Última Ecologie et cartographie des coraux d’eau froide du canyon de Lacaze-Duthiers en Méditerranée; Données de la campagne CALADU 2019 ArchiMer Sanchez, Pierre; Fabri, Marie-claire. This work aimed to study populations of cold-water corals in the Lacaze-Duthiers canyon, a French canyon in the western part of the Gulf of Lion. the study was carried out using photos and videos of the wire-Remote Operated Vehicle: the HROV Ariane. Analysis of photos and videos allowed us to obtain information on the general biodiversity, on the spatial and vertical distribution and on the population density of the coldwater coral communities of the canyon but also on the size ranges and of colors of these species. Thus, it was noted that Madrepora oculata was the most represented species. This species has been observed in abundance ten times greater than the Lophelia pertusa species, which presented very dense distributions in places and then almost...

Individual tagging is key to a better understanding of early life stages in fish. Very small RFID transponder microchips (500 × 500 × 100 μm, 82 μg) are now available. The aim of this study was to develop a protocol to tag European sea bass (Dicentrarchus labrax L.) larvae from 61 days post-hatching (dph; standard length ~10 mm) to 96 dph (standard length ~28 mm) through intra-coelomic implantation of microchips. The suitability of such a tagging procedure was evaluated, with the purpose of determining the minimal fish age and body size for microchip tagging without adverse effects on survival and growth performance. We produced an experimental population composed by 50:50 normally pigmented larvae and albino larvae through artificial fertilization. Five...

The European sea bass (Dicentrarchus labrax) exhibits female-biased sexual size dimorphism (SSD) early in development. New tagging techniques provide the opportunity to monitor individual sex-related growth during the post-larval and juvenile stages. We produced an experimental population through artificial fertilization and followed a rearing-temperature protocol (~16°C from hatching to 112 days post-hatching, dph; ~20°C from 117 to 358 dph) targeting a roughly balanced sex ratio. The fish were tagged with microchips between 61 and 96 dph in five tagging trials of 50 fish each; individual standard length (SL) was recorded through repeated biometric measurements performed between 83 to 110 dph via image analyses. Body weight (BW) was modelled using the... Tipo: Text Ano: 2021 URL: https://archimer.ifremer.fr/doc/00691/80288/83391.pdf Registros recuperados: 3 Primeira ... 1 ... Última
