Florida's Fintastic Sharks and Rays Lesson and Activity Packet
Florida's Fintastic Sharks and Rays An at-home lesson for grades 3-5 Produced by: This educational workbook was produced through the support of the Indian River Lagoon National Estuary Program. 1 What are sharks and rays? Believe it or not, they’re a type of fish! When you think “fish,” you probably picture a trout or tuna, but fishes come in all shapes and sizes. All fishes share the following key characteristics that classify them into this group: Fishes have the simplest of vertebrate hearts with only two chambers- one atrium and one ventricle. The spine in a fish runs down the middle of its back just like ours, making fish vertebrates. All fishes have skeletons, but not all fish skeletons are made out of bones. Some fishes have skeletons made out of cartilage, just like your nose and ears. Fishes are cold-blooded. Cold-blooded animals use their environment to warm up or cool down. Fins help fish swim. Fins come in pairs, like pectoral and pelvic fins or are singular, like caudal or anal fins. Later in this packet, we will look at the different types of fins that fishes have and some of the unique ways they are used. 2 Placoid Ctenoid Ganoid Cycloid Hard protective scales cover the skin of many fish species. Scales can act as “fingerprints” to help identify some fish species. There are several different scale types found in bony fishes, including cycloid (round), ganoid (rectangular or diamond), and ctenoid (scalloped). Cartilaginous fishes have dermal denticles (Placoid) that resemble tiny teeth on their skin. -

Spinner Shark, Carcharhinus Brevipinna
Published Date: 1 March 2019 Spinner Shark, Carcharhinus brevipinna Report Card Sustainable assessment IUCN Red List IUCN Red List Australian Least Concern Global Near Threatened Assessment Assessment Assessors Burgess, G.H. & Smart, J.J. Report Card Remarks In Australia, fishing pressure is currently well managed Summary The Spinner Shark is a common, coastal pelagic shark found in warm- temperate and tropical waters across the globe. It frequents nearshore waters and is often captured in commercial and recreational fisheries. It is sensitive to fishing pressure and habitat degradation of coastal nursery Source: CSIRO national Fish Collection. License: CC By Attribution. habitats. Little information is known on the status of Spinner Sharks throughout its distribution. Within Australia, fishing pressure is currently well managed. The Spinner Shark is assessed globally as Near Threatened (IUCN) and in Australia as Least Concern (IUCN), while Australian stocks are classified as Sustainable (SAFS). Distribution Within Australia, the Spinner Shark is found across northern Australia, from Walpole (Western Australia), throughout the Northern Territory, Queensland and to southern New South Wales (Last and Stevens 2009). It is distributed throughout the world, including the east coast of the United States, Brazil, Mediterranean Sea, west coast of Central Africa, South Africa, Madagascar and throughout the Indo-Pacific. A recent genetic study detected evidence suggesting there may be multiple, genetically- distinct stocks throughout its Australian range (Geraghty et al. 2013). Stock structure and status There is currently very little information on population size and stock status for the Spinner Shark in Australian waters. A suite of management measures introduced from 2009 have led to a substantial reduction in fishing effort targeting adults in New South Wales waters. -

Species Composition of the Largest Shark Fin Retail-Market in Mainland
www.nature.com/scientificreports OPEN Species composition of the largest shark fn retail‑market in mainland China Diego Cardeñosa1,2*, Andrew T. Fields1, Elizabeth A. Babcock3, Stanley K. H. Shea4, Kevin A. Feldheim5 & Demian D. Chapman6 Species‑specifc monitoring through large shark fn market surveys has been a valuable data source to estimate global catches and international shark fn trade dynamics. Hong Kong and Guangzhou, mainland China, are the largest shark fn markets and consumption centers in the world. We used molecular identifcation protocols on randomly collected processed fn trimmings (n = 2000) and non‑ parametric species estimators to investigate the species composition of the Guangzhou retail market and compare the species diversity between the Guangzhou and Hong Kong shark fn retail markets. Species diversity was similar between both trade hubs with a small subset of species dominating the composition. The blue shark (Prionace glauca) was the most common species overall followed by the CITES‑listed silky shark (Carcharhinus falciformis), scalloped hammerhead shark (Sphyrna lewini), smooth hammerhead shark (S. zygaena) and shortfn mako shark (Isurus oxyrinchus). Our results support previous indications of high connectivity between the shark fn markets of Hong Kong and mainland China and suggest that systematic studies of other fn trade hubs within Mainland China and stronger law‑enforcement protocols and capacity building are needed. Many shark populations have declined in the last four decades, mainly due to overexploitation to supply the demand for their fns in Asia and meat in many other countries 1–4. Mainland China was historically the world’s second largest importer of shark fns and foremost consumer of shark fn soup, yet very little is known about the species composition of shark fns in this trade hub2. -

SURVIVAL OF THE BLACKTIP SHARK, CARCHARHINUS LIMBATUS BY WILLIAM A. SWINSBURG A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE IN BIOLOGICAL AND ENVIRONMENTAL SCIENCES UNIVERSITY OF RHODE ISLAND 2013 MASTER OF BIOLOGICAL AND ENVIRONMENTAL SCIENCES THESIS OF WILLIAM A. SWINSBURG APPROVED: Thesis Committee: Major Professor David Bengtson Nancy Kohler Jeremy Collie Graham Forrester Nasser H. Zawia DEAN OF THE GRADUATE SCHOOL UNIVERSITY OF RHODE ISLAND 2013 ABSTRACT Proportional survival (S) is a crucial life-history parameter in population dynamics, natural selection, and management of harvested stocks; variations in survival due to age, sex, or geographic region may have large effects on the success of managing fish stocks. The blacktip shark, Carcharhinus limbatus, is the most abundantly harvested shark species in American fisheries. Direct estimates of survival are preferred, but all current survival estimates for this species are either focused on young-of-the-year (YOY) or based on indirect methods.
