7th International Workshop on the Biology of Fish Gametes 3-6 Sept. 2019, Rennes, France Book of abstracts Printed in Rennes, France, August 2019 Editors: Alexandra Depincé, Audrey Laurent Cover design: Eric Beaumont, Alexandra Depincé, Audrey Laurent Crédit photo : INRA-Didier Marie (œufs) Edition: 1st 7th International Workshop on the Biology of Fish Gametes - 2019, Rennes, France 3 7th International Workshop on the Biology of Fish Gametes - 2019, Rennes, France 4 WELCOME ADDRESS Dear participants to the 7th International Workshop on the Biology of Fish Gametes We are happy to welcome you this year, for the 7th edition of this biennial workshop initiated in 2007 by Otomar Linhart and his colleagues in Vodňany. Before these workshops, which have now become a tradition, the oldest among us may remember the single Workshop on Gamete and Embryo Storage and Cryopreservation in Aquatic Organisms held in 1992 in Marly le Roy, near Paris. The organizer was Professor Roland Billard, who had imagined with Jacky Cosson, Christian Fauvel, Gérard Maisse and Maurice Loir that the aquatic research community should meet and share knowledge and future directions. This is where we could for the first time put faces on the names of E. Kopeika, O. Linhart, A. Ciereszko, E. Lubzens, F. Lahnsteiner, M. Suquet, T. Zhang, O. Chereguini or N.H. Chao. We could not have imagined that so many years later, this community would have expanded to where we are today, and would have become this closely linked community, held by shared research interests and true friendship. Roland passed away last March. This meeting will be an opportunity for the oldest to remember, and for the youngest to get to know the exceptional researcher Roland Billard was. He paved the way for most of our research on the biology of fish gametes. Jacky Cosson agreed to do an obituary for Roland, and we are grateful to him for that. You came from 16 countries to give and share together the presentation of 34 oral and 66 poster communications. You made the program thanks to your proposals, which the local scientific committee organized in sessions dedicated to I. Spermatogenesis and Sperm Quality, II. Germinal Stem Cells and Biotechnologies, III. Refrigeration and Cryopreservation, IV. Oogenesis and Egg Quality, and V. Sperm Motility and Fertilization. It is noteworthy that our research interests are gradually shifting from gametes to germline stem cells. As a whole, our community is developing research that spans from sperm cryopreservation and germline stem cell transplantation to crispr/cas9 genome editing and gamete proteomics, together with studies on gamete interactions and motility mechanisms. We are pleased that more than 30 students are participating to the student prize competition that IMV Technologies is sponsoring this year. We are also pleased that IMV initiated a partnership with the Workshop on Biology of Fish Gametes, with the intention of sponsoring the workshop for at least two more editions. This will be a great help to our research community. We hope you will enjoy your stay in Rennes, and that you will enjoy the whole meeting on the beautiful AgroCampus site. A very enthusiastic local group from INRA LPGP took care of thousands of small details to make everything work as well as possible, we hope. And if you are here, it is because you have passed a very demanding test: registration on our website. So you all succeeded, congratulations, everything that can happen next will seem easy and smooth to you. Good workshop, good science.

Kullander* Danio flagrans, new species, is described from headwaters of the Mali Hka River in the vicinity of Putao in north- ern Myanmar. It is distinguished from D. choprae by longer barbels, longer caudal peduncle, shorter anal-fin base, more caudal vertebrae, fewer anal-fin rays, short vs. usually absent lateral line, details of the colour pattern, and mitochondrial DNA sequences. The two species share a unique colour pattern combining dark vertical bars an- teriorly on the side with dark horizontal stripes postabdominally, and brilliant red or orange interstripes anteri- orly and posteriorly on the side. Pointed tubercles on the infraorbital bones are observed in both species, but were found to be mostly present and prominent in D. choprae and mostly absent in D. flagrans, and are considered as possibly being seasonal in expression. Danio choprae is known from three localities along the Mogaung Chaung southwest of Myitkyina.

Kullander* Danio dangila is widely distributed in the Ganga and lower Brahmaputra basins of India, Nepal and Bangladesh and distinguished by the cleithral spot in the shape of a short vertical stripe (vs. a round spot in all similar spe- cies). Four new species are described, similar to D. dangila but with round cleithral spot and each diagnosed by species specific colour pattern. Danio assamila, new species, is reported from the upper and middle Brahmaputra drainage in India. Danio catenatus, new species, and D. concatenatus, new species, occur in rivers of the western slope of the Rakhine Yoma, Myanmar. Danio sysphigmatus, new species, occurs in the Sittaung drainage and small coastal drainages in southeastern Myanmar. Those five species, collectively referred to as chain danios, make up a distinctive group within Danio, diagnosed by elevated number of unbranched dorsal-fin rays, long rostral and maxillary barbels, complete lateral line, presence of a prominent cleithral spot, horizontal stripes modified into series of rings formed by vertical bars between horizontal dark stripes, and pectoral and pelvic fins each with the unbranched first ray prolonged and reaching well beyond the rest of the fin. Danio meghalayensis is resurrected from the synonymy of D. dangila, with D. deyi as a probable junior synonym. Danio meghalayensis has a colour pattern similar to that of chain danios with vertical bars bridging parallel horizontal stripes but usually pre- dominantly stripes instead of series of rings, a smaller cleithral spot and shorter barbels, and the unbranched ray in the pectoral and pelvic fins is not prolonged.

