Elasmobranchs are critical to tourism industries worldwide. In French Polynesia, where ecotourism is the second most important industry, little is known about the spatiotemporal distribution of eagle rays. This study represents the first investigation into habitat use and behaviour of ocellated eagle rays (Aetobatus ocellatus) in French Polynesia focused on two sites with different levels of anthropogenic noise. Environmental variables and biological data were recorded over a one-year period to explore the distribution patterns of...

First record of the copperstriped cardinalfish Ostorhinchus holotaenia (Actinopterygii: Perciformes: Apogonidae) from Toamasina, Madagascar

Mathieu Pinault, Julien Wickel & Ronald Fricke
This paper reports the first record of the species Ostorhinchus holotaenia Regan, 1905 from Madagascar. This species was identified during a survey of marine introduced species, carried out in June 2018 in and close to the port of Toamasina, on behalf of the Indian Ocean Commission. However, although the question of a possible introduction of the species by maritime traffic may be raised, this observation is probably more of a range extension of the species,...

Selectivity on epilithic diatom consumption for two tropical sympatric gobies: Sicydium punctatum Perugia, 1986 and Sicydium plumieri (Bloch, 1786)

Dominique Monti, Estelle Lefrançois, Clara Lord, Jean-Michel Mortillaro, Pascal Jean Lopez & Philippe Keith
Rivers of the Caribbean islands harbour a freshwater fauna mainly constituted of migrant diadromous species. In these hyperturbulent ecosystems, the primary producers are mostly represented by a thin epilithic biofilm, mainly composed of diatoms. Comparison of the diatoms available from the environment with the ones consumed and located in the digestive tracts of two gobiid fish, Sicydium punctatum Perugia, 1896 and Sicydium plumieri (Bloch, 1786) were made at twelve sampling locations, located upstream or downstream...

First record of five fish species from Réunion Island observed during the inventory of the Marine Natural Zones of Interest for Ecology, Flora and Fauna (ZNIEFF)

Mathieu Pinault, Julien Wickel, Thierry Mulochau, Jean-Benoît Nicet & Ronald Fricke
This paper reports the first record of five species of marine fishes from Reunion Island, identified during biodiversity surveys carried out within the framework of the Marine Natural Zones of Interest for Ecology, Flora and Fauna (ZNIEFF). These species: Fusigobius inframaculatus(Randall, 1994), Fusigobius neophytus(Günther, 1877), Samariscus triocellatusWoods, 1960, Trichonotus marleyi(Smith, 1936) and Zapogon evermanni(Jordan and Snyder, 1904) were all photographed within non-reef habitats, despite the sampling of many reef and non-reef habitats of the island...

Are mangroves important for reef fish on Mayotte Island (Indian Ocean)?

Rakamaly Madi Moussa
In order to understand the potential role of the mangroves of Mayotte Island for reef fishes, sampling was conducted monthly from April 2016 to April 2017 in three sites along a mangrove fringe: Bandrélé near fringing reef, Dzoumogné close to a river mouth and Malamani in a bay. Fishes were sampled using a fyke-net combined with visual census surveys (UVC) and eight environmental variables were recorded at each site to determine their relationship with the...

The post-embryonic development of Amphiprion perideraion reveals a decoupling between morphological and pigmentation change

Pauline Salis, Natacha Roux, David Lecchini & Vincent Laudet
During coral reef fish life cycle, the young pelagic larvae colonize the reef. During such important ecological transition, larvae undergo metamorphosis consisting on important morphological, colour, physiological and behavioural changes. We investigated the post-embryonic development of Amphiprion perideraion Bleeker, 1855 larvae raised in captivity from 1 day post-hatching (dph) until 20 dph. To do so, we characterized larval growth, morphological changes and pigmentation ontogenesis. Interestingly, whereas most of the morphological changes are done from 3...

A first record of the vanishing silhouette goby Silhouettea evanida (Gobiidae) in Indonesian waters

Muhammad Iqbal, Doni Setiawan, Riza Kadarisman, Arum Setiawan & Indra Yustian
In April 2017, some individuals of the vanishing silhouette goby Silhouettea evanida were identified and photographed in the estuary of the Sembilang River, South Sumatra province, Indonesia. There is no previous report on the occurrence of Silhouettea evanidain Indonesia, and this observation constitutes a first record for the country.

