And Giant Guitarfish (Rhynchobatus Djiddensis)
VIRAL DISCOVERY IN BLUEGILL SUNFISH (LEPOMIS MACROCHIRUS) AND GIANT GUITARFISH (RHYNCHOBATUS DJIDDENSIS) BY HISTOPATHOLOGY EVALUATION, METAGENOMIC ANALYSIS AND NEXT GENERATION SEQUENCING by JENNIFER ANNE DILL (Under the Direction of Alvin Camus) ABSTRACT The rapid growth of aquaculture production and international trade in live fish has led to the emergence of many new diseases. The introduction of novel disease agents can result in significant economic losses, as well as threats to vulnerable wild fish populations. Losses are often exacerbated by a lack of agent identification, delay in the development of diagnostic tools and poor knowledge of host range and susceptibility. Examples in bluegill sunfish (Lepomis macrochirus) and the giant guitarfish (Rhynchobatus djiddensis) will be discussed here. Bluegill are popular freshwater game fish, native to eastern North America, living in shallow lakes, ponds, and slow moving waterways. Bluegill experiencing epizootics of proliferative lip and skin lesions, characterized by epidermal hyperplasia, papillomas, and rarely squamous cell carcinoma, were investigated in two isolated poopulations. Next generation genomic sequencing revealed partial DNA sequences of an endogenous retrovirus and the entire circular genome of a novel hepadnavirus. Giant Guitarfish, a rajiform elasmobranch listed as ‘vulnerable’ on the IUCN Red List, are found in the tropical Western Indian Ocean. Proliferative skin lesions were observed on the ventrum and caudal fin of a juvenile male quarantined at a public aquarium following international shipment. Histologically, lesions consisted of papillomatous epidermal hyperplasia with myriad large, amphophilic, intranuclear inclusions. Deep sequencing and metagenomic analysis produced the complete genomes of two novel DNA viruses, a typical polyomavirus and a second unclassified virus with a 20 kb genome tentatively named Colossomavirus. -

Alloparental care in clownfishes Binu Varghese Marine Products Exports Development Authority, Kochi, India Parental care in clownfishes is well known, mouthing and fanning are the important behaviours apart from defending eggs from predators. They fan the egg mass using pectoral and caudal fins and thus provide necessary water movement to the densely packed clutch and thus help in faster removal of metabolic wastes (Figure 1). Clownfishes also remove unfertilized and unhealthy eggs from the clutch (egg batch). -
New Fossils of Cichlids from the Miocene of Kenya and Clupeids from the Miocene of Greece (Teleostei)
The importance of articulated skeletons in the identification of extinct taxa: new fossils of cichlids from the Miocene of Kenya and clupeids from the Miocene of Greece (Teleostei) Dissertation zur Erlangung des Doktorgrades an der Fakultät für Geowissenschaften der Ludwig-Maximilians-Universität München Vorgelegt von Charalampos Kevrekidis München, 28.

Furthermore, I certify that this work contains no material which has been accepted for the award of any other degree or diploma in my name, in any university and, to the best of my knowledge and belief, contains no material previously published or written by another person, except where due reference has been made in the text. In addition, I certify that no part of this work will, in the future, be used in a submission in my name, for any other degree or diploma in any university or other tertiary institution without the prior approval of the Ludwig-Maximilians-Universität München. München, 21.09.2020 Charalampos Kevrekidis 3 Abstract Fishes are important components of aquatic faunas, but our knowledge on the fossil record of some taxa, relative to their present diversity, remains poor. This can be due to a rarity of such fossils, as is the case for the family Cichlidae (cichlids). Another impediment is the rarity of well-preserved skeletons of fossil fishes. -

Effect of increased temperature and decreased food quality on metabolism and growth of an algivorous cichlid, Tropheus duboisi, and effect of food habit on the field metabolism of African Cichlids. The metabolic rate of an organism is influenced by mass, temperature, and diet. Climate change is anticipated to increase ambient temperatures of aquatic systems and decrease the quality of food available to algivorous fish.
