An Annotated Checklist and the Conservation Status of Chondrichthyans in the Adriatic

An Annotated Checklist and the Conservation Status of Chondrichthyans in the Adriatic Alen Soldo, Lovrenc Lipej ABSTRACT: Although there is a high number of publications listing fish species in the Adriatic, only a few have focused on chondrichthyans, while their conservation status has been investigated even less. Thus, this paper aims to provide an updated

Utilization and trade of sharks and rays in the Andaman Islands, India Zoya Tyabji, Rima W. Jabado, Dipani Sutaria ABSTRACT: Overfishing is recognized as the most pervasive threat to sharks and rays globally. While there is increasing emphasis on ecological aspects of shark and ray fisheries, socio-economic considerations are often poorly incorporated into management policies.

Extremely low sample size allows age and growth estimation in a rare and threatened shark Peter M. Kyne, Jonathan J. Smart, Grant Johnson ABSTRACT: Understanding life history parameters is key to assessing biological productivity, extinction risk, and informing the management of exploited fish populations. Age-and-growth analyses in chondrichthyan fishes (sharks, rays, and ghost sharks) is

New shark species added to Bermuda’s fish fauna

A new species of shark, the Ragged-tooth shark (also known as the Small tooth sand tiger and, scientifically, as Odontaspis ferox), has now been officially added to list of fishes found in Bermuda waters. As often happens, the first encounter with this species was at the end of a fishing line. A commercial fishing vessel,
