Histological Study of the Sex-Change in the Skunk Clownfish Amphiprion akallopisos

The Open Fish Science Journal (2009)

Margarida Casadevall Eulàlia Delgado Orphal Colleye Samuel Ber Monserrat Éric Parmentier

Sex change in the protandrous fish Amphiprion akallopisos Bleeker, 1853 (F.Pomacentridae) has been analysed.Experiments consisted of placing males together after being separated from their mates, and observe changes in gonad histology at different periods, in order to identify signs of the sex change process.The presence of a first invagination on the male gonad wall, and the observation of the first cortical alveoli oocytes as an indication of the beginning of the vitellogenesis process, was the first symptom of the sex change, which has been detected after 18 days in one of the males.Period needed for the sex changing process was size independent.The process by which wall invagination is converted into ovarian lumen in the future mature ovary is also described.

Snapshot recordings provide a first description of the acoustic signatures of deeper habitats adjacent to coral reefs of Moorea

PeerJ (2017)

Frédéric Bertucci Éric Parmentier Cécile Berthe Marc Besson A. D. Hawkins

Acoustic recording has been recognized as a valuable tool for non-intrusive monitoring of the marine environment, complementing traditional visual surveys. Acoustic surveys conducted on coral ecosystems have so far been restricted to barrier reefs and to shallow depths (10–30 m). Since they may provide refuge for coral reef organisms, the monitoring of outer reef slopes and describing of the soundscapes of deeper environment could provide insights into the characteristics of different biotopes of coral ecosystems. In this study, the acoustic features of four different habitats, with different topographies and substrates, located at different depths from 10 to 100 m, were recorded during day-time on the outer reef slope of the north Coast of Moorea Island (French Polynesia). Barrier reefs appeared to be the noisiest habitats whereas the average sound levels at other habitats decreased with their distance from the reef and with increasing depth. However, sound levels were higher than expected by propagation models, supporting that these habitats possess their own sound sources. While reef sounds are known to attract marine larvae, sounds from deeper habitats may then also have a non-negligible attractive potential, coming into play before the reef itself.

The unexploited potential of listening to deep‐sea fish

Fish and Fisheries (2020)

Marta Bolgan Éric Parmentier

Abstract Covering more than 65% of the Earth surface, the deep sea (200–11,000 m depth) is the largest biotope on Earth, yet it remains largely unexplored. The biology of its communities is still poorly understood, and many species are still to be discovered. Despite this, deep‐sea fish are already threatened by our exploitation and their conservation is hampered by a severe scarcity of data. Studies focusing on fish acoustic communication are receiving growing attention in coastal areas as they provide useful information to different fields, ranging from behaviour, ecology, wild population monitoring, biodiversity assessment, fisheries and aquaculture management. Modern non‐invasive techniques such as passive acoustic monitoring (PAM) can provide high‐resolution, long‐term and large spatial scale information on populations and ecosystem dynamics in otherwise not accessible environments. Although acoustic communication of deep‐sea fish is still poorly documented, many deep‐sea species are likely to emit sounds as they possess the required anatomical structures. Here we suggest that monitoring deep‐sea fish vocal communication might help to better understand their diversity, ecology and dynamics. Emerging technologies based on PAM have the potential to provide a holistic view of the importance of acoustic communication for deep‐sea fish and, ultimately, to inform us about essential aspects for their management and protection.

The initial response of females towards congeneric males matches the propensity to hybridise in Ophthalmotilapia

Belgian journal of zoology (2022)

Maarten Van Steenberge Noémie Jublier Loïc Kéver Sophie Gresham Sophie Derycke

Cichlid radiations often harbour closely related species with overlapping niches and distribution ranges. Such species sometimes hybridise in nature, which raises the question how they can coexist. This also holds for the Tanganyika mouthbrooders Ophthalmotilapia ventralis and O. nasuta. Earlier studies found indications of asymmetrical hybridisation with females of O. ventralis accepting males of O. nasuta, but not the other way around. We hypothesised that this was due to differences in the capacity for species recognition. Given the higher propensity of O. ventralis females towards hybridisation, we expect a reduced ability for species recognition in O. ventralis females, compared to O. nasuta females. We staged two experiments, one focusing on 22 female O. nasuta and one on 21 female O. ventralis. These fish were placed in one half of a tank and briefly exposed to a conspecific or a heterospecific male, a conspecific female, or nothing (control). Female response was evaluated by scoring six tracking parameters and by noting the occurrence of ten discrete behaviours before and during the encounter. Females always responded to the presence of another fish by approaching it. Remarkably, for both O. nasuta and O. ventralis, we did not find a different response between encounters with conspecific males and females. However, in agreement with our hypothesis, females of O. nasuta behaved differently towards conspecific or heterospecific males, whereas females of O. ventralis did not. When presented with a heterospecific male, females of O. nasuta performed a lower number of ‘ram’ behaviours. Additionally, they never displayed the ‘flee’ behaviour, a component of the species’ mating repertoire that was seen in all but one of the presentations with a conspecific male. Our findings show that differences in species recognition at first encounter predict to a large degree the outcome of the mating process, even in the absence of mating behaviour.