E-mail: [email protected] Abstract Danio feegradei Hora is redescribed based on recently collected specimens from small coastal streams on the western slope of the Rakhine Yoma, ranging from the Thade River drainage southward to slightly north of Kyeintali. Danio ab- sconditus, new species, is described from the Kyeintali Chaung and small coastal streams near Gwa, south of the range of D. feegradei. Both species are distinguished from other Danio by the presence of a dark, elongate or round spot at the base of the caudal fin and a cleithral marking composed of a small black spot margined by a much smaller orange spot. Danio feegradei is characterized by the colour pattern, with series of white spots along the otherwise dark side; D. absconditus by about 7–11 dark vertical bars on the abdominal side. Within Danio, the presence of a complete lateral line, cleithral spot, and 14 circumpeduncular scales is shared with D.

    Evolution of the Potassium Channel Gene Kcnj13 Underlies Colour Pattern Diversification in Danio fish

    ARTICLE https://doi.org/10.1038/s41467-020-20021-6 OPEN Evolution of the potassium channel gene Kcnj13 underlies colour pattern diversification in Danio fish Marco Podobnik 1, Hans Georg Frohnhöfer1, Christopher M. Dooley1,2, Anastasia Eskova1,3, ✉ Christiane Nüsslein-Volhard1 & Uwe Irion 1 The genetic basis of morphological variation provides a major topic in evolutionary devel- opmental biology. Fish of the genus Danio display colour patterns ranging from horizontal 1234567890():,; stripes, to vertical bars or spots. Stripe formation in zebrafish, Danio rerio, is a self-organizing process based on cell−contact mediated interactions between three types of chromato- phores with a leading role of iridophores. Here we investigate genes known to regulate chromatophore interactions in zebrafish that might have evolved to produce a pattern of vertical bars in its sibling species, Danio aesculapii. Mutant D. aesculapii indicate a lower complexity in chromatophore interactions and a minor role of iridophores in patterning. Reciprocal hemizygosity tests identify the potassium channel gene obelix/Kcnj13 as evolved between the two species. Complementation tests suggest evolutionary change through divergence in Kcnj13 function in two additional Danio species. Thus, our results point towards repeated and independent evolution of this gene during colour pattern diversification. 1 Max Planck Institute for Developmental Biology, Max-Planck-Ring 5, 72076 Tübingen, Germany. 2Present address: Max Planck Institute for Heart and Lung Research, Ludwigstrasse 43,

Abstract Animal pigment patterns play important roles in behavior and, in many species, red coloration serves as an honest signal of individual quality in mate choice. Among Danio fishes, some species develop erythrophores, pigment cells that contain red ketocarotenoids, whereas other species, like zebrafish (D. rerio) only have yellow xanthophores.

To understand the history of these species and how they acquired the genetic differences underlying their diverse phenotypes, I performed two phylogenomic studies using Restriction-Site Associated DNA Sequencing and DNA hybridization-based exome enrichment. The results of these studies highlight important methodological considerations applicable to future experiments across taxa. Furthermore, these studies provide detailed understanding of the relationships within Danio including extensive introgression between lineages. The extent of introgression varies across the genome with regions of high recombination at the ends of chromosomes having the most evidence for introgression.

Here, we argue that the use of indeterminate-growing teleost fish in Encarnación Capilla, University of Barcelona, Spain skeletal muscle aging research may lead to therapeutic advancements not possible with Alessandro Cellerino, Scuola Normale current mammalian models. Evidence from a comparative approach utilizing the subfamily Superiore, Italy Danioninae suggests that the indeterminate growth paradigm of many teleosts arises *Correspondence: from adult muscle stem cells with greater proliferative capacity, even in spite of smaller Peggy R. Biga, Department of Biology, progenitor populations. We hypothesize that paired-box transcription factors, Pax3/7, are University of Alabama at Birmingham, 1300 University Boulevard CH464, involved with this enhanced self-renewal and that prolonged expression of these factors Birmingham, AL 35294-1170, USA may allow some fish species to escape, or at least forestall, sarcopenia/dynapenia.
