Bycatch of skates (Elasmobranchii: Arhynchobatidae, Rajidae) in the Patagonian red shrimp fishery
Fisheries Research, 2005Abstract Landings of batoids (rays and skates) have been rising in Argentina, reaching 14 856 mt in 1998. These species are poorly known, and their low fecundity, late maturity and slow growth rates make them vulnerable to stock collapse even when subjected to low levels of fishing pressure.

First information on the Arctoraja sexoculata frequency of occurrence, ecology, and biology, from the area off the middle Kuril Islands has been provided. It is estimated that the Arctoraja sexoculata is a common bycatch species in trawl fishing for the commander squid Berryteuthis magister in this water area.

The results of long-term studies of fishing catch dynamics, biomass and size composition of stingrays off the western coast of Kamchatka from 1980 to 2019 are presented. As we show, in recent years the largest part of stingrays has been caught in the Kamchatka-Kurilskaya subzone.

Oviparous elasmobranch embryos (Chondrichthyes) have been the focus of several embryological studies; they are useful models for studying early ontogeny in vertebrates, as can help explore the existence of common developmental patterns among species. Skates (Rajiformes) are the most speciose order of oviparous elasmobranchs, however, few studies are ...

A new species of softnose skate (Arhynchobatidae) is described, based on a single adult male measuring 895 mm TL that was collected at a depth of 953–1,022 m on the Coriolis Bank off western New Caledonia in the southwestern Pacific Ocean. The specimen conforms to the genus Bathyraja in having the rostral cartilage continuous with the neurocranium and ...

A new arhynchobatin skate, Notoraja sereti n. sp., is described based on three specimens collected from off Madang (Papua New Guinea) at depths of 800–980 m. This medium-size Notoraja skate shares with other velcro skates from the Western Pacific, N. alisae, N. fijiensis, N. inusitata and N.

The most comprehensive description of variations of morphometric and meristic characters and coloration of rare deepwater pale ray Bathyraja pallida (Forster, 1967) from the North Atlantic based on all available materials is given. For the first time morphometrics are presented as percent of disc width that might be used in taxonomic studies of ...

A single specimen of a new Bathyraja skate was collected by the authors in 2003 during a survey of the deepwater biota of the northern Tasman Sea by the New Zealand FRV Tangaroa. This skate, labelled the ‘blonde skate’ by voyage participants, is uniformly white on all surfaces of the body and the skin is partly translucent.

AbstractClaspers of adult specimens of the skate tribe Riorajini, family Arhynchobatidae, comprising Atlantoraja and Rioraja, are described, compared, and systematically reinterpreted based on material collected off southeastern and southern Brazil. For the first time the external components and musculature of the clasper of members of this tribe are ...

Two softnose skate specimens with abnormal coloration, one complete albino and one partial albino (leucistic), were captured during fishery-independent trawl surveys. The complete albino specimen was collected in 2007 in Prince William Sound, Alaska, and the leucistic specimen was collected in 2011 off northern California.
