Breaking with Tradition: Redefining Measures for Diet Description with a Case Study of the Aleutian Skate Bathyraja Aleutica (Gilbert 1896)

Spatial Ecology and Fisheries Interactions of Rajidae in the Uk
UNIVERSITY OF SOUTHAMPTON FACULTY OF NATURAL AND ENVIRONMENTAL SCIENCES Ocean and Earth Sciences SPATIAL ECOLOGY AND FISHERIES INTERACTIONS OF RAJIDAE IN THE UK Samantha Jane Simpson Thesis for the degree of DOCTOR OF PHILOSOPHY APRIL 2018 UNIVERSITY OF SOUTHAMPTON 1 2 UNIVERSITY OF SOUTHAMPTON ABSTRACT FACULTY OF NATURAL AND ENVIRONMENTAL SCIENCES Ocean and Earth Sciences Doctor of Philosophy FINE-SCALE SPATIAL ECOLOGY AND FISHERIES INTERACTIONS OF RAJIDAE IN UK WATERS by Samantha Jane Simpson The spatial occurrence of a species is a fundamental part of its ecology, playing a role in shaping the evolution of its life history, driving population level processes and species interactions. Within this spatial occurrence, species may show a tendency to occupy areas with particular abiotic or biotic factors, known as a habitat association. In addition some species have the capacity to select preferred habitat at a particular time and, when species are sympatric, resource partitioning can allow their coexistence and reduce competition among them. The Rajidae (skate) are cryptic benthic mesopredators, which bury in the sediment for extended periods of time with some species inhabiting turbid coastal waters in higher latitudes. Consequently, identifying skate fine-scale spatial ecology is challenging and has lacked detailed study, despite them being commercially important species in the UK, as well as being at risk of population decline due to overfishing. This research aimed to examine the fine-scale spatial occurrence, habitat selection and resource partitioning among the four skates across a coastal area off Plymouth, UK, in the western English Channel. In addition, I investigated the interaction of Rajidae with commercial fisheries to determine if interactions between species were different and whether existing management measures are effective. -

Identification Guide to the Deep-Sea Cartilaginous Fishes Of
Identification guide to the deep–sea cartilaginous fishes of the Southeastern Atlantic Ocean FAO. 2015. Identification guide to the deep–sea cartilaginous fishes of the Southeastern Atlantic Ocean. FishFinder Programme, by Ebert, D.A. and Mostarda, E., Rome, Italy. Supervision: Merete Tandstad, Jessica Sanders (FAO, Rome) Technical editor: Edoardo Mostarda (FAO, Rome) Colour illustrations, cover and graphic design: Emanuela D’Antoni (FAO, Rome) This guide was prepared under the “FAO Deep–sea Fisheries Programme” thanks to a generous funding from the Government of Norway (Support to the implementation of the International Guidelines on the Management of Deep-Sea Fisheries in the High Seas project) for the purpose of assisting states, institutions, the fishing industry and RFMO/As in the implementation of FAO International Guidelines for the Management of Deep-sea Fisheries in the High Seas. It was developed in close collaboration with the FishFinder Programme of the Marine and Inland Fisheries Branch, Fisheries Department, Food and Agriculture Organization of the United Nations (FAO). The present guide covers the deep–sea Southeastern Atlantic Ocean and that portion of Southwestern Indian Ocean from 18°42’E to 30°00’E (FAO Fishing Area 47). It includes a selection of cartilaginous fish species of major, moderate and minor importance to fisheries as well as those of doubtful or potential use to fisheries. It also covers those little known species that may be of research, educational, and ecological importance. In this region, the deep–sea chondrichthyan fauna is currently represented by 50 shark, 20 batoid and 8 chimaera species. This guide includes full species accounts for 37 shark, 9 batoid and 4 chimaera species selected as being the more difficult to identify and/or commonly caught. -

Recent Contributions to the Knowledge of the Skates of Alaska by Duane E
FEATURE Recent Contributions to the Knowledge of the Skates of Alaska by Duane E. Stevenson and James W. Orr Figure 1. Raja binoculata (big skate). Photo by Duane Stevenson. he fish family Rajidae, commonly known imately 30 species worldwide and a North Pacific as the skates, includes about 280 species of assemblage of 6 species ranging from the Gulf of primarily benthic fishes found throughout California to the Bering Sea and into the western Tthe world’s oceans from tropical to cold temperate North Pacific. This North Pacific Assemblage is latitudes. The fishes of Alaska (Mecklenburg et al., thought to be a cluster of closely related species and 2002), the most recent inventory of Alaska’s fishes, will probably be recognized as a separate genus in lists 12 species of skates known to occur in the Gulf the future. The genus Bathyraja, also known as the of Alaska, Aleutian Islands, and Bering Sea from “soft-snout” skates due to their flexible rostral car- the intertidal zone to depths of over 1500 m, and tilage, includes over 40 species distributed through- at least 2 other species have been discovered in the out the world’s oceans. Bathyraja is the most broadly region since the publication of that volume as de- distributed as well as the most diverse of all the scribed in Bathyraja mariposa: a new species of skate skate genera, and the greatest diversity of Bathyraja (Rajidae: Arhynchobatinae) from the Aleutian Islands occurs in the North Pacific. The majority of Alaska’s (Stevenson et al., 2004a) and New records of two deep- skate species are included in this genus, although water skate species from the Bering Sea (Stevenson and some authors include one or two of the species in Orr, submitted). -

As a first step towards credible conservation actions for the Arctic marine fish faunae, we examine the species-richness of chondrich- thyan fishes (class Chondrichthyes) pertaining to 16 regions within the AOAS: chimaeras, sharks and skates. CHONDRICHTHYAN materials and methods • Voucher specimens from Natural History Collections IN THE ARCTIC OCEAN • Annotated checklists (see selected references) • The CAFF Database on Arctic marine fishes (Christiansen et al., in AND ADJACENT SEAS progress) FISHES Only presence and absence data are considered, as reliable abundance data lack for most species. Occurrences known only from floating or beach-cast carcasses, such as Pacific sleeper shark (no. 17) and Alaska skate (no. 29) in the Chukchi Sea, are not considered conclusive evidence of presence and are not included.
