It is a multi-disciplinary project that is aimed at providing guidance on the design The IUCN SSC Shark Specialist Group met in Cali, Colombia in February to assess 100 sharks and rays that are endemic to the Eastern Central and Southeast Pacific for the IUCN Red List Photo: SSG archives of MPAs that will be optimal for achieving conservation objectives for sharks and rays. The project has developed new metrics for quantifying shark and ray movements to help inform the scale of movements relative to MPA size and applied this to large sets of satellite, acoustic and conventional tagging data. Individ- ual-based movement models have been devel- oped to enable the use of these movement metrics in the assessment of MPA efficacy, with a case study for coral reef sharks being recently published. Socioeconomic research has identi- fied indicators that predict the success of MPAs in achieving positive outcomes for sharks and rays, with five key factors identified. An online tool has been developed to allow practitioners to explore the potential benefits of MPAs for shark and ray conservation efforts at a national or regional level. This tool also collates a broad range of other data, including Red List status, An expert workshop was hosted by the Shark Trust at life history parameters, distributional infor- the National Institute of Sciences and Technologies of mation, and more, to enable users to eval- the Sea (INSTM) in Salammbô, Tunisia from the 25th – 27th March 2019 to initiate the development of this uate a broad range of data relative to MPA Mediterranean Angel Sharks: Regional Action Plan planning.

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.

  • Age, Growth and Reproductive Biology of Two Endemic Demersal
    ZOOLOGIA 37: e49318 ISSN 1984-4689 (online) zoologia.pensoft.net RESEARCH ARTICLE Age, growth and reproductive biology of two endemic demersal bycatch elasmobranchs: Trygonorrhina fasciata and Dentiraja australis (Chondrichthyes: Rhinopristiformes, Rajiformes) from Eastern Australia Marcelo Reis1 , Will F. Figueira1 1University of Sydney, School of Life and Environmental Sciences. Edgeworth David Building (A11), Room 111, Sydney, NSW 2006, Australia. [email protected] Corresponding author: Marcelo Reis ([email protected]) http://zoobank.org/51FFF676-C96D-4B1A-A713-15921D9844BF ABSTRACT. Bottom-dwelling elasmobranchs, such as guitarfishes, skates and stingrays are highly susceptible species to bycatch due to the overlap between their distribution and area of fishing operations. Catch data for this group is also often merged in generic categories preventing species-specific assessments. Along the east coast of Australia, the Eastern Fiddler Ray, Trygonorrhina fasciata (Muller & Henle, 1841), and the Sydney Skate, Dentiraja australis (Macleay, 1884), are common components of bycatch yet there is little information about their age, growth and reproductive timing, making impact assessment difficult. In this study the age and growth (from vertebral bands) as well as reproductive parameters of these two species are estimated and reported based on 171 specimens of Eastern Fiddler Rays (100 females and 71 males) and 81 Sydney Skates (47 females and 34 males). Based on von Bertalanffy growth curve fits, Eastern Fiddler Rays grew to larger sizes than Sydney Skate but did so more slowly (ray: L∞ = 109.61, t0 = 0.26 and K = 0.20; skate: L∞ = 51.95, t0 = -0.99 and K = 0.34 [both sexes combined]). Both species had higher liver weight ratios (HSI) during austral summer.

Endangered Species Act Status Review of the Brazilian guitarfish (Rhinobatos horkelii). Report to the National Marine Fisheries Service, Office of Protected Resources. SFD Contribution PCB-15-08. 2 Executive Summary This status review report was conducted in response to a petition received from WildEarth Guardians on July 8, 2013 to list 81 marine species as endangered or threatened under the Endangered Species Act (ESA). NMFS evaluated the petition to determine whether the petitioner provided substantial information that the petitioned action may be warranted, as required by the ESA. In a Federal Register notice on February 24, 2014 (79 FR 10104), NMFS determined that the petition did present substantial scientific and commercial information, or cited such information in other sources, that the petitioned action may be warranted for 10 species of skates and rays and 15 species of bony fishes, and thus NMFS initiated a status review of those species. This status review report considers the biology, distribution, and abundance of and threats to one guitarfish species from the Southwestern Atlantic, Rhinobatos horkelii (Brazilian guitarfish).
