fish and their environment. Mackerel tunas were obtained from PPN Karangantu and PPI Muara Angke. Specimens were dissected and some organs were examined for parasites. Staining method were used to prepare the parasites for identification. The results showed that the diversity of helminth parasite was from both locations. Taxa of the parasites in this study were Nematoda, Monogenea, Acanthocephala, and Digenea. The highest prevalence and intensity of helminth parasite infection from Sunda Strait and Banten Bay were Neorhadinorhynchus sp. and Hexostoma euthynni, respectively. The number of parasites in this study was not correlated with the fish’s condition factor, total length, and total weight, nor sea surface temperature and chlorophyll-a.

Judul: Mapping of parasitic helminth infestation and zoonotic risk in marine fishes of southern Indonesian waters
Abstrak: ADHI RACHMAT SUDRAJAT HARIYADI. Mapping of parasitic helminth infestation and zoonotic risk in marine fishes of southern Indonesian waters. Under the guidance OF RISA TIURIA PRIOSOERYANTO, BAMBANG PONTJO PRIOSOERYANTO, and ETIH SUDARNIKA. This research was designed to study the differences in helminth parasitic infestation of three different fish hosts (Tuna, fusilier, and grouper). Fish samples were collected from three regions in south Indonesian waters (Sunda Strait, North Bali and East Nusa Tenggara) in order to observe geographical variations of parasitic infestations. Twenty six genera of parasitic worms from the viscera were isolated, identified, and their respective zoonotic risks were assessed. Three genera of phylum nemathelminthes, one genus from phylum plathyhelminthes, and one genus from phylum acanthocephala were identified as zoonotic parasites. Histopathological analysis of the digestive tract found that there were presence of parasites, atrophy of villi, secondary infection, as well as correlation between parasite infestation and cases of inflammation (enteritis). By mapping, level of infestation (numbers of parasites per host and numbers of parasites per gram muscle) could be used to indicate zoonotic risks in different locations. The same variable could potentially be used for indicating the amount of parasites and the presence of intermediate/paratenic/definitive hosts; thus contributing to the estimation of other marine wildlife’s health status.
