Identificaton of grouper parasites (Epinephelus coioides) in Talawi District, Batubara Regency

Abstract

Batu Bara Regency is a region with abundant natural resources, one of which is the cultivation of grouper fish. Grouper is a member of the Serranidae family of coral reef fish. Many groupers are raised in ponds, which makes them susceptible to disease due to environmental and dietary factors that are not adapted to grouper fish, which is a native species. Parasites are one of the grouper-infecting diseases that, if left untreated, can result in mass mortality and harm farmers. The aim of this study was to identify parasites in ponds in Mesjid Lama Village, Talawi District, so that it would be easier to determine the type of parasite, its level of attack, and subsequent efforts to eradicate it. This research employs a sampling technique, specifically a random sampling of orange-spotted grouper. The results of the performed analysis include analyses of both ectoparasites and endoparasites. Several types of ectoparasites were identified, including Cryptocaryon irritans, Pseudorhabdosynochus sp, Benedenia epinepheli, and Caligus sp, while Prosorynchus sp was identified as the endoparasite. The most prevalent parasite found in the fish is Cryptocaryon irritans.Keywords: EndoparasiteParasitesGrouper

First microphological and molecular parasitological survey of Benedenia in humpback grouper (Cromileptes altivelis) of Lampung and Situbondo, Indonesia

“…Moreover, B. epinephelii also had a pair of antennae at the front and a haptor at the back (Rumondang et al 2022). B. epinepheli is a skin worm parasite from the Platyhelminthes phylum, Trematoda Monogenea class, and the genus Benedenia (Jithendran et al 2005).…”

“…This parasite is reported to attack humpback groupers in Indonesia (Sudewa et al 2020;Subekti et al 2021). This parasite even attacks other grouper species, such as Epinephelus spp., Epinephelus coioides Hamilton, 1822, and even hybrid grouper (Epinephelus fuscoguttatus x Epinephelus lanceolatus) (Lestari et al 2020;Fusianto et al 2021;Rumondang 2022). Benedenia is quite dangerous because it is often reported with secondary diseases such as viruses and bacteria that cause mortality (Turgay et al 2019;Fusianto 2021).…”

Financial Feasibility Analysis of llisha elongata Cracker Processing Businesses at Fish Processing Unit in Bengkalis, Riau

“…= Rp.9.599.700,-x 100% = 57,66% Rp. 16.650.300,-Profitability is the ability of a business with the Capital that works in it to generate profits in a certain period. The results of the profitability of the fish cracker processing business obtained a profit of 57.66% of the Capital spent on operational activities.This 57.66% retability can be interpreted that every time there is an addition of 100 rupiah, the UPI processing business will generate a profit of 57.66 rupiah.…”

“…The puput fish, scientifically known as Ilisha elongata, is a pelagic fish with considerable economic value due to its high protein content of 77.46% [16]. Characterized by cycloid-like scales, a torpedo-shaped body, a beard and fish-like mouth, a fork-shaped tail, and fins, the puput fish inhabits brackish and coastal waters.…”
