“…Dilihat dari siklus hidupnya, beberapa jenis parasit hanya menginfeksi inang dengan memperoleh sari makanan dari darah insang inang yang dimanfaatkan untuk perkembangan telur dan berkembang biak, misalnya jenis Ergasilus sp. (Alston et al, 1996), Lernanthropus sp. (Anshary, 2016).…”

“…Jika dilihat dari siklus hidupnya, parasit dari Ergasilus sp. hanya betina yang bersifat parasitik yaitu bertelur dan berkembang pada insang inang dengan memanfaatkan sari makanan dari insang inang, kemudian setelah dewasa melepaskan diri dan berenang bebas dalam air (Alston et al, 1996). Hal ini di dukung oleh Hardi (2015) yang menjelaskan bahwa parasit Lernaeocera branchialis memakan darah atau jaringan pada insang, yang dapat menyebabkan hemoglobin ikan yang terinvestasi mengalami peradangan disertai pendarahan pada insang.…”

The Largescale mullet Liza macrolepis is a common fish found in estuaries and coastal areas and the fish is used as a source of protein by coastal communities. This study aims to analyze the prevalence and intensity of parasitic infected on mullets harvested from the waters of the West - South Aceh. This research was conducted from March to April 2019 in 8 locations, namely; Estuary Aceh River, Gampong Jawa, Banda Aceh city, Coastal Ujong Pancu, Peukan Bada, Aceh Besar, Estuary Teunom River, Calang, Aceh Jaya, Estuary, and Coastal Kuala Bubon, Samatiga, West Aceh, Estuary Nagan River Langkak Kuala Tuha Nagan Raya, Estuary, and Coastal Susoh, Blang Pidie, Southwest Aceh, Estuary and Coastal Indra Damai, Kluet Selatan, South Aceh and Estuary Sua- Sua River and Ujong Umo River, Simeulue. A total of 343 samples were examined for ectoparasites and endoparasites at the Laboratory of Hatchery, Faculty of Marine and Fisheries, Syiah Kuala University. The results showed that there were seven species of parasites, infected the mullet samples namely; Ectoparasites (Cymanthoa sp., Ergasilus sp., Lernanthropus sp., Monstriloida sp., Myxobolus sp.) and Endoparasites (Nematodes and Trematodes). Prevalence value of Kota Banda Aceh was 33% ectoparasites and 28% endoparasites), Aceh Besar was 21% ectoparasites and 15% endoparasites, Aceh Jaya was 4% ectoparasites and 4% endoparasites, Southwest Aceh was 2% ectoparasites and 2% endoparasites, Simeulue was 9% ectoparasites and 9% endoparasites. It is concluded that the higher prevalence and intensity were found in fish samples from Banda Aceh and Aceh Besar, while no fish from Nagan Raya and Aceh Selatan were infected by parasites.Keywords:ParasiteCoastalEstuaryPollutant ABSTRAKIkan belanak Liza macrolepis sering dijumpai di muara dan pesisir pantai dan dijadikan sebagai sumber protein oleh masyarakat pesisir. Saat ini belum ada penelitian terkait jenis-jenis parasite yang menyerang ikan belanak di perairan Aceh, khususnya di pantai Barat Selatan Aceh. Oleh karena itu, penelitian ini bertujuan untuk menganalisis prevelensi dan intensitas parasit pada ikan belanak di perairan Barat Selatan Aceh. Penelitian dilakukan sejak Maret sampai April 2019 meliputi 8 lokasi, yaitu; Muara Krueng Aceh, Gampong Jawa Kota Banda Aceh, Ujung Pancu, Peukan Bada Aceh Besar, Muara Krueng Teunom, Calang Aceh Jaya, Muara Sungai/Pesisir Kuala Bubon, Samatiga Aceh Barat, Muara Krueng Nagan, Kuala Tuha Nagan Raya, Muara/Pesisir Susoh, Blang Pidie Aceh Barat Daya, Muara/Pesisir Indra Damai, Kluet Selatan Aceh Selatan dan Muara sungai Ujong Umo dan muara sungai Sua – Sua, tepah barat dan Simeulu Timur, Simeulu. Metode digunakan adalah preparat ulas (Smeer method). Sebanyak 343 sampel dibedah untuk dilakukan pemeriksan ektoparasit dan endoparasit di Laborarorium Pembenihan Ikan, Fakultas Kelautan dan Perikanan, Universitas Syiah Kuala. Hasil penelitian ditemukan 7 jenis parasit, ektoparasit (Cymanthoa sp., Ergasilus sp., Lernanthropus sp., Monstriloida sp., Myxobolus sp.) dan Endoparasit (Nematoda dan Trematoda). Nilai prevalensi; Kota Banda Aceh (33% ektoparasit, 28% endoparasit), Aceh Besar (21 % ektoparasit, 15% endoparasit), Aceh Jaya (4% ektoprasit dan 4%endoparasit), Aceh Barat Daya (2% ektoprasit dan 2% endoparasit) Simeulu (9% ektoparasit dan 9% endoparasit). Disimpulkan bahwa prevelensi dan intensitas parasit tertinggi dijumpai pada sampel ikan dari Banda Aceh dan Aceh Besar, sedangkan ikan sampel dari Nagan Raya dan Aceh Selatan bebas dari serangan parasit.

