ABSTRAKPenelitian ini bertujuan untuk mengetahui karakteristik morfometrik dan meristik ikan julung-julung di Teluk Ekas, Lombok Timur. Sampel penelitian berjumlah 165 ikan yang di tangkap pada daerah intertidal dengan metode swept area menggunakan pukat pantai (beach seine) di tiga stasiun. Karakteristik morfologi yang terlihat dengan jelas pada ikan julung-julung ini yaitu memiliki rahang bawah dengan warna merah pada ujungnya dan memiliki ukuran yang jauh lebih panjang jika dibandingkan dengan rahang atasnya. Hasil pengukuran karakteristik morfometrik menunjukkan bahwa ikan julung-julung yang terdapat pada daerah intertidal perairan Teluk Ekas merupakan ikan muda (juvenile) dengan frekuensi panjang total (PT) tertinggi terdapat pada ukuran 13,1-15 cm. Kesimpulan dari penelitian ini menunjukkan bahwa ikan julung-julung di daerah intertidal Teluk Ekas memiliki karakteristik morfometrik yang hampir sama dengan ikan julung-julung pada umumnya. Kata-kata kunci: Ikan Julung-Julung, Karakteristik, Meristik, Morfometrik   ABSTRACT This research intended to know the morphometric and meristic characteristic of jumping halfbeak at Ekas Bay, East Lombok. The sample of this research consisted of 165 fishes which caught at intertidal zone using swept area method with beach seine in three stations. The morphological characteristic which can be seen clearly on jumping halfbeak has lower jaw with red tip and longer than its upper jaw. The results of measurement of morphometric characteristic proved that jumping halfbeak at intertidal zone of Ekas Bay were young fish (juvenile) total length highest frequency on range of 13,1-15 cm. The conclusion of this research is jumping halfbeak at the intertidal zone of Ekas Bay has the similar characteristic morphometric to the general one. Keywords: Characteristic, Jumping halfbeak, Meristic, Morphometric

Abstract The Pacific saury (Cololabis saira) is a fish of commercial importance subject to unpredictable epidemics of infection by Pennella sp., a parasitic copepod. We analyzed the distribution of fish presenting with newly attached Pennella to determine the region and season in which Pennella first infect the fish. Pacific sauries migrate northward in the spring to spend the summer in the subarctic region, successively crossing the Subarctic Boundary (SAB) and the Subarctic Front (SAF). The fish then return to subtropical waters in the fall and overwinter there. Pacific sauries infected with Pennella were observed on both the north and south sides of the SAF from May to December. Newly attached Pennella, however, were observed mainly to the south of the SAF during the northward migration of the fish in May and June, and only to the south of the SAB during the southward migration in November and December. These results indicate that the intermediate host or hosts of Pennella inhabit the region south of the SAF, with infection of Pacific saury occurring during late fall and spring. Such information may assist in identifying the intermediate host(s).