A juvenile Stereolepis doederleini (Polyprionidae) from a tidal pool at Jeju Island, Korea

Hyuck Joon Kwun, Jinsoon Park, Hye-Seon Kim, Ju-Hee Kim & Hyo-Seon Park
We report the first finding of a juvenile striped jewfish (Stereolepis doederleini) from Jeju Island, Korea, collected from a tidal pool on 11 May 2017. The specimen was characterized on the basis of its black head and body, the posterior tip of the maxilla beyond the middle of the eye, the posterior tip of the pelvic fin reaching the anus, dorsal fin with 11 spines and 10 soft rays, and anal fin with 3 spines...

First record of the southwestern Indian Ocean endemic Apolemichthys kingi (Teleostei: Pomacanthidae) from Sainte Marie Island, Madagascar

Julien Wickel, Luciano Landry Toto, Mathieu Pinault, Ronald Fricke & Dominique Ponton
Known to date as an endemic species of the border area between South Africa and Mozambique, Apolemichthys kingiis reported for the first time from the northeast coast of Madagascar (Sainte-Marie Island) at 34 m deep. The presence of this species in Madagascar was corroborated by the record in the BOLD database of a specimen with similar morphology, captured in 2013 on the southeast coast of Madagascar (Fort Dauphin). These observations confirm the range extension of...

First record of the near threatened native seahorse Hippocampus reidi (Teleostei: Syngnathidae) in an ecosystem dominated by the invasive seagrass Halophila stipulacea in the Caribbean Sea

Mathieu Pinault, Julien Wickel, Jean-Benoît Nicet, Marc Chenoz, Benjamin de Montgolfier & Ronald Fricke
A specimen of the Longsnout seahorse (Hippocampus reidi) was photographed in a seagrass bed dominated by the invasive species Halophila stipulacea at 11 m depth, on 9thJune 2017, in front of the Madiana Beach, Schœlcher, Martinique Island, Caribbean Sea. This short communication reports the first observation of H. reidiin this exotic ecosystem.

Effect of environmental change after the 2011 tsunami on the population dynamics of Japanese tubesnout Aulichthys japonicus (Gasterosteiformes)

Go Katayose & Takashi Asahida
The Japanese tubesnout Aulichthys japonicus Brevoort, 1862 is a small fish species, which lives in shallow coastal waters, especially in seagrass (Zostera spp.) beds. The fish is known for their unusual spawning behaviour of concealing their eggs in ascidians (Halocynthia roretzi). By studying the larval and juvenile fish fauna in a seagrass bed in southern Iwate, Japan since 2007, we observed that A. japonicus was a dominant species. On 11 March 2011, the seagrass bed...

What can goby otolith morphology tell us?

Christoph Gierl, Dorothea Liebl, Radek Šanda, Jasna Vukić, Hamid Reza Esmaeili & Bettina Reichenbacher
The taxonomic information inscribed in otoliths has been widely ignored in ichthyological research, especially in descriptions of new fish species. One reason for this is that otolith descriptions are per se qualitative, and only a few studies have presented quantitative data that can support assignments of otoliths to individual species or permit differentiation between higher taxonomic levels. On the other hand, in palaeontology, otoliths have been employed for the identification and taxonomic placement of fossil...

First record of Nanobagrus armatus (Siluriformes: Bagridae) in Sumatra, Indonesia

Doni Setiawan, Ajiman & Muhammad Iqbal
On March 2017, a specimen of Nanobagrus armatus was captured and photographed in the Keroh River, South Sumatra province. So far, N. armatus has only been observed from Indonesian Borneo, so this record constitutes the first record of this species for Sumatra.

Temporal dynamics of the recruitment of glass eels in two valleys of French Polynesia (Tahiti and Moorea Islands)

Herehia Helme, Frédéric Bertucci, Rakamaly Madi Moussa, Yann Wolff & Pierre Sasal
Glass eels were sampled in two estuaries of French Polynesia (Tahiti and Moorea islands) from 2009 to 2017. Three species were identified by morphological measurements (Anguilla marmorata, A. megastoma and A. obscura). Our results revealed a difference in the species composition between Moorea and Tahiti. The recruitment of eels is seasonal and occurs between November and March during the rainy season, with peaks in December and January. The recruitment size of glass eels was analyzed...
