The list is the result of regular queries in numerous journals, books and online publications. It provides a complete list of publication citations as well as a database report containing rearranged subsets of the list sorted by the keyword statistics, extant and extinct genera and species descriptions from the years 2000 to 2016, list of descriptions of extinct and extant species from 2016, parasitology, reproduction, distribution, diet, conservation, and taxonomy. The paper is intended to be consulted for information. In addition, we provide information on the geographic and depth distribution of newly described species, i.e. the type specimens from the year 1990- 2016 in a hot spot analysis. Please note that the content of this paper has been compiled to the best of our abilities based on current knowledge and practice, however, -

Nair and P.U Zacharia Central Marine Fisheries Research Institute, Kochi-682 018 Introduction eyed, stomachless, deep-sea creatures that possess an upper jaw which is fused to its cranium (unlike in sharks). The term Elasmobranchs or chondrichthyans refers to the The great majority of the commercially important species of group of marine organisms with a skeleton made of cartilage. chondrichthyans are elasmobranchs. The latter are named They include sharks, skates, rays and chimaeras.

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. -

Life-History Characteristics of the Eastern Shovelnose Ray, Aptychotrema Rostrata (Shaw, 1794), from Southern Queensland, Australia

Email: [email protected] Abstract. The eastern shovelnose ray (Aptychotrema rostrata) is a medium-sized coastal batoid endemic to the eastern coast of Australia. It is the most common elasmobranch incidentally caught in the Queensland east coast otter trawl fishery, Australia’s largest penaeid-trawl fishery. Despite this, age and growth studies on this species are lacking. The present study estimated the growth parameters and age-at-maturity for A. rostrata on the basis of sampling conducted in southern Queensland, Australia. This study showed that A. rostrata exhibits slow growth and late maturity, which are common life- history strategies among elasmobranchs. Length-at-age data were analysed within a Bayesian framework and the von Bertalanffy growth function (VBGF) best described these data. The growth parameters were estimated as L0 ¼ 193 mm À1 TL, k ¼ 0.08 year and LN ¼ 924 mm TL. Age-at-maturity was found to be 13.3 years and 10.0 years for females and males respectively. The under-sampling of larger, older individuals was overcome by using informative priors, reducing bias in the growth and maturity estimates. -

Aquatic wildmeat includes marine the cracks’ between environment and fisheries Ministries, mammals such as manatees, cetaceans and agencies and international processes. hippopotamus, reptiles such as crocodiles and marine turtles, fish (sharks and rays), and In West Africa, as worldwide, aquatic species have been aquatic birds (herons, pelicans and storks harvested for decades by local populations. Some of the most amongst others). famous human uses are (1) the trade of the hawksbill marine turtle’ shell (bekko) through Japanese networks, (2) the consumption of manatee’s or marine turtle’s meat by coastal populations and (3) the harvest of sharks for their fins for the Asian market (Miliken & Tokunaga 1987; Groombridge & Luxmoore 1989; Diop & Dossa 2011). A WIDE VARIETY OF AQUATIC SPECIES ARE THREATENED Over time, aquatic bushmeat consumption, increasing human populations and poorly enforced measures punishing the use or trade of these aquatic species, could threaten the survival of many aquatic species. -
