Book Description
The National Marine Fisheries Service of the U.S. National Oceanic and Atmospheric Administration (NOAA), headquartered in Silver Spring, Maryland, provides information on domestic threatened species. These species are likely to become endangered. The service discusses the population, range, biology, distribution, and major threats and impacts on the smalltooth sawfish. A photograph of the smalltooth sawfish is included.
Rays of the World
Author: Peter LastPublisher: CSIRO PUBLISHING
ISBN: 0643109145
Category : Science
Languages : en
Pages : 801
Book Description
Rays are among the largest fishes and evolved from shark-like ancestors nearly 200 million years ago. They share with sharks many life history traits: all species are carnivores or scavengers; all reproduce by internal fertilisation; and all have similar morphological and anatomical characteristics, such as skeletons built of cartilage. Rays of the World is the first complete pictorial atlas of the world’s ray fauna and includes information on many species only recently discovered by scientists while undertaking research for the book. It includes all 26 families and 633 valid named species of rays, but additional undescribed species exist for many groups. Rays of the World features a unique collection of paintings of all living species by Australian natural history artist Lindsay Marshall, compiled as part of a multinational research initiative, the Chondrichthyan Tree of Life Project. Images sourced from around the planet were used by the artist to illustrate the fauna. This comprehensive overview of the world’s ray fauna summarises information such as general identifying features and distributional information about these iconic, but surprisingly poorly known, fishes. It will enable readers to gain a better understanding of the rich diversity of rays and promote wider public interest in the group. Rays of the World is an ideal reference for a wide range of readers, including conservationists, fishery managers, scientists, fishers, divers, students and book collectors.
Marine Recreational Fisheries

Book Description
"Smalltooth sawfish, Pristis pectinata, historically were found from Texas to New York. However, the population today is approximately 5% of its original size and restricted primarily to the waters of southern Florida, especially Everglades National Park adn adjacent areas (Seitz and Poulakis, 2002; Poulakis and Seitz, 2004; Simpfendorfer and Wiley, 2005). The decline of smalltooth sawfish has been attributed to catch and bycatch in commercial and recreational fishing, habitat loss, and a vulnerable life history (Simpfendorfer, 2002, 2005). In response to the decline in the population, the National Marine Fisheries Service (NMFS) listed this species as Endangered under the US Endangered Species Act in April 2003 (68 FR 15674)"--Introduction.

Book Description
The Law Library presents the complete text of the Endangered and Threatened Wildlife and Plants - Final Endangered Listing of Five Species of Sawfish (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition). Updated as of May 29, 2018 We, NMFS, issue this final rule implementing our determination that the narrow sawfish (Anoxypristis cuspidata), dwarf sawfish (Pristis clavata), largetooth sawfish (collectively Pristis pristis; formerly Pristis pristis, Pristis microdon, and Pristis perotteti), green sawfish (Pristis zijsron), and the non-U.S. distinct population segment (DPS) of smalltooth sawfish (Pristis pectinata) are endangered species under the Endangered Species Act (ESA) of 1973, as amended. We also include a change in the scientific name for largetooth sawfish in this final rule to codify the taxonomic reclassification of P. perotteti to P. pristis. We are not designating critical habitat because the geographical areas occupied by the species are entirely outside U.S. jurisdiction and we have not identified any unoccupied areas within U.S. jurisdiction that are essential to the conservation of any of the five species. We have reviewed the status of the five species of sawfish, considered public and peer review comments, and conservation efforts being made to protect all five species, and we have made our determination based on the best available scientific and commercial data that all five species of sawfish-the narrow sawfish (Anoxypristis cuspidata), dwarf sawfish (Pristis clavata), largetooth sawfish (collectively Pristis pristis; formerly Pristis pristis, Pristis microdon, and Pristis perotteti), green sawfish (Pristis zijsron), and the non-U.S. DPS of smalltooth sawfish (Pristis pectinata)-are at risk of extinction throughout all of their ranges and should be listed as endangered species. This ebook contains: - The complete text of the Endangered and Threatened Wildlife and Plants - Final Endangered Listing of Five Species of Sawfish (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition) - A dynamic table of content linking to each section - A table of contents in introduction presenting a general overview of the structure
Sharks and Their Relatives
Author: Merry CamhiPublisher: IUCN
ISBN: 9782831704609
Category : Nature
Languages : en
Pages : 50
Book Description
Sharks and their relatives, the rays and chimaeras, are the diverse group of cartilaginous fishes that have evolved over 400 million years. Historically considered of low economic value to large-scale fisheries, today many of these fishes have become the target of directed commercial and recreational fisheries around the world, and they are increasingly taken in the by-catch of fisheries targeting other species. This report emphasizes the widely-acknowledged need to improve shark fishery monitoring, expand biological research and take management action. It serves as an introduction to the ecology, status and conservation of the sharks and their relatives for a general audience. Shark fisheries can only be managed sustainably, and shark populations remain viable, with the introduction of new conservation and management initiatives.
Elasmobranch Biodiversity, Conservation and Management
Author: Sarah L. FowlerPublisher: IUCN
ISBN: 9782831706504
Category : Chondrichthyes
Languages : en
Pages : 282
Book Description
The Darwin Elasmobranch Biodiversity Conservation and Management project in Sabah held a three-day international seminar that included a one-day workshop in order to highlight freshwater and coastal elasmobranch conservation issues in the region and worldwide, to disseminate the result of the project to other Malaysian states and countries, and to raise awareness of the importance of considering aspects of elasmobranch biodiversity in the context of nature conservation, commercial fisheries management, and for subsistence fishing communities. These proceedings contain numerous peer-reviewed papers originally presented at the seminar, which cover a wide range of topics, with particular reference to species from freshwater and estuarine habitats. The workshop served to develop recommendations concerning the future prospects of elasmobranch fisheries, biodiversity, conservation and management. This paper records those conclusions, which highlight the importance of elasmobranchs as top marine predators and keystone species, noting that permanent damage to shark and ray populations are likely to have serious and unexpected negative consequences for commercial and subsistence yields of other important fish stocks.
Status Review of the Largetooth Sawfish (Pristis Perotteti).
Author: Publisher:
ISBN:
Category : Pristis pectinata
Languages : en
Pages : 57
Book Description
"This status review summarizes the biological information gathered for an Endangered Species Act (ESA) assessment of the status of the largetooth sawfish (Pristis perotteti). Species are added to a Species of Concern list as a notification to the public that the National Marine Fisheries Service (NMFS) has concerns about a species or population which may lead to listing under the ESA. The purpose of this list is to facilitate and encourage outside voluntary conservation efforts that act to prevent species from an ESA listing. It is the policy of NMFS to highlight these species before they are listed so that Federal and state agencies, Native American tribes, and the private sector are aware of unlisted species that could benefit from proactive conservation efforts. The following text explains the chronological history of the status of the species starting with its listing as candidate species."--Page 2.
