The representatives of the genus Ampelisca Krøyer, 1842 collected during the PGGOOS expedition (the Persian Gulf and Gulf of Oman Oceanographic Study) were studied. The species Ampelisca persicus sp. nov., Ampelisca lowryi sp. nov. and Ampelisca linearis sp. nov. were described. A redescription of Ampelisca cyclops Walker, 1904 was prepared based on material of the western part of the Indian Ocean. The differences between this and other records of A. cyclops were studied.

Sumberdaya ikan cakalang (Katsuwonus pelamis) merupakan ikan ekonomis penting dan utama di Indonesia. Tingginya tingkat pemanfaatan ikan cakalang di Samudra Hindia menjadi hal yang sangat rawan dan perlu kehati-hatian dalam pengelolaannya. Tersedianya data dan informasi tentang musim pemijahan merupakan bagian dari pengetahuan yang diperlukan untuk mengetahui status sumberdaya bagi upaya pengelolaannya. Penelitian ikan cakalang dilakukan berdasarkan pengambilan contoh biologi dibeberapa tempat pendaratan ikan (Palabuhan Ratu, Prigi dan Labuhan Lombok). Penelitian dilaksanakan pada bulan Januari sampai dengan Nopember 2016. Pendugaan musim pemijahan menggunakan pendekatan indeks kematangan gonad (IKG) bulanan. Distribusi ukuran ikan yang tertangkap dengan menggunakan pancing tonda berkisar antara 24 – 66 cm. Ukuran rata-rata pertama kali tertangkap (Lc) pada panjang 41,6 cm, ukuran pertama kali matang gonad (Lm) 42,5 cm. Berdasarkan fluktuasi IKG musim pemijahan ikan diduga berlangsung pada bulan April dan Nopember.Skipjack tuna (Katsuwonus pelamis) are most important and economically fish in Indonesia. The highest exploitation skipjack in the Indian Ocean is very vulnerable are requires caution in its management. The availability of data and information about the spawning season is a part of the knowledge needed to determine the status of resources for management efforts. This research was carried out based on biological sampling at several fish landing sites (Palabuhanratu, Prigi, and Labuhan Lombok). This research was conducted from January until to November 2016. Estimating of the spawning season was used a monthly Gonado Somatic Index (GSI) approach. The range of size distribution from of fish caught using troll line were 24 until 66 cm. The average size of first caught (L50%) at a length was 41.6 cm, the size of the length of first maturity (Lm) was 42,5 cm. Based on the GSI fluctuation, spawning season was done in April and November.

A New Species

Published records on the Ophiuroidea fauna of the Persian Gulf and Gulf of Oman are scattered in difficult to access journals and books. This study presents a compilation of all published records, complemented with data from new samples. Distribution, habitat and depth in the study area, as well as known Indian Ocean distributions, are included. The taxonomic status of all species was evaluated, critical comments were added as applicable, and several previous records were reassigned to other species. Ophiocoma erinaceus was removed from the fauna of the Persian Gulf and Gulf of Oman, because the only published record was instead Ophiocoma schoenleinii. Previous studies assumed that 46 species of brittle star were known from the study area, but only 38 species were confirmed by this re-assessment, including two new records (Ophiothrix (Ophiothrix) foveolata and Ophiocomella sexradia). Diagnostic features are supplied for difficult to distinguish species. Five species (Macrophiothrix elongata, Amphiura fasciata, Amphiura (Ophiopeltis) hexactis, Amphioplus echinulatus, and Amphioplus seminudus) are so far worldwide known only from the Persian Gulf area. A hexamerous, fissiparous species of Ophiothela that does not concur with any known species was found and may represent a new species. All newly collected species are illustrated with photographs.

Strike Slip Movement

Bathymetric and magnetic measurements at a 10-mile line spacing across the mouth of the Gulf of Oman have made a substantial contribution to knowledge of the area. A northeast-southwest alinement of bathymetric features, the presence of many fault scarps and the occurrence of elongated weakly magnetized seamounts similar to others farther south suggest that the Murray Ridge is continuous with the Owen fracture zone and support the idea that both are loci of strike-slip movement.

First Time

The family Macrophthalmidae Dana, 1851, is one of the best represented brachyuran groups in intertidal habitats in the Persian Gulf. Nine species from two subfamilies are reported from the gulf and the adjacent Gulf of Oman, mainly inhabiting intertidal soft substrates. The subfamily Ilyograpsinae Števcic, 2005, is represented by Ilyograpsus rhizophorae Barnard, 1950, erroneously recorded as I. paludicola (Rathbun, 1909). Eight species of the subfamily Macrophthalminae Dana, 1851, have been recorded from the area, all belonging to Macrophthalmus Desmarest, 1823. Of these, M. sinuspersici Naderloo & Türkay, 2010, has recently been described and is the only species of the genus occurring on rocky shores. Macrophthalmus graeffei A. Milne-Edwards, 1873, occurs in subtidal water and is hereby recorded for the first time from the northern Indian Ocean. The remaining six species, M. dentipes Lucas, 1836, M. depressus Rüppell, 1830, M. grandidieri A. Milne-Edwards, 1867, M. laevis A. Milne-Edwards, 1867, M. serenei Takeda & Komai, 1991, and M. sulcatus H. Milne-Edwards, 1852, are important elements of the intertidal soft bottom communities. An identification key for the genus Macrophthalmus in the area is provided, and the geographical distribution of the family is briefly discussed.