“…The adult male antennule is 17-segmented (¢gure 7b) with four compound segments, XV^XVI, XIX^XX, XXI^XXIII and XXIV^XXVIII, that are not found in the female. Double-segment XV^XVI remains undivided from male CoV and in earlier stages but the three other compound (Kim & Ho 1992), Ergasilus briani (Alston et al 1996), Taeniacanthus lagocephali (Izawa 1986a) and Leptinogaster major (Humes 1986).

Comparative analysis of the development of antennulary segmentation and setation patterns across six orders of copepods revealed numerous common features. These features are combined to produce a hypothetical general model for antennulary development in the Copepoda as a whole. In this model most compound segments result from the failure of expression of articulations separating ancestral segments. In adult males, however, compound segments either side of the neocopepodan geniculation are typically formed by secondary fusion at the last moult from CoV (stage 5).The array of segments distal to the articulation separating segments XX and XXI is highly conserved both in ontogeny and phylogeny: typically the distal segmentation of the adult female is already present in the CoI. A maximum of three setae is added to the distal array during the entire copepodid phase. This morphological conservatism is interpreted as evidence of the functional continuity of the distal setal array as a mechanosensory system providing early warning of approaching predators.Sexual dimorphism typically appears late in development; the male undergoing modi¢cations especially at the ¢nal moult to sexual maturity. These modi¢cations include the formation of the neocopepodan geniculation at the XX to XXI articulation and, in some orders, the formation of a proximal geniculation at the XV to XVI articulation. A proximal geniculation is reported here from the Calanoida for the ¢rst time. The geniculations allow the male to grasp the female during any mate guarding and during spermatophore transfer. Particular setae on segments either side of the neocopepodan geniculation are modi¢ed as basally fused spines in at least some representatives of the Calanoida, Misophrioida, Cyclopoida, Harpacticoida and Siphonostomatoida.The antennulary chemosensory system, comprising primarily the aesthetascs, is enhanced at the ¢nal moult in many male copepods. In planktonic copepods this enhancement may take the form of a doubling of the aesthetascs on almost every antennulary segment, as in the eucalanid calanoids, or of an increase in size of existing aesthetascs, as in the siphonostomatoid Pontoeciella, or of the transformation of possibly originally bimodal, seta-like elements into distally thin-walled, more aesthetasc-like elements, as in some calanoids, harpacticoids and poecilostomatoids. Enhancement of the chemosensory capacity of adult males appears to be linked with their mate-locating role. Copepods inhabiting the open-pelagic water column are more likely to exhibit enhancement of the chemosensory system than neritic or benthic forms. Enhancement may confer a greater sensitivity to chemosensory signals, such as pheromones produced by receptive females, which may retain their directional information at lower concentrations and, therefore, for longer periods, in oceanic waters than in more turbulent neritic waters.Aesthetascs appear to be more evolutionarily labile than other setation elements, apparently being lost and regained within well-de¢ned lineag...
