First record of the batfish, Halieutopsis stellifera (Lophiiformes: Ogcocephalidae) from the eastern Indian Ocean

Siliceous planktonic species of the phyla Retaria and Cercozoa were investigated from the surface to a 200 m depth around the eastern Indian Ocean (80.00°–96.10° E, 10.08° N–6.00° S) during a 2-month cruise (10 April–13 May 2014). These species are commonly referred to as Radiolarians and are found in all of the world’s oceans; however, this is a detailed investigation of the species’ diversity in the eastern Indian Ocean. Samples were collected from the eastern Indian Ocean using a plankton towing net during a vertical haul from 44 sampling stations, which resulted in 168 taxa, including 60 species that were newly recorded in the study area. The main purpose of this work was to identify members of the phyla Retaria and Cercozoa and their distribution in the eastern Indian Ocean. The species’ morphology, identification, notes, and new geographical records are briefly described.

A New Species

Julmarichardia gutui, n. sp. is described from specimens collected in depths of 78–83 m from the Northwest Continental Shelf of Australia. Of the four previously known species of Julmarichardia Guţu, 1989, J. gutui is distinguished from J. deltoides (K. H. Barnard, 1914) and J. thomassini Guţu, 1989 by having the outer flagella of the antennule with fewer than 9 articles and its distinctive armature on anterodorsal region of the carapace. It can be separated from J. alinati Guţu, 1989 and J. bajau Bamber and Sheader, 2005 by a combination of characters, including (1) a spatulate rostrum fringed with 20 or more blunt marginal teeth interspersed with 5–8 small plumose setae; (2) distinct ridges or tubercles on the carapace, (3) a well-developed, expanded lateral lobe on article 1 of the antenna (absent in J. bajau), and (4) 3–5 blunt spines (instead of 1 or 2) on the anterior margin of the basis of pereopod 2. A key to the five nominal species now comprising the genus Julmarichardia is presented. Julmarichardia gutui represents the first record of its genus from Australian waters and the second for the genus in the eastern Indian Ocean.

The Impact

Although researchers have investigated the impact of Indian Ocean Dipole (IOD) phases on human lives, only a few have examined such impacts on fisheries. In this study, we analyzed the influence of negative (positive) IOD phases on chlorophyll a (Chl-a) concentrations as an indicator of phytoplankton biomass and small pelagic fish production in the eastern Indian Ocean (EIO) off Java. We also conducted field surveys in the EIO off Palabuhanratu Bay at the peak (October) and the end (December) of the 2019 positive IOD phase. Our findings show that the Chl-a concentration had a strong and robust association with the 2016 (2019) negative (positive) IOD phases. The negative (positive) anomalous Chl-a concentration in the EIO off Java associated with the negative (positive) IOD phase induced strong downwelling (upwelling), leading to the preponderant decrease (increase) in small pelagic fish production in the EIO off Java.
